Fragrant Garden Flowers to Soothe the Senses

Fragrant Garden Flowers: Lilac (top left), clove pinks (bottom left), honeysuckle (bottom right).

Close your eyes and step into the garden. What do you smell? If you plant for aroma, you can be guided through your garden blindfolded and know what plants are there. Honeysuckle, hyacinths, lavender, and roses are as aromatically distinctive as they are visually distinctive. Fragrant garden flowers like these soothe the senses and provide a feeling of respite and calm.

Flowers are scented to lure pollinators from afar to ensure blooms are visited, pollinated, and seeds set for reproduction. Not all flowers are scented because not all pollinators have a sense of smell. In general, bees, bats, butterflies, and moths detect scents and are attracted to odorous flowers. Flowers that are night-pollinated, such as moonflower and woodland tobacco, are some of the most fragrant because night pollinators rely more heavily on smell. But, some daytime flowers, like clove pinks, honeysuckles, lilacs, and musk roses, are also highly aromatic.

Fragrant garden flowers evoke happy memories and soothe the senses. If a fragrant garden is important to you, here are some seasonal blooms that emit their enjoyable fragrance into the air to fill a space.

Scented Spring Flowers

Spice Baby™ is a compact Korean Spice Viburnum. (Image thanks to Proven Winners)

Korean Spice Viburnum (Viburnum carlesii, USDA Hardiness Zones 5-8) – Viburnums are shrubs that are typically spring bloomers with flower clusters that offer some fragrance, but Korean spice viburnum has a spicy-sweet aroma that passersby can’t miss. Uncultivated forms reach 6 to 10 feet, but there are smaller types suited to less spacious gardens. Spice Baby™ is one that reaches between 4 and 5.5 feet and has large clusters of pinkish-white flowers that will fill the air with scent in early to mid-spring.

Eternal Fragrance Daphne (Daphne × transatlantica Eternal Fragrance, Zones 6-9) – After smelling this small, semi-evergreen shrub for the first time, I had to have one. Its clusters of palest pink flowers bloom over a long period in spring and smell so sweetly they cannot be resisted. 

Goldflame honeysuckle has pink, orange, and gold flowers that smell great.

Goldflame Honeysuckle (Lonicera x heckrottii ‘Goldflame’, Zones 4-9) – The classic Japanese honeysuckle is pretty and wonderfully fragrant but an invasive brute that takes over gardens and wildlands. There are others, like the fantastically beautiful and fragrant ‘Goldflame’, which have it all without being intrusive. If you are looking for a nonstop vine for fragrance, it blooms from spring to fall. Just be sure to offer it space and prune it back as needed because its vines can reach up to 15 feet. Hummingbirds and moths visit the flowers.

Hyacinths bloom in early spring, emitting the nicest fragrance imaginable.

Hyacinth (Hyacinthus orientalis, Zones 4-8) – Traditional hyacinths appear in early spring with their colorful, upright, 1-foot stems covered with fragrant, tubular flowers of orange, pink, rose-red, violet-blue, white, or yellow. Plant these bulbs in fall for a colorful spring show and aromatic treat.

Bloomerang® Dwarf Pink is a newer reblooming lilac. (Image thanks to Proven Winners)

Lilac (Syringa hybrids, Zones 3-8) – Everyone loves the smell of lilacs, and the old-fashioned varieties have some of the best fragrance. (Click here to learn more about growing and enjoying traditional lilacs.) Some newer types also have extra fragrance. The spring-flowering Scentara® Double Blue is one of these with its clusters of double, lilac-blue flowers that emit the best lilac smell. The reblooming, pink-flowered lilac Bloomerang® Dwarf Pink is one that just reaches 3 feet and also offers a fine fragrance.

Lily-of-the-Valley is toxic, so be sure to plant it away from children and pets.

Lily-0f-the-Valley (Convallaria majalis, Zones 2-9) – The upside of shade-loving lily-of-the-valley is that it has one of the most renowned scents of all. Still, gardeners must understand that it is a fast-spreading groundcover before adding it to the garden. Once planted, it is difficult to remove. But, it is beautiful, especially when its curved wands of nodding flowers bloom in spring scenting the entire yard.

Scented Summer Flowers

New clove pink varieties are reliable rebloomers that flower through summer.

Clove Pink (Dianthus hybrids, Zones 5-9) – Old-fashioned pinks that smell of sweet clove are back in fashion. Popular plant vendors are breeding new types that bloom for longer but look like they came out of a 1900s flower catalog. The English Devon Cottage™ ‘Pinball Wizard’ is one with cuttable, carnation-like flowers with a powerful sweet clove fragrance. Those in Proven Winners’ Fruit Punch® series are also highly fragrant, long-blooming, and come in many grand colors.

