Description
What is that smell? Ripe passionfruit...mint...a hint of
camphor. Brush by the foliage of mountain marigold and you are hit
with a distinctive, pungent fragrance that some people just don't
like. Mountain marigold, or Copper Canyon daisy, is a sprawling,
shrubby perennial daisy with delicately filigreed highly aromatic
foliage. The lacy compound leaves are 2-6 in (5-15 cm)long, with
serrated leaflets. The flower heads are almost 2 in (5 cm) across,
with bright yellow-gold rays and darker yellow discs. Mountain
marigold forms a sprawling mound up to 4 ft (1.2 m) high and 6 ft
(2 m) across.
Location
Mountain marigold occurs naturally in mountain canyons between
4000 ft (1200 m) and 8000 ft (2400 m) above sea level in northern
Mexico and southern Arizona. It was discovered in the late 1800's
in southeastern Arizona, by the Lemmons, husband and wife plant
collectors. The famous Harvard University botanist, Asa Gray, named
the plant after the couple.
Culture
Plant mountain marigold in a place where it can be free to
sprawl all summer, since frequent pruning is said to inhibit
flowering. Unlike annual marigolds, mountain marigold is not
susceptible to spider mites.
Light: Mountain marigold does best in full sun, but can take a
light, high shade. It gets leggy and may not bloom in full
shade.
Moisture: Mountain marigold must be grown in well drained
soil. It is very tolerant of drought conditions. Just be sure to
keep a new plant well watered until it is established. This is a
plant that will thrive on thin, chalky soils. Give the plant plenty
of water and fertilizer and it will sprawl excessively producing
elongated, droopy stems.
Hardiness: USDA Zones 8-11. Moutain marigold is often said to
have a USDA hardiness range of 9b-11, but like so many other Zone 9
and 10 perennials, it usually comes back in spring after freezing
to the ground in winter. It has returned here in my North Florida
garden after a winter low of 17°F (-8°C). In frost-free locations,
it blooms all winter and into spring.
Propagation: Cuttings are very easy to root. You also can
divide clumps in spring or plant from seed.
Usage
Mountain marigold is very tolerant of heat, drought and poor,
calcareous soils, so plant it where other, more finicky flowers
might not be happy. Mountain marigold blooms only during short-day
seasons, so be patient as the shrub grows throughout the summer; it
will reward you with a brilliant display of yellow flowers in the
fall and winter (until the first frost). White-tailed deer don't
eat mountain marigold, but the bees and butterflies love the
flower's nectar.
I like to plant mountain marigold along paths in the
landscape, and at the edges of perennial beds so I get the smell
every time I brush by. Some people can't stand the smell,
though.
Features
Tagetes palmeri is a very closely related marigold from Sonora
that is a little larger and more robust, and not quite as cold
tolerant as T. lemmonii. It has been suggested that some of the
mountain marigolds found in the nursery trade are actually this
species. Mexican tarragon Tagetes lucida is another fall blooming
shrubby marigold with aromatic foliage.
