Weeping Pussy Willow

The very first flowers that appear in our garden on the onset of Spring is on the Weeping Pussy Willow.  The Salix Caprea ‘Pendula’ is commonly known as the Goat Willow or Weeping Pussy Willow, which belongs to the Caprea genus of flowering trees.
The tree grows pendulous branches and can reach up to 8 feet, while the spread of the tree can also be around 6 feet.
Fuzzy nubs start to appear along the branches, even before the leaves sprout. The reason for this is so that the leaves don’t get in the way of the pollen travelling on the wind, so the chances of pollination are increased.
These nubs are flowers that sprout just before they fully bloom. The soft coating of hairs acts as insulation to protect these early bloomers from cold temperatures. Most other willows make similar flowers, and since they’re among the very first to bloom, they’re especially delightful—they signal the onset of spring. The tree derives its name from these soft silver tufts that resemble a tiny cats’ paws, feeling so much like fur.
Even in full bloom, willow flowers hardly look like flowers at all. They have neither any petals nor any fragrance. Such flowers are called Catkins, derived from old Dutch word Katteken meaning a kitten. Alder, Birch, Beech, Hazel also produce catkins.
Pussy willows are Dioecious, meaning there are both male plants and female plants. Only male plants produce the fuzzy flowers. The flowers on female plants look more like greenish hairy caterpillars.
The male catkins begin to look yellow when the pollens develop on the tips of the anthers.
Catkins usually don’t rely on pollinators to spread their pollen. Instead, they release it into the wind, where it may or may not land on the female flower parts. To hit their targets, the catkins produce a a large volume of pollen. Such massive quantity of pollens released in the atmosphere results in many humans developing allergies and breathing difficulties during this period.
