Meanwhile, keep your eyes open! Mother Nature is full of surprises. Questions that are not fully understood yet include (i) why do Douglas-firs and many other trees produce cones in multi-year cycles as opposed to the same amount every year? and (ii) how do trees communicate with each other to coordinate their "plans" for cone production? You will see that each seed is winged, with the wing several times as long as the seed itself. Tree Seeds for Planting Blue Douglas Fir Seeds Doug-Fir, Red Fir, Oregon Pine, Douglas Pine, Columbian Pine Seeds Hardy Fragrant Evergreen Tree Seeds 20 Pcs. Pry a cone scale outward to reveal the two seeds developing underneath. You can do it with just your thumbnail, or perhaps with the help of scissors. Later in the summer, try taking apart a Douglas-fir seed cone (female cone). At that point-maybe in a month or so-the cone scales will be prominent compared to today (when cone scales are not even visible). This tree is common in the northern andcentral parts of Arizona, southward to northernMexico, and eastward to western Texas. Distribution For current distribution, please consult the PlantProfile page for this species on the PLANTS Website. Within a few weeks or so, the seeds will be developing and will continue developing until they mature in the fall of this year.Ĭone scales will form, with one cone scale covering every two seeds. The deciduousseed cones are 5-9 cm and mature the first season.The seeds have wings that are less than 25 mm. Today, the seed cones (female cones) are as soft as a paintbrush.Īt this stage, the seeds within the seed cones are either (i) not yet in existence, or (ii) tiny at most. Press here to learn more about bracts on cones. It is notable for having the largest (by far) cones in the genus Pseudotsuga, hence the name. ![]() Seed cones: On the Douglas-fir seed cones (female cones), all that are visible are the bracts that will turn into "mousetails" familiar to kindergarten students throughout the Pacific NW. Pseudotsuga macrocarpa, commonly called the bigcone spruce or bigcone Douglas-fir, is an evergreen conifer native to the mountains of southern California. ![]() I've noticed a fine yellow dusting of Douglas-fir pollen on the deck outside my back door. Pollen cones: The Douglas-fir pollen cones (male cones) have either released their yellow dust-like pollen or are just about to release it. My guess is it'll be a light-cone year.Ī relatively small number of green seed cones (female cones) means a correspondingly small number of seeds and, eventually, a small number of seedlings/trees that will be "born" in 2018. The green seed cones (female cones) are far from abundant, but at least I saw a few on several different trees. So Douglas-fir cones are appearing in 2018. The proportion of Douglas fir seedlings (<130 cm height) was <5 in the majority of stands but in four stands, Douglas fir was the most abundant species among seedlings.
