Matucana aurantiaca subsp. fruticosa (F.Ritter) Mottram
Matucana fruticosa, Borzicactus fruticosus
Matucana aurantiaca subsp. fruticosa is a cactus that grows in clusters of ribbed, spiny, cylindrical stems. The stems are up to 20 inches (50 cm) tall and 2.4 inches (6 cm) in diameter. Spines are needle-like, yellow to brown, and up to 2.4 inches (6 cm) long. Flowers are funnel-shaped, golden yellow and crimson, up to 3.6 inches (9 cm) long, up to 2 inches (5 cm) in diameter, and appear in summer.
USDA hardiness zones 10b to 11b: from 35 °F (+1.7 °C) to 50 °F (+10 °C).
How to Grow and Care
All species are sensitive to moisture. Therefore, watering should be limited to the growing season and should be made only when the substrate is completely dry. It must be suspended during the winter. Since these plants tend to lose their roots in cold and wet, they must be kept warm even in winter. A temperature not under 50 °F (10 °C) is suitable. Some species, for natural adaptation, can resist at temperatures below 32°F (0°C).
If the plants are in the vegetative stage and optimal environmental conditions (a low moisture content with substantial temperature swing between day and night is appreciated), the growth is quite fast. You can get blooms already after 2 to 3 years after birth.
Matucana must be grown in very porous and draining soil. It can be composed largely of sand, lapilli, and gravel. To encourage the development of a dense network of spines, the quality of the nutrients in the substrate is very important. The soil must be rich in potassium, poor in nitrogen. Since the roots are very delicate and subject to rot, the soil should be kept as dry as possible. Do not forget that in their natural environment, these plants grow in steep and inaccessible places.
