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.

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.

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.

My wife and I planted our althea about a year after we had our house built and it has done very well, that was six years ago. Although it suffered from aphids for a couple of seasons two years ago and after battling those pesky critters with several spray pesticides I tried a granular systemic around the roots… problem solved.
My wife loves this plant I have seen some hummingbirds come for a visit now and again I guess they like too!
I read some of the Negative reports about it spreading throughout their yard, land, drives, porches, etc… many of my family members have had altheas and they or I have never had this occur. My family member’s plants are between 15 to 30 years old and have never “wandered” away from the original planting area. I wish ours would spread so I can have more to put around.
All in all it has been a very easy plant to keep.

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.

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. I've seen some advice that says to trim off the old pods before the mature but realistically who can do that with large shrubs.

The growth pattern of this althea is less shrub-like than most I have observed in other gardens.

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!

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!

These can be really beautiful and showy plants, but they can also be high maintenance. To keep them looking nice, you need to do some pruning, which should be done in early spring (not fall!!) since they bloom on this year's growth. Also, like lilacs, old weak growth inside should be pruned out to let light in. They respond well to hard pruning if they get out of control. I have 9 very large altheas of different varieties and have had good luck with all of them in Kentucky. They grow very rapidly and bloom profusely. One white variety I have is still blooming here and it's October! It has bloomed all summer and is still covered in flowers. One of mine is a "tree" althea, pruned to one main trunk. Be warned that Japanese beetles LOVE these bushes -- I have to constantly spray them during beetle time or I wouldn't have any flowers left. That's the worst thing about them. They do also seed themselves, but I've only had that happened next to one bush and I've saved all the "babies" because I have 8 acres and plenty of room for them. I put the babies into pots and kept them watered all summer and they have done very well. My husband has complained because we have two very large ones at the head of our driveway and they are quite late to leaf out and look dead, as others have commented. Therefore, I wouldn't recommend placing them where that characteristic would bother you, like right in front of your house. But if you want a show of glorious blooms throughout the summer when most other bushes are not blooming, then these are for you!

One of my favorite plants here in central MS. One of the very last things to leaf out in the spring but grows well thereafter. I have several varieties, single and double. The single varieties that I have(I don't think they are of the goddess series) should self-sow, but that doesn't seem to be a big issue around here. One very nice thing about it is that it is not fussy about soils(we have lots of clay) except that it is susceptible to root rot so needs to have some winter drainage, and it seems to be quite drought tolerant. I rarely have to provide supplemental water to established plants. The bloom period is very long and the plants are in bloom often in the late summer when everything in the garden seems "tired" and I'm tired and don't feel like gardening much. Also will bloom okay in partial shade, though even here, the more sun the better.

I kept it cut down and forgot it one year and it grew and bloom with beautifully colored flowers, I am now trying to prop. by cuttings. I don't know where this one came from unless it's a cross from the lavender one and a white one that was growing in the field. The beetles don't seem to bother it, maybe their too busy with the other two.
I work for the Sacramento City Zoo and we Have the Rose of
sharon in various locations in the zoo.The purple is my favorite.I am currently growing two whites from a seed pod
for my own garden and waiting for the purple to pod for more

I have planted two rose of sharon one white and one pink in my beautifully landscaped front yard. We live on a fairly quiet street, but there are many passersby walking dogs and coming home from work.
In my opinion, the Rose of Sharon shrub is an eyesore until it finally gets leaves in late spring/early summer (Zone 6). The location of my shrubs are in my front lawn and they look dead. I have to explain their appearance to those who wonder when I'm going to remove the "dead" tree from my lawn. It's kind of embarrassing.
A few people have said "But when they finally bloom it's worth the wait". This may be true, but to have two 5 foot shrubs in dormancy until early summer is not attractive in my front garden. I think I'll move them to the back yard, and replace them with a shrub that "comes alive" in spring with the rest of the landscape.

