Parodia Haselbergii - Scarlet Ball Cactus

Scarlet Ball Cactus

Parodia haselbergii  

Parodia and Notocactus have been merged into a single genus, native to upland Argentina, Peru, Bolivia, Brazil, Colombia and Uruguay. 

Parodia haselbergii is one of the first cactii plants to flower each year. Started flowering in April in the UK in my greenhouse (not heated)
