Last season I did not soak my seeds, instead I put them on sand that was wetted with a bromelain solution. Although the germination was enough to keep me busy, there were some batches that did not germinate at all. This year I put my seeds in a regular Bromelain soak, (starting on March 30), for from 3 to 5 days. I used the longer than 2 day soaks because the containers were kept in an unheated sunroom. I figure that not much “action” happened at night when the temperatures were probably in the 30s.
The first germination occurred today. It was an open pollinated seed of a 1998 open pollinated seedling of Elmira ('Elmira' Rose ) . This last summer was the first year that I remembering it flowering, much less setting hips.
Elmira is a diploid rugosa-chinesis cross similar to Bonavista. I had distributed open pollinated seeds of Bonavista in previous years. Does anyone have anything to report about them?
For me the Bonavista crosses have been interesting for several reason. They have been both winter hardy and essentially disease free. Also they have very good repeat bloom and appear to accept/give pollen from/to both diploid and tetraploid roses. If you use your browzers find command with Bonavista, you can see what recent offspring I have obtained:
