Canna lilies

Canna 'Tropicana' foliage
Cannas (members of the Cannaceae family) are not actually lilies, but for some reason unknown to me, that's what people call them. I just call them beautiful. Their big, colorful leaves remind me of banana trees and their exotic flowers make me think of the tropics.

Even if Cannas never flowered, their variegated foliage would make them worth growing. Look for the green-yellow variegation of 'Pretoria', as you see above, or the red-yellow-pink-green leaves of 'Tropicana' at top. Others like 'Red King Humbert' and 'Wyoming' have mahogany leaves.

Dwarf varieties get 18" to 3 feet tall. Standard varieties reach 4 - 6 feet tall.

Canna flowers may be yellow, orange or red.

In Seattle, cannas are most often grown as annuals. They will over-winter in mild years, but the past few have been too cold for many to survive. Cannas do well in containers and as focal points in mixed borders. When they are blooming, they're a sure sign of summer in Seattle.

Attracting Hummingbird "Tweets"

Long before there was the social media phenomenon called "Twitter," there were avian wonders called hummingbirds, who chase each other through the air, happily "tweeting" at each other. If you would like to "follow" the antics of these charming little creatures, you don't need a computer, a smart phone or a Twitter account. You just have to offer them a few good reasons to visit your neighborhood.

You could set up hummingbird feeders, of course. But it is much more fun to add plants to the garden that will attract the "hummers."

Here are a few suggestions:
Hummingbirds like tube-shaped flowers and apparently are partial to the color red. So this cape fuschia (Phygelius sp.) is a popular choice for hummingbird gardens. Don't confuse this sun-loving plant with hardy and annual fuschias (see below) which are rather more shade-tolerant and belong to a different family, botanically speaking.
Here are the blooms of a hardy fuschia (Fuschia magellanica).

Alstroemeria, also called Peruvian lily, is another favorite.

As is Crocosmia 'Lucifer.'

I don't want to give you the impression that only red flowers attract hummingbirds. They are curious little creatures and seem (at least from what I've observed) willing to visit anything colorful. Then, quick as a flash, they streak across the sky and "tweet" about what they've discovered.

Here are a few more of the long list of plants that will attract hummingbirds: honeysuckle (Lonicera sp.), trumpet vine (Campesis radicans), strawberry trees (Arbutus unedo), Ceanothus, Penstemons, lupines, coral bells (Heuchera sp.), elderberry (Sambucus sp.) and many others. The Sunset Western Garden Book has a detailed listing of plants for hummingbird gardens in its Guide to Plant Selection at the front of the book.

To learn more about attracting wildlife to your garden, I recommend Russell Link's book, "Landscaping for Wildlife in the Pacific Northwest."Link is a wildlife biologist with the Washington Department of Fish and Wildlife, who also happens to have experience in landscape architecture. Although his book is specific to the Pacific Northwest, the general principles he offers can be applied in other regions, too.
