Canary Broom Genista canariensis

Early-season nectar — Flowers in a late-winter / early-spring window when few other plants in our catalog bloom — valuable early forage for pollinators (relative to our catalog's bloom coverage).

Canary Broom is an introduced perennial tree, found in the lower 48 states. It grows to 5 ft and blooms Mar – Apr.

More about this plant

Genista canariensis is a species of flowering plant in the legume family Fabaceae, known by the common names Canary broom, Canary Islands broom or florist's genista. It is native to the Canary Islands, but it grows as an introduced species in mainland Europe, especially Spain, and on other continents. It has been introduced to California and Washington State in the US. This is a vigorous upright evergreen shrub growing to 3 m (9.8 ft) tall by 1.5 m (4.9 ft) broad, with hairy green stems. The leaves are made up of oval-shaped blue-green leaflets each up to a centimeter long and densely hairy on the undersides. The raceme inflorescence holds up to 20 bright yellow pea-like flowers. The fruit is a legume pod one to two centimeters long containing several dark brown seeds. Wikipedia →

❧ Caterpillar hosts ~4 caterpillar species

Genista supports ~4 caterpillar species.

Native butterfly & moth caterpillars are the base of the terrestrial food web — most songbirds rear their young almost entirely on them. As a host for native Lepidoptera this is a modest genus for introduced plants — native genera typically support far more.

How we know this (1) Methods & honest limits
Photosynthesis Direct fact

A recorded categorical fact: each species is tagged C3 (standard), C4 (heat/water-efficient) or CAM (succulent, night-time CO₂ uptake) — or a facultative combination. We only show a trait card for the noteworthy C4/CAM cases; C3 is the unremarkable majority, kept in the data but not surfaced as a card.
