Been buying these for 3 years now and never disappointed.
They work best for me as accent plants as fillers, like baby's breath.
Despite their delicate appearance they are tough plants and hold up very well to low water levels.
Mine have never come close to 24" tall but they mound well, play nicely with others in the pot and maintain great shape and structure.
It is a very unique plant that I have grown to love.
Highly recommend but looks best potted with at least 2 other plants.
