Carol, I maintain a daylily database that I have used for years. It's just an annual record keeping document with the following headings:
Name
Appearance
Date Added
Height
Bloom size
Bud/scapes (this is from the hybridizer)
Bloom time
Hybridizer
Year
Source
Price
Foliage (EV, SEV, DOR)
Price
Ploid (TET, DIP)
I also keep an annual alphabetical bound notebook with a label on each page with a plant's name and a summary of info--hybridizer, year, bloom time, etc. This is where I keep notes detailing plant performance.
This notebook goes into the garden with me. The database doesn't.
Hope this helps!
