Cannas for Color All Summer by Mike Darcy

Big, bold, bodacious & beautiful, cannas are a superb plant for providing color all summer. Not only will cannas produce flowers but some of their spectacular foliage can make them a colorful plant in the garden even when not in bloom. Cannas are well adapted to growing in a garden bed or in a container. Planted in the ground, cannas can make a very striking mass of color with their large leaves and flowers.  They also make excellent container plants and are ideal for a small space garden or on a deck or patio. 

Cannas have a starch rich rhizome and have been cultivated for hundreds of years. Most of the species available today are from the American tropics and subtropics and in their initial introduction to gardens, they were considered tropical plants. While it is true that they are tropical, they are what I would call a ‘hardy’ tropical that can be successfully grown as a summer plant in most temperate zones in the United States and can be an easy and low maintenance plant.

In my own garden, in western Oregon, I like to grow them in containers on our deck. Our deck is in full sun and they thrive and bloom all summer. My soil choice has been either Black Gold Moisture Supreme Container Mix or Black Gold Natural & Organic Potting Mix. For growing cannas in a container, a large pot is best, it is amazing how much a plant can spread in just one season.

 

There are lots of choices with the diversity of cannas regarding flower color, foliage pattern, and the height of the plant. The tall growing types are idea for the back of a mixed flower bed which when selecting a plant, it is important to consider the space and the desired height.

For a fun and novelty canna that probably grows much too tall for most container planting is Canna musifolia, often called the Banana Canna. This is a tall grower and has the common name of Banana Canna for a reason, it grows fast and tall, often 8 feet or more!

As I mentioned, the canna choices are vast and below are couple of my favorites that are growing in my garden this summer. When visiting a garden center, there will be many more than what I mention here.

 

Canna pretoria ‘Bengal Tiger’ is known for the very attractive striped foliage. While this canna has vivid orange flowers, even when not in bloom, the foliage makes this a very colorful and attractive plant. It is a great choice for a pot on a deck or patio.

 

If I was picking a favorite, it would have to be canna ‘Cleopatra’. This canna has both multicolored leaves and flowers. Some leaves will be all green, some will be a dark bronze, and often a leaf will be a mix of the two colors while some will be green with a single stripe of bronze. The flowers are equally diverse in color. They can be all red, all yellow, (sometimes with spots), and a flower can be half red and half yellow. It makes a great conversation plant!

Red Gold Flame was new to me last year and is a lower growing type which makes it idea for a small space. It was never without a flower.

As mentioned earlier, cannas are a tropical plant and may need some winter protection depending on the region they are growing in. In western Oregon, when planted in the ground and with good drainage and a mulch covering, they will often survive a winter. Being in a container, they are more vulnerable to the elements, and it is a good idea to give them winter protection. Once cold weather arrives, I cut the stems back to the soil level and lift plant out of the container and shake off excess soil. Not having a greenhouse or basement, I put the rhizomes in a large plastic container and cover them with peat moss and then store the container in our unheated garage. This has worked for me for many years and in the spring, they are ready to plant.

Most garden centers will have a good selection at this time and the plants will probably be in bloom. If you have never grown cannas, give them a try and I think you will be pleasantly surprised at the color they will provide for the balance of the summer.

Head in the Sun, Feet in the Shade by Mike Darcy

Head in the Sun, Feet in the Shade

Known as the “Queen of the Vines”, clematis have long been a favorite in many gardens. The name, clematis, is from the Greek word clema which refers to a tendril or vine branch and the correct pronunciation is Klem-ah-tiss but it is often pronounced as kle-MAH-tiss. Regardless of how it is pronounced, I don’t think the plant really cares!

Clematis are often thought of as on old-fashioned flower, and they are. The first hybrid was introduced to gardeners in England in 1862 by an English nurseryman with the name of George Jackman. The name of his plant, Clematis ‘Jackmanii’. In that early time period, many early clematis were named for members of the nursery that was raising them. Actually, that is often still the case today and not just with clematis but many other plants as well. Now, over 150 years since its’ introduction, Clematis ‘Jackmanii’ is still a well-known and a very popular clematis.

