How to Start It
★ Recommended for beginners
Surface-sow indoors 6 weeks before last frost or direct-sow in spring; thin to 45 cm. Wear gloves when handling seedlings.
IMPORTANT: rue's sap can cause painful, blistering skin burns when you then go in the sun (phytophotodermatitis) — always wear gloves and long sleeves, and handle on cloudy days. It's grown mainly as a blue-grey ornamental and traditional pest-repellent, not for eating.
