Yellow Rattlebox

Description:

This plant has an erect stem that bears stalkless, yellow flowers in a leafy one-sided spike. The calyx is inflated when in fruit.

Habitat:

Spotted in a large meadow bordering the coast.

Notes:

Yellow rattlebox is hemi-parasitic on pasture grasses, which means that its roots attack the roots of other plants and then suck the life out of them. If enough yellow rattlebox grow in a meadow, they can destroy the other grasses in it.
