Growability scale = 7 (1=extremely easy, 10=very difficult)
Photo Oncidium lanceanum is one of the so-called "mule-ear" Oncidiums, characterized by large, tough arrow shaped leaves, medium green in color with maroon spotting. Many of the mulies dislike very high light which will in fact burn holes in the leaves of some plants. Onc. lanceanum grows to 18-20" tall, throwing a 2 foot tall spike straight up. The blooms are about 1" wide x 1.5" tall, golden in color with darker spotting. The lip is the real attraction, ranging from light pink at the bottom to dark pink at the top, including the callous. It is extremely fragrant. It is also extremely slow growing, hence it's high score on the growability scale. It generally does not make a good pod parent, the progeny having a tendency towards muddy colors. We grow Onc. lanceanum in relatively low light levels compared to most Oncidiums, generally in the 2000 FC range. Plants should be moved to a dimmer location at the first sign of leaf distress!! This will be first evident in the leaves becoming slightly yellowed. Severe burning will cause unsightly holes in the leaves. Temps should be intermediate, 60's-80's, Water when the plant is just becoming dry.
