Woodsia Obtusa: A Little Fern with a Big Personality
I’m Ferb Vu, and I’m obsessed with ferns. Not all ferns, mind you, but there’s something about the Woodsia Obtusa, or Blunt-lobed Cliff Fern, that just captures my imagination. Maybe it’s their tenacity, clinging to life on rocky outcrops. Perhaps it’s their delicate beauty, with fronds that seem to dance in the breeze. Whatever the reason, I’ve been getting a lot of questions about this little fern, so I figured I’d put together a quick FAQ to share what I’ve learned.
What is Woodsia Obtusa?
Woodsia Obtusa is a small, evergreen fern native to eastern North America. It’s most commonly found on cliffs and rocky slopes, where its shallow roots grip the crevices for dear life. The fronds, which are the fern’s leaves, are typically twice-compound, meaning they divide into smaller and smaller segments. These segments are bluntly lobed, hence the nickname “Blunt-lobed Cliff Fern.”
Is Woodsia Obtusa difficult to grow?
Not necessarily! While it thrives in its natural rocky habitat, Woodsia Obtusa can adapt to a garden setting as long as you provide the right conditions. Here’s the key: drainage. This fern hates soggy feet, so well-drained, rocky or sandy soil is essential. They prefer partial shade to full shade and are surprisingly tolerant of drought once established.
How big does Woodsia Obtusa get?
Don’t expect a giant. Woodsia Obtusa is a compact fern, typically reaching only 6-9 inches in height. The spread is minimal as well, making it a perfect choice for rock gardens or container planting.
What are some look-alikes for Woodsia Obtusa?
There are a few ferns that resemble Woodsia Obtusa, but with a keen eye, you can tell them apart. One common look-alike is the Cystopteris fern. Both grow on rocks, but Cystopteris lacks the telltale hydathode (a tiny pore) at the vein tips that Woodsia Obtusa has. Additionally, Cystopteris ferns are not evergreen and typically lack the glandular hairs that cover Woodsia Obtusa.
Can I grow Woodsia Obtusa indoors?
Yes, but it can be a challenge. Woodsia Obtusa needs cool temperatures and high humidity, which can be difficult to maintain indoors. If you’re determined, try a terrarium or a pot with a pebble tray filled with water to increase humidity.
How do I care for Woodsia Obtusa?
Once established, Woodsia Obtusa requires minimal care. Here are the basics:
- Watering: Water deeply when the soil feels dry to the touch, but allow excess water to drain freely. Avoid overwatering.
- Fertilizing: You shouldn’t need to fertilize Woodsia Obtusa very often. A light feeding with a balanced fertilizer once a year in spring is sufficient.
- Winter care: Most Woodsia Obtusa varieties are cold hardy, but if you live in a particularly harsh climate, you can provide some winter protection by mulching around the base of the plant.
Where can I buy Woodsia Obtusa?
Finding Woodsia Obtusa at your local nursery can be tricky. It’s not the most common fern. However, you might have luck at a specialty native plant nursery or online retailers specializing in ferns.
Is Woodsia Obtusa endangered?
The status of Woodsia Obtusa varies depending on the location. While it’s widespread in some areas like Massachusetts, it’s considered rare, threatened, or endangered in other New England states. It’s always best to check with your local conservation department before collecting ferns from the wild.
Conclusion
Woodsia Obtusa might be a small fern, but it packs a punch in the charm department. With its delicate fronds and tenacious spirit, it’s a wonderful addition to any rock garden or shade container. So, if you’re looking for a low-maintenance fern that adds a touch of elegance, consider giving Woodsia Obtusa a try. Remember, with proper care, this little fern can thrive for years to come.
