SPATULATA (antelope-type) - Evergreen for several years. Most are large, vigorous plants with long-lasting blooms in
summer to several times a year.Species: antennatum, canaliculatum, discolor, gouldii, johannis, lineale (veratrifolium),
stratiotes, strebloceras, taunnum.CULTURE: Warm all year (55 to 60 degrees F nights, 65 to 90 degrees F days); no rest
period; can be kept cooler in winter if dry; medium to high light.
DENDROBIUM Most plants pendulous, leaves all along canes. Flowers 2-5 per inflorescence, from upper nodes of
leafless canes.Species - Group 1: chrysanthum, friedricksianum, nobile, wardianum.Species - Group 2: anosmum,
crassinode, falconeri, fimbriatum, findlayanum, heterocarpum (aureum), loddigesii, moniliforme, parishii, primulinum,
transparens.CULTURE - Group 1: Growth period in summer - give warmth, water, and fertilize heavily from when roots
appear until top leaf appears on canes. Then give higf light, little to no water, no fertlizer, cool nights (40 to 50 degrees F).
In other words, forget about them!CULTURE - Group 2: Same as Group 1, but winter nights 55 degrees F. Deciduous
species need virtually no water in winter.
LATOURIA Leaves at top of pseudobulbs are large and leathery, inflorescence erect, flowers commonly yellow-green.
Species: atroviolaceum, macrophyllum, spectabile, etc. CULTURE: Same as antelope-types, but cooler and drier when
resting in winter.
FORMOSAE Cane-like pseudobulbs, with black hairs on leaf sheaths and pseudobulbs often apparent. Flowers usually
white, up to 4" across, 2 to 3 together from near the end of the pseudobulb. Species: bellatulum, dearii, draconis, formosum,
infundibulum, lowii, lyonii, margaritaceum, sanderae, schuetzii. CULTURE: Intermediate to cool year-round 50 to 60 degrees
F nights, max. 85 degrees F days. Water and fertilize when growing; give a slight short rest (dry) when growth is completed.
Keep barely moist until growth starts again.
PHALAENANTHE Evergreen for several years, with thin, tall pseudobulbs, terminal inflorescences, usually appearing in
fall or twice a year (see culture).Species: affine, bigibbum (phalaenopsis), dicuphum, williamsianum.CULTURE: Grow warm
year-round (see below); 60 degrees F nights; water and fertilize heavily when roots appear from new growth; low to medium
light; reduce water and fertilizer after growth finishes. If a short (3 to 4week) cooler (55 degrees F), dry rest is given, and
then plants are warmed again (60 degrees F min.), another growth may mature during winter and bloom in spring. Treat this
growth as a summer growth cycle. These grow well with phalaenopsis, except for the rest period. If you must keep plants
cool in winter, keep them bone dry until weather warms, then water as growth appears. Plants will go deciduous with this
cool/dry treatment.
