I have 1.3 veiled i kept out this summer. i used two hibiscus & two umbrella plants. one per cage. the hibiscus will offer more shade & sturdier branches. i didn't notice a preference from anyone. just make sure to get some horizontal branches in place for the plants to grow around. that made the difference. all 3 females are now pregnant, if that figures in to your equation. lots of misting also!!! watch for open mouths, means they need water NOW.
