Plant More Pachysandra - Paul Snyder


Flowers of Pachysandra procumbens.

Pachysandra. We should be planting more of it. Many of you reading this are repulsed by the thought of someone wanting to plant Pachysandra. And you should be. Before you close your browser I want you to know I’m talking about the good kind,Pachysandra procumbens, Allegheny Pachysandra, not the non-native species that you’re most familiar with,pachysandraterminalis, Japanese Pachysandra. Jim Chatfield mentioned Allegheny Pachysandra in aBGYL articlea couple weeks ago and inspired this article.

Pachysandra procumbensis an excellent low-growing groundcover only six to ten inches tall. The plant is native to the southeastern United States (not native to Ohio), thought it's hardy to zone 5. Allegheny Pachysandra differs from Japanese Pachysanda in that it forms clumps rather than forming impenetrable rhizomatous mats.

The leaves of the Allegheny Pachysandra emerge green in the spring and soon turn blue-green. By late summer the leaves develop white mottling, which adds to the beauty of this plant. In fallPachysandra procumbenscan turn light red or plum purple.

In early spring fragrant white flowers emerge from the center of the plant. The showy male flowers are loved by many native bees. Male flowers are borne above the female flowers, which remain close to the ground and lack showy petals. The plants are self-incompatible meaning that they require pollen from another plant in order to produce seed. For this reasonPachysandra procumbensrarely produces seed.
