Can adapt to a variety of soil conditions, but intolerant of drought. The foliage tends to decline considerably in dry conditions. Plants may die to the ground in harsh winters. Bloom occurs on new wood, so plants may be pruned back close to the ground in late winter to revitalize and to encourage vigorous stem growth and best form. If not pruned back, any weakened and/or damaged stems should be removed in early spring.