There is a huge diversity within the genus clematis, not only with regard to the color of the flowers, but the shape of the flower, the growth structure of the plant, and the time of flowering, A popular slogan regarding selecting a location for a clematis is “Head in the sun, feet in the shade”. Basically, “the head in the sun” refers to clematis as liking 5-6 hours of sun, and “the feet in the shade” refers to clematis as liking their roots in the shade with a cool damp environment. A garden mulch should be thoroughly worked into the soil at time of planting and then also using the mulch to also cover the soil. Black Gold Natural & Organic Cocoblend Potting Mix would be an excellent material to use because of the moisture retention quality of coir. Often gardeners will plant a ground cover around the roots as well.

Most clematis are deciduous, and most are climbers and will need some kind of support, which could be a trellis or arbor and often gardeners will plant a clematis at the base of an established shrub. The clematis will then grow into the shrub and perhaps will bloom after a shrub has finished. However, Clematis armandii is an evergreen type and has a very vigorous growth habit. There are also some non-vining types that can be used as a ground cover. Recently there have been some newly developed hybrids that have been bred to be adapted to growing in a container.

Fuchsias, Everbloomers All Summer by Mike Darcy

Fuchsias, Everbloomers All Summer

With the month of May, the garden season is in full swing. Garden centers are bursting at the seams with new shipments of plants and for many gardeners this is the month to purchase plants for the summer garden. Whether for flower color or foliage, there is a vast selection to choose from. Sometimes it is like being on ‘overload’ with the choices we have. Often, for many gardeners it is difficult to limit the amount and selection of plants that we buy and often with defer to the adherence of the phrase that “there is always room for one more”.

One group of plants that stands out for continuous summer flowers is the Fuchsia. In addition to the flowers, there is diversity with the foliage that can provide color as well. There are also different growth habits of fuchsias, with some that are trailing and will make an excellent addition for hanging baskets or plant them in a large pot to trail down the sides. There are many upright varieties that are well suited for planting in the ground and will also provide some upright structure in a container. Be sure to check out a relatively new group called “Hardy Fuchsias” that tend to have a more upright form and are being bred to withstand winter temperatures in many parts of western Oregon and Washington.

Considering their native environment of South and Central America where they are concentrated in cool, moist tropical and subtropical regions, the potting mix they require is very important. Black Gold has several good choices and my preference for containers is Black Gold Natural & Organic Potting Mix. For ‘hardy fuchsias’ that will be planted in the ground, plant them about four to five inches deeper than the soil level in the pot and this will help the plants survive the winter. For fuchsias in the ground, I would suggest Black Gold Natural & Organic Cocoblend Potting Mix. Coir is a material that is extracted from the fibrous outer husk of a coconut, and it has excellent moisture retention.

Fuchsias bloom on new growth and a regular fertilizer routine is recommended for continued flowering. Pick off the old flowers as they fade. With so many choices and diversity, it is difficult to pick a favorite, but the following are four that I have had in my garden for several years and I find them very dependable, continuous bloomers, hummingbird magnets, and generally pest free.


Fuchsia magellanica has been in my garden for more years than any other fuchsia that I have. When we have had some very cold winters, the plant will die to the ground, but new growth reappears the following spring. This past winter was quite mild and there was no die back. Because of that my plant, which is growing against a support structure, is now over 8 feet tall and is covered with drooping small red and violet flowers.
Fuchsia ‘Tom West’ has everything going for it. It has a trailing and mounding habit of growth which makes it excellent for containers. With variegated leaves, it looks good even when not in bloom. Give it some protection from the hot afternoon sun. This fuchsia won the Royal Horticulture Society Award of Garden Merit in 2015. It is very deserving of this award.

Fuchsia ‘Debron’s Smokey Blues’ is an upright compact shrub with single flowers that have magenta sepals and deep purple corollas. When I saw this outstanding color combination in a garden several years ago, I knew that I needed one. In addition to the outstanding flower color, the foliage tends to be a light blue green.

Fuchsia speciosa is a hybrid with parentage from Central America and Mexico. It has some unique characteristics, primarily the long red-orange tube shaped flowers and the heart-shaped leaves that have a velvet-like feel to the touch. This is best in a location with some shade where it will reach about 3 ft in height. This fuchsia dies to the ground in the fall and needs to be heavily mulched for the winter.

