kle-MA-tis ( or KLEM-a-tis) ar-MAN-de-i
Native to (or naturalized in) Oregon:
- Broadleaf evergreen vine, fast growing to 20 ft (6 m). Leaves opposite, pinnate compound, 3 leaflets, leathery, glossy dark green, 7.5-15 cm long, oblong-lanceolate to ovate, pointed, droop downward, margin entire. Flowers white, 5-6.5 cm long, 4-7 sepals (the showy parts), fragrant, in large branched clusters in spring. Cultivars may have white or pinkish flowers (e.g, 'Hedersonii Rubra'). Flowers are followed by clusters of plumed seeds, considered attractive by some.
- Sun to part shade. Clematis, in general, do best if roots are in cool soil (protected from sun) and tops in full sun. They prefer rich, loose, well-drained soil high in organic matter; a pH of 6-7.5 is recommended by some whereas others advocate an alkaline soil. Provide support. Needs pruning after flowering to avoid build up of tangled dead stems in the inner parts of the vine.
