Here
is a list of what plants are of note on zoo grounds this
month. Most of these plants can be found in several
spots in the zoo but the most reliable and easy to find
is what is given here. Most flowering is over for this
year but there are still a number of interesting and beautiful
plants to take note of. I have listed plants that are showing
colorful fruit as well. Listed here are the most noteworthy
ones:

A
few places around the African Savanna are tall herbaceous
plants that have whorls of orange flowers at each pair
of leaves. 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. Look for them near the lion sculptures. Also
many places around the savanna are strawberry bushes
(Arbutus
unido). These are broadleaf evergreen
shrubs that are sowing clusters of small, white, urn-shaped
flowers as
well as
last year’s fruit. The fruit looks like a strawberry
and is edible but is mealy and not very good tasting.
Also blooming around the Savanna is a lot of thorny Elaeagnus
(Elaeagnus pungens). There is a lot of it near the bridge
at the hippo pool. This is another broadleaf evergreen
with very pale undersides of the leaves. Look for small
white flowers along the stems that have a lovely fragrance.
There are a number of plants in fruit around the Savanna
as well. Along the perimeter fence near the Jimi Hendrix
Memorial viewpoint is autumn berry (Elaeagnus
umbellata)
with lots of small, red berries that are also edible.
Nearby
are several cockspur hawthorn (Crataegus crus-galli)
with thumbnail-size fruits. Near the hippo pool are a
number
of staghorn sumac (Rhus typhina) that have large clusters
of fruits at the branch tips that must remind some people
of deer antlers.

Along
the loop around the emu/wallaroo exhibit most of the
blooms are finished but there are
still some interesting
plants. A very special plant, Grevillea victoriae,
to take note of is almost finished blooming in this zone.
A good
example of it is near the north end of the middle pathway
that takes you through this botanical zone (there are
three pathways all together). Earlier this summer you
may have
noticed the Grevillea ‘Canberra gem’ blooming
with its small needle-like leaves. This is a very different
looking shrub being larger with larger leaves and 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.
In
front of the Australasia building are some small
Hebe ‘Patty’s
Purple. This New Zealand native has purple flowers
along the stems.
Continuing
in Jaguar Cove this month are the princess flowers (Tibouchina
urvilleana).
These Brazilian
natives (very
appropriate for the jaguars) are not winter hardy
in Seattle so are moved out of the exhibit each
winter. They put on
a spectacular show all summer with sensuously soft
leaves and spectacular large purple flowers that
visitors
love.
In the Ceiba spire is the Himalayan honeysuckle
(Leycesteria formosana) that has dark purple berries
at this time
of year.

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. While you
are close to the flower bed near the Activities
Resource Center,
stop and smell the air. As long as the katsura
tree (Cercidiphyllum japonicum) still holds its
leaves, there will be the smell
of cotton candy in the air.
Check
the native bunchberry (Cornus canadensis)
at the entry to the Family Farm. Look for a
groundcover with
lots of bright red berries. Also in this area
is the snowberry
(Symphoricarpos albas) with gleaming white
berries.
There
is not a lot blooming these days but enjoy the changing
season and the remaining
fruits
of summer.
Blooms
at the Zoo is
a general guide
to
plants that may
be blooming on
zoo grounds.
This may be
affected by weather,
moving or removing
plantings or
other factors. This
is only a guide
and
not meant to
illustrate a comprehensive
list of all
plants in bloom
or in the
zoo’s
horticultural collection. |
