Fun Facts
- 🌱 Ruby Glow is a cultivar of Leptospermum scoparium, native to New Zealand and southeastern Australia, where it has been used traditionally by Māori peoples for wellness purposes.
- 🌱 The common name 'Tea Tree' comes from early European settlers who brewed the leaves as a substitute for black tea, not from any relation to the actual tea plant (Camellia sinensis).
- 🌱 The double-flower form is a selected cultivar trait; wild Leptospermum typically has single five-petaled flowers, making 'Ruby Glow' a gardener-developed improvement for ornamental appeal.
