The Ultimate Shasta Daisy Grow Guide
Shasta daisy (Leucanthemum x superbum) is a hybrid flowering perennial named for Mount Shasta in California where it was developed, and for the snowy white petals. The cheerful flowers are characterized by rays of petals surrounding a sunny yellow center. Hardy to USDA zones 5-9, this carefree perennial produces dark green toothed foliage that remains evergreen in milder climates. Shasta daisy bloom time ranges from early summer to early fall.
These improved daisies are more robust, with larger flowers and a longer bloom time than their wild counterparts. There are dozens of varieties, with different plant sizes and single or double flowers. Their height can vary from 6 to 48 inches tall in sizes suitable for small urban lots or spacious properties. The sturdy stems and long vase life make Shasta daisies superb cut flowers.
SHASTA DAISY CARE & PLANTING
How to plant: Grow Shasta daisies on a site that receives at least 6 hours of full sun per day. Follow these steps and plant them 1 to 2 feet apart, depending on the variety.
- Loosen soil in the planting area and amend with compost or other organic matter.
- Dig a hole twice as wide and slightly deeper than the root ball.
- Remove plants from their nursery pots and gently tease out roots if potbound.
- Set the plant in the hole with top of the root ball level with the surrounding soil.
- Backfill the hole with soil, tamp down slightly to remove air pockets and water well.
- Water plants regularly until established.
Soil: Shasta daisy prefers well-amended soil that drains well. Poorly draining soil can lead to root rot. In pots, use a high quality all-purpose potting mix.
Watering: Provide an average amount of water. Soggy soil can lead to root rot. Shasta daisy is moderately drought tolerant once established. Water more frequently during prolonged heat or dry spells.
Fertilizing: In spring, spread a thin layer of compost around the base of plants or apply a continuous-release fertilizer. Alternatively, use a water-soluble fertilizer monthly during the spring and summer.
Overwintering: In colder regions, plants will benefit from winter protection. After cutting plants back in fall, apply several inches of mulch over the crown to insulate plants from extreme cold.
