  <description>During the time my Osakas were flowering, I tried hard to not let other mustards flower, but I was not entirely successful.  Some komatsuna from a mix flowered, some tyfon-holland flowered, and some mizuna flowered.  Most of these I removed within a day of the flowers emerging, but the mizuna was sneaky.  A stalk of it got tangled inside the tomato cage I used to contain a cluster of flowering Osakas -- and I never noticed it until after I harvested all the Osaka seeds and removed the plants.  I may even have accidentally harvested some Mizuna seed, although the plant was pretty small and sickly looking, and didn't have many seed pods on it.

Obviously, any of these could have crossed with the Osakas, but the mizuna was extremely likely to given its close proximity and that it went unnoticed for so long.  I've been wondering if this would cause the Osakas to lose some of their purple coloring, or if I'd end up with awesome purple mizuna.  I suspected that greening would be more likely.

Most of my self-seeded Osaka purple mustards look just like their parents, with the same dark purple coloring, but there are a few that are nearly-solid green.  I'd say 10% of the plants or less are solid-green.  They otherwise look just like the Osakas, and they taste the same, but they don't have that coloring.  I suspect this is the work of the mizuna or other mustards.  Were I saving seed, I would rogue these out, but I suspect this will eventually be frost-killed or eaten before they can go to seed.

I've been swapping these seeds with several people lately.  In every swap packet, I have been sprinkling in a few commercial Osaka purple mustard seeds, partly for genetic variation, but also to further dilute the proportion of greens.</description>
