Louis Pasteur once said: “Chance favors only the prepared mind.”
This is as true for gardeners as it is for scientists. I’m constantly finding wonderful gifts from Mother Nature, volunteer plants like Japanese Maples, Weigelas, Hydrangeas and Magnolias, and I try to be “prepared” in order to avoid yanking out the good guys along with undesirable weeds.
Recently, though, I was stumped by an interesting grass-like volunteer growing in a large container of clematis. It had multiple stems ending in a starburst of foliage centered with a cluster of spikelets. I liked it a lot and transferred it to a pot of its own. Photo below.
Then I sent off a photo to The Cornell Cooperative Extension requesting an identification. The plant’s ID, Yellow Nutsedge, arrived with a warning: “Yellow Nutsedge will spread readily by seed . . . you might want to cull this plant!” And my go-to reference book on grasses and sedges agreed, calling Yellow Nutsedge (Cyperus esculentus) an “infamous” and “pernicious weed.” So much for a pretty face!
I do grow two showy, variegated grasses with stellar reputations and I’m happy to recommend them:
Arundo donax ‘Variegata’ (Zones 6-10) is a hardy, compact, deer-resistant, green and white boldly striped form of Giant Reed Grass. Photos below.
In my garden, Zone 7, it dies back in winter and returns in the Spring. It has never flowered for me and since it doesn’t set seed it is not invasive like the standard form of Giant Reed Grass. While it has been said that Variegata requires sun, my plant flourishes in shade. This Autumn it’s been embraced by a volunteer pink-eyed aster, enhancing the garden presence of both. Photo below.
Miscanthus sinensis ‘Morning Light’ (Japanese Silver Grass. Zones 5-9) is a hardy, deer-resistant, silvery, shimmering, award-winning fountain of elegance. In the Fall, Morning Light produces abundant, pink, tassel-like flowers and thereafter plumes of white seed heads that last well into winter. In the Spring, my plant has to be cut back close to the ground to make way for the new growth. Photos below.
I have been delighted to find a number of Morning Light’s progeny popping up in the garden.
