Oddly, I got a 12pk with 3 nasturtiums in each cell at the farmers’ market two weeks ago which were intended to sell as microgreens you clip and sprinkle your salad with. I chose to plant them at 1/10th the cost of nursery Nasturtiums. I’ve had horrible luck germinating them over the years, and had given up.
The variegated Alaska variety hates me; I bought an Empress of India (blood red blooms) that’s doing great.
My neighbor threw the remains of a salad over her deck that had Nasturtium blooms in it. They germinated and covered the rocky hill slope garden, she asked me what are those plants? Talk about grrrrrrrr. I can’t get one from seed but she did, unknowingly.
