Listening to Trees A Crowd, a podcast exploring the ‘56(ish) native trees of the British Isles’, solved one of childhood’s great mysteries for me. Why, when you plant a pip from one type of apple, does it grow into a completely different type of apple tree? The answer — one kind of apple tree will typically cross-pollinate with another variety to pass on a different set of genes — is less interesting than the next bit.
