Concerning the Leucothoe cultivar 'Little Flames,' I seek detailed technical insights on its cultivation and performance in environments characterized by partial shade. Specifically, I am interested in understanding the plant's optimal soil pH range and moisture management requirements, as well as any documented susceptibilities to pests or diseases under temperate climatic conditions. Additionally, recommendations for suitable propagation techniques and soil amendment practices to enhance growth and longevity would be highly valuable. Any empirical data or peer-reviewed studies that address its winter hardiness and necessary maintenance protocols would also be appreciated.
