I bought it as is a year ago with a white little flower. Autumn then came and it remained a stick for a very long time (top right).
These days its very tall and leafy! It occasionally flowers but not for long.
Is it a prunus? A cherry blossom? Rough memory the label on it said "Prunus" Double White ... Which means nothing to me on my searches.
Could someone identify this plant for me and with a picture of what it will/should look like

Cheers,
