A page for wildflower and hiking enthusiast. A lot of my pictures, both wildflowers and scenery, come from the beautiful Tennessee State Parks. I use the Lady Bird Johnson Wildflower Center for my description of native plants. All non-native plants will use someone else for the description. The best way to follow this blog is to enter your e-mail address below. You will receive an e-mail that looks just like the post with all the pictures.

Comments are encouraged and appreciated. We are amateur botanist, and we do make mistakes sometimes with our identifications. We strive to make this a good identifying resource. All comments are moderated by me and may take several days to appear. This is due to the high number of inappropriate comments that have nothing to do with this subject.

Common Periwinkle (Vinca minor L.)
Family: Dogbane
Common periwinkle, is a native of Europe often escaped from cultivation. It is a perennial evergreen ground cover that is winter hardy. It is closely related to the big leaf periwinkle (V. major L.), except in size and hardiness. Common periwinkle seldom exceeds a height of 6 inches although runners may trail long distances on the ground. The runners root at the node under moist conditions. The thick glossy leaves form a good ground cover. Small blue flowers occur indeterminately from April to September.
Common periwinkle is adapted to mild climates. It usually requires part shade and ample moisture, but will tolerate full sun if it is adequately watered. It is more hardy than big leaf periwinkle. Moisture and exposure are often more restrictive than soil type on determining adaptation. Common periwinkle is adapted to a wide range of soils. It is found on well drained to poorly drained soils that can be calcareous, alkaline to slightly acidic, and medium textured to fine textured. The plant should be used where there is adequate moisture.
Common periwinkle is distributed throughout the East. It is found through out TN especially on old home sites and cemeteries. Sometimes it is the only indication that a cemetery is close at hand.
Photographic Location: Volunteer Trail at Longhunter State Park in Middle Tennessee.
Plants may be established from rooted cuttings produced in flats or from plant division. Plant on a spacing of 18 inches x 18 inches. Fertilizer should be applied for vigorous establishment. Mulch critical areas immediately after planting. Planting can be done any time of the year when moisture is adequate for establishment. This should ordinarily be planted on areas that can be sprinkled or otherwise irrigated or on sites where average annual precipitation is over 20 inches.
