Hoya curtisii

This charming Hoya has mottled leaves that only grow to about half an inch.  It can be grown as a house plant if your humidity is relatively high, and should be allowed to dry out between waterings.  It likes good light, either in a south or east-facing window or under strong lights in a terrarium.  It is a good candidate for planting up high in a terrarium where humidity is lower and it dries out a bit between mistings.  It is native to the Philippines, Malaysia, and Thailand.  Flowers are pale yellow and have a wonderful fragrance.