Sweet peas are easy to grow but prefer milder summer weather.

Sweet peas (Lathyrus odoratus) – Commonly planted from seed as spring annuals, sweet peas grow best where summers are milder and don’t have scorching temperatures. Their flowers come in lots of colors and emit a distinct sweet fragrance that bees love. They are most fragrant in the evening, so plant them near a porch or patio to be enjoyed. Sweet pea lovers should try the Sweet Pea ‘Heirloom Fragrance’ Seed Collection from Select Seeds.

Lavender smells fantastic even when it isn’t in bloom.

Lavender (Lavandula species) – All lavenders have fragrant foliage and flowers, but species vary widely in hardiness. I favor compact, hardier forms, such as Munstead (Lavandula angustifolia ‘Munstead’, Zones 5-9) with its wonderfully fragrant lavender-blue flowers, and Hidcote (Lavandula angustifolia ‘Hidcote’, Zones 5-10), which has silvery foliage and lovely lavender flowers. Be sure to grow them in very well-drained soil and full sun. (Click here to learn more about growing different lavenders.)

‘Gertrude Jekyll’ is an award-winning rose with outstanding fragrance.

Roses (Rosa hybrids) – When choosing a rose for fragrance, keep in mind that not all are fragrant. Many hybrids bred for disease resistance, and repeat bloom lack the classic scent that we associate with roses. English roses with a strong fragrance, particularly David Austin Roses, are some of my favorites. The flouncy ‘Gertrude Jekyll‘ (Zones 4-11) is a highly-scented, reblooming pink variety that BBC Gardener’s World viewers voted as England’s favorite rose. It’s a good one for any garden.

Gulf Winds Mix sweet alyssum is powerfully scented. (Image by Jessie Keith)

Sweet Alyssum (Lobularia maritima) – Named for its honey and spice-scented flower clusters that bloom from spring to fall, sweet alyssum is a favorite bedding and container plant. It is versatile, low and spreading, and can withstand the cool temperatures of spring and fall as well as the heat and drought of summer. The common form has white flowers, but there are also varieties with lavender, rose, apricot, and purple flowers. The seed-grown varieties in the Gulf Winds Mix have very highly scented flowers.

Scented Late Summer and Fall Flowers

Moonflowers are huge and open in the evening.

Moon Flower (Ipomoea alba) – Famous for use in moon gardens, moonflower vines are tropical and commonly grown as annuals in temperate zones. They are started from seed and begin to bloom in late summer and continue into fall. The huge, white flowers reach up to 7 inches across and bloom at night to attract the moths that pollinate them. The evening is also when they emit their sweet fragrance. Vines can reach up to 15 feet, so offer them a strong fence or trellis to twine up.

Woodland Tobacco (Nicotiana sylvestris) – Award-winning woodland tobacco is a tall annual reaching up to 4 feet that bears loads of long-tubed white flowers that attract long-tongued moths. Like moonflower, they begin to emit their strong, sweet fragrance in the evening, so plant them where their night scent can be best enjoyed. Woodland tobacco tolerates full to partial sun.

Growing Scented Flowers and Shrubs

Aside from lily-of-the-valley, all of these plants are sun-lovers that will grow well in fertile soil with good drainage. We recommend amending garden beds with Black Gold Garden Soil or Garden Compost Blend to increase soil fertility. Keep them moderately irrigated after planting and feed them with quality fertilizer for flowering plants. (Click here for detailed steps for planting shrubs.) Container-grown annuals, like sweet alyssum, grow best in all-purpose potting soils with good drainage, such as Black Gold All Purpose Potting Mix.

Plant some of these fragrant garden flowers to make those warm summer days and nights even more enjoyable. Many also make superb cut flowers for indoor enjoyment.

Why Do My Sweet Alyssum Keep Dying?

Why Do My Sweet Alyssum Keep Dying?

“Every year I try planting alyssum and within 48 hours of planting its dead? I’ve tried many different things but can’t seem to get it to work at this house.  I’ve grown it in other beds and borders just not working here … any thoughts?” Question from Kyla of Oakbank, Manitoba, Canada

Answer: Sweet alyssum (Lobularia maritima) is a common bedding plant that originates as a seaside plant from the coasts of the Mediterranean and Europe. It can withstand the cool temperatures of spring as well as the heat and drought of summer, but there are several things that are certain to kill it early in the season. Here are the top four possibilities.

