Care Guide
Planting
Plant Blue Dips in full sun in a spot with fast-draining soil - sandy or coarse-grained soil is ideal. They bloom March through May, so plant in fall or early winter to establish before flowering. Space them in drifts for impact, as these are small bulbs (1-2 feet tall). They're native to the Bay Area and surrounding regions, so they'll appreciate conditions similar to their natural habitat.
After Planting
Water moderately during the growing season and keep the soil moist through summer. Once established, Blue Dips need very little water - they're drought-tolerant and prefer drier conditions, so hold back on watering after bloom ends and the foliage yellows. These are deciduous bulbs that go dormant in summer; this is completely normal and not a sign something is wrong. The biggest mistake is overwatering or planting in heavy clay soil where water sits around the bulbs, which causes rot.
