I been reading the info about each double and it seems like doubles have better bushes and grow better than a lot of the single varieties. Do you think the double gene is giving vigor and strength to these cv's ?

Kerry, if that is true (not sure which varieties you are thinking of) it is balanced by the likelihood of bud drop in hot weather by doubles. That might not be such a big problem for indoor or protected growing of the type I think you do but doubles also have trouble forming buds in lower light situations. They bloom great in perfect conditions and sometimes during the spring or fall these conditions occur in many places but singles are more likely to do well during more stressful times of year like mid-summer.

Thanks for the info , I did not know all doubles had bud drop in hot weather. Is H. rosa Sinensis the same ? IMO the bushes of the doubles you offer seem HUGE ! and so does the leaves. |

Is it possible to have a double hib with double styles, ovaries, and receptacles coming from one fat stem or am I crazy? I have been watching what appears to be 2 of the above wrapped around one set of petals on one stem. I don’t want to break it off but if feel s that way as well. It looks like it will open in the next day or 2. It is Heavy Metal which has set a seed pod in the past. I want to try and pollinate it with Creme de Cacao or Gator Pride which look like the will be opening the same days. Any advice to a rookie from a veteran on successful pollinating in july? I am in san diego about 5 miles off the coast.
Thanks for any input
I will post a picture when I get home tonight

Very interesting, hot weather can make flowers develop in werid ways. I would really like to see a picture of that. It is entirely possible to get seedpods in July. I got several seedpods last summer from Belle du Jour and Saffron. The key for me was to only give them 1-2 hours of morning sun, and lots of shade. Under those conditions seed pods did develop. Hope that helps  |

Thanks for the input. Is the shade important for the day of pollinating or for the entire extent of the pod development? I will post a picture of it tonight. Thanks

Shade and overcast weather allows the stigmas to stay sticky and therefore form pollen tubes to the ovaries allowing them to be fertilized. In hot weather these pads tend to dry, so shade increases your chance of getting viable seed. If your plants are in pots you could also bring them indoors to try and get seed. I was able to get alot of viable seed this winter indoors. Hope this helps |

I have been anxiously awaiting the double wide bloom but found it on the ground this morning. I sliced it open and it was as described above, double styles, ovaries, and receptacles coming from one fat stem. I took pictures but had to get to work, I will post them this weekend.
Is this a common occurrence?

Hi Stavo, that's an interesting exploration - dissecting the bud!
How hot is it where you are? In high heat doubles such as Magnifique will often drop their buds before opening.
The other problem is an insect called thrips. If thrips lay their eggs in a hibiscus bud the bud will turn rotten looking (sometimes) and then fall off shortly before it would have opened. You can read more about thrips in the forum and in the care section of the website.

Bummer that it fell off  It sounds like a conjoined twin, and would have been so interesting to see. But I'm looking forward to the pics of the dissected bud. |

Ahh, I didn't see your earlier post above. Out of probably millions of hibiscus flowers I have seen, only a few were this type. They do sometimes open, and look very cute together.
