Gardeners' Notes:


On Feb 12, 2012, RosemaryK from Lexington, MA (Zone 6a) wrote:

According to Mike Dirr's book , Carl Kern Cincinnati Ohio introduced it around 1953, though some sources say 1957. It is probably the same as 'Rosace' and 'Pink Sensation'. The pink shade is reportedly genetic and not influenced by environmental factors. Form is reasonably vigorous, maturing between 6-10 feet.

Also, I believe the correct species name is plicatum f. plicatum. The tomentosum category belongs to the doublefile group, and this is a snowball, and also sterile, therefore no fruit.

I grow 3 of these shrubs and the one that is pruned into a standard gets everyones attention every year. The blooms just seem to float in the air with the neat way this specimen was trained and pruned.....and I have had several offers from people to sell this plant. Of course the answer is always "No" and it still grows happily in my garden... :0) Lovely pink shades to the blooms, good Fall color to the foliage, and no disease problems whatsoever! We should see more of this shrub in gardens - Lovely!
