On Dec 5, 2004, lmelling from Ithaca, NY (Zone 5b) wrote:

Information from both "Hydrangeas for American Gardens," by Michael A. Dirr (2004) and "Encyclopedia of Hydrangeas" C.J. and D.M. Van Gelderen (2004 - Timber Press).

'Alison' grows 8'- 10' high and is a clone discovered and named about the same time as 'Alice'. It is also broader spreading than 'Alice'. Found by Michael A. Dirr, on the Geogia campus and named after Alison Arnold, one of his master of science students.

Flowers late in May to early June (Athens, GA), and easy to root from cuttings. Flowers are 10 inches long (with some up to 12"), equal distribution of fertile flowers and showy sepals. The inflorescences are pyramidal and held more upright than 'Alice'. Foliage is lustrous dark green with stunning almost fluorescent red-burgundy fall color.
