Hibiscus moscheutos. These eye-popping beauties are, surprisingly, not well known here. Many people can't believe they can grow here. Believe me when I say, they can, and do!! No special care required.

Gardening picture

.While sitting in front of the fan one hot, muggy afternoon, drinking a cup of coffee, I was startled by the sound of screeching tires outside. Fearing a cat had escaped from the closed in porch I ran out and Imagetook a quick head count, decided all were present and accounted for. Only then did I look farther into the street. There was a man behind the wheel of a van looking sheepish and apologetic while pointing to my front flower bed. In the flower bed was a woman with a camera taking pictures from every conceivable angle. She was capturing the plant in the picture to the left. Hibiscus moscheutos. Of course I had to go speak with her!! I ran back in and grabbed my coffee, preparing for a tour of the gardens. I figured if her Hubby was the sort to come to a screeching halt for her to take a photo, he wouldn't mind waiting for her to take a little stroll. He might even join us. He didn't, deciding to stay in the air conditioned comfort of the van.

We got to talking, her and I, and she asked what was the name of this beauty. I told her it was a Hardy Hibiscus. Here is where she got confused, she couldn't get the tropical version out of her head, so I took her to see my braided one and tried to explain the difference. The tropical kind, Hibiscus rosa-sinensis, can't be subjected to cold. There is a wonderful article on those beauties by our own Islandshari here. The Hardy Hibiscus, however can withstand months of freezing, covered in snow even. Hard to believe eh? She thought so too. I offered her and her DH a coffee, she declined with a brief look of disbelief and pulled a frozen bottle of water from the van. People just can't grasp that drinking something hot, when you yourself are hot, makes you feel cool. But, that's a different story altogether.

Back to the Hibiscus at hand. I took her for a short tour, trying to focus on the Hardy Hibiscus scattered all around. Explained to her that, yes, they are planted there permanently. Yes, they do come back every spring in our zone 5a conditions. We have had temperatures in the winter down to -30C (-22F)Image and they still keep coming back, bigger and better every year. I don't give them any special treatment in the fall, no mulch, no burlap wraps, fend for yourself. That's the kind of gardener I am. And they come back. During the hottest summer days, they may need a drink if it hasn't rained in a while. They can get droopy looking if they get too dry, but other than that, nothing. I don't even fertilize them. They are one of the last of the perennials to poke their heads up in the spring. Just when you may think they have succumbed to the ravages of winter, give them two, or three, more weeks. They are surprisingly fast growers once they start. I have never tried to divide them, but they start easily from new shoots, in water or soil. I gave the lady a few I had in pots out back to take home with her. As they get older and bushier they might require staking. I push bamboo stakes in the ground in 4 or 5 places around the plant and wrap whatever I have handy around the stakes, like a fence. The blossoms, which are dinner plate in size, do not appreciate wind. No worries though, since they are covered in buds, with open flowers daily from the end of July right up until frost.

By this time, the lady's Husband was looking like he may doze off right on the steering wheel. She figured she had better get moving. I figured she had a pretty good Husband there. She went away with a few Hibiscus moscheutos of her own, among a few other perennials I had potted up, out back, waiting for new homes.

So please, all of you Northern gardeners, look for this beautiful perennial. I have found them in garden centres, mistakenly labelled as annuals. The leaves are easy to spot. The stems are red. They are worth it, traffic stopping beauties that are easy to care for. And, they WILL survive the winter.

Subject: Too late to plant?


Posted by kmargrave (from Colorado Springs, CO) on July 22, 2008 at 2:52 PM:

Great article! I bought three Rose of Sharon hibiscus plants last month and finally got them planted a couple weeks ago. (All three are doing very well, and one is blooming already!) Now I want to try Hibiscus Moscheutos; is it too late to plant these? I'm in Colorado Springs, zone 5, and just found some at auction (?!).

Happy digging,
Karen

Posted by threegardeners (from North Augusta, ON) on July 22, 2008 at 4:42 PM:

Not too late at all!!

Get them planted, they still have lots of time to get established before winter sets in. Give them a good drink in really hot weather until they do get established. I've bought them at garden centres in the fall clearance racks and they've done fine planted that late.

Congrats on your new find!!!

