Peach-Leaf Bellflower: Garden Enemy #2

I was out in the garden on the afternoon of New Year’s Eve, doing what I expected to be routine cleanup — cutting down old perennial stalks, removing the odd overgrown specimen, etc. But I realized I had a bigger problem on my hands — peach-leaf bellflower (Campanula persicifolia), entrenched and spreading all over one of my sunnier and tree-root-free perennial beds. A planting of variegated irises and a specimen of Eryngium yuccifolium were threatened with oblivion as the peach-leaf pest sent out new offsets and and an ever-thickening mat of roots.

I happily included this plant in my post called Tough Plants for Dry Shade, and I still think it belongs there, but now I issue a warning:  do not plant Campanula persicifolia in places other than dry shade, especially if you garden on light, sandy soil. In hospitable, sunny spots, it becomes a rampant thug. Plant delphiniums there instead.

In a hasty attempt to get rid of the unwanted bellflowers, I went from hand-pulling (useless except for seedlings or brand-new offsets), to stabbing with a trowel, to deploying the gardener’s big gun — a digging fork. That did the trick, except that I dug up a bunch of tulip and crocus bulbs along with the bellflower mats, and, worst of all, sliced off a nice hyacinth bud that was awaiting spring under the soil surface.

That’s the really awful thing about spreading plants — they cover up other plants and, unless the gardener has a really good memory and/or really meticulous records, render them invisible. The busy gardener glances over a bed and sees nice, healthy plants of peach-leaf bellflower, totally forgetting about the irises, eryngiums and bulbs that were planted there in the first place. When the truth finally dawns and Something Must Be Done Right Now, havoc and destruction ensue.

Some may say I’m being unfair to Campanula persicifolia. Just because I was too lazy to keep an eye on things, I need not vilify the bellflower, which is an attractive and reliable plant. Maybe so, but gardeners should know about a plant’s bad habits before they introduce it into their premises, so I think this screed is justified. (And of course I’m still upset about that hyacinth).

On a related topic, following my post on Plant ID, in which I made observations about different kinds of plant labels, I actually received as a Christmas gift a couple of dozen rather nice permanent metal labels with solid plastic stakes to hold and display them. I’ve decided to use them to mark valued plants that are at risk of being overwhelmed by the rambunctious “tough plants” that I have allowed to proliferate here. The idea is that the labels will remind me to check on the well-being of the plants they represent, thus ensuring that the markers will not be of the RIP sort.

Oh yes — and what is Garden Enemy #1? In my garden, it’s those maple trees, of course. I’ve ranted about them before, and will likely do so again.
