Under street trees, replace resource-hogging plants with low-care groundcover plants, such as Geranium Macrorrhizum, or bigroot geranium, suggests Evelyn J. Hadden, author of "Hellstrip Gardening" (April 2014, Timber Press).
Even a tiny strip can be filled with plants, a more nature-friendly choice than gravel or wood chips, says Evelyn J. Hadden, author of "Hellstrip Gardening" (April 2014, Timber Press). A no-mow variegated sedge (Carex morrowii ‘Silver Sceptre’), in Newton Lower Falls, Mass., shows an great alternative to needy lawn.
A short-lived perennial herb, 'Creeping' thyme, is relatively easy to overwinter indoors. Grow it as a houseplant in a sunny window. Outdoors in hardiness zones 5 to 9, it fills in between stepping stones and makes an aromatic groundcover.
