Title: Comments on non-native Tecomas from Phoenix AZ
Answered by: Barbara Medford
We are not a forum, which explains why you cannot reply directly. Instead, Mr. Smarty Plants answer questions having to do with plants native not only to North America but to the area in which those plants grow natively. If you will recall, the original answer was:
"I suspect that the red esperanza you are seeing isn't a Tecoma stans (Yellow bells or esperanza) at all, but another species, a close relative called Tecoma capensis (cape honesuckle), an introduced species from South Africa. Here are more photos of Tecoma capensis.
Another possibility is Tecoma fulva, a native of South America.
I couldn't find any varieties of Tecoma stans that were red, however. I did find some hybrid varieties that were yellow with red highlights giving them an overall orange color. Here are a couple of those:
Any time a plant name has an "x" in it, it is hybridized. Many of the plants sold in nurseries that are taken as Tecoma stans are either tropicals or have been hybridized with tropicals, and will not do well in areas that get frosts. Two of the plants mentioned in the original answer are definitely tropical non-natives, and as native plant proponents, we would not recommend them. The original question came from San Antonio, which had some "surprise" freezes last winter and lost plants they thought were native and hardy to where they lived.
