The first of my Habenarias to bloom this Summer is Habenaria rhodocheila. Surely I will post this one a couple more times as it just starts to open.
edited to correct - this is not rhodocheila, it is Habenaria erichmichaelii and should be fragrant.
I keep this one and the Habenaria medusa during the dormant season in the Winter with the Stapeliads. They only get a gently spray into their direction once in a blue moon and I never soak them through during those times. It is now potted up in Canadian Peatmoss, and that seems to be ok for them.
