Thunbergia alata is one well behaved little vine I can't remember not having a dozen or more snaking throughout the weed patch & another dozen climbing a wooden fence. This year for some reason there was no need to plant a single seed as the Thunbergia alata took over everywhere even the tallest banana,when the Lilly patch finished its display I let the vine have a go (lilly stalks after blooming ,well they are not attractiive) problem solved. today's Christmas day!! Where there is protection there are Thunbergia giving a last push! An attraciive easily controled versatile cloak Or a wicked Hot Mess. 4 stars from me. Mobile Al.
