Aquilegia canadensis L.
Family - Ranunculaceae
Stems - To +60cm tall, multiple from base, branching above, red to green, herbaceous, thin, glabrous to glandular pubescent in upper portions, sparsely pilose below.
Leaves - Basal leaves on
long petioles, biternate. Petioles to +10cm long, sparse pilose to glabrous.
Cauline leaves becoming sessile above. Leaflets lobed, deep green and glabrous
above, glaucous below with some pubescence near base or not. Ultimate divisions
obtuse at apex, with main veins coming together at apex forming tiny white
tip.
Inflorescence - Single flowers from leaf axils on long peduncles, nodding.
Flowers - Petals 5, spurred,
yellowish at tip red for rest of length, +/-4cm long, expanded upper lip
to 7mm broad. Sepals 5, reddish, yellow at apex, alternating with petals,
to 2cm long, lanceolate. Stamens +20, of different lengths, those closer
to pistil longer than outer. Filaments to +1.7cm long, flattened and expanded
at base, glabrous. Anthers yellow, 2mm long and broad. Styles to 1.3cm
long, filiform, glabrous. Ovaries 4, 5mm long, tomentose, pale yellow-green.
Fruit - Follicles to 3cm long, beaked.
Flowering - April - July.
Habitat - Rocky ledges, rocky slopes, low woods. Also cultivated.
Origin - Native to U.S.
Other info. - The spurs of
the petals contain nectaries and are very attractive to insects equipped
with long proboscises. This and other species of Aquilegia
are highly cultivated and easy to grow.
In Italian "Aquila" means "Eagle"
and indeed the genus is so named because of the talon shaped spurs of the
petals.
Steyermark lists two forms for
the plant in Missouri. Form canadensis, (pictured
above), has the typical red and yellow corolla. Form flaviflora
(Tenny) Britt. has a corolla which is completely yellow. This form
is rare. Some cultivated forms have white or pink corollas and can
be double flowered also.
