Perennials

This grass has a remarkable tolerance for extreme climates and is not invasive. It displays soft, feathery green plumes during the summer, maturing into stiff, wheat-coloured spikes that last into winter.

It is generally used in large groupings towards the back of borders, but is also effective as a single plant that can be easily divided in spring. Prune down to the ground in March.

One of the most common native ferns, growing all over northern regions. Plants form a large, upright clump of big green fronds. In spring the unfurling fiddleheads are often harvested in the wild as a gourmet treat. Roots are spreading, and plants can form quite a large patch in time. Requires plenty of water through the summer, otherwise the foliage may become dormant. Cinnamon-brown fertile fronds push up from the centre of each clump in summer, and these remain attractive all winter long. Prune off dead foliage and fertile fronds in late winter. Deciduous.

Divide in August to September. Flowers are good for cutting, picked just as the buds begin to open.

This is a hybrid strain of Columbine that flowers freely. Plants have a compact habit, with the large blooms usually bi coloured in shades of blue, white, pink, red, rose or yellow. Flowers are attractive to hummingbirds.

Removing spent flowers will increase the blooming time. Columbines are relatively short lived, so allow some of the plants to go to seed and self sow. Leaf miners or sawfly may disfigure the leaves around flowering time, but simply trim off the unwanted foliage and the plants will grow fresh leaves.
