Twistedhair Spikemoss: A Rare and Fascinating Native Ground Hugger

Meet twistedhair spikemoss (Selaginella tortipila), one of nature’s most intriguing little characters hiding in the forests of the southeastern United States. Don’t let the name fool you – this isn’t actually a moss at all! It’s a spikemoss, which is more closely related to ferns than to true mosses, making it a fascinating addition to the plant kingdom’s quirky family tree.

What Exactly Is Twistedhair Spikemoss?

Twistedhair spikemoss is a small, perennial plant that looks remarkably like moss but belongs to an ancient group called lycopods or clubmosses. These plants are living fossils, essentially unchanged for millions of years! The twistedhair part of its name comes from its distinctive twisted, scale-like leaves that give it a unique texture and appearance.

As a forb without significant woody tissue, this little ground-hugger stays close to the earth, creating delicate carpets in its native habitat. It reproduces through spores rather than flowers, which makes it quite different from most garden plants you might be familiar with.

Where Does It Call Home?

This native beauty is found exclusively in four southeastern states: Georgia, North Carolina, South Carolina, and Tennessee. It’s perfectly adapted to the specific conditions of this region, thriving in the unique climate and soil conditions of the southeastern forests.

A Rare Treasure Worth Protecting

Here’s something important to know: twistedhair spikemoss is considered vulnerable, with a conservation status of S3. This means there are only an estimated 21 to 100 occurrences in the wild, or between 3,000 and 10,000 individual plants total. That makes it quite rare and precious!

If you’re fortunate enough to encounter this plant in the wild, consider yourself lucky. And if you’re thinking about adding it to your garden, please ensure any plants come from responsibly sourced, nursery-propagated stock – never harvest from wild populations.

Spotting Twistedhair Spikemoss in the Wild

Identifying this little gem requires a keen eye, as it’s quite small and can easily be overlooked. Here’s what to look for:

  • Tiny, scale-like leaves arranged in a distinctive twisted pattern
  • Low-growing, carpet-like growth habit that hugs the ground
  • Preference for moist, shaded areas with rocky or sandy soils
  • Often found in woodland settings with good drainage
  • No flowers – it reproduces via spores like ferns

Is It Beneficial in Gardens?

While twistedhair spikemoss can add unique texture and interest to specialized native plant gardens, it’s quite challenging to grow and has very specific requirements. It thrives in consistently moist but well-draining conditions, preferring shaded areas that mimic its natural forest habitat.

This plant works best in:

  • Rock gardens with native southeastern plants
  • Woodland gardens that replicate natural forest conditions
  • Specialized collections focusing on rare native plants
  • Educational gardens showcasing plant diversity

Keep in mind that twistedhair spikemoss won’t provide the typical pollinator benefits that flowering plants offer, since it doesn’t produce nectar or pollen. However, it does contribute to the overall ecosystem by providing habitat structure and helping maintain the complex web of forest floor life.

The Bottom Line

Twistedhair spikemoss is more of a botanical curiosity than a traditional garden plant. If you’re lucky enough to spot it in its native habitat, take a moment to appreciate this living piece of natural history. For most gardeners, supporting its conservation by protecting its wild habitat and choosing other native ground covers for their landscapes will be the most meaningful way to help this rare species thrive.

Remember, sometimes the best way to love a rare plant is to let it flourish where nature intended – in its wild, native home.
