Memorial tree

Looking for recommendations for a memorial tree.

Sorry if this isn’t the right sub, couldn’t really find a better one.

I’m going to be planting a memorial in the new year and I need to order the tree quite soon.

The tree will be very special to us and we really want a perfect tree.

The tree needs to be native to the UK. We need the tree to last at least 100 years We want the tree to blossom in May, or be at it’s most beautiful in May. We want it to be a good source of food or a good habitat for the wildlife.

Does anyone have any recommendations? Please only recommend one that meets all the criteria.

Thanks in advance for any help
