Catkins and cones are the blooms of timber and shrubs whose flowers are sorted in a binary trend—female and male. They’re the quiet pleasure of those that discover botanical particulars, and so they reward shut consideration. Many catkins and cones seem weeks, even months, earlier than the loud shouts of forsythia, the effusion of cherry blossom, and the waxy confectionary of magnolia. Some catkins are as acquainted as spring itself (hey, pussy willow), whereas others require pause to determine (sweetfern catkins, swamp cypress cones).
Listed below are a few of our favourite catkins and cones, to develop or to ponder on a spring stroll.
Pussy willows belong to the Salix, or willow genus. (Salicylic acid, from which aspirin is derived, takes its identify from the genus, the place it was first recognized.) Female and male flowers seem on totally different vegetation, and it’s the males that produce the showiest pussy willow catkins.
A dramatic iteration is a cultivar of an East Asian pussy willow, Salix gracilistyla ‘Melanostachys’, whose catkin buds are black, then an intermediate burgundy, earlier than their anthers ripen and lighten with pollen in opposition to a wealthy inexperienced background inside every construction. The impact, with hundreds, is dizzyingly mesmerizing.
Tip: Don’t plant pussy willows the place their shallow and really dense roots can creep into and disrupt septic fields, foundations, water strains and paving. Give ’em room.
Whereas the flowers of weeping willow, Salix babylonica, are normally described as “nondescript” their catkins are vividly fairly in early spring, their lime hue a shade brighter matching the tree’s whippy branches and a shade lighter than its new leaves.

In case your behavior is to stroll in cold-climate wetlands, you might have met clonal thickets of alder (Alnus species), crowding stream and pool edges. Earlier than the native panorama has woken into inexperienced, alder catkins are a coordinated ballet within the lightest breeze. The lengthy catkins are male, whereas the petite, redder catkins are feminine, on the identical plant.
In a light-weight breeze, pendulous catkins and cones move in unison, as male flower clusters slowly ripen to shed pollen, which is normally wind-dispersed.
Towering Daybreak redwoods (Metasequoia glyptostroboides) are festooned with male pollen cones from late winter by means of late spring. The tasseled clusters are full of pollen that ripens because the climate warms, to be launched and dispersed by the wind. By late summer time the inexperienced feminine cones seem on the identical tree, and mature the identical season, releasing their seeds when their cones dry and cut up in late autumn or the next spring.
