Broadleaf Arrowhead features dainty racemes of white flowers rising above the foliage from early to late summer. Its attractive textured pointy leaves remain green in color throughout the season. The fruit is not ornamentally significant.
Broadleaf Arrowhead is an herbaceous perennial with a ground-hugging habit of growth. Its medium texture blends into the garden, but can always be balanced by a couple of finer or coarser plants for an effective composition.
This plant will require occasional maintenance and upkeep, and should be cut back in late fall in preparation for winter. It has no significant negative characteristics.
Broadleaf Arrowhead is recommended for the following landscape applications;
Water Gardens, Container Planting, Bog Gardens
Broadleaf Arrowhead will grow to be about 24 inches tall at maturity extending to 3 feet tall with the flowers, with a spread of 4 feet. Its foliage tends to remain dense right to the ground, not requiring facer plants in front. It grows at a fast rate, and under ideal conditions can be expected to live for approximately 10 years.
This plant does best in full sun to partial shade. It prefers to grow in moist to wet soil, and will even tolerate some standing water. It is not particular as to soil pH, but grows best in rich soils. It is somewhat tolerant of urban pollution. This species is native to parts of North America. It can be propagated by division.
Broadleaf Arrowhead is a fine choice for the garden, but it is also a good selection for planting in outdoor pots and containers. Because of its spreading habit of growth, it is ideally suited for use as a 'spiller' in the 'spiller-thriller-filler' container combination; plant it near the edges where it can spill gracefully over the pot. It is even sizeable enough that it can be grown alone in a suitable container. Note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.
