Big Bluestem "Vitman" |
Even the smallest gardens can use a
little vertical amazement. Vertical in
the form of ornamental grass.
Perennial ornamental grass in Zone 5
(where we live in Illinois) hasn’t had too many new varieties because many
can’t take our freezing ground temperatures. Most of the hardy ones are native to this
area.
I have several varieties and I love how
they look and perform:
Small clumps:
Blue Festuca “Elijah Blue” – 9x10 inches
in a soft blue clump.
Japanese Blood Grass “Red Baron” – 18
inches green with deep red stripes and tips.
Tiger Grass – 18 inches – likes to
spread.

Medium clumps:
Little Bluestem “Blaze” – 3 ft. and turns
red in the fall.
Little Bluestem “The Blues” – 3 ft. with
blue leaves.
Flame Grass “Purpurascens” – 3 ft. with
red/orange fall color.
Maiden Grass “Huron Sunrise” – 4 ft. with
red seed heads in fall.
Large clumps:
Big Bluestem “Vitman” – 8 ft or more with
large seed heads in the fall.
Zebra Grass “Strietus” – 8 ft. – stripes
Japanese Blood Grass "Red Baron" |
Crazy Invasive:
Blue Dune Grass – 3 ft. light blue straps
– underground runners. Beautiful and
impossible to keep in bounds. I don’t
recommend planting.
Bamboo – Technically not a grass but some
people use as grass. Do not plant or you
will regret it to the point of it growing into your house, into your bedroom
and overtaking the mattress and eventually covering your spouse who you won’t
be able to find and people will suspect foul play. I’m telling you this because I care.

May or may not survive
the winter:
Japanese
forest grass “Aureola” – 2 ft. – lime and green strip leaves
Northern Sea Oats – 3 ft. – some consider
invasive.
Corkscrew Rush “Spiralis” – 2 ft. Green leaves that twist.
Giant Reed Grass – 12 ft. – looks like a
corn stalk. Can be invasive under
perfect conditions.
The choices are expanding as annual
ornamental grass has been embraced for potting. The sizes, colors, patterns and fall seed
heads are just some of the fun attributes.
There are tiny examples for fairy gardens and tall upright for limited
space. Since some are up to 3 ft. tall and wide, they
can be interplanted with your perennials.
Maiden Grass "Huron Sunrise" |
Need a backdrop for a beautiful flowering
perennial? Have a bare spot? Want to draw the eye along a certain
path? Need privacy? Annual grasses can fill the order. They come in a variety of prices starting at
about $10. I’ve had pretty good luck
over wintering annual grass in my basement.
Annual grasses can be divided
easily. Perennial grasses take some
pretty serious muscle or a backhoe to divide some of the large clumps. If you don’t want the perennial grass to
spread, make sure you either don’t buy any that even hints at “invasive” or
plant in pots and treat as an annual.

Cut the seed head off in the fall for bouquets
or leave for bird feed. Leaving the
grasses stand over winter insures a safe and warmer hiding place for several
varieties of birds.
Perennial or annual grass is a great
thing to share because it invigorates the clump to have part of the roots dug
out. And in the “yes, it was an odd
winter and I’m still finding crazy things” category: I had three clumps of native “Big Bluestem
Vitman”. One clump almost totally died,
one is only about four foot tall and the third doubled in diameter and is over eighteen
foot tall. Now that’s vertical
amazement!
