Ken emigrated to Australia in 1960. He and his wife Ruth established a nursery named Charmay, being a derivation of Ken's second name and his wife's first name. This was to be used as the prefix for all of the plants that Ken hybridised, of which there are many. Omega is the 24th and last letter of the Greek alphabet.
The second greenhouse was watered today. I had spotted a few whitefly on the angels and scented plants in there, so they were watered with a solution of Provado. I also washed more pots - where do they all come from?
