Here
is a list of what plants are of note on zoo grounds this
month. Actually I am combining two months because
there is little blooming and those that are will last for
several months. Most of these plants can be found in several
spots in the zoo but the most reliable and easiest to find
is what is given here. The warm season flowering has finished
but the winter blooming plants are beginning. These plants
tend to have fragrant flowers, as they need every trick
to lure the very scarce pollinators this time of year.
They also tend to bloom for extended periods for this reason
as well as the cool weather. I have listed plants that
are showing colorful fruit as well. Listed here are the
most noteworthy:
Throughout
the African Savanna is a broadleaf evergreen shrub that
has both the fruit from last year
and this year’s
flowers. It is the strawberry bush, Arbutus unido. Look
for the small inverted urn-shaped flowers that tell you
it is a member of the heath family (Ericaceae). This
is a well-represented family in the Pacific Northwest
containing
many familiar plants such as salal, pacific madrona,
blueberries, huckleberries, heaths, heathers as well
as rhododendrons
and azaleas. Also check out the area near the giraffe
driveway off the main loop path. There are clusters
of native African
herbs with whorls of orange flowers along the stem. This
is Leonotis leonurus and goes by many common names including
lion’s ear, lion’s claw, lion’s tail,
wild dagga, wildedagga or duiwelstabak (Africans), or
imvovo (Zulu). It is a member of the mint family (feel
the square
stems) and is native the grasslands of South Africa.

In
the Elephant Forest as well as other tropical zones are
Sarcococca hookeriana and S.
ruscifolia. The former
has black berries and the latter dark red. Both of
these Chinese natives are in bud and will open soon to
emit
a lovely fragrance. Also in this area, look for the
Japanese aralia, Fatsia japonica. This plant is usually
noticed
for its large, palm-shaped leaves but this time of
year there are clusters of small white flowers at the
growing
tips.
In
front of the Australasia building are some small Hebe ‘Patty’s
Purple. This New Zealand native has purple flowers
along the stems.
Everyone
is now noticing the beautyberry, Callicarpa bodinieri native to China. Now that the leaves
have
fallen off all
that remains are the clusters of small purple berries.
A good place to see them is around the benches
across from the tiger exhibit.

A
very special plant to take note of, Grevillea
victoriae,
is starting to bloom
and will continue
all winter
in the Australasia zone. A good example of it
is at the
east end
of the path in the open-dry section of the landscape.
This Australian native has clusters of pinkish-orange
flowers
hanging from the ends of the branches. Take a
close look at the flowers. What look like petals are
actually the
sepals (modified leaves that protect the flower
before it opens and collectively comprise the
calyx) that
are fused into a tube that, when the flower is
ready, split
into four segments that curl back to expose the
pistil (female part of the flower). It also demonstrates
an interesting aspect of some flowering plants.
Grevilleas
are protandrous,
which means the pollen (containing male reproductive
cells) is released before the stigma (tip of
the pistil
that and
what receives the pollen) is receptive. This
helps prevent self-fertilization. Nearby is Grevillea ‘Canberra
gem’ blooming, a much lower plant having
small needle-like leaves.
In
Jaguar Cove where the path leads down to gorillas is
a vine growing
out of the high planters. It
is winter jasmine
(Jasminum nudiflorum) native to China. Look
for bright yellow flowers. Further down the path
almost to the
gorilla day shelter on the left is a tall shrub
leaning over
the path. In December it will soon be sporting
a bright yellow
spike of small flowers. This is Mahonia
bealei,
the same genus as our Oregon grape.
The
viburnums are starting their winter show. Look for leatherleaf
viburnum (Viburnum rhytidophyllum)
in front
of the Rain Forest Food Pavilion; David’s
viburnum (V. davidii) at the main loop intersection
south of Zoomazium;
double-file viburnum (V.
plicatum ‘tomentosum)
and Viburnum bodnantense with its rosy fragrant
flowers near
the Activities Resource Center.
Across
the path are small bushes with small leaves that
are spiky and the plant has lavender berries. This
is Pernettya mucronata native
to the Straits of Magellan in Chile.
On the way towards keeper central on the west side of the path are the winter
blooming Camellia sasanqua.
There are both white and pink varieties. |

Check
the native snowberry (Symphoricarpos albas) with white
berries
around the beech
tree in the
South Plaza.
As
I said, there is not a lot blooming these days but what’s
there is choice. Enjoy the changing season.

to
plants that may
be blooming on
zoo grounds.
This may be
affected by weather,
moving or removing
plantings or
other factors. This