I live in Central Florida (zone 9), and CANNOT grow regular hibiscus!! They freeze every year. So, in sunny Florida, I'm going to get me some of those hardy ones! Thanks.

I have one old hardy hibiscus that I've had for years. I have saved seeds from it and and wintersown them and those babies are doing great. I've had them for 2 years.

Nice article, Lee Ann.

Thanks Karen.
I've never had any luck with the seeds up here but it's good to know they can be winter sown.

Posted by karen_cajun (from Deville, LA) on February 11, 2008 at 9:10 PM:

I have planted many of these hibiscus here in Louisiana & people LOVE them. In fact, here we call them the "DINNER PLATE" hibiscus because the flowers are literally bigger than a dinner plate.
I am a landscaper & recomend these wonderful plants for anyone who wants low maintenance & magnicificent flowers. The only downfall I see is they usually do not seed for propagation. Cut back in the winter & mulch heavily & fertilize well in the Spring & stand back & watch.
I am mostly amazed @ the men who like this plant. Men who do not even like flowers go out of their way to see these plants bloom every year.

I hope this does not happens on in the South!

That is a beautiful colour!!

I'm glad you liked the article.

Posted by suefalls (from Sioux Falls, SD) on February 11, 2008 at 10:32 AM:

I am glad you wrote this great article to let people know about these beautiful plants! I am in zone 4, and it is hard to believe that they come back year after year here too! The first couple that I planted didn't come back the next year, so I thought that they might not be hardy here. I enjoyed them so much though that I planted a few more that year,and figured I would still enjoy as an annual. I have now enjoyed these same plants for 3 years, and they are more beuatiful each year! So don't give up if they don't make it the first try!

Posted by MarthaJS (from Caledon, Ontario

Great article, Lee Ann. Right now in my garden the temperature is near 0 Fahrenheit, and my hardy hibiscus are buried under about three feet of snow, but I have no fear for them--they will return. I also don't give them any winter protection. They are quite easy to grow from seed, if you can find the seed--not that easy to find. As you pointed out, they come up later than most perennials, well into June for me, but then they grow very fast and bloom by August. One summer when mine were young, I dropped something heavy on one of them and broke it right down to the ground. I thought it was done for, but sure enough the next summer there it was, completely forgiving of its bad treatment. A wonderful plant!

Thank you for the fun and informative article. Last year was my first time overwintering this plant and I agree it was so slow coming back I almost uprooted it. When it did, it was worth it. Glad you are inspiring more people in all climates to grow this lovely bloomer.

Looking forward to the article on drinking hot coffee when it is hot!

I bought my second hardy hibiscus last summer - we haven't actually managed to plant either of them. The first one died inside - I figure #2 has a better chance outside than in here where nobody ever waters it. Beautiful pictures and article!

I enjoyed the tone and the content of this article. Of course, I planted ten rose bushes this weekend and needed some light, fun reading to enjoy after that workout.
I have seeds for hardy hibiscus so I'll put some in soon. They're going alongside the shed to relieve the eyesore. Who wants to look at the shed when I can these instead. Nice article. Inspiring.

...

Posted by threegardeners (from North Augusta, ON) on February 10, 2008 at 9:35 PM:

Thanks all.

They are, by far, one of my most favorite perennials. I'm glad the article was enjoyable :))

Posted by soapwort243 (from South Milwaukee, WI) on February 10, 2008 at 9:59 PM:

I have a white one, with a little red center, in my back. It is very pretty, with large blooms. Then, I visited a friend and she had a very dark crimson--(almost a black) in her front yard and it was a tire screecher !! I have been looking for one like it-(to no avail), but had to settle for a dark red. I planted it in fall, in my front yard. I have my fingers crossed that it will be a tire screecher !! :)

I have the Pink Hibiscus. I got it at a Flee market in Mobile Alabama. It is like she wrote. It comes back every year just as pretty as ever. I'm in Zone 7 It is the prettiest plant I have in my yard. I will be looking for more different colors this summer. I really didn't know exactly what it was called. But I love it. It blooms all summer long. Thank you for the info.

Hi Fitsy ~ why do you say yours are unhappy?

...

