These tall, branching, deciduous, extraordinary
member of the poppy family, has gray-green foliage up to 5 inches long
with 3-5 lobes and a waxy texture. One of the tallest members of the
poppy family, this species also boasts the largest blooms in the genus
which closely resemble fried eggs. In summer, many four-inch, delicate,
crepe-like blooms are formed at the tops of tall stems each bearing six
white crinkled petals and fluffy centers comprised of many yellow
stamens. Blooms have a faint citrus scent most noticeable when in
full bloom. Mature height is 3-8 feet with an indefinite spread.
Perennial in zones 7-11. Performs best in full sun with a light, sandy
soil that is fertile but well-drained. Spread can be difficult to
control in ideal soil as plants spread by underground rhizomes
Romneya’s natural habitat is quite diverse and plants will adapt to a
wide range of conditions. Plants resent transplanting and therefore
careful consideration should be given when choosing a permanent
location. Plants require weekly watering while getting established, but
are highly drought tolerant after their second year of growth. Cut
back hard in fall to encourage uniformity and keep plants tidy. Blooms
are attractive to honey bees and other pollinators. Idea for use as a
specimen planting, low privacy screening or for the back of mixed beds
and borders.
Smoke treatments are beneficial in promoting germination. -In their natural habitat these seeds only germinate after bush fires due to heat
and the toxins in the smoke attacking and helping to break down the
protective seed coat. A good seed supplier will provide smoke primer or you can smoke the seeds yourself.
