About This Plant
Florida Aquatic Nurseries grows the terrarium plant Acorus gramineus 'variegatus'. Also know as variegated Acorus, this terrarium plant is sometimes used as an aquarium decoration. Acorus gramineus 'variegatus' can handle short stays in an aquarium, but must be taken out for rejuvenation periods. Variegated Acorus works well as a pond plant around the edges of a water garden or in moist areas of the yard.
About the Acorus Genus
Family — Acoraceae
Acorus (sweet flag) is a grass-like marginal plant. Despite being sold in the aquarium trade, it is not a true aquatic — submerged leaves slowly decline over a few months and the plant must spend most of its time emergent to thrive.

Difficulty — Intermediate
Grows reliably in moderate-tech tanks. Benefits from steady fertilization and adequate light, but does not require CO2 to survive.
CO2 & Fertilization
CO2 is optional. Growth improves with supplementation, but the plant survives and stays presentable without it.
Tank Size & Setup
Works in tanks 10 gallons and up. Match the plant size to your tank depth for the cleanest aquascape.
Aquascaping & Placement
Place in the midground between foreground carpets and tall background stems. The structure adds visual depth and shelters small fish and shrimp.
Tank-Mate Compatibility
Best suited to paludariums, riparium displays, and pond margins rather than fully submerged community tanks.
Pro Tips for Growing Variegated Acorus
- 1Not a true aquatic — limit submerged stays to a few months, then move emersed to rejuvenate.
- 2Best used as a pond margin or terrarium plant rather than a submerged aquarium plant.
Common Care Issues
Algae on old leaves
Slow growers accumulate dust and spot algae on older leaves. Wipe affected leaves with your fingers during water changes, and consider adding a few Amano shrimp or Otocinclus as cleaners.
Decline after a few months underwater
This species is not a true aquatic and slowly declines when permanently submerged. Move it to a humid emersed setup (paludarium, terrarium, pond margin) for several months to rejuvenate.
Frequently Asked Questions
How much light does Variegated Acorus need?
Variegated Acorus (Acorus Gramineus Variegatus Aquarium) prefers medium lighting. A standard planted-tank LED fixture run 7-9 hours a day is typical.

CO2 is optional. Growth improves with supplementation, but the plant survives and stays presentable without it.
Is Variegated Acorus good for beginners?
Variegated Acorus is rated intermediate-level. Grows reliably in moderate-tech tanks. Benefits from steady fertilization and adequate light, but does not require CO2 to survive.
How fast does Variegated Acorus grow?
Growth rate is extremely slow under water. Be patient — visible new growth may take 3-4 weeks, but the plant is famously low-maintenance once settled.
What fish and invertebrates are compatible with Variegated Acorus?
Best suited to paludariums, riparium displays, and pond margins rather than fully submerged community tanks.
Can Variegated Acorus live fully submerged long-term?
No. Variegated Acorus is not a true aquatic plant and slowly declines after a few months underwater. Use it as a temporary display piece in an aquarium, or grow it permanently in a paludarium, riparium, or pond margin where the leaves can reach air.
