Brassavola grandiflora
 

:hello I've been looking at this brassavola for sale at Andy's Orchids. How large do these plants get? :thankyou

Brassavola grandiflora is considered a mini at about 6" tall. Mine (from Andy) came mounted and the stick is about a foot long, taking up far more space than the plant itself. Brassavolas have a tendency to branch a lot, so how large the plant itself gets depends on how willing you are to allow it to spread.
