It grows beautifully here in Austin, TX. I have seen my daughter's freeze down to the ground and bounce right back. I have found them easy to root from cuttings. They are large, striking displays in bloom.
I love them.

Easy to grow from cuttings. Took awhile to bloom. Likes epsom salt, fish oil and compost tea. Blooms non-stop. Leans toward the sun.

I have not grown this plant. Giant Mexican Turk's Cap, Mazapan, Turkscap Mallow, Sleeping Waxmallow, Sleeping Hibiscus (Malvaviscus penduliflorus) is native to areas from Mexico through Central America to Columbia. After being introduced in Hawaii, Texas, Florida and Puerto Rico it has become naturalized. It will grow in Zone 8a and 8b; however, it will freeze to the ground after hard freezes to return in the spring. The stems have fairly dense split hairs.

The serrated leaves are oval or sword shaped, mostly unlobed and 4 to 10 cm long with a pointed tip. The flowers are 2 to 2.5 inches (5 to 6 cm) long with protruding stamen and are humming-bird ... read more
