Fun Facts
- 🌱 Heliotrope gets its name from the Greek words 'helios' (sun) and 'trope' (turning), though compact varieties don't actually track the sun as dramatically as the name suggests.
- 🌱 The fragrance of heliotrope has been prized since Victorian times and was a favorite flower of Queen Victoria herself; it's often described as smelling like cherry pie or vanilla cookies.
- 🌱 Heliotrope contains alkaloids like heliotropine that can be toxic if ingested in large quantities, so while the flowers are technically edible, they should only be used as delicate garnishes in small amounts.
