Gardeners' Notes:

I bought Sweetness last year. I'm in Canadian zone 4b (Quebec city). The bush survived the winter with minimal winter protection : good point. But the leaves are attacked by black spot all the time (last year and this year too). The color of the rose is beautiful, but I find that the petals rapidely deteriorating, specially on the edges. This year, 4 branches grow way over the bushy leaves with flowers on top by bouquets of 4-5 flowers, don't look very beautiful. I try to find a consolation with the perfume which is really sweet.

I purchased three of these bare root roses from Jackson & Perkins in mid-April 2012, along with 10 other varieties. It was the first to blossom (c. 12 June 2012). All three plants are continuing to do very well here in southcentral Pennsylvania, about 45 northwest of Harrisburg.

I purchased Sweetness from Jackson & Perkins this season as a bareroot. In just 3 months sweetness has grow to over 2feet tall. and has had 3 flushes. It is a 2 tone rose, lavendar with a lighter shade underside (pink ).

This rose has a outstanding sweet smell, true to its name. But, this sweet smell seems to fade as the rose matures on the bush. If cut, the smell will fade within the first day, but the rose will stay for approx 3days in the vase with just a slight scent. Now keep in mind that my sweetness is just a few months old, iam hoping that as the plant matures it will hold onto is smell longer, and also last longer in the vase.

I have had no problems with disease, no blackspot, or mildew. This is a very aggressive grower and a must for any garden. I will report next season on sweetness progress after the zone 6 winter.


UPDATE: April 8th 2011: Sweetness is now 3 seasons old, she does last much longer in the vase approx 5-7days and the scent last longer also. Beautiful high centered form, many petals, thick arching canes. A must have,will send sweet scent all over the garden!!!!
