Mundane floral color and a lack of floral fragrance are no problems. Smokebush, Cotinus coggygria, compensates. Its uninteresting bloom reveals strikingly fluffy floral trusses for summer. These trusses eventually deteriorate to reveal exquisitely vibrant foliar color for autumn. This foliar color eventually deteriorates to reveal sculptural trunk form for winter.

Foliar color through spring and summer is likely the most striking attribute of smokebush. Most are boldly rich purplish bronze. Some are strikingly vivid yellowish chartreuse. The two extremes contrast splendidly. Old fashioned olive drab is now rare. Foliar color does not fade much. However, it suddenly transitions to fiery orange and red color for autumn.

Old fashioned olive drab smokebush can grow a bit more than fifteen feet high and wide. Because it does not grow fast, only old specimens are so large. Most bronze cultivars do not get much higher than first floor eaves here. Chartreuse cultivars are likely to stay a bit shorter. Healthy young specimens might get wobbly if their canopies outgrow their roots. Aggressive pruning improves form and stability, and can also enhance foliar color.
