Bog plants, or terrestrial plants, are those which are perfectly satisfied with their roots in saturated, moist soil, but prefer to keep their stem and leaves dry. This will vary depending on the cultivar that you choose. Their flowers and foliage above the surface of the water provide a valuable source of shelter and food for insects, birds, and other critters. While their submerged parts are a perfect place for fish to lay eggs or seek shelter.
When choosing a particular variety, make sure to compare its needs and standards to your conditions. Will it be able to last through your winters? Is your water the right quality for it to thrive?
- Venusta (Queen of the Prairie): These are tall, pink perennial plants that bloom from early to late summer. They can grow up to 8 feet high and usually spread about 3 to 4 feet wide. Venusta thrives in moist soil -- these plants may struggle in times of drought or in particularly warm summers. Their pink blooms are a beautiful addition to a pond and will attract butterflies and other kinds of pollinators.
- Purple Loosetrife: These perennials are excellent for attracting bees and butterflies. Purple loostrife grows up to 4 feet tall and a few feet wide. They grow gorgeous pink, purple, and magenta blooms all throughout the summer. Be aware however, that this species is incredibly invasive in North America. One mature plant can produce more than 2 million seeds each year. Look for sterile cultivars or take great care in monitoring and grooming these plants.
- Astilbe Fanal: These perennials boast gorgeous dark crimson plumes throughout the summer. These are very tolerant to shade and resistant against pests, diseases, deer, and rabbits. These plants prefer part to full shade but can withstand full sun in areas where the summers don’t get too hot and there’s lots of moisture. These are excellent flowers for gifting or drying for preservation.
- Giant Rhubarb: These large plants are often chosen for their huge deep green leaves that can grow up to 6 feet across. These perennials can grow up to 10 feet tall and over 14 feet in width. These do best in very moist conditions, such as around the edges of a pond. These are resistant to most pests and diseases, though it's recommended to keep an eye out for slugs, snails, and other leaf-hungry critters. If damaged or dying leaves appear, remove them when you see them.
- Calla Lily: These are semi-evergreen perennials that show off huge, white trumpet-like flowers. They are native to Southern Africa, and can grow up to 3 feet tall and 2 feet wide. Be cautious however, as calla lilies are toxic to dogs, cats, horses, and even humans if ingested.
