Bog Gardens need plants that are going to withstand standing water without disease or dying. These plants need to be hardy enough to survive these conditions and thrive from them. A love of water is definitely a must for these plants. Here is a look at the periwinkles, the vinca major and the vinca minor, and how they function in a bog garden environment.
Bigleaf Periwinkle
The Bigleaf Periwinkle (vinca major) is an herbaceous groundcover, perennial, evergreen, and fast growing. Covered in slightly larger blue flowers than vinca minor, it slinks round the ground with stems up to a foot in height. They will flower throughout the spring and a bit throughout the summertime as well. They have lovely shiny foliage. Bigleaf periwinkle is from Asia, Africa, France, Italy, and Europe.
To plant, you will need full sun or partial shade for the gardening plot, with any soil type being fine. Preference to better growth will occur when the soil is rich and moist, although it will do fine in zones seven to nine in the USDA map. To propagate any periwinkle you will need to do cuttings or a shoot piece that has already rooted.
All vinca species are poisonous if taken internally, so care should be taken when this plant is around children, livestock, or pets.
Common Periwinkle
The Common Periwinkle (vinca minor) is an evergreen, woody vine that is typically a ground cover. It too is fast growing. It has violet blue flowers that are funnel in shape. They will produce blooms throughout spring and periodically through the summer. It can also have different cultivars that produce white, burgundy, or yellow blooms. It is from Spain, France, Russia, Africa, Asia, and Europe.
To plant, you will need to have full sun for the most flowers or shady spots for the best in ground covering. It will love to be set in moister soils than the drier ones. It is for the USDA zones of four to nine. The vinca minor is the hardiest of all the periwinkles. To propagate you will need to divide the shoot pieces that have already rooted.
This causes stomach issues when any of the plant is taken internally. Take care in placing it around livestock, pets, or children.
Bog Garden Periwinkles
Periwinkles in their love for water will go well with any bog garden. While both the vinca minor and the vinca major are both very similar, there are slight differences that may make the gardener prefer one over the other.
