Ivy takes its name from the climbing plant, long associated with fidelity and enduring attachment since it clings and persists through changing seasons. The name is commonly linked with quiet resilience -- growth that continues steadily rather than in sudden bursts, and a loyalty that holds even under difficult conditions.
Entrust the Sun when you are depressed because it means renovation, growth, and quick response. - Picatrix (Andalusia, ~1000.AD)
