One of the most difficult roses to grow in a cold climate is a yellow rose. I don’t know the genetics about it, but do know I’ve never seen a wild yellow rose up here. The hardiest roses tend to be pink with a few white ones showing off occasionally. True red roses are also difficult. I’ve tried growing Harison’s Yellow Rose and, although it has lived and returned for three years, it has never thrived and only allowed me a couple of spindly token blooms. Ralph Moore’s TOPAZ JEWEL, above, keeps returning. It’s never attained a respectable height, but it isn’t stingy with the flowers. The blossoms only last a few days at most, and occasionally set hips, but the repeat bloom cycle makes this a treat either in a pot on the deck or in the garden with purple Lobelia planted at its feet.
