The best time to plant untreated lupine seeds outdoors is between September-November. Plants grown from seed will bloom their first year. Pinch off spent flowers to prolong the blooming period.
Light: Full sun is preferred. Lupine can grow in part shade, but flowering will be lessened. Soil: Lupine needs well-draining soil above all else.
Lupines contain alkaloids that are known to be toxic to humans and animals. Though toxicity has been predominantly noted in livestock, the danger of poisoning in dogs is a possibility.
