Speckled Alder Flowering

Speckled alder’s flowers are one of the first flowers to open in the spring.  Look for this shrub near streams and ponds.  One of its most distinctive features at this time of year is the presence of last year’s fruit, which look like miniature woody cones.  Also present through the winter, but opening now, are male and female flowers, or catkins.  The pendulous male flowers open and extend when their pollen is ready to be dispersed. Above them are the tiny, maroon female flowers, which are exquisite when viewed through a hand lens. Even though they flower at the same time on the same shrub, the position of the female flowers above the male flowers discourages self-pollination and encourages cross-pollination in this member of the Birch family.
