Common Name Harrison's Bifrenaria [Mrs. Arnold Harrison, English Orchid Enthusaist 1800's]

Flower Size 3" [7.5 cm]

Found in coastal Brazil as a medium sized, warm growing epiphyte or occasional lithophyte in full sun found at 200 to 700 meters with broadly ovoid-pyriform, angled, deeply sulcate pseudobulbs carrying a single, apical, elliptic-oblong, suberect, subacute or obtuse, thin-textured, plicate leaf that blooms in the early summer on a short, basal, racemose, semi-erect, shorter than the leaves, bracteate inflorescence carrying up to 2 fragrant fruity scented flowers arising on the most recent pseudobulb often with two inflorescence on each.

This orchid grows warm and needs a dry winter rest after which, one should resume watering and fertilizer as the new growth appears in the spring.