  1. Below-freezing temperatures – Spring-purchased alyssum plants have been greenhouse-grown and are more tender than average and sensitive to temperatures near or below freezing. Once well-established and growing, they can take light frost.
  2. Poor drainage – Maritime plants like alyssum are adapted to very sharply drained soils. They will grow well in organic-rich soils if they are porous and have very good drainage. Pot-grown specimens require a mix with good drainage, such as Black Gold All Purpose Potting Mix. The containers also need to drain well through holes at the bottom.
  3. Cold, wet weather – Cold, wet weather can induce fungal disease and subsequent root and crown rot.
  4. Poor Irrigation before establishment – Newly planted annuals need even moisture and good care while they are becoming established. If they are not properly watered from the start, they can dry out and die quickly. Those planted as small plugs are especially susceptible to drying because they have tiny root systems.

If your plants are subjected to one or more of these stresses shortly after planting, death can occur. But, below-freezing cold is the fastest killer. I hope that these tips help!

What Are Some Slender Shrubs for Small Garden Spaces?

Slender Shrubs for Small Garden Spaces

“I have a spot on the front of my house that gets morning sun. Our house faces east. The spot is about 6 feet x 4 feet. I’d like to find a shrub that grows tall and skinny.” Question from Jen of Sycamore, Illinois

Answer: There are many slender shrubs for small garden spaces that are just tall and skinny enough to fit in your partially sunny bed. My suggestions only include shrubs that will not overgrow the spot. All are tolerant of partial sun.

  1. Stonehenge Skinny Yew stays upright, slender, and reaches just 8 feet when mature and 2 feet across. It is also tough, evergreen, and hardy to USDA Hardiness Zone 5.
  2. Sky Pencil Japanese Holly is a classic upright evergreen shrub that remains very slender–to 18 inches across- and only reaches 6 feet high.

  3. Filips Magic Moment’ Arborvitae is conical, upright, has golden evergreen foliage, and reaches 8 feet x 3 feet. It is also very hardy.
  4. Columnar Apple Trees can reach 8 feet and stay just 2 feet across. You need at least two for cross-pollination and fruiting, but you may have space for a couple. The spring flowers are very pretty.
  5. Fine Line® Buckthorn has fine, feathery leaves and reaches a maximum of 7 feet and only 2 to 3 feet across. It is a simple, and attractive choice.

Can I Grow Green Beans in a Greenhouse?

Can I Grow Green Beans in a Greenhouse?

“Can I grow green beans in a greenhouse?” Question from Angie of Fort Bragg, California

Answer: Absolutely. Green beans, whether pole beans or bush beans, can be grown in a greenhouse if given good soil, full sun, regular moisture, and temperatures that do not get too hot. Green beans grow best in temperatures between 50 and 85 degrees F. If you have only a small space in which to grow, I recommend bush beans. If you have a hoop greenhouse with a soil floor then you can grow pole beans in-ground.  I encourage you to watch the video about growing beans to learn more about raising these tasty summer vegetables.

Why Did My Iris Take So Long to Bloom?

Why Did My Iris Take So Long to Bloom?

“Why Did My Iris Take So Long to Bloom? I planted Irises about three years ago & this is the first year they have bloomed. Is that normal?” Question from Rosie of Wichita, Kansas

Answer: I am going to assume you are growing German bearded iris (Iris germanica), the most common iris variety in the United States. There are lots of factors that may have caused yours to be late in blooming, such as small starting size or less-than-ideal growing conditions. Since I am not certain of your plant’s garden conditions, let me simply share what German iris need to thrive.

These popular garden flowers perform best when given full sun and fertile, well-drained soil conditions. (I recommend adding Black Gold Garden Compost Blend if your soil is low in organic matter.) Bearded iris rhizomes should be planted with the tops at or slightly above the soil surface, as those planted too deeply may result in lush foliage but fewer or no flowers. Late spring freezes, which can halt early stem and bud development after the plant has sprouted, are another common cause for lack of flowering in bearded irises. Other factors that might have impacted the delay in blooming are lack of sufficient sunlight, poorly drained soil, or insufficient soil nutrition.

I hope that these insights help. And, if you think there are some improvements that can be made to the growing conditions of your iris, I encourage you to make them. It is always wonderful when iris are in full bloom in spring.

Happy gardening,

How Should I Irrigate My Santa Rosa Plum Tree?

How Should I Irrigate My Santa Rosa Plum Tree?

“How often should I water with drippers my 20-year-old Santa Rosa plum tree?” Question from Gloria of Morgan Hill, California

Answer: Even established trees with deep roots need supplemental water during dry spells. In arid areas where soils are poor, irrigation is even more important, as is fertilization. Let rainfall decide when you irrigate your Santa Rosa plum tree (Prunus salicina ‘Santa Rosa’). During extra dry periods, you may need to water it two to three times a month. Remember that tree roots flare out, and most feeder roots are along the periphery of the flare, so avoid just watering near the trunk. The flare often follows a tree’s branching, so water further out to really irrigate properly.

