This is my October 2006 update.
“Possible tetraploid” acicularis used as the mother:
2004 R-15 as pollen parent.
There are 6 surviving plants. Only the one mentioned earlier in this thread has flowered. The pollination attempt with Carefree Sunshine failed. Also, no open pollinated hips were produced. I assume that I tried using the (acicularis X R-15) pollen on other plants, but I did not find any successful hips. When this plant bloomed, there was quite a wet spell, this may be the reason for the lack of hip set both as mother as as father.
2004 (Hansa X OP) as pollen parent.
There are 10 surviving plants. 2 flowered.
One flowered in early June and had pink, semi-double flowers. No opened pollinated hips were found.
The second formed three hips, but no information is available concerning the characteristics of the flowers.

There are also 10 surviving plants when the pollen was a mixture of Agnes pollen and acicularis pollen. Only one flowered. It formed large, pink, semi-double blooms in late May. No open pollinated hips were found.
