Kinnikinnik Kinnikinick

Kinnikinnik spreads as an evergreen ground cover that rarely exceeds one foot in height, its prostrate stems rooting where they touch soil to form dense, creeping mats. You recognize it by its small, lustrous dark green obovate leaves clustered along finely textured reddish stems that exfoliate to reveal glossy bare wood on older growth. In spring, delicate white flowers blushed with pink emerge in nodding clusters; by late summer, the plant produces bright red fleshy berries attractive to bears and birds alike, justifying both the botanical name (uva-ursi: bear's grape) and its place in native gardens across the circumboreal northern hemisphere. The plant's trailing stems with periodic rooting nodes allow it to spread 3 to 6 feet wide while hugging the ground. Bark exfoliation on older stems creates subtle textural interest even when not in bloom, rewarding close observation.

Kinnikinnik succeeds in full sun to part shade with well-drained, sandy or infertile soils; it dislikes compacted earth and heavy clay unless significantly amended. This plant proves difficult to transplant, so establish it correctly on the first attempt in poor, acidic soils that would challenge other broadleaves. In year one, water moderately (1 to 2 gallons 1 to 2 times per week during summer); once established, reduce frequency to every 7 to 10 days during hot weather and stretch intervals further for drought-stressed plants. PNW records note susceptibility to black root rot, leaf gall, leaf spot, phytophthora dieback, and rust; avoid waterlogged sites to minimize root diseases. Aphids and root weevils may visit; the manzanita leafgall aphid sometimes creates conspicuous leaf distortions. Several cultivars ('Massachusetts', 'Point Reyes', 'San Bruno Mountain', 'Emerald Carpet', 'Vancouver Jade') offer hardiness and vigor variations; 'Emerald Carpet' tolerates more shade than the species while 'Vancouver Jade' turns red-bronze in winter for seasonal interest.
