Planted in a protected, full-sun location this plant overwinters in Northeast Florida. Must have lots of space to climb.

I planted it this spring and so far, there have been very few blooms. We thought it was going to be awesome, but the cardinal vine is outshining it. It's on a very tall, wide iron support with sun almost all day. Any suggestions?

This plant has the worst hooks on the back of the leaves and down the stems and trunks. They do not just cut you, they take hunks of skin out of you for the spines hook under and grab your skin in many places. Even with minimal contact it gets you! Does much more damage than the thorniest of roses. But it is so beautiful!

This beautiful member of the nightshade family can be grown in a large container as a speciman plant. It climbs 3-4 feet high with hook like spines. In the heat of summer it will be covered with large clusters of lavender, 2.5-inch flowers. To over winter cut plants back by one half and store in a cool room with little water.