I have barely touched on the hundreds of different fuchsias that are available. This is an ideal time to buy them because most will be in bloom, and you can be sure of getting the color you want. There is room for a fuchsia even in gardens with limited space or decks and patios where they can be grown in containers. Not only will they provide color all summer, but they are good pollinator plants and a big hummingbird attractant.

Hello to Hellebores by Mike Darcy

There are some plants in the garden that when they appear, it is a signal that spring is on the way. The Peony is one and I think when the new growth sprouts from the ground, it is a way of saying that winter is over and spring is here or will be soon. However, even before the peony new growth appears, the hellebores have beaten them by announcing that they are already blooming and announcing that spring is on the way!

While native to Turkey and surrounding areas, as well as Morocco and even into temperate Asia, hellebores have long been planted in American gardens. They were, and are, an often-used plant in perennial flower beds and are especially appreciated for their early and long blooming season. In the Pacific Northwest, flowers can often appear in January and will continue for eight weeks or more. All parts of the plant are poisonous if ingested, and hellebores are one plant that is truly deer resistant. The name itself tells the story. The genus Helleborus comes from the Greek words bora meaning food and helein meaning “injures/destroys” in reference to the plant’s toxic leaves, stems, and roots.

Hellebores do well in a location with morning sun or filtered sunlight. If planted in too much shade, flowering may be reduced. They like a soil that is rich and moist with compost such as Black Gold Natural & Organic Garden Compost Blend or Black Gold Natural & Organic Earthworm Castings Blend.

 

If your garden has plantings of established hellebores, this is the time of year to do some maintenance. Carefully cut off the old leaves, being very careful not to cut a new flower stem or leaf. Removing these old leaves will allow the new leaves to spread and provide nourishment for the plant. With the removal of the old leaves, this will also make the plants more visually appealing and will help to show off the flowers.

Hellebores are hardy perennials and will live for many years. The plants form clumps which after a few years can be divided in the fall. If left to grow in a natural area, new plants will germinate from seeds. If new seedlings are not wanted, remove the flower stems before seed capsules form. In my garden, I generally let the flowers go to seed and I have some mass plantings that have occurred from new seedlings.

The flowers on hellebores are naturally nodding downward, and this can make it difficult to see inside the actual flower. Planting them on a slope can make it easier to look into the flower and being on a slope can also help improve drainage. Many new hybrids are now available and with new breeding, some flowers are less downward growing and grow more outfacing. Try floating flowers in a bowl when bringing them indoors. Outdoors at our house, we have floated them in a birdbath which can be quite attractive.

This is an excellent time to visit your local garden center and see what is available. If you have not seen some of the new hybrid hellebores, you may be surprised at the array of color available. Flowers can be single, semi-double, double, and multicolored. For an easy-care plant that produces flowers in the winter, hellebores are hard to beat.

Camellia in January by Mike Darcy

 

Sometimes I hear gardeners lament the lack of winter color in gardens but in the western part of the Pacific Northwest, there should be no complaints.  It is difficult to find a plant that can provide more winter color than the Camellia. While most are unscented, it is difficult to think of a winter blooming plant that can provide such diversity. With flower colors ranging from shades of red, pink, cream, and white, as well as many that are variegated and with blooms that can be single or double, the choices are vast. Plus, a big benefit to gardeners is that they are easy to grow.

 

Due to their diversity, it should come as no surprise that Camellias have different blooming periods depending on the particular type. With the winter season upon us, I am going to focus on Camellia sasanqua which are generally winter bloomers. A few of these Camellias will be highlighted but a visit to your local garden center will provide an idea of what is locally available.

 

While there are some very large Camellias in older established neighborhoods that are planted with no sun protection, I think they perform best with some shade, especially protection from the hot afternoon sun. Planting in a location with morning sun or filtered sunlight from trees is ideal. Some plants can grow into quite large shrubs so be sure to check the plant label as to height and width.

 

Camellias like to be planted in a soil that is moist and well-draining. Black Gold® Natural & Organic Cocoblend Potting Mix would be an ideal potting mix to work into the soil at time of planting. The coir, (coconut fiber) in this mix has excellent high water holding capacity qualities. Generally, Camellias are not deep-rooted plants and a yearly addition of a top dressing around the plant with Black Gold® Natural & Organic Garden Compost Blend would be a benefit.

