I am not an expert in this field, but I am very interested and have researched to find an answer. I received some assistance from tlooto.com for this response. Could you please review the response below to see if it is correct?

To obtain academic research on the appearance and care methods of Coleus plants, access botanical databases such as JSTOR, PubMed, or Google Scholar. Key search terms include "Coleus plant morphology" and "Coleus cultivation practices." For example, research shows that Coleus requires a minimum daily light integral (DLI) of 10.0 mol m⁻² d⁻¹ for optimal growth [1]. Studies also highlight the impact of salinity stress on Coleus morphology and physiology, indicating that some species are more tolerant [2]. Additionally, practical insights can be found in extension service publications from agricultural universities, which provide science-based care guides for Coleus. Combining these resources will offer a comprehensive understanding of Coleus plant care.
