About the Coreopsis -
Zagreb :
The Coreopsis ‘Zagreb’, Coreopsis verticillata,
is a prolific bloomer of bright yellow flowers that
bloom from June through October. Winner of the 2001
RHS Award of Garden Merit, Coreopsis ‘Zagreb’ is a
little shorter than the rest of the Coreopsis
family. With a plant height of 15” and a spread of
12-18”, its delicate dark green foliage has an airy
and delicate appearance. ‘Zagreb’ should be planted
in full sun. It is drought-tolerant and tough but
does need well-drained soil.
It should be cut backing early and late summer to
extend the bloom period. Coreopsis Zagreb looks
great with any type of grass, in borders or mass
plantings in sunny gardens. It is very effective in
naturalized areas, rock and cottage gardens or wild
gardens. No garden should be without it.
