Our hostas are springing up all over our corner shade garden. Along with the heucheras, heucherellas, oak leaf hydrangea, and Soloman's seal they make this little corner into a garden based on foliage rather than flowers, but that's not to say that hostas don't have interesting flowers. I like to let the hostas run their own course and only cut down the flower stalks after they have formed seed. Growing hostas from seed is something of an experiment that I am still working to accomplish!
Leaf shapes vary quite a bit depending on the variety. These 'Patriot' hostas have a very common hosta leaf shape but are attractive because of their variegation.
Hosta 'Ginkgo Craig'
Also if you are thinking about dividing your hostas now is a good time!
