It bloomed again already. Its so cute, lol.
That is cute, Michael. Bonica should also give it some decent health and vigor. Congratulations!
Thanks. I am happily surprised with it. I am not sure if it will be the plant architecture I want, but I can always cross it one more time for what I want. The amazing thing about this one is that the stripes are on both sides. I dont like it when the stripes are on the face only =/
That opens greater possibilities, though. Stripes only on the face means it should be a real bicolor.
That is a really neat stripe. Let’s hope it has good fertility, architecture etc. sounds like it is free with the rebloom.
I think the rebloom comes from Shadow Dancer. Bonica blooms in waves here. I guess the species part of Bonica is a perpetual bloomer, but I dont think that carried over too much. Shadow Dancer blooms continuously here by forever branching out in this awkward pattern.
That’s an interesting cross.
One of the wrapped cuttings which sat for months this year has shown itself to be a Shadow Dancer. It’s still in a 16 oz. cup.
I might be able to squeeze it into a small Flat Rate Priority Box should anyone in the US be interested.

Michael,
That is simply perfection. What a beauty. It reminds me of Astronomia in its’ simplicity and appeal.
This is the Bonica X Elara seedling in bloom, flowers have a slight yellow tinge to them and plant growth is similar to Bonica.

Wow Warren! Your double white seedling of ‘Bonica’ is gorgeous!! It looks like it has dark foliage to contrast especially nicely with the clear white blooms!
My hybrid still has all of its foliage on it, without a spot of disease. What a weirdo, lol. Its December! It is a cute bugger. I plan on crossing it with Carefree Mavel x Cherry Meidiland, as well as Birthday Girl 
I plan to breed a rain-resistant, sun-resistant, aesthetic, disease resistant striper! I am so sick of the sripes too closely related to minis. They always have blackspot and awkward growth x_X
That’s for sure. This is what a tray full of OP ‘Bonica’ seedlings look like here (just before they were all dedicated to that big rosarium in the sky):

Plenty of water… no excuses. Just plain awful.
Yeah, I had to cull a lot of Bonica babies, but there is obviously potential.
To much water Simon or is it the part of Tasmania you live in(HeHeHe)
What ever it is, Dave, ‘Bonica’ is getting shovelled this winter. I would like to play with ‘Swany’ instead.
…or Swany’s sister, Alba Meidiland: 'Meidiland Alba' Rose
Dunno which offers more to breeders.
I have only kept 2 Bonica seedlings, one has bright red blooms and the other, this white. You have to wonder why Bonica has 80+ offspring and Swany has very low numbers. Fertility problem? Health problems? you have to ask yourself. I will admit there were alot more than 2 Bonic seedlings which I bred, but most were not worthy of being kept. Last year I used a rose in my breeding which has unbelievable health, but when crossed with multiple other healthy parents , most offspring developed PM . This was quite concerning for me as all offspring developed very colourful offspring with reasonable form. Alot were disgarded.
I think Bonica will produce good offspring , but you have to match it up to suitable pollenators. Being a Triploid it probably has a 2 + 1 config, fertilizing it with tetraploid pollen would result in tetraploid offspring. I would n’t use the pollen to pollenate modern tetra’s, because you end up in that vicious triploid cycle. Just my opinion.
Swany/ Alba Meidiland = Sempervirens x Mademoiselle Marthe Carron
(Sempervirens x Mademoiselle Marthe Carron) x Picasso = Bonica 82
That these two have few descendants might mean there are fertility issues (we don’t know how long they tried before Bonica 82 turned up) or it could just mean that nobody has bothered using them because Bonica 82 is such an easy seed parent. Bonica 82 is fertile with the same pedigree so chances are good that fertile progeny might be possible with some effort.
Interestingly a reference on HMF states that sempervirens can have a ploidy of 14 and 28. The triploidy in Swany might have come from the use of a tetraploid version of sempervirens.
What I do ask myself is that if ( Sempervirens x Mademoiselle Marthe Carron) x Picasso can create Bonica 82, what else could (Sempervirens x Mademoiselle Marthe Carron) x ? yield? Given that Bonica 82 completely defoliates here and every seedling I have ever got from it, OP or planned cross, has mildewed badly I’m keen to explore the possibilities from further up the family tree. The Bonica 82 x Immensee seedling I mentioned earlier had a beautiful flower but it has been discarded because of mildew issues too. This reminds me of 0-47-19 a little. OP 0-47-19 seeds were sent here and I grew a batch of seedlings. Most of them mildewed badly. I have only one left. OP Floradora seeds were sent over and I have none of these left because they got mildew so badly that I didn’t need to cull them… Ma Nature took care of that for me. My bet is that the mildew problems in Bonica’s babies came from Picasso in much the same way as the mildew issues in 0-47-19’s babies come from Floradora. Mademoiselle Marthe Carron is basically wichurana so sempervirens x Mademoiselle Marthe Carron is basically a species cross (from within the Synstylae section). Mildew might be an issue here, but I doubt it. Careful selection of pollination partners might be able to fix that but going back and seeing what can be made with Swany or Alba Meidiland might also yield a valuable breeding line free of mildew issues as well. A lot of culling and wasted time might be avoided trying to find that ellusive partner if the issue can be addressed earlier in the pedigree.
A triploid breeding cycle is not all bad. The pollen/ovules they make do not always have a clean 2:1 split. They often make some 2n pollen and some 1n pollen, for example, and can be a useful breeding tool to pair with both diploids and tetraploids. You may get more triploids but they are also a useful bridge in making the jump to tetraploid and useful in pairing with diploids to make diploid breeding lines. Triploids also often possess qualities that are useful in gardens; fewer hips (generalising), self-cleaning, a good compromise in vigour and flowering ability between diploids and tetraploids… etc
idk, I bought Candy Maidiland this year so I’ll find out in the future.
