Conifers are often seen as species whose appearance is unlikely to change over the course of the year.Especially in autumn, many of them behave as if time stood still for them.When deciduous species surprise us with their riot of colors, they usually remain unchanged. This property is usually seen as an advantage, but isn't it worth looking at from a slightly different point of view?
After all, the change in the color of needles and scales may become a desirable feature in our garden, and this process may be considered a regularity in accordance with nature. Of course, it is not about the fact that the coat of most conifers becomes less intense in winter - they often take on gray or brown tones of green or yellow.
First of all, conifers that lose their needles in autumn give very nice color effects.One of the most attractive in this period is larch, whose needles turn yellow.The needles of Japanese larch Larix kaempferi are nicely colored. Another species that discolours its needles is

Taxodium distichum, the needles of which take on striking red-brown colors in autumn.
It is worth remembering that this species grows well in moist soils (tolerates flooding), therefore it feels great near natural water reservoirs.Older swamp cypress plants are completely frost-resistant.
Ginkgo biloba, a species that, in contrast to its coniferous relatives, forms leathery leaf blades instead of pins, changes its color in autumn.
Pine trees have a very attractive group of varieties in the autumn and winter season. This is an interesting relationship that changes the color of the needles as the temperature drops.Green (blue-green) needles gradually turn yellow, and sometimes even yellow-orange.

This effect can be observed especially often in some varieties of Scots pine Pinus sylvestris, e.g. 'Aurea', 'Gold Medal', 'Gold Coin' or 'Aurea Nisbet', as well as dune pine 'Chief Joseph'.All these varieties grow slower than the species and at the age of 10 they reach 1.5 to 2.5 m in height.
Also mountain pine Pinus mugo (mountain pine) has several varieties that turn golden yellow in winter, e.g.'Winter Gold', 'Ophir' or 'Carsten', 'Zundert', 'Dezember Gold'.The above-mentioned varieties have a bushy growth character and at the age of 10 they reach approx. 0.5 m in height and up to 1 m in diameter.

In natural conditions, for example in the forest or in wastelands, we can also come across yellow-tinged specimens of Scots pine in the autumn and winter season.
