Juunikiransou, or Ajuga x
mixta, is an interspecific hybrid between Ajuga nipponensis
and Ajuga decumbens; as is the case, hybridization
with another species within the same genus reportedly can occur
relatively frequently in various places. This hybrid species looks
like Ajuga makinoi in shape and color, but a significant
difference lies in the form of their perianth's upper lip. With
A. makinoi, it sharply cut in, but with A. x mixta, not.
Bloom time: April-May. |
