Kev qhuas cov curly crown ntawm lub roob tshauv zoo nkauj, ntau tus tsis txawm xav tias nyob rau hauv qhov xwm txheej muaj 84 hom ntawm cov nroj tsuag no, ntxiv los ntawm ntau cov ntaub ntawv hybrid. Rowan tau nyob hauv Northern Hemisphere, tau ua tiav nws thaj chaw huab cua. 34 hom loj hlob nyob rau hauv Lavxias teb sab expanses, ib co ntawm cov uas tau cog thiab siv raws li ornamental shrubs.
Saib qhov sib txawv ntawm ib leeg. Cov xim ntawm berries thiab tawv ntoo, rowan nplooj thiab lwm yam nta yog txawv rau txhua yam. Muaj tsawg heev roob tshauv nyob rau hauv hav zoov, lawv tsis tshua muaj. Yeej, qhov tshwj xeeb kev zoo nkauj ntawm ib tug neeg pleases rowan undergrowth - me me deciduous ntoo 3-6 meters siab.
