Positive LysmachiaMoon On Mar 27, 2012, LysmachiaMoon from Waynesboro, PA (Zone 6a) wrote:

Does well in fairly dry shade, but needs supplemental water during very dry weather. Tough little beauty; looks great with taller, more refined plants like hosta, iris. I really like this plant; it is a vigorous spreader though and not for very small areas. It is, however, easy to control and shallow rooted. Good on rocky banks provided there's enough soil/moisture. Very dainty pale ivory tubular flowers appear in early/mid spring in Zone 6; nice contrast to the plant's coarse dark green leaves.

Can spread quickly - especially in moist areas.

Neutral Baa On May 16, 2002, Baa wrote:

Medium sized hebaceous perennial from Turkey and Asia Minor.

Has ovate or lance shaped, mid-green, bristly leaves upto 10 inches long. Bears cymes of very pale yellow, tubular, pendulous flowers. The buds are pinkish-red and some cultivars have light blue bands at the base of the flower. The whole cyme starts off curled like a scorpian's tail.

Flowers April-June

Loves moist but well-drained soils in sun or partial shade. Like all Symphytum, it can be very invasive in the right conditions.
