Parodia haselbergii
Previously called Brasilicactus haselbergii this is a favourite amongst collectors due to its long lasting bright red flowers in late winter. Matures at 10cm, fast growing but easily killed with overwatering.
Position - under fully covered positions outdoors.
Indoors only in sunny positions otherwise plant will rot. Flowering will only occur in good light.
Watering - can be watered in the warmer months and rarely in winter. Plants will survive without water for very long periods.
Feeding - 25% of recommended dosage monthly in growing period. The less fertiliser, the better the shape of the plant. Fertilisers high in nitrogen can produce larger plants with less colour.
Repotting - can be left to overgrow their pots or repotted in the warmer months in almost any well drained potting mix.

Description: Parodia haselbergiiSN|1795]]SN|1795]] subsp. graessneri (a.k.a. Brasilicactus haselbergiiSN|1798]]SN|1798]], Notocactus haselbergiiSN|1797]]SN|1797]]) is a medium- sized solitary, fast growing cactus closely resembling Parodia haselbergiiSN|1795]]SN|1795]], but has as many as 60 radial spines. The spines are pale to golden yellow, occasionally brownish or nearly all white, to 2 cm or more. The flowers are small yellowish green to almost truly green, while those of Parodia haselbergiiSN|1795]]SN|1795]] are orange-red to bright red. These cacti are self-fertile, do not offset, and have a very short floral tube. They are among the earliest Notocacti to bloom in the spring. As with P. graessneri, the growing centre tends to be on one side of the stem.
Stem: Spherical flattened or spherical and depressed at the top, deep green, almost completely hidden by dense spines, up to 10 cm tall, 15 cm in diameter. The crown of the plant is usually set at an angle to prevent water-sitting.
Ribs: More than 30 (up to 60), low arranged in spirals.
