This is about all I coudl find

Periwinkle
Periwinkle is also called vinca or myrtle. Of the 12 species of periwinkle, two are popular ground- covers. All species have opposite leaves and single flowers. The perennial periwinkle should not be confused with the bedding plant, Madagascar periwinkle (Catharanthus roseus).

DESCRIPTION
Periwinkle (Vinca minor) is an excellent evergreen groundcover with dark green foliage. Oblong to ovate leaves are opposite, simple, ½ to 2 inches long, glossy, with a short petiole. They exude a milky juice when broken. Flowers are purple, blue or white depending on the cultivar. Plants bloom in April and sometimes again in the fall. Vinca minor grows about 6 inches tall, spreading in all directions by sending out long trailing and rooting shoots, which make new plants.

Vinca major or large periwinkle is a larger, more aggressive species than V. minor. Leaves are up to 3 inches long. The blue, funnel-shaped flowers are 1 to 2 inches in diameter. They are borne in abundance in early spring and sporadically throughout the summer. Large periwinkle spreads rapidly and will mound up to 2 feet. Non-flowering stems root at the tips where they touch the ground.

LANDSCAPE USE
The trailing, arching stems that root where they touch the soil make these evergreen plants useful as groundcovers, for erosion control on banks, or for cascading from window boxes or planters. Periwinkle grows well under trees and shrubs, on shaded slopes or on the north side of buildings. Spring-flowering bulbs interplanted with periwinkle will lend color and interest to the groundcover planting. Daffodils are particularly well-suited since they bloom with periwinkle and do not require frequent division.

CULTIVATION
Periwinkle prefers shade but will grow well in full sun. The foliage color is richer green in partial shade, but more flowers are produced in the sun. Rooted cuttings or established plants are normally spaced from 12 to 18 inches apart. At a 6-inch spacing periwinkle will completely cover an area in one year. Plant whenever the soil is workable and provide sufficient water, especially when planting in summer. Weeding and mulching are required on a regular basis until the groundcover fills in the planted area. Periwinkle prefers moist, well-drained soil, abundantly supplied with organic matter, but it is tolerant of a wide variety of soil conditions. Fertilize only when necessary, preferably in the spring with a complete fertilizer such as 10-10-10 at a rate of 6 to 8 pounds per 1,000 square feet. Occasionally shear plants close to the ground to encourage new growth. Propagate by taking tip cuttings of non-flowering stems in late spring or divide throughout the season.

CULTIVARS OF PERIWINKLE
‘Alba’ has white flowers.
‘Atropurpurea’ has purple flowers.
‘Bowles Variety’ has blue flowers and grows vigorously in clumps.
‘Variegata’ has blue flowers and leaves variegated with rich yellow.
‘Flore Pleno’ has double, purple flowers.
‘Alboplena’ bears white, double flowers.
‘Jekyll’s White’ has single, pure white flowers and is more floriferous than ‘Alba.’
‘Sterling Silver’ bears dark blue flowers and foliage with white margins.
CULTIVARS OF LARGE PERIWINKLE
‘Alba’ has white flowers
‘Pubescens’ bears more pubescent leaves than the species and red-purple flowers with narrow petals.
‘Reticulata’ has foliage netted with yellow lines.
‘Variegata’ has creamy white blotches on the leaves. Flowers are blue and plants are sometimes known as ‘Elegantissima.’
PROBLEMS
Periwinkle is susceptible to dieback (plants wilt and "die back" to the ground), caused by fungal diseases. Cankers, which are sunken, woundlike lesions, may be visible on the stem near the groundline. Fungal leaf spots occasionally occur and look like brown circular-to-oval spots on the leaves. Infected leaves should be sheared off and discarded. To reduce fungal infection, avoid overhead irrigation. Chemical control is seldom necessary.

Vinca-V.major variegata is a varigated periwinkle-native to Europe is a tender perennial evergreen that is treated as an annual except in zones 9-10. Plant has trailing stems that root as they spread and carry dark green 1-3" leaves that are marked with white. The plants put forth 1-2"lavender-blue flowers with five flat, round edged petals. The varigated periwinkle must be started from cuttings rather than seeds. They will root in any season, but usuallythey are taken during the winter months so that good-sized plants will be available to set out when night temperatures remain above 50 degrees. I gave you info on the varigated periwinkle, figured you could benifit from this variety too! Hope it helps!!

"if i supply a guy a hundred funds i might desire to have HAD a minimum of a hundred funds" - it is not real. you will have a financial business enterprise account with not something in it. in case then you definately purchase an merchandise for $a hundred, then you definately have a damaging financial business enterprise account and an $a hundred merchandise. that's believed that in case you combine each and all of the project, antimatter, beneficial and damaging capability interior the universe, your end effect is 0. This has not something to do with evolution. i think of you will discover that there are various monkeys and apes that are extra clever than you. Chimps have been considered to seek in organised packs utilising each and every chimp's strengths and weaknesses. in case you learn evolution and abiogenesis, you will see that it has not something to do with possibility. you're the two trolling or uneducated. Sorry, uncomplicated actuality, no offence meant. Clocks do not make toddler clocks. it is fake good judgment and has been disproved one thousand situations. you elect a clock and not utilising a clockmaker? Our planet revolves around the sunlight throughout the time of a series time for which we are able to correctly set a three hundred and sixty 5 days long clock which we call a calendar. The earth spins at a series velocity to which we are able to set our watches by. this might properly be a 24hr clock. we are surrounded by clocks that are actually not made by clockmakers. the finished arguments are previous and have been shown fake. yet tell me, what info might you settle for? i think that there is not any.
