Plant in full sun to part shade and water regularly to occasionally (the more water and fertilizer this plant gets the faster it will grow). Outdoor hardiness is unknown although we had it outdoors during winters where the low temperature reached 28° F and we feel that it likely will tolerate at least short duration temperatures down to around 25° F.

Agave desmetiana is the likely parent species of this plant and so we list is as a cultivar of this species. For more information about this species and its current nomenclature see our listing for Agave desmetiana. We have not been able to verify the origin of this cultivar but it seems to have first come into the succulent trade in Australia around 2016 and this might explain the spelling of the cultivar name as "traveller" is the spelling used more commonly in Commonwealth countries, while it is generally spelled with one "l" as "Traveler" in the US - for this reason we have also seen it listed as 'Galactic Traveler' in the U.S. We received our first stock plants in 2021 from Tony and Holly at Krock Plants in Santa Barbara. The first plant of this cultivar we released was for the Ganna Walska Lotusland Exceptional Plant Auction in 2023. As with the similar Agave 'Joe Hoak', which there is some speculation 'Galactic Traveller' is a sport of, it is one of the showiest of the Agave we grow! 

The information about Agave desmetiana 'Galactic Traveller' displayed on this web page is based on our research conducted in the nursery's horticultural library and from reliable online resources. We also include observations made about it as it grows in our nursery gardens and other gardens we have visited, as well how the crops have performed in containers in our nursery field. We will also incorporate comments we receive from others and welcome hearing from anyone with additional information, particularly if they can share cultural information that would aid others in growing this plant.
