West Texas grass sage (Salvia reptans) has slender stems to about 3 feet tall, with very narrow green leaves and a bounty of small, cobalt-blue flowers from late summer or early fall well into mid or late fall (generally mid September to mid October for me). Full sun. It is reportedly perennial in Zones 5 to 10. Here at Hayefield (Zones 6/7), it is hardy in a raised bed.
2022-collected seeds are sold out. I hope to collect again in late October to early November 2023. At least 15 seeds.
Please read the germination information as well before ordering.
