Just how poisonous is an apple tree?

ISTR the pips contain minute amounts of cyanide ;-)
Not enough to do any harm unless you were to eat them in *vast* amounts,
but they are in the same family as bitter almonds and cherry laurel.

And forget-me-not, and grape hyacinth? Honeysuckle, marigold, peony, privet...

Honeysuckle berries and privet berries are both poisonous. Privet has a
violent purging effect and can be fatal to children.
