One of my gardening triumphs this year was overwintering dahlias for the first time. One dahlia, to be precise -- the only one I have. I didn't really think that digging it up, keeping it in my basement for months on end, and then planting it again was likely to result in anything productive. And yet, here it is, blooming gorgeously again. I am resisting the urge to run out and buy a dozen more dahlias (because a) I don't have room for them, and b) my garden budget is thoroughly spent for the year), just because I'm so excited that this actually worked. I will definitely add a few more, at least, in the years to come. It's a bit of effort, digging it up and replanting it, but oh, so worth it.
Now, if I can just figure out how to grow some outhouse hollyhocks from seed. That's my next gardening hurdle. And if I can keep the kids from eating the neighboring foxgloves, I'll have two nurturing triumphs in one. :-)
