Distinguishing Traits

Native to Australian coastal cliffs. Snowy white mounding shrub grown for unique foliage—resembles underwater coral or leafless weed. Appears prickly but is fuzzy to touch (small narrow leaves compressed against architectural stems). Evergreen, 1–3 ft tall/wide. Late spring/summer: small button-shaped green flower clusters. Winter: foliage becomes more pronounced, almost green-white.

How to Use It

White in the garden delights year-round, especially when days shorten and garden time is spent in darkness. Fluorescent coloring reflects light on path edges. Salt affinity suits saltwater pools and coastal banks. Great in coastal gardens, planters, alongside succulents.

Planting Notes

Thrives in seaside conditions; growth improves in direct salty wind. Sensitive to humidity and temperature swings. Plant in direct sun, sandy, quick-draining soil. Very drought tolerant; don't overwater; watch for fungus. Hardy to 20°F, somewhat frost tolerant. Mulch roots over winter. As shrub matures, cut dead/woody parts and trim spent flowers. Doesn't react well to hard pruning; pinch young stems for fuller growth.
