The plants that are going to be the largest 10 years from now should be the largest ones you put in the ground.

You want to have a layered look. You need a fairly wide, sweeping bed to allow for a low front row, a medium-height middle and a third row that is taller.

Remember, everything is going to grow.

You don't want to smother the roots.

The biggest impact from the new plants will be in the first part of this year, but there will be some impact throughout the year.

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.
