Hosta flowers

Hosta flowers can be both beautiful and incredibly fragrant. While hostas are most commonly grown for their beautiful foliage, their flowers are also well worth admiring!

Hosta flowers grow on tall thin flower stalks up above the mound of leaves. Most hostas have pale purple or white flowers that are bell-shaped or funnel-shaped. The flowers grow in groups at the top of straight stalks that hold the cluster of blooms up above the leaves. Some varieties have exceptionally scented flowers or blooms with quite an elegant appearance. Hostas tend to bloom in midsummer.

Introduction to hosta flowers

Hosta flowers are purple or white blossoms that grow in groups at the top of tall flower stalks. The cluster of flowers is called the “raceme.” The cluster can be dense, or the flowers can be spaced out along the stem (called a “scape”). Each individual hosta flower lasts for one day (rather like a daylily). The flowers of certain cultivars are fragrant.

Most hostas have pale purple flowers. Some types of hostas have white flowers, like Hosta plantaginea. Others have dark purple flowers or lavender flowers with dark purple stripes. Hosta plants tend to bloom in mid to late summer (July is common in temperate climates).

Hosta flowers have both ovaries and stamen (male and female organs). The flowers can be pollinated by insects carrying pollen from one plant’s flower to the stigma of a different hosta plant’s flower. Fertilized ovaries of the flowers can produce pods of seeds, which take about six weeks to grow on the scape after pollination occurs.

Tips for growing hosta flowers

Now that you know a bit more about hosta flowers, here are some tips on how to grow them in your garden.

1. Plant hostas in well-drained soil in a location that gets partial sun in the morning (unless the variety is not at all sun-tolerant). A bit of direct morning sun boosts photosynthesis and helps the plant store energy needed for its blooms. Here are more tips about planting hostas.

2. Water hostas regularly during the growing season, especially if they are grown in containers. Hostas thrive with 1.5 inches of water each week, which is more than most climates naturally offer.

3. Fertilize hostas with a balanced hosta fertilizer in early spring and again in mid-summer. Here are some tips about feeding hostas.

4. Deadhead hosta flowers as they fade to keep the plant looking tidy and to prevent seed pods from forming. Pods can be unsightly and also zap the plant’s energy that could be used for next year’s flowers.

With these tips, you should be well on your way to growing hosta flowers in your garden!
