Talking about Hen and Chicks (Sempervivum 'Greenwich Time'), valleylynn wrote:

A quote from Kevin Vaughn:
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.

A comment from the breeder of 'Holly Jolly'.

JungleShadows said:Holly Jolly is one of the more unusually patterned Killer seedlings and it did SCREAM XMAS because of the red and green coloration. It's not as big as some of the others from those groups.

Oddly enough I haven't used it much in crosses. I was concentrating on the bigger siblings. (much to Bev's chagrin!)

A quote from Kevin Vaughn:
JungleShadows said:Weirdo isn't quilled but it is ODD. Splits and produces rosettes at strange places and never has a proper center. Very unkempt!

Talking about Hen and Chicks (Sempervivum 'Belladonna'), valleylynn wrote:

A quote from Kevin Vaughn:
JungleShadows said:Aymon Correvon and Belladonna are nearly sterile. Aymon Correvon is a montanum X wulfenii cross so two diploids with different chromosome counts. It is the plant equivalent of a mule. Belladonna is montanum X somebody but i'm not sure who. I still try each year to cross on to Aymon but so far not seedling one. Greenwich Time is montanum X calcareum and i have exactly ONE seedling. It is a nice one though!
