I have just collected at least 100 seeds from my hardy hibiscus 'Summer Storm'. Has anyone grown hibiscus from seed? Will it come true. I do not know if this is a hybrid, or just a named variety gleaned from selected seed.
I am still going to start a few and see what happens. I would still gain from your experience, if you have grown this or a similar one from seed. Thank you.
Thanks, Blomma! I will let you know what happens. I will probably do several different methods and see which one germinates first. I think, since the seeds are fresh and the weather is warm, that they will germinate quickly...at least I am hoping...
I do have a good amount of seeds. Then I will rogue out any plants that have green leaves, as this plant has beautiful maroon foliage. I won't care what color the flowers are as they are all beautiful.
Evelyn, I also grew about 50 this past season also with the Deno method. And they did very well. The only problem I have had this year I have not been able to collect any seeds. Have know idea why. But the ones that have bloomed their first year have done very well. And I can't tell much difference in the blooms from the store bought ones. Good luck to you.
@Hibiscusmile: Your method is what I was hoping to try--sowing directly into ground. I just pulled about 20 pods off my bush and each had maybe 50 seeds? I haven't counted but I have a LOT of seeds, maybe 400? And fresh, just harvested today. So I was thinking to start it in about a 4' square area.. Then transplanting next year.. Temps here have been mid seventies and low eighties for two weeks. Since it is midstate Georgia, it could tip high again. I don't expect freezing for awhile, but I haven't looked it up yet. So I'm thinking take my chances, keep soil moist, then mulch heavily with pinestraw when freeze is expected. Last year I tried to grow some daylilies from seed and was very disappointed when not one came up. I think I left them in fridge too long and they weren't in napkin and were too wet. Ie, turned to mush. I am trying some daylilies again using the baggie with paper towel and I added hydrogen peroxide, 1/10 diluted to the paper towels to keep down fungus etc. But, I would like to plant the hibiscus directly in ground because I have so many. Can anyone give me some pointers on how to make this work better?
i winter sowed some last season and one plant survived , but to my great surprise 2 plants of the white came up in my full sun garden bed next to the establish plant. Next year they may come back and flower.These are the colors I have.
Evelyn, I put several in trays on heat like a week ago and they have already germinated. I moved them outside to the unheated greenhouse and they seem quite happy there in 5" pots. Mine are "Luna White". I hope they make it through the winter, the greenhouse stays pretty warm so I think they have a chance.
Well, it looks like the weather is going to hold so I'm going to put the three "Luna white" in the ground. I know from past experience that they have a tap root and I don't think it's wise to leave them in small pots any longer than necessary. On the whole I think hardy hibiscus is best planted in ground to begin with. I haven't had much luck either way so we'll see. If these die I'll probably try the Deno method and plant them out as soon as they sprout. They are worth some effort though, they are easy care once established and are really lovely plants.
That's good to know as I put mine in 4" pots and I worry about stunting their growth. I have had trouble with that before with tall "tap" root type plants. I just won't leave them in there too long, I should be able to get them in ground next month, the weather is already warming here.
We are staying in the 50's during the days and 30's at night. I checked my coldframe today and a lot of things didn't survive the last freeze. Maybe some will come back from the roots, but I missed a few succulents when I was arranging the greenhouse and I thought the cold frame would be warm enough. I was wrong...
To give a short description, Dr. Deno was a retired chemist in Pennsylvania, who became interested in how seeds sprout. He devoted an amazing amount of time (and $ too I am sure) to planting seeds of every species he could get his hands on, in different conditions. He felt that the process of germination was simply a series of chemical reactions, and could be approached scientifically. Nobody wanted to publish his research, so he self-published a book, and then 2 supplements. This was before internet publishing(1993,1996, 1998). He sold individual copies to people using the mail. When he got old, he donated the books to the public domain, and they are now ensconced in the government archives. You can download them off the internet for free, and either have them in your computer or print them out. It is a truly amazing amount of information for seed sprouters. But beware, it is a lot of info with a lot of abbreviations and not very readable.
Printed out it's about 1 inch thick...I was fortunate to have one of my friends here at Dave's send me a copy... I have found many seeds will start using my method (homemade seed mix of peat and peralite, lights and love...lol). But am glad to have the info for those hard to germinate goodies... Another great souce is: backyardgardener.com. This is Thompson and Morgan Seed starting guide, their catalog also lists great info. I get these catalogs and have kept them for more than 10 years now as the info is invaluable...
I started several varieties of Hibiscus last winter and most that sprouted stated within 4-6 days using my traditional method. I will have a patch of H. coccineus Red if they make it thru the winter...they got planted in the border late last summer. So far they've had a nice blanket of snow on them all winter...
We only get snow about every 5 or 6 years and then it doesn't last and there is never much. ( Thankfully)
Today, I am going to rearrange the cold frame. I know that february and March will have some very cold nights, so I think I will take some plants indoors and then use the space for seed sowing.
I will try the Deno Method. I have some seeds for goldfish plant that i really want to do well. I love to grow out of the ordinary things from seed. Here's hoping this method works.
