A mellow brick wall enclosed the orchard, a wall beautified by small green ferns, by pink and red valerian, and yellow toadflax.
Here, as in Sicily, the old lava is overgrown with prickly pear and red valerian.
So are the stems of most plants; the stems of the red valerian are round.
The old wall is, however, growing gay with another plant--the red valerian.
We must be careful to remember that it is the red valerian, for there are other valerians.
It grows on walls and rocks, as the red valerian does, but it is a very different plant in appearance.
The stems of the red valerian are tall and upright; those of the Toadflax are slender and drooping.
The earliest British specimen was taken at flowers of red valerian in a garden at Exeter, August, 1868.
Masses of red valerian, and some of the graceful bright rose-bay willow-herb, give colour to the banks and overhang the walls.
It is not spurred as in the case of the red valerian (p. 302), but the base of the tube is pouched on one side.
