Glasshouse Works Plant Codes for Catalogue

CODES AND ABBREVIATIONS USED IN THIS CATALOGUE

In each entry after the stock number and scientific plant name, several brief codes appear:
PLANT FAMILIES--THE FIRST CLUSTER OF LETTERS
Many of our customers prefer to collect within particular plant families, and so appreciate this guide. For example, ORC indicates Orchids, Ges indicates Gesneriads, LIL would refer to the Lily family and GRA the grasses; it becomes a bit more complicated with COMP (COMPositae) indicating the daisy groups, ZIN (ZINgiberaceae) representing the ginger family, and LAB (for LABiatae) indicating the mints. AMARY indicates AMARYyllidaceae for bulb collectors; EUP is shorthand for the EUPhorbiaceae, the Euphorb or Spurge family; while POLYP stands for POLYPodiaceae, the footed fern complex. You can easily find a fascinating listing in your copy of Hortica or Exotica of these major tropical plant families with a brief discussion of each; or, we are happy to send you a printout of the complete code of plant families in our collection, if you so request.
CULTURAL CODES--THE SECOND CLUSTER(S) OF LETTERS
Some of you grow only indoors, some only in terrariums; many of you have hobby greenhouses; while a growing number of customers live in subtropical or tropical areas of the world. These brief codes are an attempt to suggest whether or not a particular plant will do well in your particular conditions.
HP--House Plant, performing adequately in the ordinary home.
CGH--Cool Greenhouse, for ideal growing conditions; most low temperature plant rooms would also fall within this code.
TGH--Tropical Greenhouse, for plants needing constant warmth and higher humidity; also would describe growth chamber setup some of you have built in your basements.
TERR--Terrarium culture is most successful or appropriate.
HT--Hardy Temperate: winder hardy at least to Zone 7 or to Zone 6
HH--Half Hardy, possibly damaged in a prolonged winter, but reliable outdoors in Zone *.
...If an entry has the cluster HP CGH, this means normal house plant culture will be successful if the plant is given a cool CGH moist location; however if the entry has the cluster CGH HP, you would interpret this to suggest that while Cool Greenhouse conditions are needed for total success with this plant, House Plant conditions will be adequate, while not ideal. If the cluster is HH CGH you would interpret this to mean that while in Zone 8 or below this will be winter hardy outdoor, further north it will need considerable mulch, a cold frame, or a Cool Greenhouse to thrive. And so one.
HB-Hardy Bulb
SSA--Self Sowing Annual
y indicates a plant or groundcover popular in bonsai work
h indicates a bog plant, or an aquatic
v indicates a plant appropriate for terrariums

fl/fls--the flower or flowers of a plant.

URC--UnRooted Cuttings, cuttings usually shipped in most.
SASE--Self-Addressed, Stamped Envelope, which you include for our answers to your questions.