 

There are many selections of Camellia sasanqua to choose from and I’ll mention several that I have grown or know friends that have. This season seems to have been and continues to be an extremely prolific blooming year.

Yuletide is a Camellia sasanqua, so named because it is usually at bloom during the Christmas season with red single flowers. It is one of the most popular of the winter blooming camellias. Yuletide’ also makes an excellent container plant and having one at an entryway can brighten a gloomy winter day. To add even more color, try planting white pansies around the base.

Showing off the diversity in flowers, a popular Camellia sasanqua that is multi-colored is ‘Yume’. This has single pink and white petaled flowers, each petal is either pink or white. It has a long winter flowering season with blooms appearing in November and continuing until March.

Another popular one and with a name that makes me smile is Camellia sasanqua ‘Pink-A-Boo’. This camellia, unlike most, has fragrant flowers. The pink flowers have bright yellow stamens and typical glossy, dark green foliage. A friend has had this growing in his garden for about ten years and it is about five feet in height and provides a nice ‘pop’ of winter color amongst other evergreen shrubs.

GIFT IDEAS FOR GARDENERS by Mike Darcy 

 

 

 

 

 

 

 

Selecting a gift for a gardener is not as easy as it sounds. Depending on how well you know the gardener and the garden, it can be challenging to select a gift that would be both useful and desirable.

 

Gifting a plant would seem logical but it is not as logical as it may sound. Most gardeners have ideas on the plants they want and by gifting one that is not particularly wanted, can create stress to the receiver. What to do with an unwanted plant!? Unless it is a holiday plant that is disposable, like a poinsettia, amaryllis, cyclamen, or something similar, I would shy away from gifting a plant unless I knew the gardener well.

 

Thinking about my own garden and what I might want and talking with other gardeners, the following suggestions are items that would be useful to most gardeners.

Thinking about my own garden and what I might want and talking with other gardeners, the following suggestions are items that would be useful to most gardeners.

A fun, practical and useful host/hostess gift would be a small bag of Black Gold®Natural & Organic Seedling Mix. This would be a unique gift! A fun supplemental gift to go along with the seedling mix would be a package of Cow Pots. These are made from composted cow manure and can be planted in the soil along with the seedling. They are odorless and non-toxic and come from cows that are fed healthy diets that receive no growth hormones. I think that a combination of these two items would be the most talked about gift at a party!!

Nearly every gardener can use a new pair of gloves and instead of a regular pair of garden gloves, why not go above and beyond and get a pair of goatskin gauntlet garden gloves. Roses have thorns, as well as many other plants, and goatskin gloves are soft to the touch, and the gauntlet offers protection to hands and wrists.

 

If the gardener likes to write, a garden journal might be an appropriate gift. It can provide a record of planting dates and harvests, temperatures, pests, flowering times, and reminders of things to do, However, a journal can be so much more than just a listing of the chores of gardening. It can describe how the garden makes you feel, is it peaceful, a place of solitude, does it give you a feeling of contentment, these are just a few of the feelings a garden can emit.

 

 

 

 

 

 

 

A pair of high-quality hand pruners can be a superb gift. Many gardeners, myself included, are quite often mis-placing a pair of hand pruners. They are not actually ‘lost’ but have disappeared someplace in the garden and are most likely to reappear at a later date. In the meantime, a backup pair is a necessity. To go along with a hand pruner gift, or as a stand-alone gift, consider a garden shear sharpener. Gardeners like to have sharp shears and to have their own shear sharpener could make a much-appreciated gift.

 

 

There is a strong movement to help native insects and especially pollinators. Mason bees can easily be attracted to most gardens and are a welcome insect for early season pollination. They are non-aggressive, solitary bees that build nests in tunnels. Special Mason bee nesting tubes are available and would be an innovative gift.

 

 

Many gardeners feed birds at some time during the season and several suet cakes or bags of bird seed can be a gift any gardener could use. Suet cakes can have a variety of things mixed into it including dried fruit, corn, sunflower seeds, and even dried insects. Different mixes will attract different kinds of birds.

 

 

 

 

 

 

 

These are just some ideas for gift giving this holiday season. Hopefully this collection will be of help in selecting a gift to a gardener and perhaps you’ll find something that would be a new and needed addition to your own garden.

 

HAPPY NEW YEAR!
