Philodendron x 'Pluto'

This once very popular hybrid by famed Philodendron horticulturist Bob McColley became rare in cultivation for many years, until its recent reintroduction to the market via tissue culture.  The parent of the 'Caramel Marble' sport, this plant often throws occasional caramel-shaded leaves that eventually fade into a deep, pleasing green as the mature.
