Field Notes
Description:
"Willows all have abundant watery bark sap, which is heavily charged with salicylic acid, soft, usually pliant, tough wood, slender branches, and large, fibrous, often stoloniferous roots. The roots are remarkable for their toughness, size, and tenacity to life, and roots readily grow from aerial parts of the plant.
The leaves are typically elongated, but may also be round to oval, frequently with serrated margins. Most species are deciduous; semievergreen willows; coriaceous leaves are rare, e.g. Salix micans and S. australior in the eastern Mediterranean. All the buds are lateral; no absolutely terminal bud is ever formed. The buds are covered by a single scale, enclosing at its base two minute, opposite buds, alternately arranged, with two small, opposite, scale-like leaves. This first pair soon falls, and the later leaves are alternately arranged. The leaves are simple, feather-veined, and typically linear-lanceolate. Usually they are serrate, rounded at base, acute or acuminate. The leaf petioles are short, the stipules often very conspicuous, look like tiny, round leaves, and sometimes remain for half the summer. On some species, however, they are small, inconspicuous, and fugacious (soon falling). In color, the leaves show a great variety of greens, ranging from yellowish to bluish."
Habitat:
"Almost all willows take root very readily from cuttings or where broken branches lie on the ground. The few exceptions include the goat willow (Salix caprea) and peachleaf willow (Salix amygdaloides). One famous example of such growth from cuttings involves the poet Alexander Pope, who begged a twig from a parcel tied with twigs sent from Spain to Lady Suffolk. This twig was planted and thrived, and legend has it that all of England's weeping willows are descended from this first one.[3][4]
Willows are often planted on the borders of streams so their interlacing roots may protect the bank against the action of the water. Frequently, the roots are much larger than the stem which grows from them."
