Leucanthemum
x.superbum:
(Common Name:
Shasta Daisy).
Introduced from the USA at
the turn the 20th Century these familiar white (or pale yellow) daisies
come in a range of heights, as single or fully double flowers, and with
simple petals or frilly, feather-like structures. All can be relied on to
flower in flushes from June through September - most will re-bloom happily
if cut back after each flush. Propagate by division in spring. There are
no major problems to avoid - slugs can be nuisance on small plants,
blackfly may appear in mid summer and if black spots appear on the leaves
either ignore or use a systemic fungicide.
The varieties we sell grow
to 60-90cm in height. All prefer a sunny spot and some moisture in summer.
Feed well in spring.

these plants can be found in the RHS Journal "The Garden" Vol
