- 🌱 Yankee Point is a prostrate variety that typically grows only 1-2 feet tall but spreads 6-8 feet wide, making it excellent for covering large areas with minimal vertical growth.
- 🌱 Ceanothus species have nitrogen-fixing root nodules similar to legumes, allowing them to thrive in poor, nutrient-depleted soils without supplemental fertilizer.
