Rare plants are rare because they've got strange habits.

A lot of plants hate disturbed ground, but these plants like a firing range.

I was like a big clumsy giant trying to do something that flies do better … The flower is probably maybe 1/8 of an inch to 1/4 of an inch across, and it's hard to even see without a magnifying glass. I was having to do it hit or miss like that.

There are only about 4,000 marine-plant species compared with an estimated 250,000 species of terrestrial green plants. Similarly, of the 1.7 million-or-so known animal species, only about one-tenth are from oceans, with most of these living on or close to the bottom in relatively shallow water.

The plants are in a weakened state. Moisture is the key. We need rain.

You should start with what plants you like and see what conditions they require, and think about whether your yard can provide them.
