The Story
Plant Bio
Curio talinoides is an evergreen succulent shrub native to South Africa, forming dense mats of brittle, fleshy stems that root where they touch the ground. Its linear, sickle-shaped leaves are covered in a powdery white waxy bloom, giving them a striking bluish-grey to silvery color.
The plant's inconspicuous dull-white to pale yellow flowers appear in late spring to early summer, but its primary appeal is its architectural foliage. It thrives in full sun and well-draining soil, maintaining its intense blue coloration and compact form under lean, gritty conditions.

Planting
How to Grow
- Choose a site with full sun to partial shade and well-draining soil.
- Ensure soil is gritty or sandy to prevent waterlogging and root rot.
- Plant with the crown at soil level, allowing space for spreading.
- Water thoroughly after planting, then allow soil to dry completely between waterings.
Pro Tip
Plant in lean, gritty soil and provide full sun for the most compact growth and vibrant blue foliage; overwatering or rich soil quickly leads to root rot and leggy stems.
