Thanks to Tony Avent for the ID on this plant. It was distributed by Ellen Hornig as ascyrifolium, but she was never positive on the i.d. It’s tough as nails, clump forming, incredibly long blooming and versatile, growing and flowering from deep shade to sun, and very well behaved (non-seeding). Starry white flowers on terminal ends, beginning in mid spring, on stems upright to lax, depending on light exposure. It’s one drawback is the length of time required to get a plant to salable size, hence the price. 12”x18”, Z5, Quart pot.
