Fun Facts
- 🌱 The name 'Saxifraga' comes from Latin words meaning 'stone' (saxum) and 'break' (frangere), referring to the plant's ability to grow in tiny rock crevices and its historical use in folk medicine for breaking up kidney stones.
- 🌱 'Southside Seedling' is a hybrid variety (Saxifraga × urbium) that arose as a spontaneous cross between parent species, discovered in a garden in the UK and propagated for its superior spotted foliage and reliable flowering habit.
- 🌱 The distinctive white spots on the leaves are hydathodes—specialized pores that excrete excess calcium and minerals, a characteristic adaptation of many alpine plants to well-draining, mineral-rich rocky habitats.
