3723 King Cup Cacti ( Echinocereus triglochidiatus )
One of the most attractive hedgehog cacti is the King Cup, which grows in clumps as much as 3-4 feet across but usually smaller. The bright red-orange flowers often cover the whole plant, which is cylindrical and low-growing, often hugging up against some larger plant.
The numerous flowers grow at the top of the stems, all about the same height, giving a full view of all the flowers at one glance. They last for several days. The flowers vary slightly in color as a result of soil type or genetic differences.
Zones 7-10. Hardy to 20°F and lower. Full sun to light shade in hotter desert gardens. Needs little water and good drainage.