Posted by MistyPetals (from North Augusta, SC) on February 11, 2008 at 7:18 PM:

I hate to jump into some one else's Q&A but I'm wondering if the soil was the cause of the disappointment experienced.
Somewhere I read not to overfeed these plants or they are, to use the word used, unhappy.
Any plant that yearns to be neglected is a challenge for me because I tend to coddle mine.
Some plants, from my limited knowledge, want to be, like Garbo, left alone. No food, no water. No nuttin'.
Then again, these are probably, the thriftiest in terms of amendments,wouldn't ya say? Hmm...?


...

Posted by threegardeners (from North Augusta, ON) on February 11, 2008 at 7:29 PM:

I've only ever had a problem with one of mine, and the soil in that area of the garden was lacking in nitrogen. His leaves turned yellow.
As a rule, I don't fertilize, just compost. As long as they are given a good drink when it's hot and dry, they are pretty tolerant.

Good news for me! If only I can get it (him?) planted and he's not dead yet!

Posted by seedy1 (from Bessemer, AL) on February 11, 2008 at 10:26 PM:

I would love to have one of these hardy hibiscus. Where might I order one or do I just keep a watchful eye out at my local gardens shops? I just do not recall ever seeing them before at the shops though. Thanks for any advice.

...

Posted by threegardeners (from North Augusta, ON) on February 11, 2008 at 10:28 PM:

I've never seen them on-line, but then I don't shop online all that often.
Maybe someone will pop in with an answer,

I'd still keep an eye on the garden centres though.

...

Posted by lbontrager (from Aurora, NE) on February 12, 2008 at 7:05 PM:


For Seedy1... you can find some at [HYPERLINK@www.plantdelights.com.] I know I have seen other online sites that carry them.

For soapwort 243... If you want a dark crimson, try Robert Fleming. It is almost black/red and has attractive deep green foliage. It is compact and shorter than the average hibiscus. I have about a dozen and it remains my favorite.

...

Posted by carrielamont (from Milton, MA) on February 12, 2008 at 7:50 PM:

Seedy,

I bought both of my unfortunate hardy hibiscus locally, one at a local garden center and one at a Farmer's Market. In August, I think, in both cases. You can also grow them from seed.

x, Carrie

Posted by tcs1366 (from Itasca, IL) on February 12, 2008 at 8:34 PM:

Carrie -- any idea if the WS well? i have a bunch of seeds. colors?? i have no idea, the envies just say "Hardy Hibiscus".

Posted by carrielamont (from Milton, MA) on February 12, 2008 at 8:49 PM:

I've heard they do, never done it myself. Good luck! x, Carrie

Posted by Fitsy (from Hayesville, NC) on February 12, 2008 at 9:54 PM:

Hi, Podster and Misty Petals, thanks for your interest.
Well, they just aren't flourishing. They start to bloom, and
then sort of decide to quit. The plants are puny.
I planted them in 2006 in right stiff clay, so I prepared their
space with lime, peat, and granite dust, and used Schultz
liquid 10-54-10. The instructions that came with them said
to fertilize every 6-8 weeks, but since planting them I have only
put composted tree trimmings on them - and some manure
tea. No response. Interesting about overfeeding VS the
instructions. Oh, and they are on a sort of hump of ground,
so plenty of drainage, I reckon.,
Fitsy

...

Posted by podster (from Deep East Texas, TX) on February 13, 2008 at 12:50 AM:

Ms Fitsy ~ did the leaves continue to look good but the blooms petered out?

...

Posted by Fitsy (from Hayesville, NC) on February 13, 2008 at 10:06 PM:

I would say the whole plants (3 of them) look sad. Last
summer on their page in my notebook I wrote that they
looked "bothered". Right vague! I'm afraid that I don't
"read" them very well. Never been around them before.
There is a lot of charcoal on the ground there from some
fire in the past. Maybe an awful chemical is there!
However, the wild lambs quarters are happy there,,
and wild blackberry is invading with healthy looking shoots.
I actually had to lift an hibiscus to free it from a blackberry.
Every winter I grub out blackberry roots, and I am winning,
really, I am!
Fitsy

Posted by podster (from Deep East Texas, TX) on February 13, 2008 at 11:16 PM:

Hang in there. I wonder if the blackberries like your soil, perhaps the Hibiscus require a different soil PH. I am afraid I don't know that one.

...

Posted by Fitsy (from Hayesville, NC) on February 14, 2008 at 2:44 PM:

Thanks anyway!
