Hello together!

I have red a lot now of different Poncirus types. Some are more interesting for breeding frost hardy hybrids than others. I red for instance that the famous Dr. Brown from Texas struggeled with polyembryony. But I could see just recently that a tree in Mainz (Germany) has close to 100% monoembryonic seeds. Or I red about a fast Trifoliata, about more or less frost hardy ones, some with large and some with small flowers etc. And aside from these well known varieties, there might be Poncirus trees with more or less fragrance, fast and slow growing ones, some that are more deciduous than others, some that grow early in spring and others that grow later, some with a lot of pulp others with less, some with a lot of resin others with less and so forth.
Wouldn't it be great if we could gather here which varieties we have so that we can more easily exchange them for the sake of hybridizing? Does somebody want to share what he has access to? If so, please give as much information of your tree as possible (flagrance, pulp, taste, hardyness...).

Yours,

Till

P.S.: I have (officially!) pollinated the Poncirus tree of Mainz botanical garden with Moro and Vainiglia Sanguigno pollen. I could not wait until my tree is blooming.

Till, here is my favorite, one with mighty thorns, Bull's Horn.
I'll update that topic later.

Till this is an excellent idea! Please keep us informed on your hybrid attempts also

And the variegated trifoliata & flying dragon.

it would be nice to see everyone's PT to see how they differ from each other.

I took a couple photos of my PT flowers. My PT flowers don't have much fragrance to them.....you'll need to get 3 to 4 cm from them to smell them.

Poncirus from NC, a large flower type

bussone,
Yes, I have a few 1 year old seedlings. All seedlings looks similar.

Thank you to all of you for the nice pictures and information! I see you have interesting plants. I find the bullhorn very cool and also that with the large flowers. May others join in on this post so that we have a good overview what's up in the Poncirus world.

I can offer (or will probably get soon) the variety of the botanical garden in Mainz which is a Poncirus tree with big flowers without much fragrance, strongly smelling fruits (3mm skin, a lot of seeds, taste sour not really bitter, but a lot of resin that glues on your touth where it is bitter) and mostly monoembryonic seeds. My own Poncirus trees have not yet bloomed.

A short update from my crossings: I have made Meyer x Moro (in hope of early blooming offspring with zygotic seeds), Moro x Poncirus, Poncirus x Moro, Poncirus x Vainiglia Sanguigno, Meyer x Poncirus (mother plants first). Fruits are forming. Now I have to wait for the seeds. And I am ging to do other crossings this year.
