Species Cross.  

Predicted: Mauve.  Arno Schlick (2007).  

This hybrid stellata mirifica from a May 2007 cross seems for sure not to be a selfing, as the leaflets of the seedling show strong multiflora influence (see fotos) so there can be nearly no doubt that its a true hybrid.
After the few existing Louis Lens Rosa stellata var. mirifica F1 hybrids, it should be now one of the very few new ones, if not the first after Louis Lens works.
Good indicators for observing a true hybrid here are also the stems of the leaflets, they are much longer than it is for the typical leaves of stellata mirifica, especially in the picture of the 5th compound leaf (close look).
You can additionally see even the increasing length of the last middle stem of the middle leaflet on every one of the compound leaves, from the first true leaf up to the 5th true leaf and further!
The fotos show that the leaf geometry of multiflora is more developed in this stage as the typical characters of the leaves of Rosa stellata var. mirifica.
And what is also of interest: still at that stage of the 6th true compound leaf after growing for over a month the compound leaves consist of only 3 leaflets!
Again and again I treated the stellata mirifica hips during pollination with a cooling / heating method which I had developed since 2006. ... So out of a dozen hips I got these 9 seeds (which is a very good output, normally one gets much less good seed material and the most of them are degenerated). This year, in 2010, I tried the method again - a bit simplified and adjusted to lots of hips as I pollinated over 150 of them on stellata mirifica this year. With some crosses it seems to work again, as one can already now, after 2 to 4 weeks after pollination, see some seeds from the upper side and in the forming hips! I tried out odd multiflora hybrids, odd rugosa hybrids and odd china hybrids - and some pure wild species as well. The selfmade scale at the top marks 1 cm (divided in 2 parts by a small point in the middle).

Some thoughts for the next couple of years: The colour and shape of the flowers will be quite interesting, because of the mauve/mauve background of both individuals!
My idea back in 2007 was also to cross the two individuals because of the colouring!
And: so far no mildew occured, which is pretty unusual for Veilchenblau seedlings.
I think here is at least some powdery mildew resistancy that is passed through to the offspring by mirifica!

The crossing is first documented here in the internet:

And I will do entries here on HMF in the journal for this rose (see link in the middle at the top of the page).
