I love star shaped Catts. and Bl Richard Mueller (Brassavola nodosa x Laelia milleri) as a parent gives some very nice results, many fine cluster-blooming catts, most of which bloom twice a year.
Richard Mueller is the parent of many lovely Catts. which are
good plants for indoor growers, as they tend to be compact, and bloom generously with flowers that tend to last. So an all around nice catt. I have lost tract of how many Richard Mueller crosses I have but I always seem to add a few more each year. Here are a few of my favorites.
