Perennials: Plants that Keep On Keepin On’
Perennials have been a hot gardening topic for years. People love that they can plant perennials one time and not have to re-plant for many years. The term perennial can be confusing for a few reasons. Hopefully, I can help clear common confusion about the word perennial. Annuals live for one season and you have to plant them annually. Perennials return year after year. Some synonyms for the word perennial are continual, longstanding, persistent, and recurrent. Planting perennials in fall makes the spring season easier for years to come.
Different Types of Perennials
With this knowledge, it is easy to recognize that trees, shrubs, evergreens, and many flowering plants are all perennials. However, in the garden industry, we often think of “perennials” as a group of flowering plants that return for several years. While all these trees, shrubs, perennials, and bulbs are often perennial in nature, we don’t refer to all of them as just perennials.
Typically, when you hear the term perennial in a garden center or an online garden store like Holland Bulb Farms they are referring to a herbaceous plant that returns for several years. What is a herbaceous plant? Herbaceous plants have fleshy stems and leaves, as opposed to a woody plant like a tree or shrub that has woody stems, branches, and trunks.
Many flower bulbs such as daffodils, allium, and tulips are considered perennial from a botanical stance, and they are herbaceous. However, they are often categorized as bulbs since that is where the above-ground parts of the plants grow from. Yes, they are perennial and herbaceous and you can certainly refer to them as perennials but calling them bulbs is more common.
Now that we have defined some common garden terms and cleared up any confusion between the difference between bulbs, herbaceous perennials, and woody perennials, let’s talk more about fall-planted perennials.
Flowers to Plant in the Fall for Spring
Spring is the biggest planting season for perennial plants. People like to plant perennials early in the season so they can enjoy them for that spring, summer, and fall. However, it is not necessary to limit your perennial planting to spring. There are plenty of interesting perennials that can be planted in fall and will thrive the following spring. If you want to get a jump start on next season and plant some perennials this fall continue reading for 10 perennials to plant this fall.
10 Perennials to Plant This Fall
Harlem Oriental Poppy
Oriental Poppies are popular perennials that bloom near the end of the spring season. Harlem Oriental Poppy is a deep raspberry red poppy that has a long bloom time.

Plant with bearded light pink iris and white allium for a late spring trio of blushing beauties.

When you think of poppies you most likely think of the red/orange varieties like Turkenloius Oriental Poppy.

Perry’s White Oriental Poppy looks nice in a moonlight garden or any part of the yard you enjoy at night as the white blooms glow in the darkness.
David Tall Phlox
The Perennial Plant Association didn’t designate it as the 2002 Perennial Plant of the year for no reason! David Tall Phlox features clusters of pure white flowers late in summer. Plant David Phlox this fall and next summer you will have a jump start on the growing season. Many tall phlox varieties are susceptible to powdery mildew which causes white spots on the leaves and can weaken the plant; one of the best features of David Tall Phlox is that it is mildew resistant.
