As many of you know hime ( thats HE MAY NOT HI ME) means princess or in most cases a code word for small . This is a new tree that is a dwarf or at least dwarfish Katsura. I have no idea whether it will be a bit more hardy than it's older sister so I would use the basic Katsura guidelines as your mantra on this very special new intro... It is always nice to see a dwarf version of a much liked taller JM
Winter Hardiness: Zone 5 - Down to -20°
