If anyone knows of a nursery that carries either of Gold Badge or Allgold please let me know. I’m after them for use as ‘calibration standards’ for my reflectance spectrometer more than for use as breeders. Hortico lists them but I don’t trust them, and the other sources listed at HMF either don’t actually have them or are not domestic (USA).
Heirloom carries Climbing Allgold but I’d prefer to have the real thing because a lot of data will rest on the measurements.
