That is the trouble with this BOTD, David. I always see new plants on it that I just want so much. Plant lust! LOL I can tell by your garden that you are also an adventuresome gardener and like me, will want all the different beauties! To see such beauty everyday is such a thrill.
Gee David, it may be hard to find it. I just looked on Flickr to see if I could find a lead for you and there are hardly any photos posted of it. The main ones posted are from pongsak too. Small world. LOL
