I have been collecting hips from open pollenated flowers in my garden and found that the seeds of ‘Stanwell Pertpetual’ (a R.spinosisimma x ) have germinated very well - I can tell as they all have the unusual leaf and prickle formation.
Does anyone else us this parent? What sort of variation do you get? All my seedlings have the ‘fern’ leaf and prickles rather than thorns. I have yet to see a flower.
I have only done my first cross for roses this year (Bloomfield Dainty x Whiskey Mac)and am keen to try and cross with R.roxbughii (which I have a cutting of the double form). However this plant does not seem to want to flower! Does anyone grow the roxbughii spp. and when do they normally flower? I am in Australia so a season is most relevant rather than a month.
