Have had Rose of Sharon in all of my gardens over the last 35 years. Beautiful blooms in August in mid-western Ontario along Lake Huron. However this plant, at this location and climate is completely invasive through self-seeding. I literally pull hundreds of seedlings each year from only two mature plants. Have propagated many as gifts and along a fence line with absolutely no difficulty. Most beautiful when plants of two colours are grown in the same spot to produce a variety of blooms, mine are pink and purple. At this location the Rose of Sharon is far more robust than my hibiscus and not at all prone to insect devastation.

With only 500-600mm rainfall here, it rarely self-seeds, not to mention becoming a weed. I always loved this plant and just planted 80 of them. Their leaves are said to have medicinal value, the flowers edible. I will try them once.
In fact, I got so many plants because of the tortoises I keep: a welcomed and nutricious supplement with lots of pollen, right when the native broadleaf weeds are scorched in late summer; quite a famine time, and tortoises usually would fast, burrow and aestivate for a while otherwise. So, instead of a few difficult weeks, the juicy flowers fatten the torties and get them in good shape for the hibernation.

Beautiful; covered with bees, visited by hummingbirds, but HORRIBLY INVASIVE, spreading by seed. Come late spring into late summer, I am ripping out seedlings out by the high hundreds. And only because it's my neighbor's and they know nothing about controlling their huge, out of control, monstrosity. I have one, which I faithfully prune and attempt to remove the spent seed heads, but even so, that one still manages to reseed, just a few seedlings I am happy to say.

I have two long hedges of Hibiscus Syriacus in the North of Italy zone 7a. I have all the four colors but I collected seeds in Connecticut from a plant that seemed to have a darker shade of blue. The new plants that I got form those seeds have much more variability in colors that the local indigenous plants and also bloom about one or two weeks before the other. The only thing that is a bit annoying is that this plant has an insect the Firebug, ( Pyrrhocoris Apterus ) that tend to make colonies at the base of the plant.

I am a +/- on the Althea. My garden is in a micro climate zone 6b with river bottom soil. Between my neighbor's box elder and mimosa and my Althea, I spend most of my year pulling volunteer seedlings out of my flower garden. As a new gardner I planted a "tri-color" Althea purchased at a garden club sale. I liked where it was, but learned to be brutal to it. I trimmed it to the least vigorous leader, making a nice 7 foot rounded tree with white flowers. It requires removing seed pods and pruning in the fall , but is a nice counterbalance with my climbing rose and lilies. Would I plant another one, no way.

I grew althea for over 15 years in the CA mountains (about Z6) in soil that was quite acidic. Never a problem of controlling the plant. I've had several of them in central OK for the past 8 years and I love them. There has never been a hint of invasiveness, and I have at least 4 different varieties. The soil here is neutral, running a bit to alkaline.
I recently took some cuttings off a plant that I really want, and was pleased to see that all of them seem to be rooting.
Unless something changes drastically, they will remain one of my favorite large ornamentals. For me, they are less care and bloom longer than the big crape myrtles that also are so popular here.

Living in Knoxville TN, I have had the opportunity to do some yard maintenance for friends/neighbors. What grows here is a small tree - no shrub. And, invasive??? Get yourself some very strong hands, for you are going to need them - for 100s of these trees' horrible shoots. They immediately put a root straight down to H***. The longer you let them stay in the ground, the taller the plant and deeper the root. Cutting the root at the ground's surface is a sure-fire way of having it come back in less than a week. Round-up merely poisons the soil but does nothing to kill the obnoxious seedlings. Don't say you were not given a warning!

I also consider this plant to be an invasive weed (in my PA zone 5 yard.) One came with the property when I bought my house, and it appears to propagate via running roots, like raspberries do. The original shrub I had torn out, but it had already established itself across the chain-link fence into my neighbor's yard. They love it, unfortunately, so I'm still yanking out shoots along my side of the fence & hacking off branches that grow between the links and droop over the fence into my yard, to give my own plantings some room and sunlight. Worst thing to plant IMHO, unless you've got a few fallow acres you don't care about.

The most invasive shrub I have ever encountered. Throws seeds all over the place which in turn grow new shrubs. My daughter has a ton of them from previous owner and I use nearly a gallon of roundup every spring to kill off the seedlings and pull the ones out that just won't die. Hate it with a vengence. If they weren't so huge, I'd pull every one of them out and burn them.

An aggressive self-sower here in Boston Z6a. Even the cultivars bred for sterility are not truly sterile.

I've maintained some by pollarding, cutting the pod-bearing branches back hard annually just before they begin to open in the fall, and this seems to help reduce self-sowing and improve flowering. Still, they're a lot of work. For a shrub with late summer bloom, I'd rather grow the new Z6-hardy crepe myrtles (Lagerstromia).

Exceptionally late to leaf out in spring, not till June here.

Individual flowers last less than a day, closing in late afternoon, except for one or two cultivars.

When I moved to Kentucky, I was told the property had two "beautiful" Rose of Sharon trees. Coming from Wisconsin, I had no idea what those were. When they bloomed, I thought they were gorgeous.

Until the following spring when I found there were hundreds of seedlings in the flower bed I was rehabilitating. There are also hundreds of them in the woods at the edge of the property, along the road to our house and pretty much anywhere within a five mile radius of ANY Rose of Sharon tree.

The USDA lists it as invasive in Kentucky (it actually has it listed as Weed of the Week) stating it crowds out native plants. For that reason alone, I will never plant this again, and will try to pull as many seedlings from my property.

