小半灌木，高8-40厘米。老枝麦秆黄色，花枝灰白色或灰绿色，被稠密或稀疏的短柔毛，上部及花序和花梗上的毛较多或更密。中部茎叶全形圆形、扁圆形、三角状卵形、肾形或宽卵形，长0.5-3厘米，宽1-2.5厘米，规则或不规则二回掌状或掌式羽状3-5分裂。一、二回全部全裂。一回侧裂片1对或不明显2对，通常3出，但变异范围在2-5出之间。中上部和中下部的叶掌状3-4全裂或有时掌状5裂，或全部茎叶3裂。全部叶有长或短柄，末回裂片线钻形，宽线形、倒长披针形，宽0.5-5毫米，顶端尖或圆或钝，两面同色或几同色，灰白色或淡绿色，被等量的顺向贴伏的短柔毛；叶耳无柄。头状花序小，少数或多数在枝端排成伞房花序或复伞房花序。总苞钟状，直径3-4毫米。总苞片4层，外层卵形或披针形，长1毫米，中内层椭圆形，长2-3毫米。全部苞片边缘白色或带浅褐色膜质，顶端圆或钝，仅外层基部或外层被短柔毛，其余无毛，麦秆黄色，有光泽。边缘雌花5个，花冠长2毫米，细管状，顶端3-(5)齿。瘦果长约1毫米。花果期6-10月。
广布内蒙古、陕西、甘肃、青海、新疆、西藏。生于荒漠及荒漠草原，海拔550-4400米。苏联中亚地区也有分布。
这是一个多型种，有相当多的地区性居群。比较典型的是甘肃会宁地区的居群，植株非常矮小，高仅8厘米，叶极小，长仅0.5厘米，这是一种特定条件下的一种矮化生态型，曾被当作过独立的(Tanacetum aureoglobosum W. W. Smith et Farrer)种。新疆北部的灌木亚菊常表现出更明显的小半灌木性质，叶两面淡绿色，有稀疏的毛，末回裂片线钻形，顶端尖。西藏改则县的植株，更显示出强大的粗壮的主根系，大部分叶倾向于3全裂。而A.gracilis (Hook. f. et Thoms.) Poljak. (Tanacetum gracile Hook. f. et Thoms.) 可能是分布在我国西藏象泉河河谷至克什米尔地区（拉达克）一带的灌木亚菊的另一种变异式样，头状花序更小而更多，基部更多分枝，且分枝大部分木质化。
