The Shasta daisy (Leucanthemum X superbum) is a perennial plant that is a staple in many flower gardens throughout the world. Shasta daisies were created in 1890 by the American botanist Luther Burbank. The White Knight Shasta daisy variety has single-petal, white flowers and grows between 18 and 24 inches in height. They are easy to grow and hardy in U.S. Department of Agriculture Hardiness Zones 5 to 9.
Prepare the planting area one to two weeks prior to planting. To do this, use a garden hoe to remove all weeds and their roots. Then turn the soil over with a shovel to a depth of between 16 and 18 inches. Plant the White Knight Shasta daisies where they will receive full sun, and ensure that they are provided with well-draining, lime-rich soil.
Spread a 2- to 3-inch layer of organic matter over the planting area. Use grass clippings, leaf mold, compost or aged manure. Mix the organic matter thoroughly into the planting area using a garden fork.
Create planting holes for your White Knight Shasta daisies. Dig each hole twice the diameter of the growing container but approximately the same depth. If you're planting daisies in a bed, or in drifts, space each planting hole 16 to 18 inches apart.
Remove a plant from its container. If it has been growing in a planting cell, push upward from the bottom of the cell with your thumb. If it's been growing in a 1-gallon pot or a smaller container, turn the pot upside down. Hold the plant with your hand against the top of the root ball and gently tap upward along the rim of the growing container with a trowel or a block of wood. Once the pot starts to loosen, slide it off the root ball.
Place a White Knight Shasta daisy into a previously dug planting hole. Use care not to plant the daisy too deep in the hole. Ideally, the top of its root ball should sit at the same level as the surrounding soil.
Scoop in garden soil with a trowel until the planting hole is filled with soil. Pat the soil down around the stem. Then water each plant thoroughly. Spread a 2- to 3-inch layer of mulch around the planting area to help conserve moisture and keep pesky weeds down. Use pine bark, grass clippings or similar organic material.
