    Rare form of Black Mondo Grass with each leaf narrowly edged in silver, subtle elegance! 6-10” tall evergreen clumps, slow offsetting (hence slow to make those babies to share); sun in cool areas and on coast, part shade elsewhere; enjoys moist soil but will take some dryness. This is one of those ‘tongue on the floor’ plants for plant nerds like me!

    Very rare and equally slow to divide is this version of black mondo grass. The white margin on the leaf is narrow and subtle, but nevertheless gives it a striking appearance.

    As above but with a narrow white edge, pretty cool despite the soap opera name, I've seen this listed for over $50, here's your chance to get one on the cheap. ZONE 5
