Ok I'm in a weird bind here...lol. I have a customer that has a set number of flowers to plant. in two beds that run along their front walk way.. both beds are 18 feet long by 20 inches wide. they have 72 Dianthus flowers that they definatley want to be the edge flowers around both beds. then i have 36 agerathum, 54 snap dragons, and 18 salvia. And I'll be danged if I cant figure out a decent pattern for planting them in the beds where they will work out to be even and spaced the right way. any idea's or pattern guides you guys may have would really be helpful right now. Thanks.
