Small Tarweed

Small Tarweed is an upright annual that grows about 1.5 feet tall, with hairy stems and tiny leaves. An array of subtle, small yellow flowers bloom throughout the spring and summer, providing nectar and pollen for butterflies moths, and bees. It is also a likely larval host plant of the Spotted Straw Sun Moth and Small Heliothodes Moth.

Like other tarweeds, this species has glands at its base that produce sticky yellow resin.

This is a small but mighty addition to pollinator gardens and native wildflower gardens.
