Dwarf weeping blossom - 4 ft

Thanks for the suggestion - trust me, all suggestions are much appreciated, particularly as I'm not at all green fingered - but a weeping tree is a must.

Preferably a small, weeping blossom.

Pink would be perfect but I'm struggling to find anything at all...

The image below is a pretty good example of what the Mrs is after - unfortunately this one is in Boise, Idaho and the lady who owns the house has stated it's 4 ft tall and hasn't grown an inch in the pasty 10 years and was very well established when shoe bought the house.

So because my Mrs knows these trees are out there...

 

Hi Zac,
Looking at the picture above suggests to me that the main stem has been lopped at the top in the past as it looks quite flat. This could be the reason for it being small.

 

You have stated the maximum size is 4 ft x 4 ft as you dont want it overhanging your neighbours garden. If the tree pictured is 4 ft hight then its 6ft wide so would do just that and would need pruning to contain it, which would be a shame. Thats why people are coming up with other options for you because gardeners know you will be very hard pressed to find a weeping cherry that will remain inside the 4x4 ft space.
The one pictured may well be the "Snow showers" that is also on the mailordertrees website. You could ask them for the shortest one in stock or even ask them if they could specially graft one onto a shorter stem for you. Would take a while before you would receive that though.
