The stem is woody with several branches. The leaves are a few centimeters long and are divided into 3 to 7 narrow leaflets. The inflorescence atop each stem branch is a spike up to 7 cm (2 + 3 ⁄ 4 in) long containing many purple flowers. The fruit is a legume pod containing 1 or 2 seeds. [8] The Latin specific epithet purpurea means purple. [10]
The flowers are tubular in shape, produced on a tall spike, and vary in colour with species, from purple to pink, white, and yellow. The name derives from the Latin word for "finger". [4] The genus was traditionally placed in the figwort family, Scrophulariaceae, but phylogenetic research led taxonomists to move it to the Veronicaceae in 2001. [5]
The leaves are broad and oblong-lanceolate, forming a rosette about the base of the plant and surrounding the flower spike. They are fleshy and bright green, and can be up to 15 cm long. The inflorescence is densely covered with up to 50 flowers. The sepals and upper petals are violaceous or purple (hence the Latin name purpurea of the
Digitalis purpurea is an herbaceous biennial or short-lived perennial plant. The leaves are spirally arranged, simple, 10–35 cm (3.9–13.8 in) long and 5–12 cm (2–5 in) broad, and are covered with gray-white pubescent and glandular hairs, imparting a woolly texture.
The plants have tall spikes of purple flowers resembling bottle brushes or feathers that grow 1–5 ft (0.30–1.52 m) tall. The species grows in hardiness zones 3 - 8, [ 4 ] stretching from the Midwest to the East Coast, eastern and western Canada.
The flowers are produced on a tall spike, each flower 1–1.5 centimetres (0.39–0.59 in) long, most commonly blue to purple in wild plants. The flowers are mostly visited by bumblebees. [5] The polyphyllus variety in particular make up a great number of the hybrids which are generally grown as garden lupines, which can vary dramatically in ...
