Fun Facts
- 🌱 The common name 'Iceplant' refers to the distinctive crystalline-looking bladder cells on the leaves that contain salt and shimmer like ice crystals in sunlight
- 🌱 Lampranthus flowers are heliotropic, meaning they follow the sun throughout the day and close at night or on cloudy days, a behavior called nyctinasty
- 🌱 This South African native is highly salt-tolerant and thrives in coastal gardens where salt spray would kill many other plants, making it ideal for oceanfront properties
