A beautiful bouquet or a long-lasting flowering plant is a traditional gift for women, but I have recommended that both men and women keep fresh flowers in the home for their beauty, fragrance, and the lift they give our spirits.

I tend to approach giving interviews with the same sense of circumspection and restraint as I approach my writing. That is to say, virtually none. When asked what I made of blogs like my own, blogs written by parents about their children, I said, 'A blog like this is narcissism in its most obscene flowering.'

And I say the sacred hoop of my people was one of the many hoops that made one circle, wide as daylight and as starlight, and in the center grew one mighty flowering tree to shelter all the children of one mother and one father.

The way that social norms become social norms is not through any systematic process. It is through a flowering of an understanding within a culture.

The historical circumstance of interest is that the tropical rain forests have persisted over broad parts of the continents since their origins as stronghold of the flowering plants 150 million years ago.

Rainforests are not confined to the tropics: a good definition is forest wet enough to support epiphytes - plants that grow on other plants. Particularly in the west of Britain, where tiny fragments persist, you can find trees covered in rich growths of a fern called polypody, mosses and lichens, and flowering plants climbing the lower trunks.

The cherry blossom tree is truly a sight to behold, especially when it is in full riotous bloom. There are several varieties of the cherry blossom tree, and while most of them produce flowering branches full of small pinkish-hued flowers, some of them produce actual cherries.

Kanan is a big road through the Santa Monica Mountains. Between mid-March and mid-April, when you get over to the western side of the mountains, it's populated by Spanish broom - this beautiful, yellow, flowering weed that smells the way I imagine it smells along the Yellow Brick Road.

Where humanity is going to find itself in, say, 20, 30, 40, or 50 years would be very difficult to predict, I think. There are moments, of course, when you think that it's going from bad to worse, but there are other moments when you think that human efforts are really flowering into something really fantastic.
