planted this last summer, no flowers that year and only 18" tall. It is currently 6 feet tall and has been covered in blooms for two months now! It is huge! Bees and hummingbirds seem to be very attracted to it. Wondering if it will die down this fall as it was evergreen all winter here even with -8celcius in the mountains at 4800 feet in México.

Tried to grow these in Orlando. These wilt in the hot sun, but otherwise seem to be easy to grow, except they didn't bloom the first year. Bloomed in June from seed the prior year. Beatifull pest-free foliage.

It seems I am having a different experience with mine than some others-if you look at the pic I uploaded it kinda sprawls..I bought it last year at a nursery and it was a tiny things that the rabbits ate everytime it got a couple leaves. Well this year it is HUGE!!! I am going to have to either move it or everything around it since it is at least 2X the size I anticipated!! I thought it would be slender stalks not the gargantuous thing I have-beautiful though w/ purple flowers!!

i grabbed this plant at a nursury not even knowing what to expect, now its one of the best flowers in my garden. It flowers throughout the entire spring and summer where at least one flower can be found at all times, the colors are unbelieveably vibrant.
This plant grows quite tall quickly , but doesnt seem to bush out at all and keeps to a couple slender stalks, best planted in the middle to back of the garden
My Zebra Mallow started growing wild in my flowerbed. I assume the lovely birds transplanted it. The greenery itself was so attractive, I just couldn't pull it out. Then to my surprise, beautiful purple striped blooms started appearing inside the plant. I'm glad I was able to identify it. I look forward to enjoying it's full beauty. Oh, it seems to have a few more starting to sprout. Very easy to care for . . . I've done nothing!!
A pretty flower, but it LOVES to self-seed. I have it coming up everywhere. It has a long tap-root that makes it hard to pull up without landing on your bottom if it gives! My information says hardy in zones 3-10. Other names include High Mallow, Malva, Tall Mallow, and Zebra Hollyhock.
