Perennials to plant with conifers
While trees and shrubs don their fall colours, conifers stay green all year round, although some of them take on purplish hues in colder weather – some cyprus (Chamaecyparis thyoides 'Heather Burn', for example) and junipers (Juniperus horizontalis 'Wiltonii' and Juniperus horizontalis 'Plumosa').
These conifers make a good contrasting backdrop for plants with grey, silver or pale yellowish-green foliage that persists until the fall.

|---|---|
| Artemisia stellariana (Dusty Miller) | Silvery green foliage |
| Aurinia saxatilis (Basket of gold) | Grey foliage |
| Cerastium tomentosum (Snow in summer) | Silver foliage |
| Veronica incana (Silver speedwell) | Grey foliage |
