After a while everyone sort of
hits the wall with the number of plants that we can comfortably handle and
want to switch to some miniatures. We often have customers come in and ask
the question "what greenhouse are the miniatures in?" The answer is there
are miniatures in every greenhouse. The next question is are they hard
to grow. No pat answer to that question but there are a few that are
difficult, and most need a little more attention than your larger plants.
Below is a summary the cultural requirements of the species pictured above.
Acronia sanchoi is a miniature sized, warm growing
epiphyte found from Guatemala, Costa Rica and Panama. It blooms in
late spring through late winter on a short inflorescence with 1 or 2
simultaneously opening flowers held close to the leaf base.
Intermediate light, and high humidity.
Pleurothallis corniculata is a
miniature, hot growing epiphyte found in Mexico, Guatemala, Nicaragua,
Panama, Cuba and Jamaica in dense tropical forests. It blooms in cultivation
successively in the spring with few, single flowered
inflorescence.
Pleurothallis alata is a micro-miniature sized, hot to warm
growing epiphyte found as a in Mexico, Guatemala, Honduras, Nicaragua and
Costa Rica. It blooms in the fall on an erect, successively single
flowered, filiform inflorescence that is much longer than the leaf.
Lepanthopsis astrophora this
miniature sized, hot to cool growing, epiphytic species is found on coastal
Venezuela and Colombia. It blooms in the fall and spring on a terminal,
erect, many flowered, inflorescence arising from the apex of the
ramicaul with up to 6 flowers that open simultaneously and are held well
above the leaves.
Bulbophyllum tingabarinum miniature
sized, warm to hot growing epiphyte is found in Laos, Vietnam and Cambodia
with a tetragonal, pseudobulbs carrying a single, apical, elliptical leaf
that blooms in the fall and winter.
Ondicium edwallii a small, warm to cool growing epiphytic
species found in the Serra do Mar of Sao Paulo State Brazil in hot humid
lowlands of the coast and interior marshlands has rounded, sharply laterally
compressed, psuedobulbs. It blooms in the spring with a few to many flowered
inflorescence arising on a newly matured pseudobulb.
Angraecum distichum this miniature to
small sized, hot and humid growing, Lockhartia-like epiphyte is found
in many regions in Africa growing on large trees in rain forests. Mature
plants form large clumps and blooms on a very short, solitary flowered
inflorescence with a long-lived, small, fragrant flower occuring at any time
of the year on new leaves and most often more than one.
Aerangis luteo-alba v. rhodostichta This miniature to small
sized, epiphytic species is found in the Central African Republic, Cameroon,
Congo, Zaire, Ethiopia, Kenya, Tanzania and Uganda in forests on small
twigs and branches of bushes and trees, rarely on trunks. They can bloom in
the winter or spring and they have fragrant flowers in two flat rows, on an
arching or pendulous inflorescence with small floral bracts. In the summer
the plant is in full growth and they need high humidity and plenty of water
and fertilizer until mid autumn when it should be reduced, but not to the
point of being dry.
Dendrobium laevifolium a mini-miniature, warm to hot growing
epiphyte that occurs on moss covered trees in the South West Pacific. It
blooms on a very short, 1 to few flowered inflorescence that arise
from the nodes at the apex of the leafless stems and occurring in the
summer. Slightly reduce water and withhold fertilizer until new growth is
initiated in the spring.
Dendrobium reflexitepalum a medium
sized, hot to warm growing epiphyte found in Java and Sumatra. The stems
erect in youth becoming pendulous with age blooms in the fall, winter and
early spring on young stems from the tip. and on older plants from along the
leafless apical portion with a single flowered, short inflorescence.
Restrepia brachypus and
Restrepia striata a miniature sized, cool to cold growing epiphyte found in Venezuela, Peru, Ecuador,
Bolivia and Colombia in wet montane forests. They prefer lower
light and high humidity. They flower almost anytime but mostly in
winter and spring on threadlike, single flowered inflorescence. Can be
grown mounted or in pots.
Restrepia xanthophthalma a miniature
sized, warm to cool growing epiphyte found in Mexico, Guatemala, El Salvador, Honduras, Nicaragua, Costa Rica,
Panama and Colombia to Peru in wet montane forests. Again low light is
preferred and high humidity. Can be grown mounted or in pots. Blooms
anytime during the year.
Scaphosepalum anchoriferun
a warm to cool growing
epiphyte found in Costa Rica and Panama in premontane and lower montane
rainforests. They bloom in late summer to early fall, preferring low
light and high humidity.
Maxillaria uncata small,
temperature tolerant, creeping epiphyte, found in French Guiana, Surinam,
Guyana, Venezuela, Colombia, Ecuador Peru and Brazil in wet montane
rainforests. They bloom through the late spring, summer, fall and winter
months on a single flowered inflorescence. They can be grown either
mounted or in a fine mix in semi-shade and constant year round
conditions.
I encourage you to checkout our upcoming events page, for the activities at
Parkside now through the end of the year. We already have had two classes
one on Growing Orchids in the Home and a second on Repotting Orchids. I
would especially like to bring your attention to the all day Symposium on
November 12. This day will include several talks and of course a very
special Parkside style lunch.
