29. Aesthetic Critique  Personality - Character Is it apt: exactly suitable to its surroundings?

30.  Spontaneity Is it free flowing; not labored, loose but confident, happy, buoyant? (negative example: solid lines and boarders)

33.  Color Do color combinations have crisp oppositions, smooth analogies?

35.  Color continued: Use white near patios - shows up well at night Use white and gray as separators of conflicting colors Warm colors – red, orange, yellow gives illusion of smaller space Cool colors – blue, green, violet gives impression of openness and space

37.  Structure, Form, & Texture Are there clear contrasts, effective relationships, harmonic rhythms?

38.  Neighborhood Does the flower bed integrate with neighboring flower arrangements?

39.  Natural Environment Are varieties used ecologically nested to the sun/shade, sand/clay, wet/dry, cool/hot, and endemic disease facts of life for location?

40.  Practical Maintenance: Is it maintainable? (dead-heading) % Risk: Experiment with less than 10% of entire commitment. Repeat past success! Execution: Can it be simply planted?
