One of the largest plants for a Hybrid Tea in our Maine garden. Nicely formed dark red buds open to a high-centered flower of about 25 petals. Some fragrance, the blooms come in singles and large clusters. Although we must protect it for the winter, we haven't lost it in the 14 or so years we've grown it.

I was impressed with the size and quality of the blossoms; however, I lost the plant over the winter. I would definitely grow it again, but in a more protected location.

This is a very nice hybrid tea. It blooms prolificly after getting established. The blooms are big and well formed. Very double. A very faint fragrance. Cold hardy and vigorous. Excellent.
