All fruit develop from flowers. Flowering plants, the modern
edge of vegetative evolution, universally depend on fruit for the success of
their seeds. These truisms shape the botanical definition of fruit, which is
more precise than the culinary one that classifies corn, beans, and tomatoes
with the vegetables. Botanists view fruits more scientifically than do grocers.

Black cherries |
Cherries are ripening now in a bumper crop because of the
season's excellent rain pattern. When fully mature with a deep purplish black
color they offer a zesty if astringent flavor in a pea-sized package. An
experimental sample puts a wine-like taste on your tongue. Trees dispersed throughout
the State Park can flavor your whole loop around Halibut Point.
|
Tupelo drupes |
Like the cherry trees, tupelos also form drupes, seeds inside a stony pit surrounded
by an edible layer that compensates birds for distributing the seeds far and
wide.
|
Tree swallows
plucking bayberry drupes on the wing |
Up and down the shoreline tree swallows are fattening up on
bayberry drupes for their imminent migration.
|
Sumac, the
"Lemonade Tree" |
The tiny drupes of sumac trees make a tangy drink. Steep the
clusters in hot water or dry and store them for winter refreshment. The juice
also inspires an adventurous cocktail.
|
Crabapples |
Fruit of the apple clan are easy to recognize as sweet,
sour, and juicy. The succulent structures grow out of other parts of the flower
than the ovaries, placing them in a category called pomes.
|
Rosa virginiana fruit |
Rose fruit are similarly structured but without appreciable
assets for our diet. Their small size might lead us to think of them mistakenly
as berries rather than pomes.
|
Nightshade berries |
Berries are
produced from the ovary of a single flower in which the outer layer of the
ovary wall develops into a fleshy edible portion. For example bittersweet
nightshade, a vine clambering
malodorously around Halibut Point, is a close relative of
fruit-producing tomatoes, eggplants and potatoes.
|
Grapes |
|
Cranberries |
Grapes and cranberries are among the native berries of
Halibut Point. Bananas, watermelons, and avocados are berries that have not yet
proven hardy here. Pumpkin berries are currently attaining immense bulk in
local gardens.
|
Cedar waxwing eating
honeysuckle berry |
Humanly toxic honeysuckle berries should be left to the
birds.
|
Catbrier berries |
|
Barberries |
Catbrier and barberries produce fruit edible to birds and
potentially to people.
|
Strawberries |
On the other hand the several kinds of strawberries growing
wild on Halibut Point are botanically not true berries. Like raspberries and
blackberries they are derived from a single flower with more than one ovary,
making them aggregate fruit rather
than berries. *
|
Hickory nuts |
When a flower's ovary wall develops into a hard shell it
produces a fruit called a nut with a seed at the center.
|
Fruit of grasses |
Grass seeds also develop within a thickened ovary wall to
form a fruit grain.
|
Devil's beggar-ticks |
You and I have from time to time helped distribute fruit of
the Devil's beggar tick as burrs stuck to clothing.
|
Black
swallowwort |
Black swallowwort enlists the wind in its distribution plan.
|
Juniper
"berries" |
Circling back to a primary botanical distinction, all fruits
come from flower-bearing plants, the angiosperms.
Cone-bearing plants, the gymnosperms
such as pines and junipers, never have flower structures nor, technically,
fruit. Their seeds are not surrounded by fruit tissue. The term comes from the
Greek meaning 'naked seed.'
_____
* Technically a strawberry is an aggregate accessory fruit, meaning that the fleshy part is derived
not from the plant's ovaries but from the receptacle that holds the ovaries.
Each apparent "seed" (achene) on the outside of the fruit is actually
one of the ovaries of the flower, with a seed inside it.
Great photography.
