Three-leaf sumac (
Rhus trilobata) has made many appearances on Casa Coniglio. In fact, my very
first post was about this plant. Why not? It is a beautiful native shrub that does well with no irrigation (once established). It is rabbit-proof (which is very important here at Casa Coniglio). I have a few gripes about it though.
It does have stinky sap, which while not particularly unpleasant, is
very strong, and clings to anything. Fortunately I only come into
contact with it when I am pruning.
Its size seems a bit unpredictable. The books I have read says that it is 3-5 feet tall and wide, but in my yard, it seems to be 5-7 feet tall and wants to be about 8-10 feet wide. Those growing in the wild seem quite variable in size.
It also doesn't look good pruned, and after pruning, usually produces long unbranching water sprouts that look rather ungainly.
I think of the three-leaf sumac as like the maple on the east coast. It is found everywhere here in the foothills, and the fall leaves turn a variety of colors. Maple trees also don't look good when pruned too much.
The leaves turn a variety of colors, not only between different plants, but on the same plant, and even in the same leaf. Some of this variation can be due to sun exposure.
The overall effect is some range of orange, but the leaves can turn anywhere from yellow to red.
The leaves can also range from flat to cupped, from fuzzy to shiny (almost looking like poison oak), from a half inch in diameter to several inches. Those in the nurseries tend to be yellow to orange with large flat smooth leaves. If you want a particular type, you'll have to take cuttings. Don't forget to get permission from the owner, and don't take cuttings from National Forest - it's illegal.
