Well, there's a surprise! (a nice one)

Just over 2 years ago I ordered two pink Magnolias - the first year one had leaves, the other nothing - dead. I told the supplier and they replaced it. Last year the replacement had leaves, the original had pink blooms. This year the replacement is blooming - and it's YELLOW! There are at least five buds but this is the most advanced. The original one is a bit behind, buds are coming but nowhere near blooming yet.
