A human habitat is a haven you create in your landscape where you can
relax, recharge your emotional batteries and feel as one with nature.
In the previous column, I pointed out that habitats aren’t just for
wildlife. They can be your own special outdoor refuge from all of
life’s stress factors, regardless of the acreage.
As we discussed last time, aim to please as many of the five senses as
possible. Sight and smell, certainly, but don’t forget the sensations
of sound, touch and even taste. Create a sanctuary for the senses, sit
back and relax! If you missed the previous column, titled “Your garden
can be a human habitat,” you can find it at my Web site www.landsteward.org
In that column, I suggested some evergreens, ornamental shrubs and
hardscaping. As promised, this time I’ll discuss some ornamental
grasses that will add the perfect peaceful ambience to your haven.
Ornamental grasses can be divided into two categories: cool season and
warm season grasses. Cool season grasses start growing quite early in
the spring when temperatures are still cool. They can even remain semi-
evergreen over the winter, except in extreme conditions. At the height
of a hot summer, they need watering or they are likely to turn brown
and go dormant.
Warm season grasses wait for warmer weather before beginning their
growth pattern and still look good when temperatures are high and
moisture is limited.
You can also differentiate grasses by their growth habits. Clump-
forming grasses grow in neat clumps or mounds and are often selected
to enhance other perennials that they surround. Rhizome-forming
grasses have a root system that spreads out beneath the soil. This can
be an advantage if you want an ornamental grass that will spread
quickly but be aware that this tends to make them invasive and they
can overwhelm other plants.
Cheryl and I believe that ornamental grasses add so much to a human
habitat. Beautiful in their own right as they sway languidly in the
slightest breeze, they communicate a feeling of peace and wellbeing.
But additionally they can enhance other plants that they surround, the
way that supporting actors can bring out the best in the stars of a
Elijah Blue (Festuca ovina glauca)
Elijah Blue is a cool season ornamental grass that is the bluest of
all the blue fescues. In the spring, Elijah’s blue coloring makes a
great backdrop for dianthus (pinks) as their colors look wonderful
together. Elijah Blue forms neat, rounded clumps, about 12 inches
high, with color that lasts almost year round.
Calamagrostis x acutiflora ‘Karl Foerster’
Another superb clumping cool season ornamental grass, ‘Karl Foerster’
is a low maintenance, easy care grass that forms deep green, shiny
foliage in early spring and loose, feathery flower iridescences in
June that mature from pale pink to golden tan. The foliage clumps rise
to about 2 or 3 feet with flower stems about 5 feet tall. It is
sometimes described as ‘perpetual motion grass’ as the slightest
breeze sets it in motion. It is also delightful in patio pot
Grass Acorus Minimus
Technically, this warm season dwarf ornamental is an acorus rather
than a grass, according to horticulturists, but it sure looks and acts
like a grass! Cheryl and I think this is one of the cutest of the
Sweet Flag varieties and we love the aroma of its sweetly fragrant
foliage on spring mornings. Note that this is a rhizome-forming plant
and will spread slowly to form a mat of tiny evergreen foliage. Ideal
between stepping stones in your human habitat.
Grass Pink Muhly
This warm season clumping grass comes into its own as summer fades
into fall and its giant puffs of cotton candy pink plumes begin their
autumn dance of color. Reaching 3 to 4 feet high, this low maintenance
grass can extend your outdoor enjoyment well into fall.
