Fringed loosestrife (Lysimachia ciliata) is a species of flowering plant in the Primulaceae family. It is an erect, herbaceous perennial growing to 120 cm (47 in) tall and 60 cm (24 in) broad, with opposite, simple leaves, and smooth, green stems. The star-shaped yellow flowers are borne in midsummer.[1] It is native to North America, including most of southern Canada and most of the United States except for the southwest. This plant is notable in that it is one of the few species of Lysimachia to bear elaiosomes, that is, to offer oil instead of nectar as a reward to pollinators.

It is also cultivated as an ornamental plant. It can be invasive, but new suckers can be removed easily to keep plant size under control. The most common cultivars of L. ciliata include:

  • L. ciliata 'Firecracker'
  • L. ciliata 'Purpurea'

'Firecracker'[2] has gained the Royal Horticultural Society's Award of Garden Merit.
