Slightly hairy rosettes, shades of pink, grey and red.
A cultivar that takes us back to the earliest days of hybridising Semps. Georg Arends (a famous Germany grower who bred and raised many garden plants) made the first recorded cross of two species to create the most appropriately named 'Alpha' (the first). That was in 1927, so getting on for 100 years ago.
We have come a long way since those early days, each generation of breeders building on the work of the previous generation, trying new combinations, adding different genetics.
Anyway, that 'Alpha' is still being growing today says much about it's general garden worthiness.
