“I’m looking for asparagus that will grow in USDA Hardiness Zone 10b.” Question from Lori of Venice, Florida
Answer: Asparagus generally survives in USDA Hardiness Zones 3-8 and requires a winter dormancy period to successfully grow and produce spears. In northern regions, plants can produce for up to 30 years, but they don’t tend to fare well down south where winters are warmer.
With that said, some varieties will produce spears in Central Florida, but they generally stay productive for just three to five years. One of the best of these varieties is the California-bred ‘UC-157’. (Click here for a good source.) This is the asparagus that you want to grow in your part of the world.

Happy asparagus growing!
