Ecosystems in Alaska range from grasslands, mountains, and
tundra to thick forests, in which Sitka spruce (the state tree),
western hemlock, tamarack, white birch, and western red cedar
dominate the landscape. Various hardy plants and wild flowers
spring up during the short growing season on the semiarid tundra
plains.
Many of the plants in Alaska produce spectacular
wildflowers and colorful foliage, providing excellent
opportunities to enjoy native plants from spring through autumn. Native wildflowers have become an important component
of commercial and home landscapes, golf courses, and highway
and mine revegetation projects. This is due, in part, to public concerns about
the environment and plant and water conservation. Landscape
architects have identified water conservation and low
maintenance landscapes as the most significant trends in
landscape design in the 1990s. These trends have resulted in an
increased demand for native plant materials.
Native wildflowers are “generally more tolerant of the
region’s climatic irregularities and require less attention, water,
and fertilizer. They also, if properly established, will self-sow
and persist year after year. Wildflowers
in the landscape have resulted in a 25 to 30% savings in
annual mowing or maintenance costs when compared to plantings
of turfgrasses. Since 1987, wildflowers have been specified for use in all
federal highway landscape projects. In Alaska, Icelandic poppy was sown along highways, but
this species was eliminated in 1989 because it is not indigenous
to Alaska.
The Alaska Fireweed is "Alaska's Calendar." Atypical of most
flowers, the Fireweed blooms from the bottom petals and works
its way up. As the petals open over a course of a few weeks, it
eventually becomes "topped out" and Alaskans regard this as the
sign that summer is nearly over. Vast fields of Fireweed can be
seen throughout Alaska and are the perfect roadside decoration.
Fireweed comes in two varieties: the standard Fireweed plant and
Dwarf Fireweed. Dwarf Fireweed typically grows in more arctic
and harsh areas of Alaska while the standard Fireweed can grow
as high as five and six feet in the warm and sunny climates of
the Kenai Peninsula.
Another favorite wildflower is the Forget-me-not, which also has
the official title as the Alaska State Flower. The Arctic
version of the flower is the more common variety in Alaska and
it coloring is apt for the state. Consisting of a small five-petaled
blue bloom with a yellow "eye," the Forget-me-not is of the same
coloring as Alaska's State Flag. The plant is known to be very
hearty and can grab hold in sandy and gravelly soil. It
flourishes as far north as Barrow on the Arctic Ocean.
Tall Jacob's Ladder wildflowers grow in fields, beside streams
and in wet meadows throughout most of Alaska. Jacob's Ladders
sprout in May and bloom in early June. Each stem usually
produces several small blue flowers.
Perhaps the most exotic flower is found in the Southcentral area
of Alaska including the Kenai Peninsula. The Chocolate Lily,
also known as Indian Rice, is a beautiful rich brown color.
Although the odor is considered unpleasant, the bloom truly
looks chocolately enough to eat. The plant can grow up to 24
inches tall and thrives best in moist lowland meadows. A flower
that often grows along side of the Chocolate lily is the Wild
Iris. Blooming in mid to late June, the Wild Iris often grows in
large fields and meadows with high water content. One of the
best viewing areas for both the Wild Iris and the Chocolate Lily
is the "Eklutna Flats" directly south of the village of Eklutna
along the Glenn Highway. Like the Lily, the Wild Iris is best
viewed in early summer and has a short bloom period.
Another prolific bloom is the Nootka Lupine. The Lupine, with
its deep blue and purplish coloring, can easily be spotted
throughout Alaska. This plant can also grow quite tall (nearly
five feet) and is hearty enough to grow on gravel bars, dry
slopes, as well as meadows. Often seen blooming along the
highways, the Lupine, like the Fireweed, is a popular
photography subject. Areas around the Seward Highway near the
turn off for Portage Glacier are good for photographing Lupine
with the Turnagain Arm and Kenai Mountains as a breath-taking
backdrop.
Mountain Harebells are alpine flowers and can often be found on
rocky slopes of Alaska. In harsh alpine conditions, Mountain
Harebells are quite small and often produce a single flower. The
overall height, including the stem is only 1 to 3 inches. Laying
low on the ground and with tiny leaves, Mountain Harebells are
well adapted to dry and windy climate. At lower elevations, they
can afford to be a little taller and can produce several flowers
per plant.
