Audrey, I'm not sure what to call your small agave. Maybe not de-meesteriana because of the total lack of marginal spines and no curvature in the leaves. It could be young and change when it grows up.
We have two native Dudleyas here (ie. growing wild 10 yards from the house). One (D. brittonii) is that rosette succulent which resembles an Echeveria. It can be pale green or powder blue. The other (D. attenuata) has small powder-white "fingers". Their flowers are far less exciting than the average Echeveria (to humans, anyway.... hummingbirds find them just as delectable). But when they're doing well they make up for that in sheer numbers.
