Fragrant White Flowers for Sunny Borders

Rocket Empress candytuft (Iberis amara) is a fast-growing annual with abundant white flower clusters on upright stems. Plant it in beds, borders, or sunny slopes for a fresh, bright display, or grow a patch for fragrant cut flowers to bring indoors.

How to Sow

Direct sow after the last spring frost for early-summer color, or sow in fall where local conditions permit overwintering for spring bloom. Repeat sowings every few weeks for a longer flowering display.

1. Prepare a well-drained seedbed and sow just below the soil surface.
2. Keep the soil evenly moist, not waterlogged, at approximately 65–70°F.
3. Allow approximately 15–20 days for germination.
4. Direct sowing is preferred because seedlings do not transplant well. If starting indoors, use individual biodegradable pots to minimize root disturbance.

Growing and Care

Water regularly without leaving the soil soggy. Established plants can tolerate short dry periods, but good drainage remains essential. Plants may decline during intense summer heat.

Remove spent flowers to prolong blooming. After flowering finishes, trim foliage back by about one-third unless you are saving seed. Plants may self-sow when seedheads are allowed to mature.

Cut Flowers and Seed Saving

For fresh arrangements, cut long stems when flowers have just opened. Strip leaves that would sit below the waterline and place stems in water immediately.

To save seed, allow seedheads to turn papery and tan. Shake ripe heads over a container to collect the flattened brown seeds, then clean and store them in a cool, dry place.

Available Seed Packs

Choose 50 seeds, 1/4 oz, 1 oz, or 1/4 lb. The listed approximate count is 11,313 seeds per ounce; counts in weight-based packs may vary.
