Instead of the blooms described on the identification placard, there were only a few, very dull, pink, non-fragrant blossoms in early spring and no more since then, not even any buds. As you can see from the photo, it has produced much luxuriant growth, without any sign of disease (except for few yellowing leaves in lower part of plant on one cane). Can you please help me understand why and what I need to do to get more and better blossoms next season? – Multnomah County