Plum trees grow best in fertile soils that drain well. Adding a layer of compost, such as Black Gold Garden Compost Blend around the roots each year can help slowly feed the soil and hold in needed moisture.

When Is It Safe To Plant Summer Annuals?

When Is It Safe To Plant Summer Annuals?

“When is it safe to plant summer annuals? Should I wait until after Mother’s Day to plant my marigolds, petunias, and other annuals?  I live in Central Ohio.” Question from Diane of Newark, Ohio

Answer: Always plant warm-season annuals, like petunias and marigolds, after the threat of frost has passed. To do this, you need to know your last frost date. The Old Farmer’s Almanac provides this data. Every gardener should know both their first and last frost dates for the growing season. Here is the data that is yielded when I search using your Zipcode:

 

Nearest Climate Station Altitude Last Spring Frost First Fall Frost Growing Season
NEWARK WATER WKS, OH 836′ May 4 Oct 6 154 days

 

To be safe, I always plant at least a week after my last frost date–especially if the weather has been temperamental. When planting your flowers, be sure to feed them with a fertilizer formulated for flowering plants, such as Proven Winners® Continuous Release Plant Food, and amend the soil with Black Gold Garden Compost Blend or Canadian Sphagnum Peat Moss to improve its structure and fertility

How Long Does Compost Feed Plants?

How Long Does Compost Feed Plants?

“How long does compost feed plants? And if you have compost in the ground, do the plants still need fertilizer? I use plant-based food scraps, grass clippings, and shredded paper for trench composting. It breaks down very quickly here in the Sonoran Desert.” Question from Jacqueline of Casa Grande, Arizona

Answer: The value of compost to plants depends on how long it takes to break down. Compost adds needed structure, water-holding capacity, aeration, and microorganisms to garden soil. Overall, it feeds and enriches soil, but its nutrient profile depends on what you feed into your compost pile. For example, if you add lots of eggshells your compost will have higher calcium content. With that said, you should also add balanced fertilizer to your garden beds–especially where soils are nutrient-poor. As your compost breaks down and disappears, it is no longer working its magic, so keep it replenished. And, if you run out you can always supplement further with products that are high in organic matter, such as Black Gold Garden Compost Blend, Just Coir, or Canadian Sphagnum Peat Moss.

Why Aren’t My Roses Growing?

Why Aren’t My Roses Growing?

“Why aren’t my roses growing? My rose bushes do not grow, and I fertilize them once a month, but they don’t grow.  Soil is clay-like.  They are semi-shade, I have a lot of big trees. They do flower.  What else can I do?” Question from April of Dresden, Tennesee

Answer: There are three key factors that are likely keeping your roses from growing, thriving, and flowering to their fullest. They are:

  1. Sunlight: Roses need full sun to grow and flower at their fullest. Six hours per day is the bare minimum they need to really perform well. Eight to twelve hours is even better. The morning sun is preferable to dry leaves early in the day, which dissuades fungal diseases.
  2. Soil: Roses require a fertile, well-drained soil that is slightly acidic (pH 6.5-7) and high in organic matter to perform at their fullest. Amend the soil where they are planted to encourage better root growth and performance. Black Gold Garden Soil and Black Gold Canadian Sphagnum Peat Moss are two excellent amendments to consider
  3. Competition: Tree roots quickly drain water and nutrients from the soil. It is wise to plant roses away from tree roots to avoid competition.

What Are the Best Strawberry Varieties for Texas Gardeners?

What are the best strawberry varieties for Texas?

What are the best strawberry varieties for Texas? I really would like to enjoy them year-round, and I have the ability to grow them in a raised bed that can easily be covered.” Question from Deb or Alvarado, Texas

Answer: Great timing! I just planted 25 strawberries in my own Delaware garden, so strawberries are on my mind. There are two types of strawberries, June-bearing types that produce once a year, and everbearing types that produce one big crop in late spring and then keep yielding additional berries through the season. It sounds like you want the latter. Additionally, some strawberries are better adapted to warmer zones like yours. Three everbearing recommendations for southern gardens like yours include ‘Tribute‘ (medium-fruited, disease-resistant), ‘San Andreas’ (extra-large fruited, heat-tolerant), and ‘Seascape‘ (medium-fruited, disease-resistant). There are many more, but these three are very good choices that are commonly available.

Growing Strawberries

Strawberries grow best in soil that is well-drained, moisture-retentive, light, and high in organic matter. A soil with a slightly acid pH, between 5.5 to 6.5, is ideal. Amending with Black Gold Garden Soil, Peat Moss, or Compost Blend will boost your raised bed soil for strawberry growing. For further growing information and planting guidelines, please watch the video below.

Enjoy your strawberries.
