Silene latifolia Poir. ssp. alba (Mill.) Greuter & Burdet Lychnis alba Mill. Lychnis ×loveae B. Boivin Lychnis vespertina Sibth. Melandrium album (Mill.) Garcke Silene alba (Mill.) Krause Silene pratensis (Raf.) Gren. & Godr. Bladder campion
Bladder campion is a European native, brought to North America, where it is now a common weed. Identification: Plants are 18-42" (45-106 cm) tall, with hairy, jointed stems. Leaves are oval to narrow, 4" (10 cm) × ¾" (2 cm). Flowers are white or pink, ¾-1" (1.9-2.5 cm) in diameter, with five deeply notched petals. Flowers open in the evening and close by noon. The calyx at the base of each flower is bulbous, like a little balloon, sometimes called the bladder. It is lined with ten prominent dark green or purplish “nerves.” Seeds are small, rounded, and rough. White campion closely resembles bladder campion: |
