Flasks of Cattleya walkeriana var. alba 'Pendentive' AM/AOS × self

Culture Notes from Donor: Parent plant: Temperature range I (60-83°F)

Comments: Parent plant: Arguably one of the best walkeriana cultivars around. Temperature tolerant to a wide range. It lives up to its name by walking out of any pot it inhabits. It likes to be mounted if possible. Flowers are very nicely scented. Small plant.

Flask Information
Availability:	We have sold all of the flasks for this item.
You should:	Consider getting individual plants or compots instead of a flask. See if we have plants available in the greenhouse.
Yield Estimate:	2530 plants (based on flask surveys done 04/22/2008 through 02/02/2015) Yield estimates are only approximate, but may appear to be fairly exact numbers because they are a combination of large rough estimates in remaining mother flasks and more accurate small estimates in reflasks.
Plantlet Sizes:	From many flasks 10 - 80 mm plants (based on flask surveys done 04/23/2008 through 01/05/2016) From one most recently surveyed flask 30 - 50 mm (01/05/2016)

ORIGIN/HABITAT: Brazil. C. walkeriana is found over a large region of the interior south of the Amazon Basin, including the States of Minas Gerais, Goias, and Mato Grosso. Brasilia is just west of the center of this area of distribution, Belo Horizonte is near the southeast edge, and Goiania is near the western edge. Within this overall area of distribution, plants are usually found at 2000-3000 ft. (610-910 m), growing in two distinct types of habitat. In one type, plants are found on very rough barked trees which grow in an alkaline environment on limestone bluffs, ridges, and mesas known locally as pedreiros. While the region is very dry much of the year, the limestone of the pedreiros is able to soak up and retain large amounts of water during the rainy season. This moisture is given up very slowly as the surrounding trees respire it into the air through their leaf surfaces, providing a relatively stable source of high microclimate humidity in an otherwise dry environment. The second type environment, known locally as chapada, is in regions where the limestone was not deposited on the underlying granite. The relatively flat granite plateau has been cut by eroding streams, leaving almost perpendicular cliffs as much as 1000 ft. (300 m) tall on either side. C. walkeriana is found in this habitat where streams plunge over the edge of the cliffs. They usually grow with their roots attached to bare granite rocks near the top of the cliffs along with lithophytic cacti, succulents, and epiphyllums. Some plants are found on rough-barked trees near the edge of the cliffs, but they are never very far from streams or areas with permanent water seepages. Moisture rising from the waterfalls condenses as soon as the temperature starts to drop in the evening and quickly covers plants and rocks in the vicinity with large amounts of water, even during the dry season.
