I took a great landscaping class yesterday night - lord knows I need all the help I can get! It was offered through SCC and was called Mind the Gaps: Ensuring Year-Round Color. It was only $19 and was a little over two hours long.
The instructor had a ton of experience and did a nice job of identifying hardy plants that are good for our zone. I live in southeastern Nebraska so those of you in zone 5 should find this information helpful. Even if you live elsewhere, it's worth skimming over.
The instructor created a handy chart for us that lists which perennials, trees, shrubs, and vines are blooming in each month. Click on the image below to make it bigger. You may need to go to my Facebook or twitter pages, click on the photo, and then download it if it doesn't get large enough through the blog.
I also listed the chart info below if you're having trouble viewing it...

November and December
Perennials: Some perennials persist into fall and winter. Coral Bells, hellebores, & wild ginger often look good for much of winter. Another way to continue interest from your perennials is to not cut all of them all to the ground in the fall. I like to leave plants that have strong stems like coneflowers and goldenrod. They look great with a little frost or light dusting of snow.
Trees: Interesting bark on amur bird cherry, bald cypress, beech, birch, blackgum, kousa dogwood, lacebark elm, paperbark maple, seven son flower, stewartia, sycamore
Shrubs: Interesting bark on harry lauders walking stick, oakleaf hydrangea, yellow and redtwig dogwood. Have berries: cotoneasters, holly, firethorn, winterberry. WitchHazel blooms in the winter. Evergreens give you a spot of color and life.
Vines: Honeysuckle, wisteria and trumpet vines have a nice structure that should be left intact.
Seasonal
Extedend interest in the perennial garden regardless of blooms by focusing on foliage. Combine different leaf colors including: greens, blues, yellows, reds and silvers to have impact during the entire growing season along with different textures and sizes. Plant ferny (soft fluffy textures) foliage, big bold leaves, curly leaves, cut edges. There is even foliage with polkadots (pulminaria). If carefully planned you could have a gorgoeus garden without a single bloom.

I hope you found this useful. Happy landscaping!
