Pampas Grass Cortaderia selloana
Introduction
Pampas Grass forms large, impressive clumps,
8 to 10 feet
high and wide, with beautiful silver to white
feathery plumes
arising on female plants in summer and autumn.
This
vigorous ornamental grass is widely used as a
lawn specimen
but its quick growth rate and large size make
it unsuitable for
most home landscapes. However, it is ideal for
barrier or
windbreak plantings and has a place in larger
areas such as
along highways or in commercial or industrial
landscapes.

Use and Management
In sun or partial shade, Pampas Grass grows well
in most
soils except very wet ones, tolerating drought
and salt spray,
making it especially attractive for seaside landscapes.
Be
careful in the placement of Pampas Grass in the
landscape,
however, as it gets larger than most people realize.
Many are
planted in residential landscapes and later removed
because it
has grown too large. Children may cut themselves
if they
accidentally fall into the plant because the
edges of the leaves
are sharply serrated. Plant six to eight feet
apart in a mass
planting.
Cultivars include: ‘Argenteum’, silvery plumes;
‘Gold
Band’, yellow-edged leaves; ‘Pumila’, dwarf,
four to six feet
high; ‘Rendatleri’, pink plumes; ‘Rosa Feder’,
pink plumes;
‘Sunningdale Silver’, silvery white plumes; and
‘White’, white,
feathery plumes.
Propagation is by division.
