To get the most out of your mass , include plant with biased foliage , twilight color , berry , attractive ejaculate heads , and miscellanea that bloom at different metre . Combine plant together with complemental colors and contrasting structure or leaf bod for compelling visual involvement .
Consider plant structure:
apply the “ thriller , makeweight , spiller ” rule for designing perennial plant combination . let in an vertical form as a “ thriller ” for height , a succinct mounding variety show as a “ filler ” for volume , and a trailing or background cover perennial as a “ trawl line ” to grow over the side of the pot and chase down .
