Lysimachia terrestris is a perennial herb 40-80 cm tall, stem bluntly 4-sided, hairless, branched above, leaf scars leaving bamboo-like joints around stem; small, succulent bud-like bulblets form late in season in some leaf axes, often reddish, dropping to ground and forming new plants the following season.