Can't wait to see how my plants will turn out! I just love these flowers and had to dig some up while on vacation. I have the normal hibiscus but wanted something else as well. I have about 8-12 newly transplanted plants from my Grandmas house in west Virgina and brought them down to FL. Each plant right now is about a foot or so tall and doing great in their new home after 6 days of being in FL "dirt" (for those who are not familar with FL dirt its a nasty gray sand). Even noticing some bright new green leaves on a couple of them. One looked like it wasn't going to make it and was rather wilted for a few days but now starting to straighten up.

I took cuttings from my Dad's old home because he is gone now and his Rose of Sharon is still with us. I in turn have given cuttings to my children. Originally we planted a couple cuttings by the chimney but moved them when they got too big and now they are by the deck. Hummingbirds love the blossoms and as far as being invasive, I just weed the new sprouts as they come up. My only problem now (July) is Japanese beetles. I will spray but a mother robin has built a nest in the foliage so I will have to wait until her babies leave. I have both purple and white/rose. The white/rose is my favorite and a bit more rare, I think.

To all that love this plant/tree: I have posted two pictures of this wonderful plant. I tried over and over to propagate this plant with no success. Then one day, during my yearly inspection for my nursery my inspector said try air propagation. I thought to myself, da, I should have been doing that all along. It worked, and it did not take the three months I was told it would, it took 5 weeks. I only have about 30+ plants left (friend and family have the rest). I plan to propagate this plant till the day I die. It is beautiful, and I have not had the problems that others have talk about. My grandmother had a solid pink one when I was growing up, now I have a blue/lavender one. Its like having a wonderful carnation tree, as they do look more like a carnation.

I have spent every growing season for the last 17 years pulling up seedlings in my garden beds and mowing over those in my lawn. Still, what began as ONE "tricolor" bush - really three different color varieties in one large pot - has managed to spread all over my yard. I foolishly allowed it to grow to maturity in a few spots and, despite my best efforts to clear these spots for new beds, the roots still survive and send up shoots. Will be clearing off snow and attacking with a drill and salt-vinegar solution in a few months, as suggested by a local landscaper who thinks he eradicated them from his yard two years ago.

Normally I would steer people away from Rose of Sharon or at least give them a warning. The weedy varieties of this plant are beyond aggressive. However, with skepticism I planted Althea and I am pleasantly surprised. I've had 3 shrubs for 5 years and they are very slow growers as opposed to their cousins and they don't reseed much at all. I've got other ROS nearby so I can't be sure whose seeds they are, but I have my suspicions. For those of you who have mature shrubs yet despise plucking the millions of seedlings out of the ground every spring, try planting pachysandra under the shrubs. I found this out by accident when a patch crept under some of my shrubs. A thick patch of pachysandra works like a charm in choking out 99% of the seedlings.

My neighbor has a lovely althea which is in full bloom right now. However, the plant has become rather top heavy in growth. Currently our weather here in New Orleans is bringing daily heavy rain showers causing the canopy of the tree to bend severly. Seeking advise on how best to deal with this problem while maintaining the beauty of the tree. Should the tree be pruned and if so, how should this be done? The growth pattern of this althea is less shrub-like than most I have observed in other gardens. This specimen is more in tree-form, growing from a sturdy single trunk and spanning out and upwards with single long branches which, when pounded by the rains, bend and droop almost to the ground. Any advise wold be most appreciated.

The bicolor white and red single bloom variety has been passed along from generation to generation in my family for at least five generations and likely well over 100yrs. If you are looking for a viariety that does NOT freely self seed, ours doesn't and has been passed along by cutting. I can't remember any seedlings popping up, but it does grow exceptionally well from cutting. The down side is it doesn't like to grow in tree form, and as soon as you prune it new branches form within the week. Otherwise, it is very hardy and disease resistant.

The double purple variety seems to get aphids easily, but the white and red single has so far been pretty resistant. Overall a very nice plant with lots of sentimental value!

I could be wrong, but I think the problem you are having with self seeding may be due to the variety. I have a beautiful, ten-year-old Blue Bird Rose of Sharon that has never self seeded. So, just ask for the infertile varities. I love my Rose of Sharon well enough that I'd trim off the seed capsules or weed around them if I had to in order to keep it around. Crepes and Rose of Sharon are garden mainstays in OKC when the heat cranks up and some plants just give out.

I agree the plant is invasive, but the sturdiness of the plant and the bloom make it worthwhile. In addition to bees, hummingbirds love this flower. To keep the seedlings under control, cut the immature seed pods off before they ripen. Don't be afraid to prune aggressively to keep it in shape. They love a good haircut and will come back full and well-shaped. I agree also that they belong in a place where their bare branches are not noticable, but surprise you with an unexpected show later in summer. Good luck cutting it down! It will probably come back from the roots.

This shrub is deciduous in Zone 7. It does not leaf-out until late spring - early summer making it easy to forget it is there. However; the long blooming season provides a profusion of bright reminders of why you want to add it to your landscape. The majority of varieties are NOT self-cleaning and you need to remove dead blooms to encourage and prolong the blooming season.

A shrub or small tree, with numerous upright branches, Althea reaches 8-12' tall and 6-8' wide. It is valuable for late-season flowers. Use in groupings, masses, shrub borders or hedges.

Flowers are single or double, white to red or purple or violet, or combinations, 2 to 4" across. Usually blooms July through September, depending on zone. Flowers are produced on new growth. Grows in about any soil except those that are extremely wet or dry. It does best in moist well-drained soils that are supplemented with peat moss, leaf mold or compost. Prefers hot weather; prune heavily in early spring, or prune back to 2 to 3 buds in spring to get large flowers.
