Chiastophyllum oppositifolium ‘Jim’s Pride’ – This relative of the Sedum has the same thick green succulent-like foliage and is also generously edged in pale creamy-yellow. It is evergreen in coastal BC and bears pendulous bead-like yellow flowers on stems just above the foliage from May to June. Native to the Caucasus mountains. Grows 4 to 6″ high by 12″ wide. Hardy to zone 6.
Anthriscus sylvestris ‘Ravenswing’ – The ultimate filler plant for the back of the perennial or mixed border with dramatic purplish-black stems and foliage. Delicate umbels of contrasting Queen Anne’s Lace-like flowers are borne from mid spring into summer. This biennial or short-lived perennial will self-seed if not deadheaded. Grows 24-36″ high by 12-24″ wide. Zone 6.
Polemonium caeruleum BRISE D’ANJOU (syn. ‘Blanjou’) – This sport of Jacob’s Ladder (discovered in France) has intricate ferny foliage – all of it generously edged in creamy-yellow. Contrasting violet-blue flowers are borne on terminal clusters from late spring into summer. Cut back faded flowers to encourage a repeat bloom. Grows 18-24″ high and wide. Hardy to zone 4.
Stachys byzantina ‘Cotton Boll’ – This variety of Lamb’s Ear features large 4 to 6″ long leaves covered in velvety silvery-white hairs. Clusters of silver balled flowers that are borne on 18″ stalks in summer give this cultivar its name. ‘Cotton Boll’ is reported to tolerate our often humid coastal BC summers well. Drought tolerant. Grows 4-6″ high by 24″ wide. Hardy to zone 4.
Artemesia vulgaris ‘Oriental Limelight’ – This perennial has an invasive reputation so unless you have plenty of room, grow it in a large container. That being said, the finely cut leaves are generously variegated in pale yellow and cream making for a beautiful display. This is primarily a foliage plant, so I cut out the insignificant flowers. Grows 2-3′ high by 30″+ wide. Zone 4.
