Thymus serpyllum Elfin Thyme Plant Height: 1/8" - 1/4" This miniature thyme forms a tight solid mat of gray/green foliage that is a perect choice for a lawn replacement. Gorgeous when in bloom with light pink flowers in summer. Creates a versatile groundcover that will cover dry slopes, fill in between stepping stones or creep over a rock. This plant needs sharp drainage to succeed. Over watering will impair growth. Very drought tolerant.
