A TRIAD OF NEW HOSTAS FOR SHADE WITH 3 MAPLES TO AVOID




Monticello in Winter
Greetings from Charlottesville, Virginia!




"No occupation is so delightful to me as the culture of the earth,
no culture comparable to that of the garden ...
But though an old man, I am but a young gardener."


Thomas Jefferson, Garden Book, 1811











The Green Man wishes all a Happy New Year 2010. And, a new year means making preparations for Spring gardening and landscaping!

Many clients seem frustrated by shady areas on the grounds. Often older, established sites are planted with enormous maples that create dense shade. While most these trees are fine in the proper location, too often they end up having been sited too near the house itself.

Sugar maple (Acer saccharum) is often the "culprit." It's a fine tree for the edges of the property where it has room and shade may not be an issue. Much worse is Acer saccharinum or Silver maple...fortunately, these days usually unavailable because of its weak-wooded structure and rapid, weedy growth. Finally, the worst offender is Norway maple (Acer platinoides) and its cultivar ("cultivated variety") 'Crimson King.' The latter was planted extensively to provide the color burgundy in the landscape. The problem is that it is an introduced species that proliferates and drives out desirable native species. However, because of its enormous, leathery leaves, this tree casts dense shade. Do not use it!

Hence, a good rule of thumb is to plant no maples AT ALL with the exception of these 2 varieties that are smaller and add value to your property: Japanese maple (Acer palmatum) and paperbark maple (Acer griseum.)

Japanese maple 'Fireglow'



Paperbark maple provides Winter interest with its cinnamon-colored exfoliating bark

The Green Man recommends 'Fire Glow' for the former and the use of 1 or 3, not 2, paperbark maples towards the back and side window areas of the site. These 2 maples are highly desirable trees and readily available at quality nurseries and garden centers. If you want a compact draping Japanese maple as a focal point tree near the house entrance, use 'Crimson Queen.' Thousands of Japanese maple cultivars exist, but keep it simple for starters.

Meanwhile, if your site is shady, do not despair! You simply have a "woodland garden" site, so work from there. Make any full-sun locations burst with color, and then work with a much more subtle color palette for the woodland garden areas.



Glorious Solomon's seal in bloom

Begin with the basic The Green Man woodland garden triad: Hostas, ferns, and Solomon's seal, and accent with a few woodland garden specimens such as astilbe in tight groupings. Use WHITE astilbe and BURGUNDY astible only.



Use Astile 'Vision in Red' and white Astilbe only, or the woodland effect will be destroyed.

Every other color tends to overpower the impact of adjacent plants with hideous, muddy shades of pink and worst of all magenta, a garden no no.

OK, here are three relatively new hostas for 2010 that can be incorporated into your woodland garden setting. Note that none features YELLOW. Do not use YELLOW hostas as they compete for attention. Use WHITE as much as possible to brighten shade along with lush greens. Use blue hostas carefully as they create focal areas and can grow huge. A single specimen of blue is best.

Create lozenge rather than circular beds 6' across widthwise at the bases of your shade trees. Cover exposed roots first with a small berm of soil...with the soil kept away from the tree trunk base.

White periwinkle, 'Vinca minor alba'

The ideal shade groundcover is Vinca minor alba or white periwinkle. Do NOT use the common blue.





Use trouble-free daylily 'Happy Returns' in PRIMARY YELLOW in any shade areas that receive some sunlight. You will get a remarkable number of flowers and the leaves provide texture, height, and complementary interest.



Stalwart daylily 'Happy Returns' in primary yellow






DO NOT use 'Stella d'Oro' daylilies ever as the chome yellow will throw off the color scheme, and it is an over-planted variety best saved for its KFC and Taco Bell sites.






















Hosta 'Dancing Stars' PPAF

NEW Incredible thick leaves that holds the crisp colors better than any similar types.

A Burpee Exclusive of a hosta that thrives in the shady garden with incredible thick leaves that holds the crisp colors of the white center with dark blue-green margins better than any similar types.

Hosta 'Silver Bay'

NEW Spectacular blue color. Thick leaves with a striped pattern.

A fantastic silver-blue mounding hosta with thick leaves with a striped pattern likened to seer suckering. The intensity of the blue color is spectacular, will stand out in every garden where the primary color is green. Use as an edging, border plant due to its well-mannered short growth habit.

Hosta 'Night Before Christmas'

Hosta Night Before Christmas dark green leaves with a central white splash, pointed and slightly twisted leaves. Large mound size at maturity.

Not 'brand new' per se but 'new' as it's woefully underused.
