Description
Leucanthemum 'Diamond Supreme' gleams in the garden like a classic jewel, its white petals circling bold yellow hearts in a timeless summer combination. This Shasta daisy stands out with neatly toothed green leaves, upright stems, and blooms that keep coming from midsummer right through the season if deadheaded. The fresh, crisp flowers of Leucanthemum 'Diamond Supreme' lift the mood instantly, whether it’s planted in borders, edging paths, or dotted through pots on the patio. Few plants manage to look this effortlessly cheerful, and even fewer keep the performance going so reliably.
One of the joys of Leucanthemum 'Diamond Supreme' is its versatility. The tall, sturdy stems are ideal for cutting, making this variety as good for the vase as it is for the garden. Plant Leucanthemum 'Diamond Supreme' in bold groups for meadow-like sweeps of white and gold, or combine it with pastel salvias, pink roses, or airy grasses for a softer effect. Wherever it’s placed, Leucanthemum 'Diamond Supreme' proves that simplicity can outshine complexity, its clean daisy shape glowing like sunshine on a stem. When it comes to Shasta daisies, this variety really does set a new standard of summer brilliance.

Useful information
-
Soak the Leucanthemum 'Diamond Supreme' roots in water for 3-6 hours prior to planting
Plant your "Shasta daisy" bare roots into temporary pots with a multipurpose compost within a week of delivery and grow-on in a sheltered spot outdoors
Choose a pot which comfortably fits the bare roots. Some have a noticeable crown which should be just below the soil surface with any top growth exposed. Some varieties are a length of root which should be planted lengthways and shallowly (1-2cm deep).
Plant out into borders or permanent containers in late spring or early summer once in full growth. Choose a position in sun or shade depending on the variety.
