 Common Name: Hosta
Common Name (Alternative): Hans Hansen

This unique blue hosta is popular among hosta collectors and makes a very nice specimen in the home garden. 

In spring, the narrow wedge-shaped leaves are bright glaucous blue and they hold their color well.  As the season progresses they turn more blue-green.  The heavily rippled leaves are of good substance, displaying some slug resistance. 

This hosta has a lovely cascading form that is displayed to best effect when planted on a ledge or in a container. 

Lavender flowers are produced on arching scapes in late summer to early fall.

Hostas are exceedingly popular perennials in today's gardens due to their versatility in the landscape. Their subtle colors, tall flower scapes, and broad, coarse leaves fill a niche in garden designs that few other plants can achieve. Their large leaves provide excellent coverage for dying bulb foliage. Hostas also grow well in city environments where the air may be polluted by car exhaust, etc.

Homeowner Growing & Maintenance Tips:

Hostas grow best in moist, well-drained, highly organic soils with a pH between 5.5 and 7.5. Sandy loam is better than clay because it provides more aeration for the roots. High-filtered or dappled sunlight is necessary for clean, healthy growth. Morning sun is tolerable and will help to intensify the leaf colors, but hot afternoon sun is usually deadly to hostas. They are most at home in shady, woodland settings and often work well as specimen or edging plants.

Especially in northern zones, hostas should be mulched with a layer of finely shredded organic material to prevent heaving in the winter. Mulch is beneficial because it retains moisture around the plant's roots, but it is also the ideal place for slugs to hide. Watch for holes in the center of the leaves. If they are present, so are slugs. Applying a slug bait in early spring when new shoots are beginning to emerge will help to reduce the slug population. After a few years when plants are firmly established, the mulch can be removed completely, which should eliminate the slug problem altogether. Also be sure to clean all hosta foliage out of the garden in early winter after the plants have gone dormant. By doing so, you will be ridding the area of the eggs of slugs and other leaf-eating insects.
