These plants are perennials in zones 9-11 (perhaps perennial even to zone 8) perfectly suited for growing as annuals in colder zones - they self-seed freely for more plants in subsequent years. Oh, and did I mention the hummingbirds love them? These are a perfect addition to any BUTTERFLY garden, too! These plants reach 18" - 24" tall pinch back to make them bush out and you'll get more blooms. Seeds are very small - I suggest starting in pots and setting out to keep them from being washed away by a heavy rain. Pure White blooms atop slender stems that reach 18" - 24". Especially lovely when planted in groups or alongside the blue or red sage/salvia. Can also be grown in containers. Don't let the delicate looking flowers fool you - these are TOUGH plants! Like all Sage (Salvia), they prefer full sun and fairly dry conditions - they definately don't like wet feet, but they will bloom from mid-summer to frost for you growing in dry, poor soil and full boiling sun! Please message me with any problems I am sure we can work it out! Just take a minute, send me a message and I am sure I can make you happy. I am very nice and try my hardest to treat my buyers the way I would like to be treated. Thank You, Syukur
