This is a climber. Arbuscole is a miniature bushy type but elatior is a definite climber and this hybrid has that growth habit. I like them as they make grand displays. I let them climb up a 3 foot branch and if they reach the top turn it around and let them go the other way. This one is a young plant, 1st bloom. You can see the next growth at the bottom of the stalk. If they fail to do this and just keep going up, after 3 to 4 growth one can cut the stalk to train for a bushy appearance.
