It's not intentional, they just don't know the difference. I used to think mistletoe was the same as holly when I was a kid, too.

that´s strange o__o, here mistletoe is very easy to find xD..people say it used to be a very common ingredient for the druidic potions and things like that, so it is said to be a magic plant...but really it is a mean parasit plant that feeds on the sap of common trees, specially old ones...my grandma has a garden with some fruit trees and she always finds mistletoe hanging from a branch...Holly however is rare to find in nature and ive never seen one in gardens except in my grandpas house (from the other side of the family xD) He has a holly in his garden (i dont know where he found it, the tree its old so maybe he buyed it when he was younger and the species wasnt protected), really close to the house, and it grows like crazy. It even touches the house, but my grandpa is not allowed to cut off his own tree cause the forestal police knows he has a holly and he cant even chop some branches cause he risks getting a fine...

my grandpa´s is the only holly i´ve seen in my life...xD

woa.. thats amazing! and yes, you are probably right..maybe too much cold for mistletoe there..i live in Asturias, the north of Spain, where it´s humid but the temperatures are not very extreme...it snows in winter but not very much..it rains a lot, but i dont think it reaches the rainforest level xD...here we have moss but only on the trunks, ground stones and dead falled trees...mistletoe likes high branches and maybe more sun..its common to find it in the meadow trees rather than in the deep forest...
The moss here it´s more like princess mononoke forest moss

Here in Asturias we have oaks, chesnuts, beeches, yews, also some pines... but there are not many evergreen trees....i think mistletoe need big branches without leaves to grow uo, so it cant grow in pines or other conifers..
In my grandmas house it grows on apple and plum trees, and these trees are not very tall, so she only needs a small ladder (she only needs misletoe in Christmas to decorate the house)
But in some cases it is needed to climb the tree xD..I dont know if you have read Asterix comic books?...they are the adventures of a Gallic warrior, who lives in a small village in France...they are very popular in Europe...well, long story short, in the village there is an old druid who makes potions with mistletoe, but he needs mistletoe that grows on oaks..so he really has to climb the trees to get it xD...I´ve grown up knowing the mistletoe as a plant used in potions and medicines (this is actually true, mistletoe has medicinal properties, so the Gallic and other celtic cultures used to appreciate it a lot)

it´s curious how only a little plant has so many references through history and traditions..even in comic books!

xD cedar really smells nice, in fact i have a cedar perfume and i love it xD..in Asturias the most traditional wood is the oak and chesnut tree wood, which are very strong and resistant..traditional houses are made of stones and strong woods like chesnut and oak and it´s also used for furniture.. Anything made from oak or chestnut is able to last a century without any problem...there is also the beech with a more elastic and resistant wood and then there´s yew which have a really good wood..but it is REALLY really slow to use it for anything...in the old days it was used to make bows, but nowadays there are not many yews and they are considered almost a sacred tree...
The fact is that now all these trees are in danger because the grow very slowly and in the XIX century aproximately eucalyptus was introduced by the emigrants who came back, to reforest and to have fast wood but it is a really fast growing tree and it takes all the space from the old native trees, so now we have lots of eucalyptus forest, but our native animals are not able to live in these forests..Besides that a fire in an eucalyptus forest is way more dangerous cause their wood burn very fast...it´s a shame that ancient forests that were deforest for the wood, were lately replaced with these trees that are foreing to our weather, our fauna and our land...nowadays ancient native forest are highly protected, and they keep growing, but it their slow pacient pace...They dont seem to have any rush xD
