Nuttallanthus canadensis syn. Linaria canadensis
Canada Toadflax
With clusters or spikes of flowers in a wide range of colours, toadflaxes are popular plants for borders and rock gardens. Among this genus of annuals, biennials and herbaceous perennials are plants that flower over long periods, often from mid-summer into autumn. The perennial species tend to be short lived but they often self-seed. Most species are hardy but L. genistifolia ssp. dalmatica and L. triornithophora will not withstand long periods below freezing. 'Canada Toadflax' is an annual or biennial, native to eastern Nprth America, Spring-flowering plant, with blue to purple flowers

Planting young plants
From Early Spring TO Early Spring
Plant young plants in spring in well drained soil in an open, sunny position. L. alpina prefers gritty soil in a raised bed or in a pocket in a rock garden. Move self-sown seedlings to new positions in late winter or early spring.
Propagation
From Early Spring TO Early Spring
Sow the seed of annual species in spring, thinly where the plants are to flower. Sow the seed of perennial species in winter or early spring in a cold frame. Alternativelly, divide perennial species in spring or take soft wood cuttings in spring or early summer.
Flowering
From Early Summer TO Early Autumn
The two-lipped, little snapdragon-like flowers appear from early Summer right through to early Autumn. The flowering period is prolonged by frequent dead-heading
