I planted this plant several years ago on the sunny west side of my house at the base of the downspout. It has loved this location and never fails to impress and please with its tremendously heavy flowering. I still think it is one of my all time favorites in terms of the hardy hibiscus selections. The cut leaves with a reddish tint only add to its ornamental appeal.
I have 2 Fireballs and when I moved, I up-rooted them. Which was not easy and very scary considering I did this in January 2006.
I originally planted them in 2003, so when digging them up I had to cut LOTS of roots,thats what scared me. Wasn't sure they would make it. But, woola. Transplanted Fireballs came back stronger then ever. LOVE these plants. We get lots of cold weather here in Amelia,Ohio (25 miles east of Cincinnati). Everybody in the neighborhood has come down to see and marvel over these plants. I have them in full sun. 1 is in a very low spot where it stays pretty wet and the other is in a more dry area.They both do great.

I purchased 3 Hibiscus "Fireball" Rose mallow plants in June and was concerned they would not do well in Michigan. Up until this week I almost gave up in seeing any buds. One plant has about 7 buds, the other 2 buds and the 3rd has none. I can't wait to see the actual flowers, but it sounds like I'll need to be patient. All suggestions recommend cutting back in the fall....ouch, but I guess I'll have to do it. When they flower, I'll send photos.
We used this plant a lot recently in landscapes and I just think it's beautiful. Even the couple we have left over are thriving while still in a pot. They have seemed to be very strong plants who love lots of sun and water.
The most floriferous, cold-hardy, and drought tolerant of the hardy-hibiscus introduced by the Fleming Brothers of Lincoln Nebraska. One misconception is that it needs a lot of water to survive. It does prefer water when coming out of its late dormancy (May-June in Zone 5). After it has become established, the plant is extremely drought tolerant. It has beautiful 10-12" bright red, campanulate, flowers. When cut, place the flowers in water in the refrigerator until placing where desired to keep the flowers lasting longer. Cut the foliage back to the ground after a hard freeze to 3" from the ground. This plant can also benefit from a 3-5 inches of mulch to help protect over cold winters. Remember that this plant breaks dormacy later than most plants so don't give up on it!
