This is my first time of growing this plant. I received a plant from my wife's friend in the early fall of last year. I planted it just about the time it was going to seed. I collected the seeds and stored them through the winter. I cut the stalks of the plant down to about 4 inches from the ground in late to mid-January this year. I planted the seeds in several containers in mid-March. They all came up. I have now transferred the small seedlings from their cup containers to larger pots. I used a mixture of mulch, topsoil and a small amount of blood meal mixed into the soil and mulch.They seem to be taking off in the larger pots. I will probably transfer them permanently into the ground in mid to late May. Oh by the way, the original plant that I received last fall is now coming back. I noticed two small green shoots right next to the dead stalk of the plant.

This plant definitely needs a couple of seasons to start reaching its full potential . I purchased a one gallon plant from a nursery in Goldthwaite TX on my way home from a business trip in Amarillo it has been three years and only now are the stalks emerging thick and tall. the first couple of years were a teaser I guess because this year it looks like it is going to put on a show !

I bought my hibiscus coccineus early last summer and planted it near my pond. In early winter I poured one bag of mulch over the base of the plant. I am thrilled to see strong growth this spring on the plant being that I am in zone 5b and the plant is only supposed to be hardy to zone 6. That being said it was a mild winter. Regardless it is a beautiful plant.

I gave my Mom a plant in 2008. Her landscaping guy accidentally "whacked" it off at the ground, but it grew back! This past year, it reached 9 feet! She had at least a dozen blooms and she saved me the seed pods. I have one as well and it's doing well; bloomed for me this year for the first time. It's such a lovely color. Everyone should have one!

This plant gets bigger and has more blooms every year. It has spread and grown so well since the first planting 4-5 years ago that I had to cut it back substantially during the blooming season this year. I normally cut it back to the ground around Halloween. Flowers bloom in June. I do very little upkeep and it thrives. It gets full sun and mostly rainwater here in Atlanta. I don't fertilize. I haven't covered it during the winter freezes. I spray for bugs when I notice the leaves are holey. The blooms are the size of dinner plates and very impressive. I have 2 kinds planted--one blooms a deep red and the other a dark pink.

IS THERE REALLY A RED VARIETY?
In my experience, the red variety is more of an orange color. However, in many of these DG images the flowers appear to be magenta. Does hibiscus coccineus actually come in a magenta color or even a true, non-orange-ish red? I have both the "red" and white varieties which I grew easily from seeds.

I got this plant as a gift last year, and was terribly disappointed when it "died" in the Fall. Imagine my disbelief, when I saw the green coming up, the following Spring. I see other comments here, that say their plants stay and grow. Mine gets about 4'-5' tall, and is very pretty. I just wish it would not die down completely. My son, who gave me the plant, has one of his own and it does the same thing. The leaves, turn with the trees, and have very attractive coloring. I did not water, except occasionally, during the hottest part of the year.
My Texas Star has been an impressive attention getter. Love it, and how FAST it grows. Volunteer sister plants surrounded it after the first season, but in the 3 and 4th season the surrounding plants have been only miniature versions of the original one we purchased in Austin. We're talking short (18") stalks, miniature (2") leaves, and only 3-inch blossoms. The original plant was planted close to a large window where I can enjoy it, but of course I don't see the little ones from inside because they are so near the ground. Only the original plant amidst those still grows taller than the house; new volunteers are all miniatures. What happened to the others??? Could fire ant granules have stunted their growth? Or some other chemical from the exterminator we contract for quarterly pest maintenance?

When I was a young child in 1951, my family vacationed in southern Florida. We saw these tall, stalky plants with brilliant red flowers. They were growling wild on the sides of the roads. My mother had to have some. My dad pulled up a handful, and we took them back home to Charlotte, North Carolina. He planted them at the corners of our new house around front. My parents left their home for a retirement community in 2000. Over the nearly fifty years those beautiful tall flowers had spread all around the foundation of their home and were absolutely stunning when in bloom every year. Many people stopped to ask what they were.

In its native habitat Star Hibiscus tends to be found along creekbeds, swampy areas, and in ditches. Yes it can go drier...sometimes. If you are in the deep south/eastern seaboard or parts of the west coast where you get regular rains, or if you water a lot anywhere, it will seem like a great plant for "regular" flowerbeds. However if you live in a dry climate/don't water much you will probably want to plant it where it gets more water, like by the ac, or in your water gardens, for best effect. To effect, one of mine in a bed that gets watered every two weeks grows to 3' tall and blooms sparcely, one that grew in a naturally low area with runoff from the neighbors irragation grew to 6' feet and bloomed profusely, the ones I have in 10 gallon pots in my water gardens easily grow 8' and bloom extremely profusely.
Thats in dry central Texas, in wetter East Texas I have seen unwatered specimens in a friends yard that were 6' tall. So, as always your individual climate will effect your outcome with the plants.
Beautiful red flowers, but the foliage is nice too. The foliage will flush red in cool weather, especially in water/bog gardens.

