Detailed Information

Flower: Flower shape: 5-petals Flower shape: tubular

[photo of flowers] Flowers are single in leaf axils along branching stems, trumpet-shaped, about 1 inch diameter with 5 spreading lobes, on a slender stalk that may be longer than the attending leaf. Flower color varies from blue to violet, sometimes white. The calyx cupping the flower has 5 narrow lobes shorter than the floral tube. Inside the tube are 5 stamens and a green style.

Leaves and stems: Leaf attachment: opposite Leaf type: simple

[photo of leaves] Leaves are opposite, evergreen, leathery, lance-elliptic to egg-shaped, ½ to 2 inches long, up to 1 inch wide, toothless, hairless, blunt to pointed at the tip, and on a short stalk. New leaves may initially be bright green, the upper surface becoming shiny dark green, the lower more silvery. Stems are woody near the base, may reach 6 feet long but creep along the ground, rooting at the nodes and forming dense mats; flowering branches more erect but rarely exceed 8 inches tall.

Fruit: Fruit type: capsule/pod

A flower may produce a pair of slender bean-like pods ¾ to 1 inch long, each containing a few seeds, but fruit is rarely produced.

Notes:

Periwinkle is a European introduction long touted in the nursery trade as a tough, fast-growing ground cover; there are a number of cultivars bred for flower color and/or variegated leaves. It can escape cultivation and is particularly problematic in woodlands, where it can form dense mats and crowd out native species; it is currently considered invasive in Wisconsin. One report from Indiana noted it covering acres of native forest forming a stand so dense it excluded nearly all other vegetation, including reproduction of the trees. It's only been recorded once in Minnesota, escaped from a cemetery planting in Rice County, but is likely under-reported here.

Periwinkle is recognized by its low-growing form with creeping stems; shiny, evergreen, opposite leaves; stalked flowers single in the leaf axils, typically blue to violet with 5 spreading lobes; fruit is a pair of bean-like pods but are rarely produced. The flowers resemble those of a Phlox, which have a terminal cluster of flowers; all of the native Phlox in Minnesota have erect stems, not creeping. The leathery, evergreen leaves vaguely resemble some low-growing members of the Ericaceae family, such as Wintergreen (Gaultheria procumbens) or Bearberry (Arctostaphylos uva-ursi), which have alternate leaves, clusters of small bell-shaped flowers, and typically abundant bright red, berry-like fruit.

I have a bunch of it. My Aunt planted it around '60. I did not know that it was invasive. I also have that bulb plant (Silla) I heard that is invasive too.

My property has a section of this that is slowly taking over. I want to remove this and put in a native ground cover that is low (less than 6-8") and can withstand shade and hot mid-day sun. 1) what is best way to get rid of a large amount? 2)what suggestions of native plants are recommended instead?

Julie, we aren't experts at controlling various weeds, so try asking Master Gardeners at UM Extension. We have learned that if you dig, any root fragments left in the soil can resprout, so you'll need to be tenacious about pulling new growth. For other info on gardening with native plants, check out Wild Ones, whose mission is to promote gardening with natives; there are several chapters in the Metro area.
