What’s the difference between bog plants and marginal plants?

Bog plants grow best in soil that is constantly wet, but they prefer not to have water above the soil level.

Marginal plants can grow in water that is up to 6 inches (15 cm) above the crown of the plant, so they can be planted in shallow areas of the pond or in a pot that is placed on the bottom of the pond.

10 BEST BOG PLANTS FOR PONDS

1. Iris (Iris germanica)

Irises are hardy perennials with beautiful flowers in shades of purple and blue.

They grow well in full sun to partial shade and bloom from early spring.

As well as beautifying the pond, they also help to stabilize the bank and cycle nutrients to keep your pond healthy.

Irises are frost tolerant and can reach 2 to 3 feet (60 to 90 cm) in height.

They can be divided after flowering by discarding the middle section and replanting the outer sections.

They usually live for only 3 to 4 years but they re-seed readily so you’ll have plenty of new plants popping up in your garden.

4. Tropical Pitcher Plants (Nepenthes species)

Pitcher plants thrive in moist, swampy areas so they’re ideal bog plants for ponds.

They’re carnivorous plants and use a pouch of sticky sap to trap insects, small lizards, worms and spiders.

Pitcher plants are commonly found in areas with nitrogen-poor soil and get their nitrogen from the insects and other creatures once they are digested.

They grow best in warm, humid areas but in areas with low humidity they can be misted regularly.

Watercress is a nutritious water plant that can be grown at the edge of a pond or in a pot submerged in the water.

It’s a perennial plant that grows best in warm weather and it will die down a bit during cold weather. 

Watercress plants can be propagated from cuttings or seed.

7. Taro (Colocasia esculenta)

Taro is a water plant traditionally grown in swampy areas in Southeast Asia, so it’s an ideal bog plant.

You can plant Taro at the edge of a pond or water feature but the leaves need to be above the water level.

Taro is best suited to warm, tropical climates but it can be grown in cooler climates if it’s overwintered indoors.

8. Horsetail (Equisetum arvense)

Horsetail grows from underground rhizomes and reproduces from spores.

The reeds grow well around the edge of a pond but they can spread quickly and take over the pond.

If you have a small pond it’s best to grow Horsetail in pots so that it doesn’t get out of hand, otherwise you can cut it back in fall to stop it from spreading.

9. Cattail (Typha latifolia)

Cattail is a handy bog plant that helps to filter pond water, provides food and nesting materials for birds and prevents soil erosion.

It spreads easily by underground rhizomes as well as seed, so it’s a good idea to cut off the seed heads before fall.
