SchomburgkiasThe Schomburgkias are a New World genus of the Cattleya Alliance, classified into two subgenera: Myrmecophila,
which means ant-loving (in nature, ants are
often found living inside of their hollow
“cow horn” pseudobulbs), and Schomburgkia,
the solid bulb types. Both groups are
characterized by various degrees of tall, thin
bulbs with long (two to ten-foot) flower
spikes with clusters of any number up to as
many as fifty flowers toward the end.
Flowers occur in a range of colors from lavender-
purples to white to yellow-browns and
salmon-oranges; sepals and petals are typically
undulated. Schomburgkia species have
also been hybridized with many of the related
genera of the Cattleya alliance, contributing
great size and distinction.
TemperatureSchomburgkias are some of the largest growing orchids, with
the tallest inflorescences, demanding
ample space and high light in a greenhouse or garden setting. Here at SBOE, any that can withstand our 10-year low(minimum winter temperature of
27F for a few hours) are grown outside. Schom. superbiens,
Schom. sawyeri and many of the hybrids are known to withstand a few degrees of frost and up to 100F, thus thrive in the temperate 40’s to 80’s typical of our subtropical climate. Most species, however, need warm, bright cattleya conditions and cannot take the winter
outdoors. Our indoor greenhouse temperatures
average in the 60’s and 70’s with extremes of 50
to 100F.
FertilizerWe recommend a balanced formula such as Dyna
Gro 7-9-5 or 7-7-7 mixed regularly with
waterings.
PottingSchomburgkias bloom best as large, specimen
plants; most types flourish either mounted on
cork slabs or potted in a medium to coarse,
well-draining medium; many thrive in rock. In
most cases, after blooming-size divisions are
established, we do little to repot them; rather, we
leave them to grow over the edges of their pots
or hanging baskets, often setting them into
successively larger, empty pots to provide
support, without additional medium. The roots
take to the air-space between pots, without worry
of deterioration due to over-potting or old mix.
Also, plants naturalize beautifully on greenhouse
structures and trees outdoors.
