Chief, Pride-of-Ohio, American Cowslip, Roosterheads, Birdbills,
Johnny Jump, Shuttle Cocks. These are some of the picturesque
common names for Dodecatheon meadia, known in these parts

Dodecatheon
comes from the Greek and means 12 gods. The name was first
used by Pliny for the primrose, which was thought to be
under the care of the 12 principal Greek gods. Linnaeus
used it for the shooting star, a mostly North American flower
in the primrose family. The species name refers to Richard
Mead (1673-1754), an English doctor who botanized in Virginia,
the Carolinas, Georgia, and Florida in the early 1700s.
There
are 30-50 species of shooting stars in the world, depending
on who is doing the counting. At least one is from the arctic
of northeastern Asia. Most are from western North America,
often of arctic or alpine tundra. Dodecatheon meadia is
the largest, growing up to two feet or more in height and
having up to 30 flowers in its inflorescence. The leaves
are up to three inches wide and eight or so inches long.
A reddish patch at the base gradually narrows to a red stem.
The leaves form a basal rosette and appear early in the
spring. The naked flowering stalk is topped by a terminal
umbel of drooping flowers that range from white to rose
pink in color. There are five pointed anthers fused into
a central point from which the five petals bend backwards
so the flowers look like badminton shuttlecocks, comets,
or shooting stars.
They
are pollinated by bumblebees and bloom from mid-April through
June when the leaves completely disappear. The seed capsules
turn upright with their five sepals forming a star opening
from which the multitude of tiny seeds shake out whenever
the wind or passing animals nudge them.
Midland
shooting star has the widest ecological amplitude of all
the shooting stars and can be found temporarily underwater
in soggy meadows or on bone-dry goat prairies. It grows
in prairies, woods, oak savannas, rocky hillsides, and even
in calcareous fens ranging from Washington, D.C. and Pennsylvania
westward to Wisconsin, Arkansas, and Texas, then eastward
to Alabama and Georgia.
Shooting
stars are truly ephemeral, lasting only five-to-eight weeks
in early spring and disappearing by July except for their
ripening seed pods. The following year's flower buds are
produced by the end of the spring growing season and contractile
roots draw them down into the soil to protect them from
summer's heat and drought, trampling, and prairie fires.
Viable
seeds scattered and raked into prairie soil after a fire
take about six years to produce a plant big enough to notice.
A few plants may flower by their seventh year.
The
Village of Barrington, in a nod to native beauty, voted
shooting star as its village flower.
