What grows one to three feet high, has small blue-green leaves, clusters of pretty yellow flowers, and is a stubborn, nasty, and aggressive noxious weed that is supported by an extensive system of underground stems? Probably the only good news is that it isn’t typically a weed in most landscapes, but if you’ve been out hiking much lately, you’ve likely encountered Leafy Spurge.

A weed is…
I subscribe to a variety of online gardening groups, mostly on Facebook. Lately there has been a lot of ranting discussion about whether or not dandelions are weeds. On the one hand, various gardeners are asking for help controlling dandelions in their lawns and gardens, often to please a landlord. On the other hand, various opinionated persons climb onto their soapboxes and extol the virtues of dandelion leaves, wine, and bee-friendly flowers, chastising anyone who would dare to disagree.

After the storm earlier this week, snow blankets the fields, hiding most signs that anything ever grew there. But interspersed with the even white blanket and occasional dried grass leaves are spikes, sticking up like posts in the empty landscape. We’re finally noticing the dead and dried flower/seed stalks of Common Mullein (Verbascum thapsus).

You’re growing morning glories? On purpose? Are you crazy? Those things will take over your garden! Our friends, who live in wet western Washington, were appalled. They couldn’t understand why I’d plant something so invasive.
Yet, I’ve grown morning glories for years, first in California’s benign climate, then here in Colorado. I’ve never found them to be at all invasive. True blue flowers are hard to find. I couldn’t understand why our friends, avid gardeners, wouldn’t want to grow something so lovely.

The flowers could be considered somewhat pretty—a white or lavender tuft reminding me of cornflowers (aka bachelor’s buttons). The somewhat pretty flowers are probably the only positive aspect of these plants. A common noxious weed, knapweed is the bane of my garden.
The problem is that we live immediately adjacent to an open space, a few supposedly wild acres left by the developer (probably because it’s too steep to build on). There’s Gambel’s oak, six Ponderosa pines, a smattering of yucca, assorted wildflowers, and some rather nasty weeds.

They sound pretty good— perennial plants that:
- Are hardy in Colorado, even in the mountains
- Grow a compact one to two feet tall
- Are covered with eye-catching white daisies in mid-summer
- Grow in almost any soil
- Bloom in full sun or partial shade

Worth growing for its delicious fragrance alone, dame’s rocket also offers showy, long-lasting flowers and is as trouble-free an herb as you could ask for. Its multitude of common names attests to centuries of cultivation in gardens and to the high regard in which it has been held. (Mother Earth Living)
How can you resist such a glowing recommendation? It’s true that dame’s rocket is all these things, but it is also an invasive outlaw, wanted dead, not alive. Like any most-wanted suspect, Hesperis matronalis hides under a plethora of aliases: damask violet, dame’s-violet, dames-wort, dame’s gilliflower, night-scented gilliflower, queen’s gilliflower, rogue’s gilliflower, summer lilac, sweet rocket, mother-of-the-evening, vesper flower and winter gilliflower, to name a few. But not matter what you call it, it’s against the law to grow this plant in Colorado.*
