I am growing several of the Oso Easy roses by Proven Winners. They are growing like mad and my Paprika variety is blooming its head off. I will post about Fragrant Spreader and Strawberry Crush as they bloom. This is a very good ground cover rose. It reaches mature height in one season is hardy to zone 5. I fertilize in the Spring with Espoma Rose Tone and my gardens receive mushroom compost at that time also.
If you need to cover a steep slope or similar situation, give these Oso Easy roses a try. I will add that they have spread by layering after being in the ground for only one season. Wherever they had been covered with heavy mulch, they set down roots. They do not require a lot of watering.
( Above you can see Oso Easy Fragrant Spreader. It is a bit bigger now as this was taken about a week ago. You can also see how it layered and formed a new plant. It has a lot of blooms on it and I will get pictures when it blooms.) My experience is they get larger than the 24″ suggested. I would say more like 36 and more if it layers.
