Love white variegation? Trying to collect all the rare Philos? This sibling of the White Princess and White Wizard Philodendron has just what you're looking for! They could all be triplets they're so similar! The White Knight has variegated purple-ish stems. 

Philodendrons will tolerate lower light but grow faster and thrive in bright, indirect light. Water when the top 2-3" of soil feel dry.