These little trees or large shrubs are quite common where I am (Alabama) and have nice flowers like hibiscus. I find their growth rate good but they are very invasive and seedlings turn up everywhere! I got three from a relative's back yard. Sometimes I have heard them called Syrian hibiscus.
We have a Rose of Sharon in our back yard; it is over fifty years old. I know this because we have owned our place for forty years now and it was well established when we bought it. The tree has purple flowers on it and we have actually started another tree from seed. I think it is beautiful and as far as we know it is the only one around here. We live in the far northern part of California, approximately 100 miles from the Oregon border and 50 miles inland from the coast. For a long time we didn't know the name of the tree and no nursery around Eureka was able to help us out. Thank you for your database site.
I see all the notes from folks in other parts of the U.S. who are growing Rose of Sharon Hibiscus (Hibiscii ?). Well I am trying to grow one in CA. On the edge of the desert. I did some research to come up with this particular type and stuck it in the ground last fall. It has made it through a high desert winter, (dry with desicating winds). I had put one in the year before and it deceased. So now I'm carefully tending this one and it is doing well. About two feet tall at this time and the leaves are a healthy dark green and strong.
Don't know for sure the flower color, just as long as it's not white. I like vibrant colors in my garden.

I just bought a house that has several very large specimens of the double pink variety. They are on the West side of a South facing house, so they don't get full sun until 1 PM or later. They were the last item in the yard to leaf out. They have started blooming in the past several weeks. I haven't given them any additional water or fertilizer. They have dark and light pink double flowers. The bushes are 12'-15' tall. They are covered with blooms top to bottom.

Be careful to not over water especially if it is planted in a heavy clay soil because it is susceptible to root rot. I lost several because I thought they needed water when the leaves yellowed. Now, I very seldom provide supplemental water and they do fine. They will become spindly and/or will not bloom if they do not receive enough sunlight. I especially like the double lavemdar and the single white with maroon center ones which seem to bloom better than the others (at least for me).

Pretty plant, easy to grow, large enough to be used as a small shrub, but small enough to be included in the back of the perennial garden. Pratically fool-proof to grow and comes in a range of colors and patterns, (flowers), including a near-true blue! (I garden in the Mid-Atlantic).
The "single" blossom of the Althea is IMHO much more attractive than the "double" rose like blossom of the Rose of Sharon. The sunnier the bushier. Easy to grow in rich garden soil, but is very sensitive harder clays.

My sister, who lives in Centereach, NY, sent me two of these. (She did so because she didn't like it any more as it was too invasive.) The speed of growth was excellent, but it seemed to take forever to bloom. My patience brought me luck; one did bloom for me (finally). The flower was beautiful and because of that, I don't care if it becomes invasive!!

My mother-in-law gave me two plants about 5 years ago. They were about 2ft tall, and now are 20 ft tall. And I now have over 250 plants from these two trees. They are very easy to grow. The seeds fall to the ground, or the wind blows them when they fall, and before you know it, you've got more plants. You will have enough to share with everyone. Very hardy trees/shubs, pruning is easy to remember...on Valentines Day. Very beautiful plant and so easy to keep up. When all else is dying, these plants are blooming beautifully!

Howdy folks. This is one of the easiest and most rewarding plants you could ask for. It easily propagates by seed. We have hedges of them. What a great plant for those of you who would like to get a fast-growing showpiece/hedge. If you know someone who grows these I'm sure they'll be more that willing to share. The seeds readily drop to the ground and easily send up young plants in the spring. These don't even need to be dug out, just grab hold of them and pull. They will easily come up so grab as many as you are allowed. When you get them home you'll find they root very easily; so easily in fact that many folks just take a large screwdriver (or something similar) and poke a hole in the ground, wallow it out, insert the young plant, water it, and stomp it down. If you keep it moist for a wk you'll have excellent success. Truly a low-maintenance plant from day one!

This shrub can be stooled to maintain compact growth. They come in a large variety of colors and bi-colors; some are single and others double. Doubles tend to be sterile, resulting in no unwanted seedlings. Newer hybrids are self-cleaning.
Full sun is required for best bloom, but will grow well in part to full shade. Some of the newer cultivars have variegated foliage.
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.
