Broadleaf Weed – Bulbous Buttercup

(Ranunculus bulbosus)

Also referred to as Yellow Weed, Blister Flower, Gowan and Bulbous Crowfoot, Bulbous Buttercup is a tufted perennial weed that thrives in pastures, hay fields, lawns and landscaping. Ranunculus bulbosus can be found throughout much of the continental United States.

Identifying Bulbous Buttercup -

Bulbous Buttercup can be identified by its stems that are hairy at the base and sometimes hairy above, forming a basal rosette of three-parted leaves. The middle lobe is on a stalk, the two lateral lobes are attached at the base on the petiole. The basal and lower stem leaves are on long hairy petioles. Bulbous Buttercup can grow over winter as corms but reproduction is by seed.

In bloom, Bulbous Buttercup features single, bright yellow flowers occurring at the ends of stems, consisting of 5 to 7 petals.

Bulbous Buttercup Control -

Bulbous Buttercup can typically be prevented by proper turf management practices. Good watering and mowing habits will encourage a thick, lush bed of turf which will protect your lawn.
