I discovered that Harry Wheatcroft made an appearance on the US game show “What’s My Line” on Mar. 12, 1961. Easily found on YouTube.

There should be a new entry for rose, which should be called R. Banksiae “Fragrant Snowflake,” that Dr Basye created but wasn’t put here on helpmefind. In “Rose Rustlers,” by Greg Grant and William C. Welch, they quote from Dr. Basye saying:

‘This kindly old gentleman [Domenico Aicardi], then in his upper seventies, responded by sending me a generous handful of banksiae seeds, which must have taken him several hours to extract from the very small hips of banksiae. I have never forgotten his generosity.’

Then Grant and Welch wrote:

“Starting in 1969 […] Dr. Basye went on to use one of these new single thornless white banksias to produce his 85-04 ‘‘Thornless Fortuniana' rootstock, which he bred in 1984.

“I took cuttings of Dr. Basye's single white banksia with me as a historical curiosity and later planted it in my garden in Arcadia. Though not as showy as the double white Lady Banks, it is the most fragrant rose I've ever grown. [[…] I later named Dr. Basye's seedling 'Fragrant Snowflake and also sold it at our SFA Gardens plant sales.”

The single banks rose in commerce could be from Dr. Basye I think.
