This wonderful blue bloom is on my thunbergia erecta, better known as King's Mantle. This plant is in the same family as the Scrambling Sky flower and looks very similar. The main difference is that it grows on an upright bush rather than a vine. It's not very hardy and may not come back even in Louisiana without lots of protection. It makes a gorgeous plant for a semi-tropical garden and I really like it. I got mine at a sale at the LSU Arboretum last fall, so it cost me very little.
