Lance Leaf Tickseed is a native herbaceous perennial in the Sunflower family (Asteraceae). It can be found throughout Alabama. Lance Leaf Tickseed grows on roadsides, in pastures, in forest openings, and around rock outcrops. It is a perennial with short rhizomes, often forming clumps. The stems are erect to ascending, green in color, and pubescent to glabrous. The leaves are basal and cauline. The leaves are petiolate, lanceolate to elliptic in outline, simple or with 1-2 lateral lobes, and pubescent or glabrous. The stem leaves near the apex are often sessile or with very short petioles. There are usually 1-5 nodes below the inflorescence. Flowers are produced in heads. The heads are usually solitary on long (8-12 inches) peduncles at the apex of the stems. Each head has 8-10 yellow ray flowers that are toothed and 50-100 yellow disc flowers. The fruit is a winged achene. Lance Leaf Tickseed is extremely variable in appearance. It is commonly available from nurseries as either seed or plants. Lance Leaf Tickseed prefers a sandy well-draining soil in full sun. It can be used in a perennial bed or naturalized in a meadow. Several cultivars of this species are also available including one with only ray flowers. It can often spread widely from seed. To prevent this, remove the heads after the ray flowers fall. This will also promote additional flowering.--A. Diamond
