I have been trying to identify a plant that a friend brought to Colima, Mexico some years ago from Costa Rica. It looks like it could be a Salvia and possibly a Salvia tiliifolia, although the flower color we find on the internet is blue and the flower color of this plant is a deep reddish purple. We believe the plant is native of Central America. I know the plant has a square stem and no apparent odor (although I just have a cutting with a couple of flowers, so the mother plant may be odiferous but i don't know. It is a large bushy plant, 1 meter tall +. The flowers are small. Does anyone know this plant? also, attracts butterflies. there is a close-up of the flower on the next post. I guess we can only have one photo at a time?
