I have both the White Meidiland and this Alba Meidiland (yes, they are different roses)! I got them both earlier this summer and they are both doing very well. Alba is completely covered in buds with several blooms open! I first saw them growing locally both as a ground cover and one that had been grown in a pot and was scrambling up the side of a greenhouse because of limited space. They really can spread out and seem to be extremely hardy!

Bought this rose last summer and planted it fall. It has a difficult site with only intermittent sun due to trees but is on the south side of a building. It has bloomed throughout the summer and increased in size but not as I would like. Will probably move to a sunnier site.

Planted in a large pot in shady area last spring. Plant has grown well. Alba is not tall but very spreading.
Live in Reno. Climate is classified as high desert. Weather highly variable. This winter not terribly cold. Few branches died back but plant is very healthy.
Major issue is size of blooms. 3/4 inch would be generous. Hope blooms do better this year.
