My most recent ridiculous plant purchase is this little coffee plant (Coffea arabica) I scored at HD in a 4 inch pot for 4 bucks. Kemistry has told me that they are supposed to have fragrant flowers at night. I've also read this in 'The Essence of Paradise' that coffee's scent is intensely floral and evocative. Hopefully I'll find out this summer (if it takes a while for a plant to flower I'll probably get rid of it).
All the plants looked pretty ratty with brown leaf tips but I figured I couldn't beat the price.
Just another fix to keep the fragrance addiction going through winter. ;)
