Florida Reimar Grass: A Hidden Gem for Wetland Gardens

If you’re looking to add authentic Florida native charm to your wetland garden, let me introduce you to a delightfully understated grass that deserves more recognition. Florida reimar grass (Reimarochloa oligostachya) might not win any flashy flower contests, but this humble perennial grass has a quiet elegance that makes it perfect for naturalistic landscapes.

What Makes Florida Reimar Grass Special?

This native grass is a true Southeasterner, calling Alabama and Florida home. As a perennial member of the grass family, Florida reimar grass forms low, spreading mats with a fine, delicate texture that adds subtle beauty to wet areas where many other plants struggle to thrive.

You might also see this plant listed under its former scientific name, Reimaria oligostachya, but don’t let the botanical terminology intimidate you – it’s still the same charming native grass.

Where Does It Grow Naturally?

Florida reimar grass has a relatively limited native range, growing wild in Alabama and Florida. This makes it a fantastic choice if you live in these states and want to create a truly regional landscape that reflects your local ecosystem.

A Word About Rarity

Here’s something important to know: Florida reimar grass has a conservation status that suggests it’s somewhat uncommon in the wild. If you decide to add this grass to your garden (and I hope you do!), please make sure you source it from reputable native plant nurseries that grow their stock responsibly rather than collecting from wild populations.

Why Choose Florida Reimar Grass?

This grass shines in situations where many other plants would throw in the towel:

  • Perfect for consistently wet areas in your landscape
  • Excellent for erosion control along pond edges or rain gardens
  • Adds authentic native character to wetland restoration projects
  • Low-maintenance once established in the right conditions
  • Creates natural-looking ground cover with fine texture

Growing Conditions: Keep It Wet!

Florida reimar grass is what we call an obligate wetland species, which is a fancy way of saying it absolutely loves having wet feet. In fact, it almost always occurs in wetland conditions in nature. This makes it perfect for those challenging soggy spots in your yard that leave you scratching your head about what to plant.

For best results, provide:

  • Consistently moist to wet soil conditions
  • Full sun to partial shade (though it tends to prefer brighter conditions)
  • USDA hardiness zones 8-10
  • Well-draining soil that stays consistently moist

Planting and Care Tips

The good news is that once you get Florida reimar grass established in the right spot, it’s quite low-maintenance. Here’s how to set it up for success:

  • Choose a location that stays consistently moist – think rain garden edges, pond margins, or naturally wet areas
  • Plant in spring or early fall when temperatures are moderate
  • Water regularly until established, then let nature take over if planted in appropriate wet conditions
  • Minimal fertilization needed – this grass is adapted to nutrient-poor wetland soils
  • Allow it to spread naturally to form ground-covering mats

What About Wildlife?

While Florida reimar grass might not be a pollinator magnet (it’s wind-pollinated like most grasses), it can provide habitat and nesting material for various wildlife species. Native grasses often support specialist insects that you won’t find on non-native species, making them valuable components of a biodiverse landscape.

Is This Grass Right for Your Garden?

Florida reimar grass is perfect if you:

  • Live in Alabama or Florida and want authentic regional natives
  • Have wet areas in your landscape that need attractive ground cover
  • Are working on wetland restoration or rain garden projects
  • Appreciate subtle, naturalistic beauty over showy displays
  • Want low-maintenance plants that thrive in challenging wet conditions

However, skip this grass if you have dry soil conditions or live outside its natural hardiness range – it simply won’t be happy in those situations.

The Bottom Line

Florida reimar grass may not be the most well-known native plant, but it fills an important niche for gardeners dealing with wet conditions in the Southeast. Its fine texture, spreading habit, and authentic native status make it a valuable addition to naturalistic landscapes. Just remember to source it responsibly and give it the consistently moist conditions it craves, and you’ll be rewarded with a beautiful, low-maintenance ground cover that truly belongs in your regional landscape.
