Agave havardiana (Havard's Century Plant) An attractive midsized Agave to 2 to 3 feet tall by 3 to 4 feet wide with a tight rosette bearing stout short broad silver-gray to nearly white leaves with dark brown mariginal and terminal spines. It is usually solitary but occasionally older plants can produce offsets. When mature the plant flowers in summer to fall with yellow-green flowers held on a tall branched spike. Plant in full sun with little to no supplemental irrigation required. Hardy to 20 F. We received the seed for this plant from Brian Kemble off of a plant that flowered at the Ruth Bancroft Garden in 2009, a plant we first noticed and admired on a visit to this garden in 2004. At that time it was labeled as being a wide-leafed form of Agave desertii, a plant native to our own Southwestern deserts. While its nativity certainly made this plant more interesting, it was its beautiful broad heavy pale leaves, so different from all other Agave desertii, that attracted our attention. With this plant's susequent maturity and finally its flowerering, it was determined that it was actually a very nice form of the Agave havardiana, a plant from the grasslands in west Texas and northern Mexico, at elevations from 4,000 to 6,000 feet. It was originally described under this name by William Trelease in 1912, who named the plant to honor Valery Havard, who had previously identified it as Agave wizlizeni in the Guadalupe Mountains in 1881 and in the Chisos Mountains in 1883. Havard was a French-born imigrant to the US and was an army officer, physician , author, and botanist. While serving as an army doctor in Texas he was able to explore new territories and discover new plants. It also is called by the common name Chisos Agave as it grows in this mountain range located in the Big Bend National Park as well as in the Davis Mountains just to the north. The pictures on our website were taken of this plant at the Ruth Bancroft Garden.  This description is based on our research and observations made of this plant as it grows in our nursery, in the nursery garden and in other gardens that we have visited. We will also incorporate comments received from others and always appreciate getting feedback of any kind from those who have some additional information about this plant, in particular if this information is contrary to what we have written or if they have additional cultural tips that would aid others in growing Agave havardiana.
