Bolander’s Spikerush

Bolander’s Spikerush: A Hidden Gem for Wetland Gardens

If you’re looking to create a authentic wetland garden or need a native plant that thrives in those perpetually soggy spots in your yard, meet Bolander’s spikerush (Eleocharis bolanderi). This unassuming little sedge might not win any beauty contests, but it’s a hardworking native that deserves a spot in the right garden setting.

What Exactly Is Bolander’s Spikerush?

Bolander’s spikerush is a perennial grass-like plant that’s actually a member of the sedge family. Don’t worry if you can’t tell the difference between grasses and sedges at first glance—even experienced gardeners sometimes need a second look! This particular species is native to the western United States and has earned its place as a valuable wetland plant.

You might occasionally see this plant listed under its synonym Eleocharis montevidensis var. bolanderi, but Eleocharis bolanderi is the accepted name today.

Where Does It Call Home?

This western native has quite an impressive range, naturally occurring across seven western states: Arizona, California, Colorado, Idaho, Nevada, Oregon, and Utah. It’s adapted to the diverse wetland conditions found throughout these regions, from desert springs to mountain meadows.

Why Consider Growing Bolander’s Spikerush?

Let’s be honest—Bolander’s spikerush isn’t going to stop traffic with showy flowers or dramatic foliage. Instead, it offers something more subtle but equally valuable:

• Native plant benefits: As a true native, it supports local ecosystems and requires no guilt about introducing non-native species
• Problem-solver for wet areas: Those soggy spots where other plants struggle? This spikerush thrives there
• Low maintenance: Once established, it pretty much takes care of itself
• Natural texture: Provides fine, grassy texture that creates beautiful contrast with broader-leaved wetland plants
• Wildlife habitat: Offers structure and cover for small wildlife in wetland settings

Perfect Garden Settings

Bolander’s spikerush isn’t destined for your average perennial border. Instead, consider it for these specialized garden types:

• Rain gardens and bioswales
• Bog gardens and wetland restorations
• Pond and water feature margins
• Native plant gardens with consistent moisture
• Naturalistic landscapes mimicking western wetlands

Growing Conditions and Care

The key to success with Bolander’s spikerush is understanding its wetland nature. This plant has a Facultative Wetland status, meaning it usually grows in wetlands but can occasionally handle drier conditions—though it definitely prefers to keep its feet wet.

Ideal conditions include:

• Consistently moist to wet soil
• Full sun to partial shade
• Hardy in USDA zones 4-9
• Tolerates seasonal flooding
• Prefers neutral to slightly alkaline soil

Planting and Maintenance Tips

Spring is the best time to plant Bolander’s spikerush. Here’s how to set it up for success:

• Plant in areas with reliable moisture—think pond edges or rain garden bottoms
• Space plants 6-12 inches apart for ground cover effect
• Water regularly the first season, though this shouldn’t be challenging given its preferred wet conditions
• Minimal fertilization needed—wetland plants are adapted to nutrient-poor conditions
• Cut back old growth in late winter if desired, though it’s not necessary

The Reality Check

Before you get too excited, let’s set realistic expectations. Bolander’s spikerush is a specialized plant for specific conditions. If you don’t have naturally wet areas or aren’t planning a rain garden or water feature, this probably isn’t the plant for you. But if you do have those challenging wet spots or want to create habitat that supports native wetland ecosystems, this little spikerush could be exactly what you need.

It’s also worth noting that while it provides some wildlife habitat structure, it’s not a major pollinator magnet—it’s wind-pollinated and fairly inconspicuous. Think of it more as a supporting actor than the star of your garden show.

The Bottom Line

Bolander’s spikerush might not be the flashiest native plant you can grow, but it fills an important niche for gardeners working with wet conditions in the western United States. If you’re creating authentic wetland habitat, dealing with problem wet areas, or simply want to support native plant diversity in appropriate settings, this humble sedge deserves consideration. Just make sure you can provide the consistently moist conditions it craves, and you’ll have a reliable, low-maintenance addition to your specialized garden spaces.
