I want to redo my landscape in the front of my house.

campanula, rose bushes (can be trimmed to maintain your height requirement) blue indigo, evening primrose, dwarf phlox, choral bells, pinks, hardy geranium, chrysanthemum, potentilla,

I suggest that you take a photo of the front of the house to a local nursery for advice. They know what will thrive in your area and perhaps give you a good price if they sell/plant for you.

Some roses do well in your area. WE also live where winters get lots of snow and cold and mini roses do best here. They also bloom all summer. Small types of evergreen bushes do well as does holly. I love my holly bush! It is green year round and produces the prettiest red berries for the holidays! Some varigated bushes do well also. Go in and talk to you local nursery people, esp. the seniors, they love to help and have much experience for the area.

I like hosta comes up every year and maybe holly bushes

My garden was just north of you in Ontario. I had great luck with all the standards - coreopsis, purple cone flowers (echinacea), black eyed Susan's, poppies, sunflowers, day Lily's, lupins, shrub roses, holly and you can hide a few vegetables in there as well. I'm not keen on having tomatoes in the front but peppers are lovely and colourful. If you have lots of sun there are climbing roses, hollyhocks, morning glorys, beans, sugar snap peas. The list is virtually endless. But I agree with the lady who said take a photo to a garden centre and ask. Don't be shy to change nurseries either if you aren't happy.

I'd encourage you to locate your planting zone, and then Google "Perennial flowers for Zone --." You can plant flowers to attract bees, hummingbirds and butterflies; flowers for cutting; flowers of fragrance; flowers of certain colors; the sky is the limit. The above Hometalkers have made fantastic recommendations, and I would add to the list beebalm, Joe Pyeweed and even milkweed (I love bees and butterflies).

In addition to the advice to visit the local nurseries, Google "Master Gardener" in your area. These people are fantastic resources who volunteer a great amount of their time to help/educate their local gardeners.

my advice is to go on long walks and see what other property owners have planted, on which sides of the house.
