Sweet Annie makes the most fabulously fragrant flower crowns easy to make! She's also an exquisite filler in both fresh and dry arrangements. Her deep green, fern-like foliage quickly grows 4 to 6 feet tall, even in poor soil and partial sun. She is sweetly fragrant, like so many of her cousins in the sage family, remaining so for years in dry arrangements and wreaths. Sow sweet annie about four weeks before final frost, transplanting out after final frost with one foot between plants.
