I've never been that big a fan of radishes but always planted some because the woman here likes them. Few years ago I learned that they can be fall planted to hep till and improve the soil when they freeze and rot. I got tired of buying seeds for that so started letting some early spring planted ones go to seed. Then I discovered that although I don't like them all that much that I do really like the seed pods. I don't have an idea now how many different kinds I threw in nor how much crossing and genetic mixing goes on.
I save a lot of seeds to plant in spring so the woman has hers and I have my tasty pods and more seeds to plant in the fall and then again the next spring. Lots of seeds end up lost and here and there in the process and one thing
led to another. Now radishes grow pretty much wild in my garden. They don't seem overly concerned with what time of year it is, they just come up here and there when ever they feel like it.
Some times the ones that volunteered later in the summer end up growing to what I guess could be called full maturity. As in really big, just as freezing temps threaten to kill them down. When I first found some like that I figured they would be fibrous or otherwise nasty but they aren't. They are really good, crisp and kind of sweet and not very radish-ish at all.
They aren't all like that, some are more like chewing on a stick. It's a little disappointing that I can't select for that sweet crisp trait cause at that point they are not ready to bloom and won't be before they freeze. O' well I guess I'll just enjoy them as I can, never knowing when for sure they will show up.
