A total of12 mugwort assessions (G1to G15) collected from thep rovinces in Northern Viet Namwere characterized on morpholoy, anatomy and flowering. The resuts showed thatthemugwort accessions were rather diverse instem color (green -G13, G14; purple green G1, G2 - and purple -G4), flower color (white and light yellow), plant height (from 32.45 cm in G7 to 148.8 cm in G2), branching (from 7.25 branches/plant in G1 to 29.75 branches/plant in G9), and flowering. Flowering of mugwort started from September (G1, G2) to November (G13, G14) and time from flowering to ripping seeds was onemonth in all of accessions. The high of fertility rate (>90%) of pollenwasobservedin all assessions. Seed shape and 1000 seed mass (0.1 -0.2 g) wereassession-specific.
