I have not seen this rose for sale anywhere since the 90s, but it is now (March 2016) being sold by the dozens by Home Depot. They are being sold in this bizarre little plastic cubes by Vigoro. I think $9.98.

Sunsprinkles is an amazing little yellow rose. It breezed through a zone 6a winter with no winter damage at all. It was one of the first to start blooming and has been in bloom ever since. The heat of the Summer,(90-100f) in full all day sun, didnt' phase it in the least. I've only deadheaded it a couple of times. It doesn't seem to care one way or the other. It's not had a single hint of disease, even when almost all the other roses had black spot.
