The message
from Kay Easton contains these words:

There is more than one plant known as huckleberry. the garden
huckleberry that you can grow easily here is the same as/close relative
of black nightshade, which looks like a non-climbing deadly nightshade.
But he shouldn't eat them unless he is sure that what has come up is
what he planted.

Deadly nightshade doesn't climb. Upright plant with leaves similar to
black nightshade, but with quite large dull greenish-purple bell-shaped
flowers and tangerine-shaped black berries with a large green calyx.

Woody nightshade climbs and has tomato-like flowers with blue petals and
a yellow centre, and has trusses of poisonous little red plum tomatoes.

Black nightshade and its big brother the Garden Huckleberry have
similarly shaped flowers with white petals and yellow centres, and
trusses of round black tomatoes and cannot be mistaken for deadly
nightshade, whose fruit grows singly.
