Description
 
 

Bladder campion is a 8 to 32 tall, erect, short-lived perennial, that rises on several stems from a stout taproot. When in flower the plant tends to lean to one side under the weight of the flowers.

The stems are erect or reclining on the ground at the base then upright. They are branched, rarely unbranched. They are usually hairless and are covered with a whitish, waxy coating (glaucous).

Stem leaves are in opposite pairs. They are oblong to inversely lance-shaped with the attachment at the narrow end, ¾ to 3 long, less than ¼ to 1 wide, smaller near the inflorescence. They have a rounded, almost clasping, base. They taper gradually to a pointed tip with straight or concave sides along the tip. They are attached to the stem without a leaf stalk. They are hairless on the upper and lower surfaces. The margins are untoothed.

The inflorescence is open, much-branched cluster in which each axis produces an opposite pair of lateral axes. There are 5 to 40 flowers in the inflorescence.

Some plants have both male and female flowers. Other plants have female flowers only. Both flowers are to ¾ wide when fully open, and are on stalks that are less than ¼ to 1 long.

The sepals are fused at the base into a tube (calyx) terminating in short lobes. The calyx is to ½ long when in flower, ½ to ¾ long when in fruit, inflated, ¼ to ½ wide, and is not contracted at the mouth or the base. It is pale green, rarely purplish, papery, hairless, and smooth, not ridged. There are 20 obscure, equal veins with a network of veins between them. The veins are green at first, then become pinkish.

The petals are white, about two times longer than the calyx. They can be slightly indented at the tip, two-lobed, or deeply two-lobed and appearing as 10 petals. They are inversely egg-shaped with the attachment at the narrow end, horizontally spreading, with a stalk-like narrow base (claw). The flowers are fragrant. They open during daytime. On male flowers 10 stamens protrude beyond the calyx. Female flowers have 3 styles which are 2 times longer than the calyx.

The fruit is a green, hairless, egg-shaped, 3-chambered capsule the same size as the calyx, with 6 teeth at the top.

Similar Species

 
 

The pinkish swollen calyx with its network of veins distinguishes this plant from all other Silene species.

Balkan catchfly (Silene csereii) has long, raceme-like primary branches in its inflorescence. The calyx is smaller, constricted at both ends, and only slightly inflated. It has 10 long and 10 short veins and does not have an obvious network of veins between them. The stalks of the stamens that support the anthers (filaments) are purple.

Drummond’s campion (Silene drummondii var. drummondii) has narrow, wide stem leaves.

Night-flowering catchfly (Silene noctiflora) male and female flowers appear on the same plant. The flowers open at night. The fruit has 6 teeth at the top.

Starry campion (Silene stellata)stems are unbranched. The leaves are in whorls of 4. The petals have 4 to 12 frilly lobes.

White campion (Silene latifolia ssp. alba) stems and leaves are hairy. The stems are covered with minute, short, glandular hairs near the top. Male and female flowers are borne on separate plants. The calyx is prominently veined, and hairy, the veins often accented with purple. Female flowers have 5 styles which project barely beyond the calyx. The flowers open at night. The fruit has 5 upright teeth (appearing as 10) at the top.

Subordinate Taxa

 
 

Several subspecies of Silene vulgaris have been described. Plants of the World Online (POWO) and World Flora Online each recognize five subspecies (including the nominate subspecies), none of which occur in North America. Only ssp. vulgaris, the nominate subspecies, occurs in North America.

Some authoritative sources, including ITIS, GRIN, USDA Plants, and Flora of North America, often omit the subspecies or variety in the scientific name if the nominate species or variety is the only one occurring in north America.

Glossary

Calyx

The flower cup. May be the group of outer floral leaves (sepals) collectively, or a tube with lobes.

 

Clasping

Describing a leaf that wholly or partly surrounds the stem but does not fuse at the base.

 

Claw

A stalk-like narrowed base of some petals and sepals.

 

Glandular hairs

Hairs spread over aerial vegetation that secrete essential oils. The oils act to protect against herbivores and pathogens or, when on a flower part, attract pollinators. The hairs have a sticky or oily feel.

 

Glaucous

Pale green or bluish gray due to a whitish, powdery or waxy film, as on a plum or a grape.

 

Raceme

An unbranched, elongated inflorescence with stalked flowers. The flowers mature from the bottom up.
