Redwood

(Taxodiaceae Sequoia sempervirens)
Adopted in 1937.
California has
designated two
distinct species
Sequoia ,
Taxodiaceae Sequoia
sempervirens,
and the Redwood
, Sequoia
sempervirens, as
its state trees.
Adopted in 1937.
The California
redwood was
designated the
official State Tree
of California by the
State Legislature in
1937. Once common
throughout the
Northern Hemisphere,
redwoods are found
only on the Pacific
Coast. Many groves
and stands of the
towering trees are
preserved in state
and national parks
and forests.
Redwood (Sequoia
sempervirens), also
called coast redwood
and California
redwood, is native
to the central and
northern California
coast, a region of
moderate to heavy
winter rain and
summer fog so vital
to this tree. It is
one of three
important North
American trees of
the family
Taxodiaceae. Close
relatives are the
giant sequoia
(Sequoiadendron
giganteum) of the
Sierra Nevada in
California and the
baldcypress
(Taxodium distichum)
of the southeastern
states.
The coast
redwoods are the
tallest trees in the
world - one reaching
over 360 feet tall
grows in the
Humboldt Redwoods.
One giant sequoia,
the General Sherman
Tree in Sequoia
National Park, is
272 feet high and
more than 36 feet in
diameter and is
widely considered to
be the world's
largest tree
overall.
Description:
- Leaf:
Evergreen, 1/2
to 1 inch long,
linear,
two-ranked and
flattened,
yellow-green to
green, upper
side of needle
has sparse
stomatal bloom
while underside
has two distinct
bands. Leaves on
cone-bearing
branches may be
scale-like.
- Flower:
Monoecious; both
males and
females are very
small and occur
near the ends of
shoots; males
are oblong;
females more
egg-shaped.
- Fruit:
Woody cone, 3/4
to 1 inch long,
reddish-brown,
basically
egg-shaped,
mature in one
season.
- Twig:
Slender, often
drooping,
initially green
and later
turning brown.
- Bark:
Very thick (up
to 1 foot),
deeply furrowed
with rounded
ridges, fibrous,
reddish to
gray-brown.
- Form:
Very large,
tall, straight
tree (over 300
feet) with a
narrow, loose
crown.

Giant Sequoia
(Taxodiaceae
Sequoiadendron
giganteum)
Adopted in 1953.
California has
designated two
distinct species
Sequoia and the Redwood
as its state trees.
The California
redwood was
designated the
official State Tree
of California by the
State Legislature in
1937. Once common
throughout the
Northern Hemisphere,
redwoods are found
only on the Pacific
Coast. Many groves
and stands of the
towering trees are
preserved in state
and national parks
and forests.
Since its
discovery in the
mid-nineteenth
century, giant
sequoia
(Sequoiadendron
giganteum), also
called sequoia,
bigtree, and Sierra
redwood, has been
noted for its
enormous size and
age, and its rugged,
awe-inspiring
beauty. Because the
species has broad
public appeal and a
restricted natural
range, most groves
of giant sequoia
have been accorded
protected status.
Outside its natural
range, both in the
United States and in
many other
countries, giant
sequoia is highly
regarded as an
ornamental and shows
promise as a major
timber-producing
species.
Description:
- Leaf:
Bluish-green;
may be
scale-like and
appressed, or
awl-like and
spreading,
depending on
crown position.
- Flower:
Monoecious;
males egg-shaped
and very
numerous in
spring; females
egg-shaped,
yellowish.
- Fruit:
Oval, woody
cone, 1 1/2 to 2
1/2 inches long,
brown.
- Twig:
Tightly covered
in awl-like or
scale-like
leaves, later
turning
reddish-brown
with scaly bark
as the leaves
fall off.
- Bark:
Very thick (1 to
2 feet) on large
trees, deeply
furrowed with
large rounded
ridges, fibrous.
- Form:
A massive tree
with thick heavy
limbs, 250 to
300 feet tall,
10 to 15 feet in
diameter.
