I am having trouble with this plant. The leaves are yellowing, guessing too much water, so now since rainy season is here I quit watering it. Well add more later.

Produces large spikes of purple flowers with red centers, mine bloomed in late November here in Central Florida. Long lasting blooms, easy to propagate. Placed in an area that gets some morning and some afternoon shade, although grows tall, about 5 1/2 feet now, so captures a little more sun than those plants around it. Seems pest free so far.

I purchased two of these beautiful plants in mid July 2011, transplanted both of them into large planters and they are outside on the patio facing south. In the last week and a half one of them has blossomed several gorgeous purple flowers, unfortunately the other one which is almost identical in size and exposure has not blossomed at all. They are both approximately 7 feet tall. I have successfully taken 3 " and 6" branches, inserted in a glass with water and they have both rooted and then were transplanted into soil pots. Would like to know if all are usually bloomers or possibly depends on the sex or ? Both were purchased at a nursery in Robertsdale, Al.

I was given a cutting of this plant and successfully rooted it. I live in zone 8b and was told it is not hardy here. I have had it in a pot and brought it in each winter for at least 3 years. It is now too large, at 6 1/2 feet to continue to move in and out. I took a new cutting and planted this one in the garden. The late summer blooms are beautiful, but messy when they drop petals, so not ideal to have it indoors. It took a few years before it bloomed.
