Hosta by far is the most popular and well-known shade plant in the United States. Many thousands of cultivars exist from original species native to China, Japan, and other forested areas in Asia. Hosta foliage arrises from a clump-forming root system and is often large and dramatic with many types of variegation. Flowers, born on tall stocks ranging in shades of white and purple, are equally attractive. Hostas grow best in rich, well-drained soils in full to partial shade. In Eastern Kansas with our average 40 inches of average rainfall, plants are drought tolerant if established in moisture-retentive high-quality soil. Dry-shade areas are best avoided. Afternoon sun with temperatures over 95 degrees F but likely burn the tips of hosta foliage rendering them unattractive for the rest of the year. There is no secondary growth by late summer after flowering and after buds have been set for next year. In northern parts of the country, hostas can handle full sun. In the Southern part of their range further South than zone 7, hosta can really struggle through the long summer heat unless conditions are perfect. Rabbits, deer, slugs, and snails can be a problem generally on small or un-established plants. Large-leaf robust varieties seem to outgrow browsing predators better than small dainty varieties. Methods of control are effective ranging from cages to deer repellents. Generally, a large established planting of hostas will be there for decades gradually getting thicker and denser without a need to divide. Many plantings have been in our display garden for 15-20 years with no weeds ever trying to grow in the shade of the foliage. Hosta foliage is susceptible to late spring freezes so try to cover if possible. During the Easter freeze of April, 2007, thousands of hosta were killed to the ground in eastern Kansas but all returned successfully by May from secondary buds. Hosta's newly unfurling foliage is considered edible when cooked like asparagus or eaten raw in salads. Hosta 'Bulletproof' has extremely thick blue leaves that look good all season: very resistant to slugs and snails. Sport of 'Halcyon'
