Genus Hosta (Plantain lily)

HOSS-tah Common Name: Plantain lily
Roughly 70 species make up this genus of mostly clumping perennials from China, Korea, Japan, and Russia. Hundreds of cultivars are available. They are grown for their bold foliage which may be variegated or shades of green, yellow, or grayish blue. Variegation may be wide-margined, narrow-margined, or centrally marked. Leaves can be ovate, lance-shaped, rounded, or heart-shaped. Flowers are borne in racemes, mainly in summer. Hostas can be used as accent plants, as groundcovers (even under some trees), in beds and borders, at waterside, or in rock gardens.  
Noteworthy characteristics: Ornamental, bold foliage. Very hardy. Somewhat drought-tolerant.
Care: Hostas grow best in Zones 3-9. They need fertile, moist but well drained soil. They can tolerate shade, but perform best with full morning sun in northern areas and filtered shade in the south.
Propagation: Sow seed in a cold frame in spring, using containers. Divide in late summer or early spring.
Problems: Slugs and snails are common problems. Viruses and foliar nematodes can also affect hostas, and container-grown plants are vulnerable to vine weevil.

This hosta looks almost good enough to eat. A profusion of shiny, avocado green foliage with darker green margins forms large, dense clumps. ‘Guacamole’ does best in partial shade, where the sun can brighten the richly veined leaf centers. In late summer, the cooking really heats up as 3-foot-tall flower stalks emerge, sporting a plethora of sweetly fragrant, lilylike white blooms.

Hostas are the first plants to come to mind when shade tolerance is required, but not all of them can take the heat in our region. ‘Patriot’ has proven to be one of the toughest, and its white margins and relatively large leaves make it a beacon of brightness in the shade. As a bonus, it will flower in midsummer with lavender trumpets on tall spikes.

‘Halycon’ is a wonderful blue hosta. Unlike some others, ‘Halcyon’ retains its strong leaf color all season. Its textured, blue-green leaves are thick enough to be slug resistant. The bell-shaped, pale lilac-blue flowers are attractive, and the resulting seed heads are visited by birds late in the season. This cultivar is fairly slow growing but can be used as a ground cover as well as a specimen.

One of the largest hostas available, ‘Elegans’ has deep, smoky blue foliage with a slight hint of frost. The heart-shaped leaves remind me of a handheld paddle with deeply defined veins. White flowers rise above the leaves on long stems. Though slugs love hostas, this one is usually left untouched.

This early-blooming, clumping perennial has thick, round, corrugated, powder-blue leaves 8 to 10 inches long, topped by lilac-tinted white or pure white flowers rising just above the foliage in early spring.
