Ludwigia alternifolia

Common Name(s):

Phonetic Spelling

Description

Rattlebox is a North American wildflower found in wet areas as swamps, stream banks, ditches and pond edges. It prefers acidic, sandy, moist to wet soils but does have some tolerance for other soils. Flowers appear in summer for 2-3 months and the delicate yellow blooms last for a day or less. These are followed by squarish seed capsules that rattle when shaken. They are pollinated primarily by bees. Plant in rain or water gardens or at stream and lake edges.
