I normally do a reasearch first before I buy any. In that way, I know exactly what i want when i go to the show or do online order. Normally i will give it a try once or twice or keep it in the collection for a while. If the plant doesn't bloom for me after 3-4 years, it's time for trade off or resell. But then some plants are hard to resell because of the inital cost, aka. My Paph. Prince Edward of York. I got it as nbs seedling 6 years ago, and its two growth right now, and iam 2nd guessing if i want a plant that only bloom every 4-5 years. =) And mine still hasn't bloom yet.
