I bought a Maxillaria tenuifolia (Coconut Orchid) last summer at the RI Orchid Show. I purchased it when it was in bloom. I was moving plants around in my lowland terrarium and found that it bloomed:
I have three that I'm growing in lowland, intermediate and highland conditions. I have read that it does get down to a low in the 50F range.
It is fragrant with a strong smell of coconut. If I was limited to only grow one orchid, this one would be it.
