I do not think your tree will be happy indoors, it is a variety which likes damper conditions to grow in. It needs to be outdoors. You could treat it as an annual and grow it indoors until it dies. Although it is described as miniature, and it is at present because of its age, growing outside the miniature willow can grow to quite a sizeable tree.
Yes, I’m in VT and they grow wild around here and are lovely. They are just starting to produce the little catkins now. I just found it odd this didn’t produce more than a few. There isn’t much info on these grafted minis but I have found a few things that say to take the tops branches right back every year, and plant to a larger pot of wanted. Indoors they might get to about 3.5 ft in height. You can keep potted and put outside during the warmer months. Kind of like a bonsai. I guess time will tell.
That is a good idea, treat it like a large bonsai. You will need to keep it topped and thinned to maintain its size and shape. You could possibly look into root pruning when repotting, the same as for large bonsai. There are lots of gardens in Japan with large bonsai trees which you can walk under. After all, a 15ft tree which naturally grows to over 100 ft is a miniature. Plants produce flowers and seeds when they are stressed , to procreate and avoid dying out. Your willow is probably quite happy at the moment. Especially as it will have been grown under ideal conditions. Another reason for producing catkins is maturity, you may get more as it gets older. Should be interesting. Good luck and enjoy.
These things are grafted onto a rootstock and don't actually get noticeably taller. They do, however, get noticeably bushier. You can trim them once the stems reach the ground and also just thin out the stems at their base rather than giving it a buzz cut.
They are hardy down to at least -20C but can be short lived and die for no apparent reason. I had one given to me in my Belgian garden and loathed the way it sat there looking like a dark and dreary Cousin It all summer once the catkins and fresh spring leaf colour were over. Hideously dull.
They do need plenty of root space and also plenty of water so I don't think they make good subjects for pots.
