I have this Antigonon leptopus (Honolulu Creeper, Coral Vine) from the Family Polygonaceae with heart-shaped leaves planted along my corridor and it is flowering so reliably. Too bad I couldn't take photos of the leaves and pink flowers drooped over the parapet wall without risking my life!
So I took photos of this climber this morning at my resident kopitiam and wish everyone a belated but wonderful Valentine's Day. See the numerous heart-shaped leaves? Hope this year brings you all lots of love!
