Forget me nots ….Euro. trash….pretty but so annoying. Tiny Lilac flowers ..terrible seed spreaders.
Karamu… “Caprosma Robusta” from NZ . It smothers all native bush by developing thickets , leaves grow opposite each other on the stem, and it has red berries which drop and grow or are spread by birds in their droppings.
