Agave 'Trio Sentinel' (Kip's Large Century Plant) - A large stout agave to 7 feet tall by 9 feet wide with a very symmetrical upright rosette of 6 foot long battleship gray colored leaves that are slightly concave on the upper surface, narrow near the base, widest in the middle and tapered toward the tip that terminates with a brown spine and with leaf margins that have regularly spaced medium sized teeth. This plant does not seem to sucker readily and so remains like a big gray solitary sentinel in the garden. Plant with some space in full sun in a decently well drained soil and water occasionally, infrequently or not at all in coastal California gardens. It has proven hardy to repeated temperatures down to 25F and likely can tolerate colder temperatures as evidenced by what appears to be the same plant growing in a Napa Valley garden. This is a great looking large structural plant that is taller and with more slender leaves than the typical century plant, Agave americana, but with thicker leaves and a more uniform and upright habit than the fairly similar Agave 'Sawtooth' (a plant that is sometimes mistakenly sold in California as Agave franzosinii). We received this plant in 2005 from Kip Omweg of Trio Nursery in Carpenteria, California, who did not recall a source but had sold it through his online nursery as Agave atrovirens, but we noted it to be quite different from the large green colored Agave atrovirens that we had in the garden that came from the wilds of Oaxaca. While somewhat similar to Agave atrovirens var. mirabilis, those who have seen this Agave atrovirens variety in the wild do not think it quite matches up with it. Others have also pointed to its similarity to Agave americana var. oaxacensis, but this Agave 'Trio Sentinel' plant seems larger and heavier than Agave americana var. oaxacensis, so it may just remain a mystery for a while yet - other suggestions are certainly welcome! 

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