Willow and Alder.
The red catkin is likely from a red alder tree (Alnus rubra), which produces reddish catkins in spring. Alder trees are known for their distinctive cone-like catkins and are commonly found in North America.
Cats don't produce catkins. Catkins are slim, cylindral flower cluster with inconspicuous or no petals produced by some plants.
Black alder trees can reproduce through seed production and dispersal. Female catkins containing seeds develop on the tree, which are then dispersed by wind or water. The seeds can germinate in moist soil and grow into new trees.
No, the alder is not coniferous. It belong to the birch family Betulaceae.
The catkin-bearing tree in the birch family is called a Betula tree. Betula trees produce both male and female catkins, which are the tree's reproductive structures.
No, an aspen tree is part of the populus genus. Only the trees from the birch genus (Betulus) produced catkins as the male pollinating adaptation The aspen Populus tremula does produce catkins in late winter and early spring. They are long and grey.
Birch trees are generally more common than alder and elder trees. Birch trees are found in many regions across the world, while alder and elder trees tend to have more restricted distributions.
