Bulbophyllum Grace Thoms (Bulb. echinolabium x Bulb. paluense)

I brought this plant about three years ago as a three bulb division.    Initially, the plant didn’t had much by the way of roots so growth was slow.   After the first new growth produced roots the plant grew better, with larger growths.   However it didn’t bloom until the plant had accumulated several large and plump pseudobulbs.  

The inflorescences are wiry and I didn’t notice them at first.   The inflorescences in my plant open their flowers sequentially, having just one flower open at a time.  The flowers are large and striking, you can easily see the echinolabium parent influence in them.

This plant is cultivated in a relatively small pot, about five inches wide, in bark with some Styrofoam peanuts in the bottom of the pot to aid drainage.  The plant gets watered twice a week when it is in full growth and it has not rained in the previous few days.  When it is not in its growth phase it can go one or two weeks without watering with no sign of distress.  But when it is producing pseudobulbs I don’t allow it to go bone dry.

The plant get full sun for about two hours early in the morning and then sunlight filtered through the canopy of tall trees.    During part of the year the sun comes up in a gap between two large trees this means that the plants get more hours of direct sunlight early in the morning.  They have shown no ill effects due to the increased light exposure.  

I have not been able to detect any fragrance from the flowers.  However the flowers are attracting the local flies, so it is probably producing at least some fragrance, probably with a distinct fecal smell.   I found one fly stuck to the fluid in the stigmatic cavity.  I released it and it fled with alacrity.  Other flies were seen in the vicinity but so far only one has become trapped.
