I've noticed that the blooms on Cosmic Gold open much later or take longer to open than most cultivars. But the flower lasts well into the next day even in the heat. Also this is probably the only one so far that hasn't lost a lot of buds going from the mild climate of San Diego to the hot climate of Houston.

Interestingly, Cindy just told me this morning that 5 Cosmic Gold blooms were still open from the Saturday Open House. That would make them open for 3 days and still open at the beginning of the 4th day. These are blooms picked as buds about to open Saturday morning and then sitting on a table in the shade since then.

Cool weather blooms on Cosmic Gold, much larger size and better form than summer blooms. This one really loves more mild temperatures!
(This saves you the trouble of moving the pics from Nov flower photos of the day, Charlie)

I've noticed the same thing, Chris. Mild weather allows the full size and beauty of Cosmic Gold to show itself. Thanks for posting it here!

Its amazing how different the first bloom I had in mid summer was. It was pretty, but wasn't a wow bloom for me. This cool weather bloom is really something and I just measured it, about 9 inches! Most other varieties bloom smaller in cooler weather, but look like CG breaks the mold. Really is a special one, thanks for introducing this beauty Charlie!  I am sure we will be seeing some of its offspring in the store next year? |

What a difference! It's been a good parent for me so far, often yielding very large offspring.

Charlie, not sure if i should post this here, however my cosmic gold was going gang busters with several blooms on at one time. all of a sudden the new buds, that are about 3/4 inch long, turn yellow and drop off. i thought possibly a thrip, but i have never seen one here. i have examined the plant with 20 x mag and a bright light and see nothing. any ideas?
louis
btw, none of the other plants are affected

It sounds like your Cosmic Gold was subjected to some sort of environmental change it didn't like. Is it by a door to your sun room, or maybe a crack where a draft can get in? Ive observed the same thing when conditions changed quickly with my plants. Seems like some CVs are more prone to sudden changes than others. Hopefully it fixes its self soon!

Hmm, that's kind of surprising. 90 percent of the time it's insects - either thrips or hibiscus gall midge. That would still be my guess. But as Chris suggested cold drafts or perhaps several days of solid clouds could do it, also. Thrips are almost never seen as adults except inside open flowers and gall midge are best seen as yellow worms inside of rotten buds. I would try a light misting of spinosad over the tops and buds of Cosmic Gold and any nearby hibiscus with buds. Sometimes these problems come and go and we never know what caused it.

Hi Louis,
Just another thought on your bud dropping. Is there a chance that your Cosmic Gold got a little too dry and got water stressed especially since you stated that your sun room can get quite warm even at this time of year? Warm to hot temperatures and water stress caused a few of mine to drop some buds this past summer. I didn't have thrips or gall midge in my greenhouse so I've eliminated those as the cause for mine. Some of mine also seem more prone to bud dropping from any kind of stress or change.

I would like to do a mass planting of Cosmic Gold this spring.  |

A mass planting of Cosmic Gold could be spectacular. Just curious when your plant reached blooming stage? I'm not certain but Cosmic Gold has shown some tendency toward smaller, less attractive flowers in the hot months and reserve the huge, beautifully formed flowers for milder times. Has anyone else noticed that or had great blooms in mid-summer?

I can tell you my 4 inch started blooming when it was about 9 inches tall, really spectacular considering it has huge blooms on a small plant. I have to agree with you about the cooler weather blooms. In the summer they are smaller, but still pretty flowers. However, the blooms I have been getting this winter have been fantastic, huge ruffly blooms that come in shades of gold and tangerine. Its interesting that the blooms are so much nicer in cooler weather, when most varieties it seems as though the opposite is true, the warm weather is required for huge blooms. I wonder if any of CG's offspring also show this trait? I am all for great cool weather bloomers these days Robin hood produces small dark blooms in cool weather, and seems to be pumping out the blooms despite the lack of sun! In fact it seems as though sun is required for initiating blooming, but the plants keep going for several months even when they aren't getting sun. Good trait to have if you are ever going to sell those Christmas hibiscus |
