Dyckias consist of about 100 species and are characterized by clustering rosettes of tough, succulant leaves, usually viscious spines. Some have green leaves and most have dense coverings of scales that make the foliage gray-green to silvery white. In nature, Dyckias typically grow on rocks in sunny semiarid habitats. Flowers are on tall unbranches spikes, usually orange or yellow. Dyckias like high light and thrive in temperature of 80s°F/low 30s°C or higher during the summer months. Although drought tolerable, these plants love regular watering. Being terrestrial, Dyckias can tolerate heavier potting mixes that most other bromeliads. Use either the same mix as for other bromeliads, or a cactus/succulent potting mix.
