Various cultivars of the Blue Weber Agave have been developed for ornamental purposes. These include the 'Mediopicta' variety, which has creamy-white stripes, and the 'Issetniegel' cultivar, known for its compact size and variegated foliage.

The 'Centuri' cultivar is particularly interesting due to its shorter growth habit, making it suitable for smaller gardens or container planting.

Blue Weber Agaves are relatively low-maintenance plants, requiring well-draining soil and full sun. They are drought-tolerant, needing water only once a week or even less in established plants.

Propagating Blue Weber Agaves is typically done through offsets (pups) or seed, but it's essential to be patient, as these processes can be slow. Applying a balanced, organic fertilizer in spring can help encourage growth.

The Blue Weber Agave reaches its floral peak after it has ceased vegetative growth, sending up a towering, extraordinary flower stalk. This impressive inflorescence can reach heights of 15 to 25 feet, making it a spectacular sight.

After flowering, the parent plant typically dies, but not before producing numerous pups around its base, ensuring the plant's survival and replication.
