The growth rate of this plant is amazing. It was obtained as a start in a 4″ pot in May and by the end of the season it is about 8′ tall and 3′ wide. It has suffered in our winds a little and two “branches” broke off from the main stem and are now laying on the ground, but they continue to grow. The leaves are huge – 6″ to 8″ across, and seem to stand up to weather really well so far. It is fun watching them flap around in the wind.
This plant is somewhat picky when it comes to temperature. It doesn’t like being cold and it doesn’t like being hot. That makes it a perfect plant for us because our typical temperature range is very constrained apart form a few hot days during summer – and we could anything over 80 as being hot.
In spring, we are looking forward to seeing it bloom. They should be 3″ white sunflower-like blossom with black centers surrounded by a olive-green halo. This really is the perfect plant to straddle the tuxedo garden and the garden of the giants.
