No, not all grass is green! While most grasses are green due to chlorophyll, there are some species and varieties of grass that exhibit different colors, either naturally or under certain conditions. Here are a few examples:
Purple Fountain Grass (Pennisetum setaceum 'Rubrum'):
Japanese Blood Grass (Imperata cylindrica 'Red Baron'):
Blue Fescue (Festuca glauca):
Zebra Grass (Miscanthus sinensis 'Zebrinus'):
Pink Muhly Grass (Muhlenbergia capillaris):
Variegated Grass Species:
Drought-Stressed Grass:
These non-green grasses are often used in landscaping for their aesthetic appeal and ability to add color to gardens and natural spaces.
