Product Description
Iberis umbellata. Umbels of fragrant flowers unfold from a central point in pink to off-white on annual plants that grow 20-30cm (8-10″) tall with a spreading habit. Iberis prefers well drained soil in full sun, and has a remarkable characteristic of blooming just weeks after sowing. Direct sow Candytuft Iberis seeds from last frost date to mid-July for continuous blooms. Iberis may self sow in the right conditions, but will not become invasive. Try planting some Iberis seeds for use in xeriscaping, as the plants are quite drought tolerant. This plant looks good in containers, and is highly attractive to beneficial insects over a long flowering period.

How to Grow Iberis
Iberis umbellata is an annual plant originating in Spain. It is a distant relative of the cabbage.
Latin
Iberis umbellata
Family: Brassicaceae
Difficulty
Easy
Season & Zone
Exposure: Full sun – some afternoon shade is appreciated
Zone: 1-10
Timing
Start indoors 6-8 weeks before last frost date, around early to mid-February on the coast. Or direct sow outdoors from your last date, every two weeks into July for a continuous bloom period. Seeds should germinate in 10-20 days. Ideal soil temperature for germination: 21-30°C (70-85°F).
Starting
If starting indoors, use peat or coir pots and bottom heat. Only cover seed by a couple of millimeters (1/8″) of soil. Transplant out after last frost at 15-30cm (6-12″) apart.
Growing
Iberis does not respond well to transplanting or being moved. Direct sowing may be simplest. Choose any well-drained garden soil with a neutral pH range of 6.0-7.0. Trim plants lightly after flowering to encourage a second bloom. Iberis may self sow.

One of my absolute favourites. A few years ago I scattered the seeds between my perennials. What a beautiful carpet of colour! They bloom for weeks and then I shear them back for a second bloom. They self sow without taking over, they always seem to find their way into the spaces they are needed.

Given the fact that I direct sowed them in a spot that gets constant squirrel attacks, I cannot vouch for the germination rate, but what germinates is pretty and fragrant. They are good looking and trouble free. I gave them a part shade spot, mostly clay soil and they seem to have adapted. They must look amazing in big clumps.
