The Frosty Fern, with its white-tipped leaves that look dusted with frost, is one of the most visually striking houseplants you can bring indoors. But keeping that silvery-white variegation alive requires specific care that many new owners don’t expect.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. I’ve spent years analyzing grower data, studying customer feedback on shipping and survivability, and comparing the exact potting mixes and light requirements different sellers use.
This guide pinpoints the true contenders for the best frosty fern plant, focusing on which sellers pack their plants for survival and which varieties actually hold their color indoors.
How To Choose The Best Frosty Fern Plant
A Frosty Fern isn’t a true fern — it’s a Selaginella species whose leaf tips turn white when exposed to bright, indirect light. The main challenge buyers face is receiving a plant that has already lost its frosting due to low light during shipping or poor potting practices. Here’s what separates a winning purchase from a disappointment.
Pot Size and Root Protection
Frosty Ferns have shallow, delicate root systems. A 2-inch or 2.5-inch nursery pot is standard, but the seller must pack the pot securely so the soil doesn’t shift during transit. Sellers who wrap the pot base or use foam inserts dramatically reduce transplant shock.
Moisture Management at Delivery
Selaginella species demand consistent moisture but despise soggy roots. The best sellers ship with lightly damp sphagnum or a well-draining soil mix that isn’t bone-dry. Dry-out during shipping causes the white tips to brown and curl within 24 hours of arrival.
Variegation Consistency
True Frosty Ferns develop white tips under 12-14 hours of bright indirect light. Many sellers label similar-looking spike moss as “Frosty Fern,” but the white variegation won’t hold without the correct light cycle. Look for sellers who explicitly mention light requirements in their care instructions.

In‑Depth Reviews
1. Two Frosty Fern Spike Moss – Selaginella
This is the Selaginella variety most likely to display the genuine “frosted” white tips when given 12+ hours of bright indirect light. The 2.5-inch pot uses a sandy soil mix that drains freely — critical for preventing root rot in this moisture-loving species. Multiple buyers confirm the plants arrived in good condition with minimal soil disturbance.
Customer feedback highlights that the white variegation is most vivid when the plant is kept evenly moist and in a shaded corner near a north or east-facing window. The seller ships two specimens per order, which makes it easy to experiment with placement or create a small terrarium cluster. The care instructions explicitly call for indirect light and even moisture, which directly supports the frosting effect.
Some reviewers note that the plant is sensitive to intense grow lights — too much direct bulb heat causes the white tips to brown. Using distilled water and a misting routine helps maintain the delicate leaf structure. For buyers serious about keeping the Frosty Fern aesthetic alive, this pair offers the best foundation.
What works
- True Selaginella species holds white variegation with proper light.
- Sandy soil mix prevents waterlogging and root issues.
- Two plants per order for experimentation or gifting.
What doesn’t
- Sensitive to direct artificial light — needs careful placement.
- Some shipments arrive with dried or dead specimens if delayed.
2. Two White Rabbit’s Foot Fern 4″ Pot – Davallia
While not a true Frosty Fern, the White Rabbit’s Foot Fern offers a similar pale, ethereal aesthetic through its fuzzy white rhizomes that creep over the pot’s surface. The 4-inch pots in this pair provide a larger root zone than typical 2-inch starter plants, making this a better option for immediate display without repotting. The organic material in the soil mix supports consistent moisture retention without becoming waterlogged.
Buyers consistently report that these ferns arrived with active new growth and minimal transplant shock. The “rabbit foot” rhizomes are the visual highlight — they demand high humidity to stay white and fuzzy, so a pebble tray or terrarium environment is recommended. The full sun specification in the listing is misleading; in practice, bright indirect light produces the best foliage color and rhizome development.
The two-pack format works well for comparing different growing conditions. One reviewer noted that despite being labeled “full sun,” their fern thrived in a shaded windowsill with morning light only. The key spec to watch is soil type: the sandy mix drains fast, so watering frequency must increase during active growth periods.
What works
- Larger 4-inch pot reduces need for immediate repotting.
- Organic material in soil supports healthy rhizome growth.
- Unique white rhizomes create visual interest even without flowers.
What doesn’t
- Not a true Selaginella — different care requirements.
- “Full sun” spec in listing contradicts best practice for indoor growth.
