THREE RHYMING RIDDLES

1)

In days now past, my first reached the floor,

My second you'll find on your head or door;

My whole a plant - of poison sure,

Was drunk by a great philosopher.

2)

My first is a plant that loves to climb,

My second a creature that swims all the time;

My whole you'll find on the kitchen shelf,

Good when mixed, but not by itself.

3)

My first means average,

My second to put on;

My whole a gesture

That helps anger to be gone.
