Gardeners' Notes:

Positive aguy1947 On Aug 23, 2006, aguy1947 from Portugal Cove-St. Philip's, NL (Zone 5a) wrote:

I have several plants grown from seed. Also, I have seen a plant growing / blooming in a friend's garden. The most noticeable characteristic is the arching or angled stems from which the bells hang. The angle is about 45 degrees from the vertical. Comparing /contrasting this one to the C. ochroleuca (also grown from seed), the stems of C. ochroleuca here are straight up, with the bells upward/outward facing. Both are admirable garden plants.

Ivory bells form an 18-inch clump of heart shaped leaves. Its erect leafy stems produce nodding, 2-inch creamy-white bells from midsummer to early autumn. It prefers a moist well-drained soil in sun or partial shade
