so i recently got a 'full sized' psychopis, a mendenhall 'monarch' and yeah, this is a dwarf variety right here. the plant is a bit smaller, the flowers are roughly half the size and substance of the big one. and the stems are shorter by half too. a tidy little thing in comparison. stays more compact and less gangling stems. if it dries out, the stems stop growing and don't flower. must keep it moist!
