|phenology=Flowering spring–early summer; fruiting summer.

|discussion=<p>Amsonia peeblesii generally resembles narrower-leaved, glabrous forms of A. palmeri. The stems of A. peeblesii are much more often branched below the midpoint, and the flowers are usually larger; the distribution of A. peeblesii is narrower and more northerly, whereas A. palmeri is largely found in southern and western portions of Arizona.</p>
