Enjoy canary yellow spring flowers above 3' to 4' vertical green foliage. Yellow Flag iris is very hardy and a strong grower. Plant in a large container, as the rhizome grows fairly fast and large.

Reaches 12" - 24" in height. Blooms spring and early summer.

Generally found along wetlands, streams, rivers or lakes in shallow mud or water, this hardy plant will also tolerate drier soil and high soil acidity. Gardeners who often use this iris as an ornamental pond plant value the yellow flowers that bloom in the summer. 

However, it can quickly become invasive, and gardeners must beware of this in order to provide the most appropriate flag iris care.

PLANTING BOG PLANTS

Plant these as you would tropical lilies, making sure that you don't cover the crown of the plant. Most all of the bog plants that we sell come in 4" pots. Care should be taken when removing the plants from these pots. If the roots of the plant are growing out of the net pots, using a pair of scissors, carefully cut the net pot away and gently remove the plant, saving as many roots as possible. 

Place the plants in a shady area for them to adjust to the sun, wind and outdoor environment, as most of the plants are coming out of a greenhouse and need a couple of days to adjust to being outside. Bog plants after being planted in their new pots prefer moist soil until established and should only be in water deep enough to keep the soil moist. Once they are established and growing heartily, the water above the top of the pot can be as deep as 1/2" to 3", depending on the size of the plant.
