Hosta Plant Flowering: What To Do About Flowers On Hosta Plants


By: Teo Spengler

Do hosta plants have flowers? Yes, they do. Hosta plants grow flowers, and some are lovely and fragrant. But hosta plants are known for their gorgeous overlapping leaves, not for hosta plant flowers. Read on for information about flowers on hosta plants and for an answer to the question: should you let hosta grow flowers.

Do Hosta Plants Have Flowers?

Every hosta plant grows flowers. But not every hosta plant flowering is a welcome sight to the gardener. Many gardeners select hostas for the shade garden because of their lush foliage, not hosta plant flowers. The mounding leaves of cultivars can be spectacular, ranging in color from standard green to blues, white and gold. They also come in many shapes, sizes and textures.

For example, if you want a very small hosta, you can plant “Baby Bunting” that even at maturity is only a few inches wide. Other hosta plants, like “Blue Angel,” can grow to over 8 feet (2.4 m.) in diameter. Because of this emphasis on foliage, hosta flowers can be viewed as an extra plus for the plant. They can also been seen as a distraction from the main show.

Flowers on Hosta Plants

Hosta plant flowering can be a very fancy affair. The plants flower in summer, offering spikes of blossoms that look like lilies, in shades of lavender or white. The bell-shaped blooms can be showy and exceptionally fragrant, attracting hummingbirds and bees.

New cultivars are being developed that offer even larger, more impressive blooms. Some offer up to 75 flowers per stem. In short, hosta flowers can add ornamental value to a hosta plant. Yet, many gardeners still ask: should you let hosta grow flowers?

Should You Let Hosta Grow Flowers?

Whether you want pure foliage or will accept hosta plant flowers is a matter of personal taste. Each gardener must make up his or her own mind.

The quality of the blossoms your hosta plant flowering produces might influence your decision. Many gardeners like tall flower scapes, but not every plant produces them. Sometimes, especially with the white-flowered hostas, the flower scapes are awkwardly short and stunted.

And whether or not you allow them to bloom, you’ll want to clip the scapes when the blossoms fade. Faded hosta flowers are not attractive.

Instructions

Use garden shears to cut off seed heads.

  • Hosta, also known as the plantain lily, has beautiful foliage that changes color in the fall and winter.
  • The tall stems make it a good cut flower to use in arrangements, but the seed heads can be left on the plant to add interest during the winter months.

Cut hosta foliage. Hosta foliage begins to die down on its own, but it benefits from cutting back.

Gently bend the foliage back until you can see where the leaves meet the rhizomes (roots.) Begin cutting foliage until all the leaves are cut back. Hostas planted in tubs should also be cut back in early to late winter.

Mulch. Mulch hostas growing area with 2-4 inches of mulch. Hostas benefit from heavy mulching. The perennial will come into leaf in late spring.


Fall Hosta Care 101

Cutting Back Hosta Plants

By mid fall, hosta plants begin to slowly lose their luster. Their once leafy, overflowing foliage begins to fade to fallish shades of brown and yellow.

As autumn progresses and the temperatures continue to chill, the plant quickly deteriorates. Especially if a frost or light freeze hits and kills the foliage back completely.

A hard frost or freeze can spell a quick end to a hosta’s leafy green foliage.

And once a good portion of a hosta’s leaf structure begins dying back, it’s a signal that the foliage and stems need to be clipped. As a good rule of thumb, if 25% or more of the plant is dying back, it’s time to cut it back!

So why is cutting back so important?

For starters, decaying stems and leaves maker for some pretty unsightly flowerbeds. But even more importantly, leaving the rotting foliage allows pests and disease a perfect place to find a home.

As your hosta plant begins to decay significantly, it is time to cut it them back for winter.

And if kept around all winter, they lay silently dormant, only to come back to life even stronger next spring to become serious issues for your plants.

Cutting Back Hosta Plants – Fall Hosta Care

The good news is, cutting back hosta plants couldn’t be easier. The loose foliage and stems cut easily with garden shears, or even a sharp pair of scissors. Simply lift up the foliage, and snip the plant to within a few inches of ground level.

Hosta plants should be cut to within a few inches of the ground in mid to late fall.

As for the foliage remains, as long as it does not show obvious signs of disease or pest infestation, it’s a great addition to the compost pile. Now that the plant is cut back, it’s time to determine if your hosta needs to be divided.

Splitting and Dividing – Fall Hosta Care

Fall is the perfect time to dig up and divide overgrown hostas. Plants whose roots have become too large not only bloom less in subsequent years, but become more susceptible to pest and disease with their massive canopy of foliage.

A good rule of thumb is that hosta plants should be divided every 3 to 5 years. If your plants have become overly large and are having trouble blooming, now is the time to dig them up and divide.

When hosta plants grow too large, their roots become compacted, and the plant suffers. Dividing every few years keeps plants at their best.

Although this can be done in the spring, dividing and transplanting in the fall allows the hosta crowns time to establish before winter. This results in hostas that have much better first year growth patterns than spring transplanted plants. (See : How To Divide Perennials In The Fall – 7 Secrets To Success)

New Fall Transplants – Fall Hosta Care

Just a quick note on late season transplants. Depending on the weather, new divisions and transplants may send up new shoots before winter sets in. This is completely normal and does not hurt the plants in any way.

It simply means that the roots have become well established in the cool fall soil. A hard frost or freeze will eventually kill back the new growth, and the plant will head into dormancy for the winter months.

New transplants may send up shoots in late fall if the weather remains warm enough. It will not harm the plant, as the new growth will die back with the first frost.

One thing you should not do in the fall is fertilize your hosta plants. Fertilizing can promote too much growth, especially if the temperatures happen to stay warm. Instead, as you will see below, you can provide a bit of slow-growth nutrients with compost.

Mulching For Winter Protection – Fall Hosta Care

Once plants have been cut back and any divisions and transplants needed have been made, it’s time to give the plants a protective layer of mulch before winter.

The fall mulching of plants is one of the most underrated chores of all. But it really can make a big difference in keeping perennials strong.

Mulch helps insulate the plant’s roots against temperature swings. Swings that can cause excessive freezing and thawing that can injure or even kill off plants.

In addition, mulching also helps keep competing weeds and weed seeds from blowing in and taking over. (See : Mulching Fall Flowerbeds, How To Stop Next Year’s Weeds Now)

For fall mulching, begin by putting a light covering (1 inch) of compost over the crown of each plant. Next, place a two to three inch layer of traditional mulch all around the plant.

Why the compost? Not only will the compost provide a bit of insulation, it also acts a slow release fertilizer for plants come next spring. It is especially helpful for new divisions and transplants to have added nutrients come spring.

Here is to putting your hosta plants to bed for winter with the proper fall care, and enjoying healthy blooming plants next spring!
