What kind of rocks do you need for a rock garden? What patterns should you make? How do you make a model of it

Question

I need the answer ASAP. Im planning to design one and make a model.

Answer 1

I want to be really respectful here; but what might be the critical need in asap?

Why a Model?

Certainly there is more than one suggestion. ROCKS local to you; Rocks collected from various travels; Very unique; very large; etc.

I did a job for a woman in WA who had her entire ROCK garden lined with sea glass as "mulch"

Pattern is a personal choice. Natural might be one way; some sort of trail equating to places and times when/where you found them; Hearts; Butterflys;;; anything.

No offense but is this for a Horticultural design class?
