Always buy roses on their own roots, as they will be more resistant to disease. You will find them to be hardier and will not lose them to cold weather or animal munching. Considering my knowledge of their performance here, I don’t recommend ‘Simplicity’ or ‘Flower Carpet’. They do not do well in our area. ‘Flower Carpet’ must be covered or protected to survive. We plan to add new roses to the gardens: ‘Hanson’s Yellow’, ‘Henri Martin’, ‘Ballerina’ and ‘Mossman’ are some we are considering.
