Cultivation Details

Paulownia kawakamii is a somewhat cold-hardy plant, though it needs to grow in areas with long hot summers in order to fully develop its hardiness. In such regions it is able to tolerate temperatures down to around -10°c when fully dormant, though in areas with cooler summers it can be damaged by considerably less cold conditions. Young plants are also much more susceptible to cold than more mature specimens, whilst the spring growth and flowering of plants of all ages can be damaged by late frosts[
