The glossy leaves are arrowhead-shaped. Water Calla is an ideal background plant for a pond or tub garden.
The large white blooms are truly magnificent. The plant grows about 2' tall and the blooms rise up near or above he top of the foliage. They need to be placed in the pond so that there is no more than an inch or so of water over the top of the pot.
In lesser zones than 10 simply remove them from the pond and place them in a sunny window in a saucer kept filled with water.
Given enough light and cooler home temperatures they will bloom most of the winter indoors too.
Blooms in cooler water.
Calla can be potted, or the rooted ends tucked into the rocks of a streambed or water fall.
Water Calla is hardy zone 10
