JungleShadows said:'Greenwich Time' is from 'Cleveland Morgan' X calcareum. It goes through a couple phases, sometimes looking like a more purple larger version of 'Cleveland Morgan' and sometimes looking like a velvety calcareum. Helen didn't believe me when I told her the pedigree as she had never had calcareum bloom. Several years later a box arrived from Helen with a blooming calcareum and a note attached saying "I believe you now".
It was from my very first year of crossing, If you cover the calcareum stalk you will see that it makes TONS (well maybe not tons, but lots) of pollen. I dud use 'Extra' and 'Guillaume' in crosses last year and rediscovered what I had known in '64: calcareums make lots of pollen!
The only bad thing about 'Greenwich Time' is that it's a cross of two diploids and nearly sterile. I had one seedling last year and about 6 this year from open pollinations. I do save those as they are likely to be odd combinations of things genetically.
