Hostas are popular perennials known for their lush foliage in shady gardens. Varieties described as “purple” are particularly sought after for their unique color, adding depth and visual interest to landscapes.
Understanding Hosta Coloration
The term “purple” in hostas mainly refers to their flowers, which range from soft lavender to deep purple. Truly purple leaves are rare; what appears purplish on foliage is usually a deep blue, especially in new growth or certain light.
Some hostas also have purplish petioles (stems connecting the leaf to the main stem) or purple flower scapes. While foliage is typically green, blue, or yellow, these elements, along with the elegant floral spikes, contribute to the plant’s overall “purple” appearance.
Top “Purple” Hosta Varieties
Many hosta cultivars are prized for their purple floral displays or other purplish characteristics. ‘Halcyon’ is a notable hosta with intense, powdery blue leaves that can appear almost purplish in certain light, complemented by light lavender flowers. Its flower scapes often exhibit a subtle purplish tint.
‘Guacamole’ is another popular choice, known for its large, apple-green leaves with gold centers that lighten in brighter light. Its fragrant, pale lavender flowers emerge on tall scapes, providing a beautiful contrast to the foliage. The blooms of ‘Francee’ are a deeper lavender-purple, appearing above its dark green leaves with crisp white margins.
‘Blue Angel’ boasts very large, corrugated blue-green leaves and produces pale lavender to purple flowers on tall scapes. ‘Praying Hands’ offers a unique upright, vase-shaped form with dark green, twisted leaves and distinctive deep lavender flowers that appear in late summer.
Growing and Caring for Purple Hostas
Successful hosta cultivation begins with proper site selection. Hostas thrive in partial to full shade, needing protection from intense afternoon sun, which can scorch leaves and diminish color. Filtered light or morning sun with afternoon shade is ideal for healthy foliage and robust flowering.
Well-draining, organically rich soil is essential for hosta growth. Incorporating compost or other organic matter before planting improves soil structure and fertility. Consistent moisture is crucial; hostas prefer evenly moist, but not waterlogged, conditions.
Light fertilization in early spring provides nutrients for vigorous development and abundant flowering. A balanced, slow-release granular fertilizer applied around the plant’s base is sufficient. Hostas are susceptible to slugs and snails, which can be managed with bait or hand-picking. Proper spacing also promotes good air circulation, reducing fungal issues.
