sad death of a judas tree

we had a cersis cinensia that we had to move in november 2019. last year it did have some blossom on and then leaves but they dropped off last summer and its been bare since. where can we get a replacement preferably container grown around 4 - 5 ft high?
weve tried on line wih only marginal success.

 

Mine only gets leaves after t blooms which it has just done. Blooms March/April here in Algarve.

 

Are you prepared to go for C. Canadensis or siliquastrum which is, I believe, the true "Judas tree".
