These
are propagations from plants collected near the northernmost location of
this primarily tropical American species, in a rattlesnake-infested prairie
near Goliad. Though they do not grow as large as those seen
farther south, they will become 6' to 8' high and wide mounds of lavender-blue
flowers in October, just in time to provide nectar for the multitude of
Monarch butterflies returning to the high mountains of southern Mexico
for the winter. They are quite adaptable, growing in full sun to
half-day sun and are drought-tolerant once established, as well as being
tolerant of rocky soils.
