Santolina chamaecyparissus, cotton lavender

Family: Asteraceae

Description:

Slightly disorganized mounds of gray foliage sport a profusion of yellow composite flowers. The characteristic disk-shaped flowers do not have any rays and are irregular in size. This evergreen sub-shrub remains relatively low to the ground, not exceeding 50 cm. Foliage is aromatic

Growing conditions:

Santolina chamaecyparissus is best grown in dry, well-drained soil in a sunny location.

Suitable uses:

This mounding shrub is useful as an evergreen ground layer. Planting on a slope can both aid with drainage and prevent the mounding form from splitting. Planted with other mounding shrubs, such as hebes, can provide a nice formal echo. Alternatively, Santolina chamaecyparissus can be used for hedging, though this will inhibit summer floral displays.

Centaurea cyanus,corn flower

Family: Asteraceae

Description:

Azure blue flowers sit atop grey-green branched stems. Delicate, fan shaped petals extend from a cluster of central filaments. Bracts have a pronounced black edge. This species is known to grow within fields of wheat, flour or oats. As a hardy annual, Centearuea cyanus will die within one season, but will typically self-seed and re-sprout the following year. Flowering season lasts throughout the summer.

Growing conditions:

This plant prefers dry sunny locations and will not tolerate wet sites.

Suitable uses:

Centaurea cyanus works well in a wildflower mixture and can compete fairly well with grasses. In dryer climates it is known to be weedy, but is not a problem in the Vancouver area. The beautiful inflorescence contrasts nicely with orange.
