Anna, Your plants are beautiful. I have a great collection, but they either haven't bloomed or bloom very sporadically. I was much better about feeding them last year, but they overwinter in an old aviary and have very little light during the winter. The plants are healthy, but without the light, they don't set buds much. I have 1 bud right now and it is on an ackermanii that hangs directly under the light all winter. I would love to see 1 of mine covered in blooms like yours.
