The Haworthia limifolia Spider White is produced on a larger scale since 2014. The mutant was found in the collection of a South African succulent-collector.
The Dutch company Handelskwekerij Lock is the only nursery that has the right to produce this succulent in Europe. The Spider White won the 'Glass Tulip' in 2015, a Dutch award, for being the best new houseplant.
It takes a full year for the Spider White to grow. Tissue culture is needed.
