I have a Euonymus hedge and a weigela growing in front of it. Right at the base, a branch of the euonymus has been in contact with the base of the weigela and they've fused, now I've got euonymus shoots coming from the base of my weigela

Knowledge is knowing that a tomato is a fruit. Wisdom is not putting it in a fruit salad.
Rowans will seed anywhere if conditions are right - including little nooks and crannies in tree branches. Birds 'drop' seed too, which often germinates
It's a place where beautiful isn't enough of a word....
I live in west central Scotland - not where that photo is...
Lizzie, that's what I thought but I looked and studied it for ages, and could not find the rowan trunk. The rowan began a few feet up the oak, as if it had seeded itself, but then I thought that's not possible, and then I thought the oak wouldn't have let another tree grow near it, so how did the 2 trunks combine..
Berries in bird droppings often germinate in leaf litter in the forks or holes in tree trunks so one tree appears to be growing out of another.
I once had a gooseberry bush growing on a pollarded willow. I don't have a photo of it, but I found this picture of a cherry tree growing from a pollarded willow.
Gardening in Central Norfolk on improved gritty moraine over chalk ... free-draining.
It can easily happen. A bird eats the Rowan berries. It then flies on to another tree ..an oak maybe and poops...a neat package of fertilizer plus the seed. The seed may start to germinate in the debris between the branches or the soil between the roots. The oak can do nothing to stop it. It only works if the smaller rowan can get enough water/food to grow. Most tiny saplings growing on a large tree will wither and die. But at the end of the day you have 2 separate trees...the Rowan and the Oak growing together...the oak part will have acorns and the Rowan red berries.
You may like to read about Laburnocytisus_adamii..where 2 different trees have been grafted together...on the one tree you can get both pink flowers and yellow. Laburnum in Fabaceae is one...with yellow flowers The other is Chamaecytisus purpureus,..in Fabaceae with pink flowers. ...it works as they are both in the same family/distant relations.

Think of it in animals...dogs in the family Canidae can mate with other dogs..eg Poodles with Labs..= Labradoodles.
Hope I haven't confused you even more!
