What does the sentence "To the right and left bushes of some sort, golden and crimson, glowed with the...?

colour, even it seemed burnt with the heat, of fire." mean?

It's a quote from Virginia Woolf's "A Room of One's Own", and I'm not sure if she's saying that she sees bushes that have bright colored leaves, or is something actually on fire?

The context doesn't really help, but it's:

Here then was I (call me Mary Beton, Mary Seton, Mary Carmichael or by any name you please - it is not a matter of any importance) sitting on the banks of a river a week or two ago in fine October weather, lost in thought. That collar I have spoken of, women and fiction, the need of coming to some conclusion on a subject that raises all sorts of prejudices and passions, bowed my head to the ground. To the right and left bushes of some sort, golden and crimson, glowed with the colour, even it seemed burnt with the heat, of fire. On the further bank the willows wept in perpetual lamentation, their hair about their shoulders.
