If you had to chose only 6 flowers to plant and you want them to last through Spring and Summer for Zone 6?

What would you choose for a nice color and height contrast? I prefer perinneals so I don't have to replant next year..





I love all types, from ornamental grasses, to low laying creeping phlox.. you ideas may me in my yard soon

Perinniels I like:


Black Eyed Susan


Moonbeam Coreopsis


Purple Coneflower


Lambs Ear (for the feel and look of the leaves, I cut back the flowers)





I'd fill in with an annual, like petunias (impatiens if it is a shady area), to ensure lots of color. White and some darker shades.
Reply:Herding Cats have some pretty good choices. I might add verbena and when it gets hot enough (June) I'd add vincas.
Reply:I like tea tree for it's red. I like Tulips, I like daisies but wife doesn't, and renuculas.
Reply:just plain old violets.like what you might find in your lawn ,daffodils, and tiger lilys,and a lily that is called a pink lady or sometimes suprize lilys and then the old tried and true irises.a nice color besides regular blue only blooms once but the blues can and usually bloom 2x's in a season.then just use a bedding plant that comes up for 2 yrs to fill in as you need to,i.e. marrigolds,snaps,pansies
