Botanical Names for Hostas
Gardeners choose hosta plants for shady areas of the garden because these plants can thrive with very little exposure to sunlight. In fact, hostas exposed to excessive amounts of sunlight suffer from scorching and leaf discoloration. Propagated from rhizomes, hosta plants thrive in well-drained soils. Divide the rhizomes every few years to increase the number of hosta plants. Like most plants, hostas possess both common and botanical names. Differentiate between the diverse varieties of hosta plants by identifying them according to their botanical names.
