Care Guide
Planting
Plant Pacific Pea in full sun with fast to slow-draining soil - it tolerates sandy or clay loam, so you have flexibility here. This native vine climbs through other plants naturally, so give it a structure or companion planting to scramble through. The Bay Area's mild winters mean you can plant in fall or early spring; the plant flowers winter through spring, so fall planting gives you blooms sooner.
After Planting
Water very sparingly once established - this is a drought-tolerant native that prefers dry conditions, so err on the side of underwatering rather than overwatering. The #1 mistake is treating it like a typical garden plant and watering it regularly; in the Bay Area, summer water is usually unnecessary. Year one, water occasionally during establishment, then back off substantially. The plant is evergreen, so you'll have foliage year-round to enjoy between its purple or white flower clusters.
