Everyone knows what conifers are, don’t we?
They’re evergreens with needles quite than leaves. However what about larches? They’re not evergreen.
And cypresses have scale-like leaves, not needles. And let’s not even discuss monkey puzzle timber!
The reply to the query “what are conifers” isn’t so clear.
These crops are literally outlined by their technique of replica, not their foliage. Many species are certainly evergreens with needle-like foliage, however not all.
What all of them have in widespread is that they produce reproductive cones as a substitute of flowers.
I stay in one of the crucial conifer-dense areas on the earth, and I’ve developed a deep fascination for these crops.
Not solely do a lot of them look lush and inexperienced even through the winter, however they want hardly any upkeep in any respect within the backyard.
I’m simply dying to debate much more about conifers, so with out additional ado, right here’s what we’ll be going over:
What Are Conifers?
There may be one attribute that defines these crops and it’s not the presence of needles or whether or not or not they’re evergreen.
All of them bear cones with seeds inside. In truth, that’s what the phrase conifer means. It’s Latin for conus, that means cone, and ferre, that means bearing. It’s a cone-bearing plant.
All of them have two forms of cones: females and males. The male cones are small, delicate, and comprise pollen.
The feminine cones are bigger, woody, and comprise the seeds. In lots of species, the pollen is carried a brief distance by the wind.
Conifers are gymnosperms, that means they’re woody, seed-bearing crops. All the about 650 current species inside seven genera are woody perennials which are both timber or shrubs.
The overwhelming majority have a single foremost trunk.
They are often low-growing and underneath 9 inches tall, like dwarf Japanese juniper (Juniperus procumbens), and over 300 toes tall within the case of coast redwoods (Sequoia sempervirens).
Most favor full solar and considerably dry soil, and all are wind-pollinated.
The leaves are sometimes needle-like or scale-like, with the needles in both linear or acicular shapes. Most are evergreen, however others are deciduous.
After we say “evergreen” it doesn’t imply they maintain their needles indefinitely, they simply don’t shed them abruptly like deciduous varieties do.
As an alternative, they drop a couple of right here and there which are continually being changed, giving the looks of getting persistent needles that final perpetually.
Many conifers produce sap, additionally known as resin or pitch, which is a pure safety towards pathogens and pests.
Many pests are delay by the perfume of the resin, however they’ll additionally develop into trapped in it in the event that they attempt to feed on the plant.
If one in every of these crops is wounded, it sends resin to the world to flood out pests and pathogens which may trigger infestation or an infection.
Some conifers wish to appeal to birds to their cones to assist unfold the seeds. These will sometimes develop upright cones with brief or non-existent stems.
That permits the birds to simply perch on the department and feed.
Some Examples
The pine (Pinaceae), podocarp (Podocarpaceae), and cypress (Cupressaceae) households make up the biggest conifer households, however there are additionally the Araucariaceae, Sciadopityaceae, Cephalotaxaceae, and Taxaceae households.
All of the needle-laden timber like cedars, Douglas firs, true cypress, firs, junipers, kauri (Agathis), larches, pines, hemlocks, redwoods, spruces, and yews are conifers.
There are deciduous varieties, together with some larches, bald cypress (Taxodium distichum), and daybreak redwoods (Metasequoia spp.).
These will lose their foliage within the fall and develop new leaves within the spring.
Relating to conifers within the backyard, pines, cypress, yews, and junipers are the most well-liked in North America.
The place Do They Develop Wild?
After the final ice age, many conifer species grew to become extinct as a result of flowering crops, that are higher tailored to the hotter circumstances of the trendy local weather, took over.
However there are nonetheless a couple of areas the place flowering crops haven’t managed to outcompete with conifers.
The Pacific Northwest is one space the place conifers thrive and that’s as a result of evergreen leaves want a local weather with an extended, delicate rising season.
In addition they do nicely in areas which have little moisture in the summertime and ample moisture the remainder of the yr. They’ve additionally tailored to develop in poor soil the place flowering timber and shrubs fail to thrive.
You largely discover conifers in colder areas in northern latitudes. The 2 cold-hardiest timber on the earth, the Dahurian larch (Larix gmelinii) and the Siberian larch (L. sibirica) are conifers.
The rarest sort on the earth, the Monterey cypress, comes from a tiny nook of southwest Oregon and northwest California.
There are only a handful native to the Southern Hemisphere. These belong to the Araucaria, Podocarpus, and Agathis genera.
Kind and Replica
Most conifers, at the very least of their pure type, have a conical form with a powerful central chief. This form maximizes the sunshine publicity accessible to the branches and needles.
As talked about, what units conifers aside from flowering crops is how they reproduce. These crops have petalless flowers on inflorescences that make up the immature cones.
All conifers have male cones that comprise the pollen and feminine cones that maintain the flowers and seeds.
The male cones are sometimes delicate, with scales that maintain the pollen inside till it’s able to launch.
As soon as it releases, it’s carried on the wind, water, or by animals and there might be a powerful quantity.
Should you’ve ever stepped outdoors to search out every part coated in yellow powder, you’re most likely taking a look at pollen from a close-by conifer, like a pine tree (Pinus spp.).
The pollen finds a feminine cone, which is often delicate when younger, changing into woody when mature and pollinated.
The scales open to permit the pollen to search out the seeds inside, they usually’ll typically exude a little bit of resin that helps the pollen stick. Then, the scales shut again as much as defend the pollinated seed.
Some seeds are winged to allow them to be carried on the wind and others look forward to birds or different hungry animals to eat them and carry them far and broad.
Should you go for a stroll in a coniferous forest within the spring, you’ll seemingly discover the seedlings popping up in all places.
Most cones are pollinated and drop from the tree in the identical yr, however fairly a couple of take two and even three years to launch the seeds.
You would possibly hear some cones known as “fruits,” similar to these on junipers and yews, however they aren’t technically fruits. They’re cones, they simply have fleshy scales.
Fast Information to Identification
It may be onerous to inform all the assorted conifers aside. Though it’s much more sophisticated than this, you possibly can typically decide which kind it’s based mostly on how the needles connect to the stalk.
If the needles wrap across the twig, it’s seemingly both a yew (Taxaceae household) or a cypress (Cupressaceae household).
Needles with a spherical base that go away behind spherical scars once they fall or are torn off are true firs (Abies spp.).
Tender needles in clusters of 15 or extra that connect collectively on the base by way of a spur are larches (Larix spp.), whereas 15 or extra stiff needles on a spur are true cedars (Cedrus spp.).
Needles in teams of two, three, or 5 with a papery envelope on the base, it’ll be a pine (Pinaceae household). Scales connected to the stem are junipers (Juniperus spp.).
If the needles connect by way of a small peg perpendicular to the stem, you’re most likely taking a look at a spruce (Picea spp.). If there’s a tiny perpendicular stem, it’s seemingly a Douglas fir.
Lastly, if the needle has a little bit of stem that grows parallel to the principle stem, it’s a hemlock (subfamily Abietoideae).

Conifers Are So Cool!
I actually suppose these crops are so cool – they’ve some actually fascinating variations. Wait, now as I’m studying that sentence, I’m realizing that I’m formally a plant nerd.
