Mini Orchid

On the left is a regular orchid that I've had for a couple of years (loses flowers after 3-4 months and then goes dormant for about 6 months) and on the right is a mini orchid that I just bought.  I'm not happy about the fact that today I see half of the flowers are dying because that means it's about to go dormant.  I do like the minis, though, and will buy more next spring.
