Fun Facts
- 🌱 Ericaceous plants have a unique mycorrhizal relationship with fungal partners called ericoid mycorrhizae, which help them extract nutrients from extremely acidic, nutrient-poor bog soils where other plants cannot survive.
- 🌱 Cranberries can produce fruit for over 100 years in commercial bog settings, making them one of the longest-lived fruit-bearing plants in cultivation.
- 🌱 Some bog ericaceous plants like sundews and pitcher plants are carnivorous and supplement their nutrient intake by digesting insects, a unique adaptation to nutrient-poor bog conditions.
