Cattleya harrisoniana

Native to Espirito Santo, state of Brazil. Cool-to-warm tolerant, with a preference for intermediate to warm growing conditions. Medium-light, summer-to-fall bloom season. Produces lightly fragrant flowers that last longer than standard Cattleya.

The last photo is the example of the size you will receive. Current plants are recent divisions in sphagnum moss which have buds that should open by mid July.
