C. walkeriana (x sib)
('Estrela da Colina' HCC/AOS x 'Dayane Wenzel' HCC/AOS)
Native to Brazil, Cattleya walkeriana is a very compact species that may only reach 6-8" in height at maturity. The large flowers, however, can reach 4" or more in natural spread, and are sweetly fragrant as well. C. walkeriana shares an interesting trait with C. nobilior - the flowers are almost always produced at the top of a leafless growth which, after blooming, looks like a small aborted pseudobulb. In the case of walkeriana, there may be a small fleshy leaf on the flowering growth that persists after blooming. The next new growth then arises from the base of this blooming growth. Because of this rambling habit, walkeriana is particularly well-suited to a hanging basket or a mount. If it must be grown in a pot, a coarse medium must be used to compensate for the larger pots required to contain the growths. C. walkeriana generally blooms in late winter to early spring, but may bloom again in the fall with good culture.
It always seems that a great deal of controversy follows this species, with certain select (and awarded) cultivars including the alba 'Pendentive' AM/AOS and the semi-alba 'Kenny' AM-FCC/AOS suspected of not being true Cattleya walkeriana. 'Pendentive' reportedly arose from a selfing of the famous alba cultivar 'Orchidglade', and there is some speculation that these cultivars are really Cattleya x dolosa, the natural hybrid between walkeriana and loddigesii. The highly-regarded cultivars 'Estrela da Colina' and 'Dayane Wenzel' reportedly arose from a cross between 'Orchidglade' (or a selfing) and a select lavender cultivar.
