I have the red version which I guess is more prevalent. First time I saw this plant was this year and loved the leaves on it. Then when I saw the bloom what a bonus. Great plant. Upright growth and shapely leaves and then the blooms are huge and gorgeous.

White version of our beloved Texas Star Hibiscus. The seeds from this variation do indeed, for the most part, bloom white. A few red are found, but they are easy to tell apart long before they bloom. The growing habits and leaves of the alba variety are different from the red. The red variety leaves have a red tinge to the stems and leaves. The alba variety does not. My experience has been that the alba variety has much more side shoots, and thus more flowers, than the red variety. It is also amazingly drought tolerant (as opposed to the red variation) when well established--height here is 7'-9'.
