Two kinds of Coelogyne

Top, Coelogyne pandurata. Btm, Coelogyne mayeriana. Both species are fragrant, currenty blooming in my garden.

Speaking from experience, C. mayeriana is surprisingly easy; flowers with every new growth and easily propagated from cuttings of at least three pseudobulbs.

C. pandurata is slightly more demanding, doesn't flower as easily as mayeriana and needs plenty of space as it can grow to a very large size.
