Variegated Sweet Flag Grass

Last updated on December 26th, 2024 at 07:34 am

Variegated Sweet Flag Grass is good for the southwest.  It does well and is considered an evergreen grass in warmer regions such as the lower elevations of the Southwest.  Rich yellow and green long leaves that sway back and forth when the days are windy.  The foliage is Variegated which means it has more than one color striped throughout the long grass blades.

How to Care for Sweet Grass

Sweet flag grass (Acorus calamus) is surprisingly low-maintenance if you set it up right. Want it to thrive? Start with rich, damp soil, ideally near water features or in consistently moist areas. Make sure it gets full sun or at least partial shade—too much shade stunts its growth. Water regularly, especially during dry spells, but don’t let the soil completely dry out. Overwatering isn’t usually a problem, as this plant loves wet feet. If you notice dead or damaged leaves, trim them off with sharp shears to keep it looking fresh. Need to control its spread? Divide clumps every couple of years in spring or early fall. Wondering about fertilizers? It usually doesn’t need any, but a light feeding in spring can boost growth.

Where to Plant it?

Plant this great-looking grass in and around ponds, or waterscape designs.  Plant in full sun or partial shade but water more often if planted in full hot sun.  This plant is not a drought-tolerant plant so make sure to give it plenty of water during the mid-summer months—about 3 times per month and 20 minutes each time per week with a good working drip system.  Learn how to plant a tree or shrub. 

It can also tolerate lots of water they will do well in a ponding area or near a water feature.  Height is about 1 ft. tall and 4-6″ wide.  Cut back during the winter season as they will bounce back during the mid-spring seasons.
