A quick guide to pond plants

Ontario Gardener Magazine - - LOCAL DIRT -

Mar­ginal or bog plants: These plants grow in soil, usu­ally from pots, that are cov­ered by sev­eral cen­time­ters of wa­ter. They grow along the edges of ponds. e.g. iris, marsh marigold, cat­tails, bog bean, wa­ter plan­tain and ar­row­head.

Deep-Wa­ter: These plants are placed in deeper wa­ter, usu­ally 12 inches deep, rooted in their soil con­tain­ers. Leaves and flow­ers grow on or above the pond’s sur­face. e.g. wa­ter lily and lo­tus.

Float­ing: Plants that float on top of the wa­ter and do not use soil. e.g. lily pads, duck­weed, wa­ter let­tuce, and salvinia. Sub­merged: These plants grow en­tirely un­der the wa­ter and help pre­vent al­gae growth. They are also called oxy­gena­tors. Some root at the bot­tom of the pond while other va­ri­eties do not. e.g. horn­wort, ba­copa, lud­wigia and dwarf sagit­taria. Main­te­nance 101: Pull out plants that are be­com­ing to vigourous in the sum­mer and cut back dead growth in spring.

Al­ways check to see if there are any in­va­sive species that you should avoid; they can take over your pond very quickly. S
