Description
Matucana haynei, also known as Matucana haynii, is a small cactus with a green, spherical, usually solitary stem with tuberculate ribs and densely covered with numerous spines. The stem can grow up to 12 inches (30 cm) in diameter. Each areole bears 1 to 20 central spines measuring up to 2.8 inches (7 cm) long and 14 to 45 radial spines measuring up to 1.6 inches (4 cm) long. They vary in color, ranging from white and pale brown to grey.
The flowers are tubular, scarlet red, and appear in spring. They can reach up to 3.6 inches (9 cm) long and 1.6 inches (4 cm) in diameter. The fruits are small, spherical to club-shaped, and reddish-green.
Hardiness
USDA hardiness zones 9b to 11b: from 25 °F (−3.9 °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 made only when the substrate is completely dry. It must be suspended during the winter. Since they tend to lose their roots in cold and wet, these plants must be kept warm even in winter. A temperature not under 50 °F (10 °C) is suitable. Some species, for natural adaptation, can resist temperatures below 32°F (0°C).
The growth is fast 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). You can get blooms already after 2 to 3 years after birth.
Matucana must be grown in very porous and draining soil, which can be composed largely of sand, lapilli, and gravel. The quality of the nutrients in the substrate is very important to encourage the development of a dense network of the spine. The soil must be rich in potassium and 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 these plants grow in steep and inaccessible places in their natural environment.
