What a pretty thing this is when its in full bloom. I grew them from seed, and they have become attractive small shrubs with an open habit in my school garden. The yellow flowers are quite showy in midspring, and numerous hips are forming as I write this. Sadly it only blooms once a year, but it also doesn't take over the garden later on like R. multiflora would if it could, as it is a major pest along our roadsides. It does have lots of small thorns on the stems, which probably help deter deer from bothering it, at least in my experience so far they do ignore it. It also blooms well before blackspot and other rose diseases get going in our humid weather, and I haven't even noticed if gets blackspot to be truthful. In any case, it is a reliable early bloomer which does well without the fussing modern roses often seem to need in our climate. Sometimes simpler is better.
I'm a high school biology teacher with a passionate interest in plants for as long as I can remember. I have two horticulture degrees, BS and Ph.D. from Cornell and I've worked at the New York Botanical Garden in the past. My plant interests are quite simple: everything! Still, I have a special affection for South African plants, including, of course, pelargoniums (aka "geraniums").
