Leucanthemum superbum Goldfinch - Shasta Daisy

Leucanthemum x superbum 'Goldfinch' is a relatively recent variety of large daisy considered currently to be one, if not the best yellow-flowered daisy. Its large semi-double heads with feathery frills display a true yellow colour that lasts a long time before turning to ivory.  In the height of summer, the plant forms a beautiful cluster of flowers ranging from yellow to almost white. It is also the earliest flowering variety and its flowers continue to bloom for several weeks if faded flowers are regularly removed. This variety is also a fully hardy perennial and easy to grow in full sun, in ordinary but not too dry soil. Its flowers hold up well in vases and in borders.

The genus Leucanthemum belongs to the family Asteraceae. 'Goldfinch' undoubtedly gets its name from the intense yellow colour and feathery appearance of the flowers. Introduced in 2014, this horticultural hybrid is the result of cross-breeding with Leucanthemum x superbum, the large daisy that we know well. The plant forms a dense and low-growing clump, consisting of often persistent basal rosettes caught in a tangle of short, horizontal and more or less underground stems.  Robust, leafy stems rise in summer, taller than wide, reaching about 60 cm (24in) in height. The root system spreads rapidly, occupying at least 50 cm (20in) of soil. Luxuriant in summer, it disappears completely in winter. Flowering, which starts at the end of June and reaches its peak in July, can continue until September if faded flowers are regularly removed. It takes the form of large solitary heads, 10 cm (4in) in diameter, with yellow outer ligules, whose shade gradually varies, creating a very pretty gradient from lemon yellow to ivory white, enhanced by a large, clearly defined, bright yellow centre. The flower stems are very sturdy and ideal for cutting. The leaves are dark green, simple and alternate, 5 to 8 cm (2 to 3in) long, with a regularly toothed margin. The plant, which is very long-lived, reaches full maturity in five years.

In daisies, one does not find extravagant colours, but it is the structure of the flowers that stands out. Accompany these flowers with that of cosmos, combine them with peonies, columbines, asters, blue lupins, campanulas or snapdragons, for example. Be creative with this flower, in the garden or in a vase in the house, to produce a delightful and unique display.  'Goldfinch' will bring a touch of brightness, but also a breath of whimsy, to a rustic scene that will evoke gardens of the past.
