Be sure not to miss the 2 houseplant greenhouses accessible from the propagating table room where you purchase your plants.  Ask a volunteer if you don’t see the entrance.  There you will find common houseplants like philodendron, pothos and small weeping ficus trees as well as colorful plants like coleus, tradescantia, large selection of bromeliads and variegated spider plants…all at unbeatable prices.  Many other varieties come and go so check back frequently!
