L. nepalense is a very difficult one to grow, even for very experienced species lily growers. Kushi Maya is a whole lot easier, and more robust, too.
L. auratum (and L. auratum var. platyphyllum) will be much easier than L. nepalense, but probably not is robust as Kushi Maya. Mine (in the ground) grow best in high shade and stingy watering. All the oriental lilies (includes L. auratum var. platyphyllum and Kushi Maya) like more acid soil.
