Hybrid glauca. Ruglauca was one of 8 seedlings that Rob Byrnes received from Joan Monteith during the summer of 2007. This seedlings bloomed in its first season while only 8" tall. Petioles are red and new stems are pink colored with a downy look/texture to them. In the fall the leaves turn a nice golden color. Sparse thorns.
This is an openly pollinated seedling that may be self-pollinated. Will set some OP hips and will occasionally take pollen from other roses. Rugosa #3 is reported to be a plant converted to a tetraploid which might make Ruglauca a tetraploid as well.
Rooted plant sent to Joe Bergeson spring of 2012.
