As they bloom later in summer, slender floral stalks of Hosta might be more prominent as cut flowers than in gardens. The white or lavender flowers hang in loose clusters, so are more visible if elevated in vases rather than hovering just over their low foliage. Besides, their foliage seems to be more lush without them. Flowers are about an inch or two long.
Lush and colorful, albeit deciduous foliage is really the primary allure of Hosta. In cooler and more humid climates, the biggest plants may get more than three feet tall and nearly twice as broad! In local arid or semiarid climates, the more popular cultivars get no wider than about two or three feet. Of course, all growth dies back to the ground through winter.
The big and broad leaves are remarkably variable among the many cultivars. A few have wavy margins. Most are round, but some are notably narrow. Variegation may be yellow, chartreuse or white. Some cultivars have bluish glaucous foliage. Hosta require frequent watering and partial shade to avoid desiccation. They are vulnerable to snails and slugs, and can roast in arid and warm weather.
