Lemandarin is a cross between Citrus tiawanica x (Keraji or Satsuma) It looks like a satsuma. Resistant to soil diseases that have killed my other seedlings. Vigorous.
From the breeder: As far as hardiness my seedling Lemandarin never flinched in
the cold weather until this past brutal weather. It survived at least to
I think 11°F, -12°C degrees and a few 13°F and 14°F, -11 and -10°C events in the past. This
winter it reached its max tolerable temp where it died at 5.5°F, -15°C on
its own roots. Less than a foot away I had a back up graft of it on
flying dragon about 4 feet up that defoliated with branch die back but
is growing back very well. I can attest to that at least when high
grafted it can at least withstand about 6°F, -14°C.
May come true from seed.
Mild lemon flavor.
