Why are artisan Haworthia valuable? There are faster growing inexpensive Haworthia commonly available in many plant stores. These are uniformly green plants and rapidly form pups. But the more beautiful Haworthia varieties and hybrids require nurturing - they are slower growing plants that tend to remain as solitary rosettes and cannot be propagated from pups. It usually takes these plants about 4 years to reach flowering size from seed, and with some varieties they can take up to 5 years to start showing their adult aesthetic traits. For this reason, they are more expensive than the more common green varieties. Standout seedlings are rarer, in high demand worldwide and thus may be very high-priced.
