Iberis can tolerate some shade and the soil should be slightly alkaline. Deadheading regularly is required in order to prolong blooming.1
Try to plant in a location that enjoys full sun and remember to water moderately. Keep in mind when planting that Iberis sempervirens is thought of as half hardy, so remember to watch your frost dates and ensure you have this plant protected when the temperature dips. Iberis sempervirens requires a loamy soil with a ph of 6.6 - 8.5 - it grows best in weakly acidic soil to weakly alkaline soil.Candytuft
