I try not to go out into the garden without my pruners. My holster really should remain clipped to my front pocket from daybreak to sundown because, like most gardeners, I’m apt to bolt outside suddenly, mid-sentence and whenever they’re not on my hip I’ll want to remove a dead branch, give nepeta the Chelsea chop (it’s time), or pick a few tulips for the kitchen table. And even though every time I go outside I tell myself it’s “just for a look,” I wish I could also remember to grab an empty tubtrug in case I pull a giant pile of weeds. (Happens every time.) And right now I might never make it back inside to finish this sentence if only I pocketed a trowel too.

I never know how much honesty (a.k.a. money plant; Lunaria annua) I want in my back border until I see it blooming. This spring, like every spring, I have too much of a good thing. A flash mob of purple flowers held on spires above gray-green heart shaped leaves fill the bed, completely surrounded by silvery seedlings that will flower next year. Even though yanking a healthy and/or beautifully blooming plant out of the earth rubs every gardener’s moral fiber the wrong way, a little editing is essential, not only to keep the garden from feeling overwhelmed by certain plants but also to preserve our affection for them. As soon as any plant is allowed to “take over” we’ll diss it as a weed and some of us go so far as to tar benign old favorites with the “invasive” label. (Truly invasive plants warrant streams of invective and banishment by whatever means are necessary.) I never want to feel that way about honesty; some of it has to go.

It’s too late to transplant the blooming clumps—that would be psychically so much easier than composting them—but it’s not too late to move next year’s tiny seedlings. This week a few trowel scoops will make the move to my front garden, and I’ll look forward to editing out the blooming extras in those beds this time next year.

Honesty isn’t the only self-sower in my garden willing to fill the lot but most of the others aren’t blooming yet, which makes them much easier to transplant. Feverfew (Tanecetum parthenium) likes to put itself at the sunniest front edges of beds, which would be fine if its insect-repelling June clouds of white daisies didn’t obscure every shorter thing behind them. I tucked most back in mid-border and chucked a few to make way for plants the pollinators are willing to visit. Tall verbena (Verbena bonariensis) seedlings crowd the front row too but I’ll let some stay there because they’ll grow up to make a pretty see-through screen topped with butterfly landing pads.

Clumps of sherbet-orange Atlantic poppy (Papaver atlanticum) are budded all over my garden, front, back, and in between. I’m inclined to leave a few where they landed instead of moving them around because they’re tap-rooted and don’t love being transplanted. I also have more black and brown-eyed Susans (Rudbeckia hirta and R. triloba) in my garden than anyone without several acres should boast. If the memories of their black seedheads poking prettily out of snow banks weren’t still so fresh, I might be tempted to evict them all. Instead, I’ll keep a couple here and there to please me and the goldfinch next winter, pass a few along to friends who claim to not have any yet, and pitch the rest.

I can’t imagine resenting nature’s generosity though I know a lot of gardeners do. I say, “easy come, easy go.” Self-sown seedlings, along with divisions of any perennials that have overgrown their allotted spaces, give me the chance to hone my design skills and change things up—for the better—every year.
