Brassavola grandiflora is from the Pacific side of central America. I obtained this plant from Andy's Orchids in 2017. It is a care-free, easy growing plant, and it is relatively compact (height of 15-20cm). It usually produces much more flowers, but this time it produced only 2 flowers. It seems to flower more than once a year, and it seems to be aseasonal. I keep it at a warm end of intermediate temperature; the max/min daily temperature is 29-27/21-24C (80-85/70-75F) in the summer and 18-21/16-18C (65-70/60-65F) in the winter.
It is similar to B. nodosa. Frequently, people mentions the larger flower size and wider, flatter, less terete leaf than B. nodosa as the difference. Additonally, Withner (1998) mentioned that the different shape of the column (Fig. 5-2).

Hello there; I found your blog years ago when I was looking for tips on how to grow Corybas sp. I know this post is about Brassavola, but I decided to bring it up here instead of commenting on a much older post for ease of navigation.
ReplyDeleteHow is your Corybas geminigibbus doing? I have had a few opportunities to purchase Corybas species, but I usually pass them up because they're expensive, you only get a couple of bulbs, and it sounds like making the right media is tricky. If your methods have worked, I might try to emulate them at some point.
Mines are doing ok. As I replied to a comment of the original post a couple weeks ago: https://orchidborealis.blogspot.com/2016/04/corybas-geminigibbus.html, I wouldn't say that they are doing fantastic. But they are slowly increasing in the number of leaves.
