Nasturtiums are a common plant grown for their pretty flowers. Nasturtium's leaves and flowers are edible and can be used in salads. Nasturtiums attract good insects to the garden and repel bad ones like some caterpillars and are often grown as companion plants around a vegetable garden. Some people call a kind of watercress a nasturtium.
Nectar is the sweet, sticky stuff found in the centre of flowers. It is there to attract insects like bees to the flowers so the bees will pollinate the flowers. Bees use the nectar to make honey, most other birds and insects just eat the nectar as they find it.

Norfolk Island pine trees are a very distinctive type of tree originally only found on Norfolk Island. They grow very well on the coast. They have interesting compound leaves that make long, round straps made up of tiny leaves that look like a scaly snake. The adult trees are symmetrical and are often planted in a line along roadsides. They are not a true pine tree, and will not tolerate cold climates the same way pine trees do.
