I found this on amazon, as a used book around $10.,
It is basically about Sempervivum and sedum.
I usually mostly buy ebooks as I can increase the text size which helps my old eyes.
But in reading the book I realized how much research the writer had to preform or knowledge she possessed to write this in 1972. Now I just do a web search to find information.

Great find Ed. I have that book. I lived about 2 minutes from Helen's nursery in Dallas, OR. A young couple now owns it.
Many bits of treasure found in her writing that book.

Is that place belonging and DBA "Seedables"?

What is DBA?

DBA (doing business as) is a fancy way for companies to call themselves another name for legal reasons (kind of how Fanta soda is actually a sub business of Coca cola...)

After some googling, it seems as though Helen's nursery is called Hamblin's now? If so, the company Seedable Plants LLC has completely different owners listed for their company, and there is nothing relating the two companies together. There isn't much information about what Seedable Plants LLC actually is. Is it a Nursery?

I would love to get my hands on a book like that.

Seedable Plants is a small/young company. I'm not sure if it is listed. Right now they are doing truck gardening of vegetables.

@webesemps No, they did not buy Helen's place. Helen's place sold to a young couple back around 2000. You passed it every time you came to my Dallas house.

Thanks for the info, Lynn.
