Link to the variegated caricature plant. http://tom-piergrossi.squarespace.com/buy-plants-m-r/pseuderanthemum-carruthersii-var-atropurpureum-variegatum

Could you show us more details of these plants i.e. photos of the whole plant and flowers or seeds if there any? For now I could only speculating on two of them. 1- ? 2- Maybe Delonix regia ( many common names included Royal Poinciana, flamboyance tree, etc…). 3-Maybe variegated caricature plant (Pseuderanthemum atropuepureum Variegatum). Again I’m only guessing, if these are not correct; make new post with more photos. Best wishes! Link for D. regia https://keyserver.lucidcentral.org/weeds/data/media/Html/delonix_regia.htm
