Welcome to the Clowesetum

 

The American Orchid Society recognizes the Clowesetum as an inter-genetic hybrid-cross of the Catasetum and the Clowesia    (https://catasetinaecanada.weebly.com)

 

This group of orchids is again an interesting breeding combination producing multiple flowers, vigorous growth and the possibility of flowering two to three times a year. Typically, their now trigger-less flowers have a flower life that is longer than the pure Catasetums.  Clowesetum are heavy feeders during their growing period but a dry rest period of differing lengths according to species is needed after flowering, specifically, once the plants start to drop leaves. Water is gradually reduced, then withheld. If at all, water sparingly only to prevent pseudobulbs from shrinking too much. Once new growth reaches 4 inches and new roots reach 2 or more inches long, watering is resumed, with normal abundant watering taking place once the potting mix again approaches dryness. Fertilize well during the active growing season as the plant does not get a chance to be fertilized during its dry rest period. Clowesetum like humidity of 50-70% with warm day temperatures of 75-80 F (24-27 C) dropping 10-15 F (6-8 C) at night. Repot just as new growth is beginning at the end of the dry rest.  (https://catasetinaecanada.weebly.com)

(Clowesia Grace Dunn 'Live Oak' HCC/AOS x Catasetum tigrinum 'SVO')

 

This year we're trying some mini-Clowesetums.  The hybrid genus Clowesetum (Catasetum x Clowesia) is known for flower longevity and multiple simultaneous inflorescences.  Grace Dunn (warczewitzii x rosea) produces 15+ pink and green flowers with cute frilly lips on 3-4 pendulous inflorescences from leafless bulbs in mid-winter.   Ctsm. tigrinum is a very special species: small-growing, and flowering several times a season with cascading inflorescences that each hold 15-30 white-cream blooms spotted lightly in red on the petals and sepals.  Equally important are the shape and placement of its wide petals, which fill the space between the dorsal and lateral sepals, creating a full-shaped flower.  This is a great characteristic, which is transmitted to its offspring and very valuable in hybridization.  This mini-Clowesetum will flower at 4-6” tall and bear cascading inflorescences of flowers with excellent shape in pink, white and cream.  The long-lived flowers will be produced in fall and winter.  This promises to be a very charming hybrid!
