Flowers to Plant

I have several lists in the back of my planner: restaurants I want to try, books I want to read, etc. Now I have a list of flowers/herbs I want to plant in our new back yard!

• echinacea
• Shasta daisies
• gladiolus
  
• peonies
• dahlias
• hollyhocks
• day lilies
• chocolate daisies
• basil
• rosemary

Now I just need to find out how many of these are drought tolerant and appropriate for quasi-xeriscaping. We want to keep our water usage low but still have an attractive yard.
