Description
Culture
Characteristics
- Hosta is a large genus that includes at least 45 species of clumping, herbaceous perennials that love shade and moist soil. When developed cultivars are included, there are hundreds of varieties available for landscape use. Some 3,000 named varieties are registered. The species are native to the woodland areas of Japan, Korea, China, and eastern Russia. Hostas are primarily known for t…
Name
- The genus name derives from Austrian botanist Nicholas Thomas Host. The genus was renamed in 1817 as Funkia in honor of botanist Heinrich Christian Funk, but the original name was restored in 1905 by the International Botanical Congress. The name funkia is still used in some areas; another common name is plantain lily, coined because the leaves resemble those of the plantain.
Usage
- Hostas are most often used in shade gardens, where the ornamental foliage brightens dim areas. Hostas work very well in groups or in masses, and they are also good as background plants or specimens in shady borders or woodland gardens. Yellow-leaves varieties are somewhat more tolerant of sun, but no hostas will thrive in perpetually hot, sunny areas.
Toxicity
- Hostas are edible and are grown as food in parts of Asia. However, they are somewhat poisonous to dogs, cats, and horses, which may exhibit vomiting if they eat the leaves or flowers.
Cultivation
- Hostas are normally planted as potted transplants. They prefer moist but well-drained soil in a shady or partial-shade location. They grow best in a location protected from strong winds. Once established, hostas will tolerate occasional dry soil, but they will not survive long periods of drought unless regularly watered. Watering is best done near ...
Varieties
- There are hundreds of varieties of hosta available for sale, and a large nursery may stock a dozen or more. Among the more popular varieties of recent years are:
Ecology
- Although very easy to grow, hostas can fall prey to slugs and snails that chew ragged holes in the leaves and can kill the plants if left untreated. Deer are also voracious feeders on hosta leaves.
Symptoms
- Foliar nematodes can cause the leaves to brown between the veins. Leaf spots and crown rot also occasionally are seen. Several viruses are known to attack hostas; when stricken, afflicted plants must be removed and destroyed.
Management
- Hail storms can severely damage hosta leaves, leading to disease problems. Affected leaves should be removed; the plant will soon recover.
