I normally use Real Seeds but they had no salsify or Capsicum chinense, so tried seedaholic.com. I was astonished to receive the seeds, very well packed, with a colour instruction sheet with each packet, giving information on the species, planting, growing, harvestig and eating, very impressive. As to the seed quality, I can’t say. They look to be a reseller as per most of the big companies which means they buy in bulk, and distribute. Real Seeds grow the seed themselves, and also use some small growers they know and trust, which means you get better germination and consistency. Fingers crossed …
I’m not sure why salsify is not more popular, perhaps because cleaning is fiddly.
