Parodia roseolutea (Vliet) Hofacker, A.S.Oliveira & R.Pontes
Notocactus herteri f. roseoluteus, Notocactus herteri subsp. roseoluteus, Notocactus roseoluteus
Parodia roseolutea, formerly known as Notocactus roseoluteus, is a small cactus with a spherical, green to grayish-green stem with 15 to 18 strongly tuberculate ribs lined with clusters of needle-like spines. As it slowly grows, the solitary stem becomes short-cylindrical and can reach a height of 8 inches (20 cm) and a diameter of 7.2 inches (18 cm). The woolly areoles are positioned between the tubercles, each bearing eight radial and four central spines. The radial spines are whitish with a maroon tip and up to 0.5 inches (1.2 cm) long, while the central spines are usually darker and up to 1 inch (2.5 cm) long.
During the spring, the stem produces abundant, shiny salmon flowers with a yellow center. They are up to 3.2 inches (8 cm) in diameter with a short tube covered with white wool and brown bristles and appear at the top of the stem.
The specific epithet "roseolutea (roh-see-oh-LOO-tee-uh)" means "pink-yellow, rosy-yellow" and refers to the bi-colored flowers.
How to Grow and Care for Parodia roseolutea
Light: Parodia roseolutea likes slightly less sun than other cacti and prefers partial shade during the hottest part of the day. It can handle direct sunlight in the morning and afternoon. If growing this cactus indoors on a sunny windowsill, rotate it every two weeks to encourage balanced growth. Move the cactus outdoors from spring to fall if possible.
Soil: For a healthy plant, soil with good drainage is crucial. Use commercial soil for cacti, or make your own well-draining mix.
Hardiness: This cactus thrives in warm, desert-like conditions and will not survive a hard frost. If there is a risk of freezing temperatures, it is best to plant it in a container that can be brought indoors. Parodia roseolutea can withstand temperatures as low as 25 (-3.9 °C). USDA Plant Hardiness Zones 9b to 11b, 25 to 50 °F (-3.9 to 10 °C).
Watering: Water deeply during its growing season, but allow the soil to dry out before watering again. During winter, when this cactus is dormant, provide water only enough to keep the soil from becoming bone dry.
Fertilizing: While not necessary, Parodia roseolutea will respond well to a low-balanced soluble fertilizer diluted to half the recommended strength. However, suspend feeding in winter.
Repotting: If growing in a container, repot as needed in spring or early summer. Ensure the soil is dry before repotting, and always place the plant in a container with drainage holes.
Propagation: Since it rarely produces offsets, this cactus is propagated by seed. For best results, sow the seeds in spring.