3. BubbleBlooms Button Fern 4″ Pot – Pellaea rotundifolia
The BubbleBlooms Button Fern offers a dense, rounded leaf structure in a 4-inch nursery pot that contrasts nicely with the spikier Frosty Fern silhouette. The Pellaea rotundifolia species is known for its air-purifying qualities and year-round blooming potential. This plant ships directly from professional local growers, which means the soil and root system are optimized for the current season.
Customer reviews emphasize how well-packaged these ferns arrive — minimal soil spillage, no broken fronds, and consistently moist substrate. The “Air Purification” special feature is supported by the plant’s natural ability to filter indoor air, though it requires a modest light source to maintain photosynthesis. Partial shade is listed as the ideal sunlight exposure, which aligns perfectly with the lighting conditions that cause white-tip variegation in Selaginella species.
The main limitation is that the Button Fern does not produce the frosty white tips that define the Frosty Fern category. It’s a robust, forgiving plant for beginners who want a fern-like aesthetic but don’t want to stress over precise humidity levels. The natural green color stays consistent year-round if the plant receives steady indirect light and moderate watering.
What works
- Well-packaged shipping with minimal frond damage.
- 4-inch pot size is substantial for immediate display.
- Air-purifying qualities add functional value.
What doesn’t
- No white-tip variegation — not a true Frosty Fern.
- Some customers report smaller than expected foliage.
4. BubbleBlooms Fern Variety Assortment (6 pack)
This assortment delivers six different fern varieties in 2-inch pots, giving you a curated collection that includes at least one Selaginella-like specimen capable of developing white tips under proper light. The plants are hand-selected from professional local growers, and the 2-inch pot size is standard for terrarium and fairy garden applications. The natural color and year-round blooming period make this a versatile set for experimenting with different light and humidity conditions.
Customer reviews highlight the professional packaging — the plants arrive hydrated with intact leaves, even when shipped via standard mail. One Arizona buyer noted that the plants survived a mailbox delivery in summer heat because they were shipped early in the week. The assortment allows you to identify which fern in the set responds best to your home’s specific light levels, then propagate that one forward.
The main tradeoff is that the 7-day warranty window is short — any plants that decline after the first week are not covered. Several buyers reported that half the assortment died within 7-10 days, particularly the more sensitive varieties. For collectors who want long-term results, immediate repotting into a humidity-controlled terrarium is advised.
What works
- Hand-selected from growers, high initial plant quality.
- Six varieties allow side-by-side growth comparisons.
- Well-hydrated packaging reduces transit stress.
What doesn’t
- 7-day warranty is very short for live plants.
- Some varieties decline quickly without terrarium conditions.
5. Optiflora Mini Fern Plants (6 pack)
This Optiflora set provides six mini fern varieties in 2-inch pots, grown in peat soil that retains moisture more effectively than standard potting mixes — a strong match for Frosty Ferns that demand consistent humidity. The partial shade recommendation aligns with the lighting needed to trigger white-tip variegation in any Selaginella present in the assortment. The peat soil also provides a more acidic pH, which many fern species prefer for root development.
Buyers consistently praise the packaging and plant health upon arrival. Multiple reviews mention that the plants looked “vibrantly healthy” and “perfectly packaged” even during winter storms, indicating the seller prioritizes shipping speed and insulation. The 6-count format is ideal for populating a large terrarium or fairy garden setup, where the miniature scale creates a naturalistic floor cover.
The downside is the lack of specific species labeling — you may not know which ferns are in the set until they arrive. If you’re specifically hunting for a Selaginella with visible white frosting, this assortment is a gamble. The peat soil also requires careful watering management, as it stays wet longer than sandy mixes and can lead to root rot if overwatered.
What works
- Peat soil holds moisture for humidity-dependent ferns.
- Excellent packaging survives cold-weather shipping.
- Miniature 2-inch pots fit standard terrarium setups.
What doesn’t
- No species-specific labeling — unknown variety mix.
- Peat soil needs careful watering to prevent root rot.
Hardware & Specs Guide
Pot Size and Its Impact
The standard Frosty Fern arrives in a 2-inch or 2.5-inch pot. A 4-inch pot offers more soil volume, which buffers against rapid moisture loss but also increases the risk of overwatering. For Selaginella species, the 2.5-inch pot with sandy soil is the ideal starting point because the smaller root ball establishes faster in new environments.
Soil Mix and Drainage
Frosty Ferns require a mix that drains freely yet holds enough moisture to keep roots damp. Sandy or peat-based soils are common. Peat retains more water and is better for terrariums with no drainage holes. Sandy soil is safer for open pots with bottom drainage, as it prevents standing water.