I have two big plants. They live on grey water from the house (all my sinks and washbasins drain into one pipe for use in the garden, and the lavatories, bidets etc drain into a septic tank).
They are in constant water, full sun and have reached about 9 feet with plenty of side shoots producing great flowers.
I normally cut back half the stems when they are about 2 feet high, otherwise they look rather ragged. This allows about 5 stems to reach full height and the others bush out below them to fill in the space.
A definate winner if you have plenty of water and space.
I did grow a couple of these plants in pots, but they never looked as spectacular as in the ground.

My law enforcement buddies saw this plant and nearly went beserk as it appears to be of the hemp family.
Unfortunately,my mother plant grew weell until this June when it suddenly started to whither on both stalks(about 3ft high) She had plenty of water and was not root bound in her pot. I soaked her in fungicide as recommended by the hibiscus folks and then took the plant out of the pot and soaked the root ball. in C triple action 20(5% mix). I replanted and hope for the best.
BUT, the seeds she produced are growing rapidly and well. I just wonder if any one else has had a spot of this sudden droop and rot?

My plants are growing at my pond edge. When the summer rains come, the pond level will be lapping at their feet. That's OK - they are perfectly happy growing in water up to 18". In the winter, they die back despite our moderate winter temperatures in Florida. Once Spring arrives, they begin to push up from the earth to begin blooming in late June. They will continue blooming their hearts out all summer and fall. I waited this year until they were approx. 12-16" high and then I cut them back to encourage branching which results in more flowers. I put the thicker stem cuttings into the wet sand where they would get some shade and they rooted quickly. Then I transplanted them to sunny locations.
Over the winter, I started 100 plants from seed. They are very easy to start from seed if you barely cover the seeds with soil and keep it moist. I started them in late November and put them out in the sun as soon as they had 4 permanent leaves. When the outdoor temps got down to 50 degrees or less, I brought them inside. Fortunately, the Florida winters are mild and I was usually able to get them back outdoors the next day and we didn't have too many cold nights. Keep them slightly moist and in the sun to produce strong plants.

Because I have a wildlife habitat- I tried this plant in my bog garden first and the next year I planted the harvested seeds in a pot for one of my regular ponds. It has done so well (both over-wintered outside) that I tried some seeds in regular soil by a dead tree used for bird feeding. The plants are all blooming beautifully in all locations and seem happy. This years seeds will be given out as little extras in Christmas cards to friends.

I'm tempted to see if this will overwinter here in zone 5 but don't want to risk killing this beautiful plant. I kept my "Great Red" indoors in a container through the winter months and set it out on the back porch in summer. I purchased the plant at Monticello in a four inch pot almost one year ago.
This can grow into a very large plant. My cousin in Ms has one so large it covers the storage shed- and gets lovelier every year. I broght a very small seedling home to East Texas 3 years ago, and every year it gets more beautiful. One of the nursery men told me it is called the Confederate Texas Star--guess because the leaves have 5 points like the lone star of texas-

I was given seed for this plant about three years ago at a Native Plant Synposium in Atlanta, Georgia. I got six plants from the seed, planted them in the red clay there, in an azalea border that got lots of water, and they all grew, but very slowly.
When I moved to Florida I brought one plant with me in a pot, and it was planted in a party shady, raised border last fall. It must like it here because it recently bloomed for the first time--four strikingly huge, red flowers that eventually turned into bright green pods, and when the pods turned brown I collected the seed. I'll be putting the seed in a pot very soon to start more plants.
Here in Northcentral Florida, zone 8b, I see this plant mostly growing in water gardens, where it can attain great height. Mine is only about five feet tall at about three years old in a regular flower border, but I've seen one here in a tub in a water garden with long fin koi that must be eight or ten feet tall--it's easily the tallest plant in the pond.
October 6, 2003: I now have over a dozen seedlings growing in pots. Not sure how I will overwinter them--still in their pots surrounded and covered by mulch, perhaps. Anyone have any suggestions as to how to overwinter these seedlings?

I have 4 hibiscus trees. Two are blue also called rose of sharon. These have a different leaf, sort of like a leaf of a mosquito bush. The other is a double yellow and the last is called a lipstick hisbiscus. They grow beautifully and here in Tucson they are easily purchased at any nursery in April.The three bushes I have are a red, an orange with red throats, and a yellow with red throats. They seem do do better in full sun but with our heat they do get stressed. I prune them down about 2/3s and they come right back. I also leave only 2 buds on each branch so the flowers will be bigger.I have learned however that you have to be carefull not to overwater these as the leaves will yellow and start to fall as will the buds.

Planted in fall last year (nursery specimen). New growth did not appear until early May 2003. Plant is approx. 6 feet tall and 3 feet wide with several "stalks" emerging from base. Buds form in clusters at the top of each. Leaves are similar to a hand that are deep green with 6-7 seraded fingers. Does well in partial shade to full sun. A wonderful specimen to add a different "flavor" to your flower bed or garden.

I have had this plant for two years now and each year it is more beautifl than the last. It loves to be packed with other plants. I take the seeds from the pods when the pods begin to open and have started several plants that way. It seems like the plant needs a couple years to bloom. I planted two seeds last year and they have come up, but very slow. The parent plant is almost 5 feet tall now, while the new plants are only 2 feet tall. I will try to keep you abreast of the growth. I live on the coast in NC.
