Salvia azurea is a lovely, easy-to-grow plant here. It blooms in late summer and fall with long wispy stems topped with sky blue flowers. The hummingbirds and butterflies use this plant some, but it's more of a bee plant. It's been very drought tolerant and has survived severe drought and watering bans.

My Climate: USDA Zone 7b, AHS Heat Zone 7/8, Humid

Wild Blue Sage is a rare plant in Illinois with state-listed 'threatened' status, Distribution map on Illinois Prairie Plants site shows its presence in only a few counties; photo submitted was taken in a not highlighted county (Christian Co.)
The preference is full sun and dry, well-drained conditions. Different kinds of soil are acceptable, including those that contain significant amounts of loam, clay, or gravel. A high pH is tolerated. The seed germinates readily, often producing flowering plants during the first year. This is a surprisingly easy plant to grow, with few problems from disease.

Salvia azurea plants are in their third year here, so they are reliably hardy to at least zone 5b. Plants bloomed first year from seed sown early.

Salvia azurea is a perennial native here in Florida, found in the northern and central parts of the state. The species name azurea means "Sky Blue," referring to the lovely flower color. Blue Sage has thin 2"-4" long leaves with toothed margins and appearing opposite on a slender upright, hairy stem. Whorls of three to four bright blue (occasionally white) 1/2"-3/4" flowers are borne in clusters on a 6"-18" elongated spike. Flower form is a long tube with an upper lip and a longer 2-lobed lower lip. The fruit of Salvia azurea is an open cup-shaped, elongated brown pod containing 4 small brown nut-like seeds. Blue Sage is found in habitats of dry woods and pinelands and the flowers are attractive to bees, butterflies, and hummingbirds.

"Salvia azurea (Prairie sage or Blue sage) is a herbaceous perennial in the genus Salvia that is native to Central and Eastern North America.

Its thin, upright stems can grow to 6 feet tall, with narrow, pointed, smooth-edged to serrated, furry to smooth green leaves, connected to their stems by petioles to .4 inches long. There are no basal leaves.

The blue flowers (rarely white), nearly 1/4 to 1/2 inch long, appear summer to autumn near the ends of their branched or unbranched spikes; their calyxes are tubular or bell-shaped and furry. Two varieties are Salvia azurea var. azurea (azure sage) and Salvia azurea var. grandiflora (pitcher sage). It is found on the wild on roadsides, glades, fields and pastures."

8 didn't send up cotyledons (didn't keep track of which were sinkers and floaters at this point); 1 had a stuck seed coat & I waited too long to remove it or I damaged the cotyledons when I did remove it
MrsBinWY On March 17, 2021 Seeds germinated
So, the sinker-floater theory is blown. Lots of seeds in each group have germinated.
MrsBinWY On March 13, 2021 Seeds sown
Experiment: I have pretty poor luck discerning viable seeds from non-viable seeds of this species (visually, air separation, etc.) This time, I put a pinch of seeds in a bowl of water, skimmed off the "floaters" (55) and then strained the "sinkers" (33). I put each group on its own coffee filter, in its own zipper baggie and left at room temp.
