Chitalpa is a hardy flowering accent tree. These interesting intergeneric hybrids are a cross between Catalpa bignonioides x Chilopsis linearis almost 60 years ago in Uzbekistan. The cross created cold hardy, small flowering multi-trunked trees well suited for dry upland mid to high desert landscapes. Open irregular shaped with long green lanceolate leaves much wider than our native desert willows. Chitalpa require more regular and deep watering in the low desert to be happy.If you can site them where they only get morning sun with afternoon shade they are much happier trees as their more open spread could leave them open vulnerable to sun scald.
