Parodia buiningii - seeds

Parodia buiningii (Buxbaum) is a solitary, flattened cactus only a few cm in height with long, straw-yellow spines. It bears large and showy yellow flowers, and produces hairy fruit and black seeds.
This is an easy plant to cultivate. It likes to be kept cool, and needs only a short rest in winter. It can can tolerate light frost. Grow in full sun or light shade, but it doesn't like full, hot blazing sun in the central summer months. Water occasionally in winter so the roots do not dry out completely, and water regularly in summer. Some growers suggest to use exclusively rain water. But be careful, as it will rot easily if the substrate is wet and cold. It tends to lose its roots in winter. The root system of this plant is comparatively small, and it is best to grow it in a shallow pot using a neutral to slightly acidic compost, with plenty of extra grit. Give an occasional tonic of sequestrated iron.
All seeds are fresh of this season and obtained from my personal collection.
NOTE: cactus seeds could be sown in any season under control environment, however if you wanna go with nature then best time to sow the seeds is early spring/summer )
