Weingartia neumanniana, is the smaller and slower growing Weingartia, sometimes considered as a difficult to grow plant. The plant has somewhat grayish stem and flowers that are larger than with more common Weingartias, but not that abundant.
This species has thick fleshy roots, the source of problems when not grown in mineral substrate. The common cactus care suits it well, with may be slightly restricted water supply in the summer. Large clumps of this species are rarely seen in culture and always draw a stare.
