Okay, so last year I planted a bunch of jewel-blend nasturitums. At the end of the season, I plucked about 30 seeds and stored them away for the winter.
Spring arrived, and I was able to get one of them to sprout!
So, my nasturtiums are the first flower I have ever taken from flower, to seed, back to flower!
My photo album shows how I put them in the ground and supported them with a decorative plate holder that I bought for $8 from the local second-hand furniture store. I feel so smart!
