Protea
Protea spp. (P. cynaroides, P. nerifolia, P. repens)
📖 About this plant
Among the most ancient and spectacular flowers on Earth, proteas produce enormous, artichoke-like flower heads in pink, red, white, and yellow that can measure 15-30 cm across. The King Protea (P. cynaroides) bears South Africa’s national flower. Their tough, leathery leaves and remarkable drought tolerance reflect millions of years of adaptation to harsh conditions. Each flower head is actually a composite of hundreds of tiny individual florets.
🧑🌾 Care requirements
Full sun (6-8 hrs)
Every 1-2 weeks
Low (30-50%)
10-28°C
Extremely well-draining, nutrient-poor, acidic soil (pH 5.0-6.5) with sand, gravel, and minimal organic matter; avoid phosphorus-heavy soils or fertilizers
Very light feeding with low-phosphorus fertilizer; proteas are adapted to poor soils and are easily damaged by excess nutrients
