At first glance, 'Edge of Night' seems like any other black mondo grass. Look closely though, and you'll see that each narrow blade has the thinnest edge of ivory, almost a pinstripe effect. Six to ten inches tall and eventually spreading to a foot wide, 'Edge of Night' adds a dramatic flair to container planters, hanging baskets, borders or mass plantings in sun or all-day dappled shade. Mondo grass will become drought tolerant once established in the ground, and is allegedly rabbit- and deer-resistant. Lavender flowers appear in the summer and eventually turn into black berries, adding another layer of texture and interest.
