Cleome houtteana Adding vertical interest and delicate airiness to the cottage garden, 'Rose Queen' is an old fashioned heirloom favorite. A fast-growing annual plant with a dramatically large, deep pastel pink flower bloom atop sturdy 4 foot stalks. A very stately centerpiece in the garden or as a cut flower. If pinched when ~6 inches tall, will branch out to produce a half dozen or more blooms. Best started in cool soil, does fine in partial shade and is an attractive pollinator plant.
Growing Notes Sow seeds thinly and cover with ¼ inch of soil. Firm soil lightly and keep evenly moist. Seedlings will emerge in 14-21 days. Thin or relocate to 2 feet part when established. Full sun. Moderate water. Can also be fall planted, when it is too cold to germinate seeds and soil temperatures are below 45 degrees F; the seed will lay dormant through the winter.
