Morden Sunrise is one of my favorite hardy shrubs. It has such a beautiful, simple blossom; Sunrise was a very apt name. There are a few issues that you should know before you chose this cultivar:

1) In the twin cities area of MN we have a species of blackspot that defoliates Morden Sunrise before any of my other roses. In fact, it acts as an early indicator plant for the garden. Depending on your area of the country, you may have to spray diligently to keep any of the beautiful dark green foliage after July.

2) Though Morden Sunrise is definitely crown hardy in zone 4, in 3 winters not a single cane survived the winter; however this cultivar is very vigorous and threw surprisingly thick canes and was in bloom with the rest of the garden, so don't panic in the spring if you have to prune to the ground.

I am in zone 4b/5a and my Morden sunrise also dies to the ground every winter but comes back to be about a 2.5x2.5 feet bush. Also here in northeast Iowa it also suffers horridly from black spot almost every spring and early summer during the rainy periods though the plant doesn’t seem to be bothered by this much.

I have renewed my premium membership, but I still can't see rose lineages.

I ordered this rose two years ago and I could not be more pleased. It has a wonderfully fruity fragrance, It is beautiful both at exhibition stage and when it is fully open. The petals are of particularly good substance. This rose looks particularly vibrant floated in a black glazed bowl (two years ago she received a blue in that particular class)

I grow it in Minnesota (edge of zone 4 / 3), on its own root in a 14" square "ornimental" plastic pot, where it seems quite happy. I overwinter my tender roses in an insulated shed which was supposed to be kept between 34 and 38 degrees by an agricultural thermostatically controlled electric heater, but last winter the heater failed and the shed reached a low of -15F on a morning where we had -25 ambient. She came out of the shed with only minor damage and has recovered beautifully, so I would disagree with the assessment of her cold hardiness.

Where did you get Rosemary Harkness on its own root? I prefer own root, when possible.
Thanks!

I have found a problem in My Wish List:


If you select List Order = Nursery, the links of the [+] do not resolve to anything.  It looks like the problem is that the business type check boxes are empty, and I cannot seem to make them stick past the screen.
