It is time to cut the milkweed out of my garden.
I planted it many years ago. It never sprouted. Four years later, there was a tiny plant that looked suspiciously like a milkweed growing next to some peonies. I clipped a leaf off to see if it would ooze the sticky white sap that gives milkweed its name: it oozed. Excited, I let it grow. The milkweed plants are limited to a “triangle” between the garage and two sidewalks. I cut them down when the seed pods appear: I don’t need more plants. Also, I don’t want to wait another four years for the seeds to sprout when the plant does just fine by sending out runners from those very sturdy rhizomes.
I was afraid the milkweed would crowd out the peonies and the asters. It doesn’t. The three plants grow together happily. What the milkweed did affect was my arum, dracunculus vulgaris, or “Dragon Lily”. The milkweed runners take up the space the lily’s bulbs are in and I’ve slowly lost many plants in that tiny garden space. There are a few left and this fall I will dig them up and move them to a better location, free of water- and space- hogging competition.
Unfortunately, milkweed does nothing to impede the growth of grape hyacinth, I don’t think anything short of a heavy-duty herbicide affects grape hyacinth (and I refuse to go that route). Every year I pull several hundred bulbs out of the ground and compost them. (Sometimes, I will give them away to a desperate gardener who doesn’t know better than to start them in their yard. I’m pretty sure I’m digging up bulbs to send to my brother in Reno this fall. “Hey, Bro, your yard needs some early spring color. I promise you won’t hate me in ten years…”)
Now, when the first purple grape flowers begin to bloom, I do my first – and only – weeding of the space. I cut hyacinths for a bud vase. I toss the ones that pull up with the ever-present grass. I do my best to rid the space of grape hyacinth bulbs while enjoying the aroma and color. Of course, I fail and the hyacinth prevails.
In the Spring, I cut back the old stalks of peony and aster just as the first new stems begin to push their way skyward around the fading hyacinth. Purple stems of peonies, green stems of aster, the spotted stems of Dragon Lily rise above the fading green and brown stems of faded hyacinth. Buds form on the peonies and soon the area bursts with pink and red peonies so thick I have to tie them to stakes to keep them upright.
The peonies fade and drop their petals just as the aster and the milkweed stalks begin to mature. The green of the aster is first to top out at 2-3’ tall. Milkweed will soon tower over the asters and all one will see will be the green stalks of milkweed.
But before it does, at the end of May and always on our anniversary on the 7th of June, the aroma of rotten hamburger wafts in the air: the Dragon Lilies have opened. Flies and beetles rush in to await their demise in bowl of this carnivorous beauty. The smell lasts a couple days. The flowers wilt and the entire plant begins to wilt and turn yellow.
Now it is the milkweed’s turn.
I have two varieties: Showy milkweed (Asclepias speciosa – native to Oregon) with pink florets and California milkweed (A. Californica) with white florets. The latter isn’t a native to Oregon, and it doesn’t grow as prolifically as the Showy milkweed does, but the blooms are pretty and the aroma is the same: sweet and enticing, the polar opposite of the faded Dragon lily.
I planted milkweed thinking I could attract migrating Monarch butterflies. I didn’t know then that this part of the lower end of the Willamette Valley is not on the migratory path for these beautiful and endangered butterflies. No worries: the value blooming milkweed has for other pollinators outweigh my misplaced intentions. Every early bee, butterfly, and tiny wasp brave the sticky edges of the flowers to get at the pollen inside. Occasionally, a honeybee will get stuck and will have to struggle free. A few plants wilt and die, host to the milkweed beetle which does exist in this half of the valley.
Below the tall stems that now tower between four and six feet, a junco might build a ground nest. The nests are soft grass circles, now much larger than the palm of my hand. We won’t know there’s a nest there until a fledgling bird hops out of the cover while the parent birds hover nearby.
The bloom of milkweed lasts a couple weeks giving us quite a show of pink and white, and busy pollinator insects. But then the flowers fade and the few that were pollinated will start developing seed pods. These are green and soft, and quite edible if you are not allergic (I am). When the pods ripen, they turn brown and hard then pop open to release thousands of sees hanging from wispy “umbrellas”. The wind catches the seeds and like the dandelion – well, you know the rest of the story! The ground is soon covered in tiny, milkweed parachutes looking for a home.
But I mow down the milkweed, not simply to avoid the parachutes, but because the milkweed towers above the asters. And the asters put on a late show of color lasting through August and into September. The tall asters are a riot of magenta pink. The aster that grows in the crack in the sidewalk puts out lilac-colored flowers. The tiny bees – those mining bees and other ground dwellers – love the asters.
The milkweed is gone now, and I wait for that last eruption of color. Too soon, the rain will come and everything will turn brown. (Photo is of a year I did not cut down the milkweed stalks and the seeds flew everywhere.)
