I have 6: 'Bartzella', 'Cora Louise', 'First Arrival', 'Julia Rose', 'Momo Taro' (Anderson/Seidl/Bremer), 'Morning Lilac', 'Unique'. Only 'Bartzella' bloomed so far and it is still a young plant. And potted 'Unique', planted last October.
Frank, could you post a picture of 'Unique' please? I am trying to compare it with 'Scarlet Heaven'. Picture of them in different catalogs and Carsten Burkhardt's database are different (even number of carperls differs from 3 to 7). I am a little surprised with the color of my 'Unique' but it could be just the first bloom and cold weather (it would bloom in July in the garden).
