You might try Bill Maryott's website for what you want. He has developed a template for showing parents and offspring. One time I offered seeds to a HS Biology teacher, who said that they could get seed that grew in 6 weeks, so why wait for 1-2 years? Just yesterday, I thought about building an 8' X 16' seed bed at a local Christian Academy and covering it with a mini hoop house this winter to get surplus DL seeds to bloom maybe next late spring before they leave for summer. I may pursue interest this week.
