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)

Clowesetum Black Jade

Written by

Clowesetum Black Jade

 

This is a very floriferous hybrid influenced by the exceptional flower count of Clowesia russelliana. The flowers will be green to deep jade green, and lips will be green with a dark burgundy center. Expect many flowers on 2-foot-long pendulous inflorescences. Yes, you read it right – Two-foot- long inflorescences.  These plants will produce a memorable show of long-lasting flowers in late summer.  A spectacular hybrid.

(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!

Clowesetum White Magic

 

This hybrid was in my collection in the early 1990's. I had one plant with icy green flowers and the other with pure white blooms. I'm not sure what happened to those plants, but after all these years I haven't forgotten about them. When both parents were in flower, I had to re-make this cross.   Clowesia warczewitzii has a small, light green flower with darker green stripes. Plants bloom in early winter, and the flowers have a pleasant lemony scent. Catasetum Orchidglade (pileatum x expansum) has a large flower with a huge lip in light yellow with scattered red spots. Expect full-shaped flowers in light green to white, and a few may be spotted as well. Clowesetums have many good traits:  long flower life, multiple spiking habit, good form, and pleasant fragrance. This grex should be excellent, and there's a distinct possibility that some plants will have pure white flowers.

Unregistered Hybrid

 

( Clowesetum Abigail Parsons 'SVO' HCC/AOS x Catasetum spitzii 'SVO Solid Gold' FCC/AOS )

 

Clowesia Abigail Parsons (Clowesia Grace Dunn x Catasetum John C. Burchett) come in a range of colors. The most striking I've seen is the cultivar 'SVO,' with olive green flowers and a rose blush, all beautifully arranged on two inflorescences of 16 flowers each. Receiving an FCC/AOS indicates the high quality of a plant and its flowers. Catasetums spitzii 'SVO Solid Gold' is just such a cultivar. When it was awarded, this plant carried 23 large, solid yellow flowers perfectly arranged on a 2-foot-long inflorescence. Truly an amazing sight!  We are using spitzii in this cross for several reasons: it has a very flat, thick hard lip, that will flatten and broaden the lips of the offspring; it had a pure yellow color that will warm up the olive green and rose blush of the Abigail Parsons; and its high flower count will produce floriferous offspring.  These qualities, along with long flower life, multiple spiking habit, good form, and pleasant fragrance make this is Clowesetum a very good prospect.
