Giant (kapena wokutidwa) thuja ndi mtengo waukulu (pafupifupi 60 m wamtali wamtchire komanso wobzalidwa ndi 16-12 m), wokhala ndi makungwa ofiira ofiira ndi korona wowonda. M'nthawi yozizira, thuja lozunguliridwa limatha kukhala chisanu. Ku Moscow kuli chifanizo cha shrubby chomwe chafika pamtunda wa 2.3 metre ali ndi zaka 16 ndipo ali ndi korona wozungulira mita 1.5.
Nthambi (zazikulu) za nthambi ya arborvitae zimapangidwa mozungulira, nthambi zazing'ono zokhala ndi malangizo a "drooping", nawonso. Thuja lozungulira, mosiyana ndi lakumadzulo, lili ndi masamba ofunda - pafupifupi 1 mm mulifupi, ndipo limakula kwambiri - masentimita onse pa mphukira amakhala ndi ma whorls kuyambira 8 mpaka 10. Mitambo yoyera yamaso oyera yoyera imawoneka pansi. Masamba omwe amapezeka mu ndege amayikidwira mbali iliyonse, mbali - zokhala ndi tiziwalo tating'ono komanso mbali zowongoka. Thujala imakhala ndi ma bulu okwana 10-12 mm okhala ndi mapichesi okhala ndi masamba okumbika pamwamba, omatirira komanso mbewu.
Kwawo kwa chimphona chachikulu thuja ndi madambo omwe ali pagombe la Pacific ku North America. Pangani izi kuyambira mu 1853. Pali mitundu pafupifupi 50 ya chimphona thuja: Zebrina, Whipcord, ndi ena omwe sitimakumana nawo kawirikawiri.
Thuja Whipcord - Iyi ndi mtundu wocheperako wa thuja pafupifupi mita 1.5 kutalika. Chaka chilichonse, imakula msinkhu ndi masentimita 7-10. Mtengowu umakhala wozungulira, wokhala ndi mphukira zazitali (zopindika), zomwe zimapangitsa kuti mabowo azikhala ndi singano zambiri. Malangizowo akuterera, akuthwa, ndiwobiriwira nthawi yotentha komanso "mkuwa" nthawi yachisanu.
Thuja Zebrina (Aureovariegata) - yowerengeka mu 1868. Mosiyana ndi zakutchire, zimamera pang'onopang'ono. Pofika zaka 24, zitha kutalika pafupifupi 3 mita. Chisoti chachifumu chake ndi chofiyira komanso chotsika, nthambi zazitali zopingasa ndi malangizo oti "drooping" Mphukira zazing'ono zimakhala ndi mzere wowoneka ngati kirimu, womwe umayamba kuwoneka bwino.
