Care Guide
Planting
Plant your Island Snapdragon in full sun for maximum blooms, though part shade works too (especially if you're inland where it gets hot). It's not picky about soil - it tolerates a variety of types as long as drainage is good, so amend heavy clay with compost or plant on a slight slope. Space it with room to sprawl since it grows fast and can reach 3 feet tall. Plant in spring for best establishment.
After Planting
Water twice a month during summer once the plant is established, then back off - this is a low-water native that actually prefers dry conditions. The #1 mistake is overwatering; let the soil dry out between waterings and resist the urge to baby it. It's evergreen and will bloom nearly year-round under good conditions, and it's cold-hardy to 30°F, so Bay Area winters won't hurt it. Prune lightly after flowering if it gets leggy, but this easy grower doesn't demand much attention.

Birds
Primary nectar source during Apr-Jul bloom; critical for breeding season energy demands
Spring migration staging and breeding season nectar; Apr-Jul blooms align with nesting period
Insects
Spring through early summer foraging during bloom period
Spring-summer bloom period; key pollinator and nectar forager
Spring-summer adult nectar source during bloom period
Apr-Jul foraging during peak bloom; supports colony growth season
Spring-summer pollen and nectar collection during bloom
Hosts herbivorous prey insects during spring-summer; indirect support
Late spring through summer foraging; secondary pollen source
Mammals
Post-bloom seed dispersal and consumption; caches seeds for overwinter use
