Growing Notes
Agave Blue Glow shows the unusual character of being generally solitary until it blooms. After blooming the head will die, but be replaced by many pups, which look a bit messy at first, but fill out into a nice cluster over time. Take care when pruning or removing agave, as many have a toxic sap that causes inflammation.
Special Interest
This agave is a hyrbid between A. ocahui and A. attenuata, introduced by Kelly Griffin during his time at Rancho Soledad. Blue glow has a thin (4" across) seven foot tall flower spike that is blue with ruby hints. After blooming it sets keikis (small pups) along the spike that add a whimsical nature to the plant. These can be planted to grow a new agave once the flower spike has finished blooming.
