- 🌱 Eucalyptus greenery is highly aromatic and contains natural oils; some varieties are used in aromatherapy and have mild antimicrobial properties.
- 🌱 Ruscus (butcher's broom) has been used for centuries in European Christmas decorations and gets its name from its traditional use in meat shops to brush surfaces clean.
