I planted this rose as a small band in my Zone 6b CT garden last year. This spring it has produced a few buds (which have unfortunately been nibbled by caterpillars). I had heard that this rose could take several years to produce a bloom, but I've found that it isn't different from any other Gallica that needs a winter chill to perform. So please take the low ARS rating with a grain of salt. Duc de Guiche was actually a much stingier plant!
