Keraji seedling This is its second winter in the ground, outside. The 2018-2019 winter was pretty cold, and it got killed back to the ground, but this year looks like it's been easier for it. The small seedling is only a little more than an inch high. Keraji is closely related to Satsuma, but more hardy, smaller somewhat more sour fruits, and very seedy. Ichang papeda x kumquat hybrid seedling Sudachi Sudachi is closely related to Yuzu but the fruits are usually picked while still green. These hardy citrus varieties are pretty rare and very hard to find.

It will be a while until they start putting on any growth though.
