I have been thinking a lot about growing species of "rare" bulbs from seed saved from our own plants. In nature, when the population of a given species is very small, they can succumb to inbreeding depression. I wonder if this happens in our own gardens with, say, species of Crocus that are rare in cultivation. By saving our own seed, are we in effect creating non-resistant forms of otherwise hardy and fit species? Could this explain the phenomenon of "hybrid vigor", by expanding the gene pool? This is of course a rhetorical question, it was inspired by Ian Young's Bulb Log -Travis Owen Rogue River, OR http://amateuranthecologist.blogspot.com/
