Hybrid orchids are the result of an experienced grower controlling the breeding of two orchids that result in a hybrid orchid with traits from both parent orchids. These traits can include determining the overall size of the new orchid, appearance of the bloom, and growing conditions. Hybrid orchids are generally easier to care for. Hybrid orchids might also include more dramatic and longer lasting blooms.

Clowesia warczewitzii × Clowesia rosea
Clowesia Grace Dunn is a primary clowesia hybrid between warscewiczii and rosea, it is one of the most successful clowesia hybrid as it is extremely prolific, flowers are produced en mass and often covered the entire plant. Flowering during leafless seasons so it always make a spectacular display.
Similar to other catasetaines, Clowesia goes through dormancy in the winter and treatment is the same as other catasetinaes.
Clowesia Grace Dunn × Clowesia rosea
Clowesia Rebecca Northen W.W.G.Moir 1971 - registered (RHS)
Rebecca Northen (Grace Dunn x rosea) is a great parent, with its 'Lemon Pledge furniture polish' fragrance and many pink frilly-lipped flowers. This is a small-growing plant that reaches specimen size quickly and has been used in many successful hybrids. Grow in medium light, water as the potting mix approaches dryness during flowering and growth period. The leaves will completely fall off either before or during flowering. After leaf drop, keep the potting mix drier and water only if the pseudobulbs shrivel. No fertilizer is required during the dormant winter season.

Made by our friend Mark Margolis, I believe this is a particularly insightful hybrid. There are only a few hybrids of this type that combine Clowesias with different bloom seasons. Here the winter blooming Clowesia Grace Dunn is crossed with the early summer blooming species Clowesia dodsoniana. The flower longevity of Clowesia blooms is generally 3-5 weeks, and this is an important reason we like to use them in breeding. Grace Dunn (warczewitzii x rosea) blooms from leafless bulbs in mid-winter and carries 15+ solid pink and green lemon-scented flowers with cute frilly lips on 3-4 pendulous inflorescences. Cl. dodsoniana has light green flowers with darker green stripes and a bit of lavender suffusion on the petals. Blooms are produced in early summer, and it is common for plants to produce two inflorescences with 30 or more highly fragrant blooms! The $64 dollar question is: “will these bloom in summer and again in the early winter?” I sure hope the answer is, yes! Picture this: multiple cascading inflorescences of 20 or more, fragrant, long-lived, green flowers with green stripes in the summer and again in the winter!!!
