Quote[/b] ]N. villosa is a stunning species, but in keeping with its ultrahighland origin, it requires truly cool conditions to thrive. A temperature range of approximatly 3 C to 18 C is suggested, with high humidity and good illumination. This species is very slow growing and is not a good choice for the novice, or those who are unlikely to invest the long-term effort which its successful cultivation requires. Note that when small, this species is fairly forgiving of overly warm temperatures; however, as it matures, it becomes much more demanding. Therefore, real planning and consideration is recommended prior to undertaking its cultivation. It is one of very few species which we consider truly difficult, but if appropriate conditions are provided, it can be grown quite well.
