It’s that time of year when I have to tackle the problem of the invasives. Perhaps a wall would work. No, that’s just ridiculous. Last year’s attempt to eradicate bishops weed by meticulously digging it up and removing the stringy roots, only resulted in it multiplying tenfold. It’s now growing among a planting of Carex ‘Ice Dance’, dwarf hosta, and autumn blooming heuchera, which

Campanula come in all shapes and sizes. Some can be pretty invasive!
was exactly what I was hoping to avoid. Cutting it back and then spraying the new growth with and herbicide seems the best way to go. I’ll cover all the desirable plants with nursery pots so they don’t get sprayed.
It’s easy to forget how invasive Campanula ‘Elizabeth’ is when it blooms with its large upside-down mauve speckled bells, but I’ve been aggressively weeding it out of one of my beds for several years, and have been able to successively knock it back to just a couple of stems by this method.
The tiny sedum murale can’t really be described as invasive, but it has propagated itself so well in my gravel pathways, that I no longer have gravel pathways. It pulls up fairly easily, but I’ll see if it pops right back up again from its tiny hair-like roots.
Corydalis lutea i
s the number one requested plant that customers see in the garden center. It’s one of the longest blooming plants, and so is one of the most prolific. Lacy little seedlings will sprout up every where if I allow it and big billowy mounds of it spring from underneath stone edging. Its gotten to the point where its filling in my paths. The succulent stems are easy to pull out and I know new seedlings are days away from reappearing.
Daylily season will soon be starting!
I had to tackle a hellebore bed off my back porch. They had reseeded and were getting too congested. Some hellebore become rather tall, and at eighteen inches, was rapidly smothering an english boxwood and nearby lungworts. If you’ve ever dug up a patch of hellebores, you can see why they’re drought tolerant. The roots are very fibrous and deep. Underneath was hundreds of 3″ seedlings. I’ve transplanted the whole lot to one of the woodland gardens, where it will form a dense evergreen cover. I don’t want or need anymore new plants, so I cut all the stems off before they go to seed.
Now is a good time to pinch back any perennials that flop over. In my garden, I’m pinching back sedum ‘Autumn Joy’, phlox ‘David’, the towering rudbeckia ‘Henry Eilers’ and helianthuis. They will be much fuller at the base and may bloom later than usual, but I’m okay with that. The variegated Japanese grass always collapses mid-summer, so I’m going to cut it back to the ground in a few weeks. It will shoot up shorter and fuller.
Red Charm Peony.. best red?
June is the time for big flowers. Peonies, roses, clematis, wisteria. There’s nothing shy about these bloomers. The ‘Queen Alexandra’ poppies are blooming out of sync with a’Diabolo’ physocarpus. Its a beautiful combination but just once have they bloomed together. So much for careful planning.
One combination that is going as planned are the rugosa roses planted with ‘Rose Sensation’ salvia and a dark-leaved heuchera is in the front. Echinops silvery grey leaves make a beautiful contrast for the fuschia-purple roses and will begin later. Pairing plants in successful combinations can be difficult, but I think its one of the creative parts of gardening.
Just when I was feeling smug about having a weedless garden, the rains came and suddenly weeds are up to my knees. Jewel weed with its brittle stems is easy to pull up, but when will they stop returning? Clover is the worst since its low to the ground and its sometimes bronzy leaves are difficult to see. Ash tree seedlings are coming up but are easy to pull out when they’re small. A very pretty silvery ferny weed that comes up in my gravel is pretty enough to use as a groundcover and is commonly known as cudweed, catfoot, or rabbit tobacco. Catchweed or bedstraw has tiny sticky seeds that get tangled in my dogs fur and has to be eradicated as soon as I spot it in my woodland garden.
Peonies are in full flower
There isn’t a weigela I don’t like, and my gardens are full of them. They’re easy to grow, will take a little shade and come in a range of sizes and leaf colors. An unusual lime green variety bloomed in my woodland garden about a month ago, and now the low-growing variegated ‘My Monet’ has begun along with a very large reddish-pink old variety that an aunt gave me when we first moved into our home. She rooted several up just by taking cuttings and pushing them into pots of soil. The flowers are the perfect shape for early arriving hummingbirds and bees. I planted one of the re-blooming Sonic Bloom varieties last summer, and I’m curious to see how its going to perform this year. The larger variegated forms are placed more for their foliage rather than their flowers. They brighten up any mixed planting and look fantastic with darker shrubs like smokebush and physocarpus.
Pulmonaria is getting a little leggy and I’ll cut these back as soon as they finish blooming. This will create a nice compact shape. Candytuft is finished blooming as well and I cut it back hard or it will take over my rock garden.
My rock gardens needed attention as well. I remove any leaves that have gotten stuck under plants and lift up any stones that have sunk too much. If the hen and chicks look too spacey, just slip a trowel underneath, loosening the soil, and lift the up. Replant them closer together. A new top dressing of fresh gravel makes everything look neater.
