Helianthus gracilentus aka Slender Sunflower
Taxonomy ID: 13559
Helianthus gracilentus is in the daisy family, Asteraceae. Its home range runs from California into Mexico's Baja California Norte. The RHS accepts this name for the plant. It also lists it as not native to Britain or Ireland. This small shrub grows just a little wood. Its loose mound reaches about 3 feet (0.9 metres) tall. It can grow as wide as it is tall. This gives it a broad form, not an upright one. Gaps show between the leafy stems. The mound is open, not dense.
The gray bark has shallow grooves along its surface. Young twigs are red-brown and bear a coat of gray fuzz. The stems grow little wood, though they form a shrub. Leaves grow in pairs, on opposite sides of each stem. Each leaf is simple, not split into leaflets. The blades range from lance-shaped to somewhat egg-shaped. They reach 0.33 feet (0.10 metres) in length. Leaf edges may be smooth or have fine teeth. The top of each leaf is yellow-green. The paler side below bears small gland dots. Leaves may stay green or fall off late.
Bright yellow flower heads bloom from late spring through early fall. Each head looks like a daisy. It spans about 0.17 feet (0.05 metres). The blooms have a chocolate scent as well as bright color. Long stalks hold the heads at the tips of twigs. They lift the blooms well above the leaves. The heads stand clear of the loose mound. Yellow heads stand out against the pale leaves. This contrast gives the plant its look when in bloom. Its long bloom season runs from spring into the start of fall.
The fruit forms a group of small achenes. Each achene, a type of fruit, is about one-eighth of an inch long. Each bears two tufted hairs. These fruits are far smaller than the broad flower heads. The sources describe the plant's form and blooms. They give no guide to care in a garden. They do not state its light or water needs. Nor do they state soil needs or cold limits. They give no pest or disease account for this species. No evidence here confirms parts safe to eat or medicinal uses. Nor does it confirm safety for people or pets. The scent and raised yellow blooms are its main known garden features.
