My Disco Belles are 3-4' and I never pinch. Most of them are pale pink with a deeper pink eye but one of them, a seedling grown from the original one, is a deep pink with bigger flowers and is shorter and later to bloom than the others (it opened its first flower yesterday). It's definitely a good idea to buy Disco Belles in bloom so you can see exactly what you're getting.

My brother walks in the room, says where are you going to put all of these hibiscus and datura seedlings and I tell him, It's not how many there are, it's how many are going to live. If I start with 10 of the same kind, I'm sure to get 2-3. There's just too many things that can go wrong with seedlings, so if I want a plant from seed bad enough I'll order or get enough to ensure I get 1...lol You probably shouldn't have had that compost in for seedlings, and no fertilizer at all until they've got at least their second set of leaves (1st true set) but from the sounds of it, your remanders are strong and doing fine. Use a very little fertilizer at first...as in real diluted, just enough to get them use to it. You'll have to feel your way through as to when to add more as all plants have thresholds for such things. I like researching things but I can't remember how much I fertilized. Though I don't know if that's necessary if you already have compost in your mix. Now, I haven't grown lunars, but I have grown 5+ other kinds. Your roots, I believe, are little tubers and they must stay attached to the neck of the plant when you transplant, much like dahlia's except longer and thinner tubers relative to the plant size. They are stonger than veining type of roots. All my hardy hibiscus shoot straight out, in one direction or another. I expect yours are probably curling around the bottom of the pot and you should have them in ever bigger sized pots. Just keep in mind, a root bound pot means there is so much root in the pot that the water just runs right over the roots and out the bottom, with nothing much to help keep the water near the roots for a long enough time. They will grow much faster in their second year and probably be able to reach full heighth in the third. Albeit those newer kinds of hibiscus (especially to most of us here in Canada)do each have their own characteristics and your own growing environment and care will have a lot to say about how fast they'll grow. But from what I've read and I've read on almost every kind, have the same growth biology...but there are always exceptions to the rules, such as Lord Baltimore and others that can grow pretty tall. - Sandy

The short answer is "No". That said, the Fleming Brothers have developed at least three cultivars that they have patented, or are patenting, that they assert to be hybrids of hardy hibiscus and exotic tropical hibiscus, of the rosa-sinensis complex. However, I have a "backyard hybridizer" friend who seriously questions their claims. That said, I DO have one of these plants, Pink Comet which at least hints at having rosa-sinensis genetic material in its heritage. I have also read that hybrids of rosa-sinensis, and Hibiscus syriacus( The Rose of Sharon)have been created. I have not found them on the market yet, however. DO give it a try! You just MIGHT get fortunate! Subtropical hibiscus, such as Hibiscus grandiflorus of Florida, will cross with certain hardy hibiscus, such as Hibiscus moscheutos. These can be truly spectacular. One such hybrid is Hibiscus 'Moy Grande'. This was developed by a Dr. Moy, of San Antonio if memory serves me right. It is worth obtaining. I can send you seed, if you tell me your name and address.

Hibiscus moscheutos is native to eastern North America as far north as NY and NH.
