2015 Dividend Plant Selections

This year we are offering a great plant for your garden, plus many surprises from our surplus of native and exotic plants from wild-collected seed. Our featured dividend plant this year is:

Ruby Spice summersweet clethra - Clethra alnifolia ‘Ruby Spice’

Ruby Spice clethra is the darkest red of all the clethra varieties. The sweetly fragrant, bottle-brush flowers appear in late summer, attracting butterflies, bees and other insects, and in autumn the handsome, glossy green foliage turns butter yellow and rich brown. The seed capsules form an interesting display for the winter. 1998 Gold Medal Plant Award by the Pennsylvania Horticultural Society. Clethra alnifolia is native to eastern North America and is an excellent choice for use in a mixed border.

This deciduous plant prefers full sun to part shade, is very easy to grow, and tolerates a wide range of conditions. It will mature to 4 feet wide x 4-6 feet tall.

Surprise Dividends

As always, plant connoisseurs eagerly anticipate the plant sale every year to pick among the rare and unusual plants that we offer that are surplus from the greenhouse inventory. To whet your appetite, among other items, we will have common spicebush (Lindera benzoin), and an Asian jack-in-the-pulpit (Arisaema consanguineum). Please keep in mind that supplies of these are very limited so that when they’re gone, they’re gone. Come early to the members’ preview for the best selection.
