Do you have any suggestions for controlling the spread of some too happy Japanese Anemones? I know they spread by underground roots but do they also spread via seeds? If I put down a barrier how deep should it go?
I have also experienced this in my garden, and it is not difficult to dig up Japanese anemones and either compost them or offer them to fellow gardeners (with a warning!). Anemone x hybrida spreads easily by roots but can be propagated from seed. It is most likely that the spreading of the plant in your garden is mainly rhizomatous (by roots). If you don't want to dig up the occasional clump, you could try getting rid of the plant in areas where you do not want it, and then putting barriers such as plastic edging around the clumps you want to keep, although I think this requires at least as much labor as removing any unwanted anemones. Also, cut off spent flower stalks if you want to avoid seeds. However, the seedheads are flossy and ornamental in winter.
Here is general information on this plant, from Cornell University.
Here is information from University of Minnesota Sustainable Urban Landscape Information Series about edging material (use the search box in the upper right corner and search for 'edging'). This may give you some ideas on ways of containing the spread of the roots.

I am redoing the narrow planting areas (2-3' wide) on either side of our 20' long entry. Garages from next door townhouses butt up against the outer edge on each side, causing morning sun and afternoon shade on one side, and vice versa on the other side. I have picked out some euphorbias, heucheras, and carexes which should do well. I'm wondering if I should have some taller, more dramatic plants to offset these and if you have any suggestions of ones which might work. Also, any bulb ideas would be appreciated.
Have you considered putting up trellises on one or both sides? Then you could grow vines which require little width, but still have the advantage of height. You could also grow taller plants (maybe some grasses like Miscanthus or even a well-restricted--using root barrier--Bamboo) in containers, and keep them shaped to suit the narrow space. Some shrubs and trees are naturally narrow or fastigiate in growth habit.
Here is a list of narrow plants compiled by local garden designer Chris Pfeiffer,c2005. Some will be too wide for your planting area, but you might want to research those that fit the site.
American arborvitae 'Rheingold' (Thuja occidentalis 'Rheingold') 5'h x 3' w
Barberry 'Helmond Pillar' (Berberis thunbergii f. atropurpurea 'Helmond Pillar') 6'h x 2'w
Boxwood 'Graham Blandy' (Buxus sempervirens 'Graham Blandy') 8'h x 1-1/2'w
English yew 'Standishii' (Taxus baccata 'Standishii') 4'h x 1-1/2'w
Irish yew (Taxus baccata 'Fastigiata') 20'h x 4'w
Japanese holly Jersey pinnacle (Ilex crenata 'Jersey Pinnacle') 6'h x 4'w
Japanese holly Mariesii (Ilex crenata 'Mariesii) 3'h x 1-1/2'w
Dwarf yeddo rhaphiolepis (Rhaphiolepis umbellata 'Gulf Green') 3-4'h x 2'w
Heavenly bamboo 'Gulf Stream' (Nandina domestica 'Gulf Stream') 4'h x 2'w
Japanese euonymus 'Green Spire' (Euonymus japonicus 'Green Spire') 15'h x 6'w
There are also a good number of tall perennials you might try, such as (for your afternoon sunny side) Helenium, Verbascum, Baptisia, Eupatorium, and bulbous plants like Allium and Eremurus, and for your shadier morning sun side, Macleaya, Digitalis, Filipendula ulmaria, Anemone hybrida, Actaea (formerly called Cimicifuga), Lilium martagon, Thalictrum, and Veronicastrum.
There are many excellent gardening books you could consult for ideas. Since you have a small, narrow space, I highly recommend local garden writer Marty Wingate's book, Big Ideas for Northwest Small Gardens (Sasquatch Books, 2003). You are welcome to visit the Miller Library, where you can do further research and also borrow books.

Cyclamen start blooming in the fall. Diana Wells, in her book 100 Flowers and How They Got Their Names (Algonquin Books, 1997) reports that Cyclamen's common name is "sowbread" because they were supposedly used to feed pigs. The name cyclamen comes from the Greek "kyklo" meaning circle and probably referring to the seed stalks that curl up to a tight coil as they ripen.
Wells writes about another autumn flower, Japanese anemones. Plant hunter Robert Fortune sent seeds of the plant to England in 1844. He noted these white flowering perennials were often growing on graves in China and remarked Anemone "[a] most appropriate ornament for the last resting places of the dead."
A few other fun books on the lore and history of plants are Cornucopia the Lore of Fruits and Vegetables by Annie Lise Roberts (Knickerbocker, 1998) with colorful photos and recipes and the classic Who named the Daisy, Who named the Rose by Mary Durant (Dodd, Mead & Co., 1976) that gives a folk history of American wildflowers.
