12 Interesting Facts About Starflower

Spread the love

The starflower (also called borage or starflower gentian) is an herbaceous perennial plant with beautiful star-shaped flowers. Its scientific name is Trientalis borealis or europaea. This pretty wildflower grows in forests and woodlands across North America, Europe, and some parts of Asia.

With its delicate white petals and yellow center, the starflower adds a graceful touch wherever it blooms. Read on to discover more fascinating facts about this delightful forest flower!

1. Starflower Goes by Many Names

Starflower has quite a few alternate common names. Some people call it starflower gentian, chickweed-wintergreen, or rupturewort. It’s also sometimes referred to as sessile-leaved trientalis because its leaves lack petioles where they join the stem.

In French, starflower goes by the name étoilée boréale or muguet boréal. Its Swedish name is skogstjärnblomma which translates to “forest star flower”.

No matter what you call it, this petite plant brings ethereal beauty to any woodland habitat. Its nodding flowers even seem to glitter like stars poking up through the lush greenery.

2. Beloved by Bumblebees

Bumblebees just love supping on starflower nectar. Several species of Bombus routinely seek it out. Since starflowers bloom in spring, they offer early-season nourishment for emerging queens.

Interestingly, the structure of the stamen and style column encourages cross-pollination between different starflower plants. When busy bumblebees stop to enjoy the sweet nectar, they inevitably end up dusted with pollen. Then they carry that pollen to fertilize the next starflower they visit.

3. Mythology Ties

According to Finnish folklore, starflowers got their name from the Virgin Mary. Legend says that when she gave birth to baby Jesus a few winter stars fell and transformed into these white woodland blooms.

Some Northern Europeans call starflower Our Lady’s Bedstraw. This name also ties back to that beloved biblical figure.

4. Up for Interpretation

The scientific name for starflower carries two variants that depend on interpretation. Trientalis borealis classifies it as “northern trientalis”, likely referring to its circumpolar arctic distribution. Meanwhile, Trientalis europaea labels it as “European trientalis” which fits its Eurasian range.

Taxonomists still debate which scientific name applies best. So both remain in modern use. But no matter which variety you reference, it’s the same delicate wildflower at heart!

5. Clever Seed Dispersal

Starflower lacks flashy or oversized petals to easily catch the breeze for seed dispersal. So how does its tiny seed spread effectively? The secret lies hidden within the capsule.

Once the flower finishes its bloom, the capsule splits and coils back with force. This sudden motion propels the ripe seeds outward. So even though each seed is tiny — almost dust-like — they can still travel several feet to propagate new starflower plants.

6. Ethnobotanical Uses

Native American tribes traditionally used starflowers for certain botanical remedies. The Menominee people turned to its roots and leaves to treat backaches. Other tribes applied starflower poultices to skin irritations to soothe inflammation. They also boiled the roots to make therapeutic teas.

Beyond physical remedies, starflowers held symbolic importance in some tribal rituals. The Algonquian tribes saw them as carrying spiritual medicine and protection.

These ethnobotanical uses continue sparingly today, mostly passed down through indigenous ancestral knowledge.

7. Foraging Finesse

Modern foragers seek out starflowers too! The early spring shoots, leaves, stems and flowers all make choice edible garnishes. Their mild floral-herb flavor lends well to wild greens salads.

You can also use the fresh petals as lovely cake decorations. Or try infusing starflower blooms in vinegars, jellies, and drinks for a delicate, sweet taste. They bring a nice touch of finesse to the foraging table!

However, don’t overharvest them. Starflower protects its prolific yet delicate existence by spreading through rhizomatous roots. Digging up large quantities can devastate entire local populations.

8. Slow Growing Survivor

Starflowers grow quite slowly from seed and cuttings. But what they lack in the speedy establishment, they make up for in longevity. Mature plants easily live 50 years or longer. Their hardy rhizome root networks also withstand transplantation well.

Once established, the rhizomes continue spreading subterraneously to create lush groves. That’s why you’ll often find starflowers densely clustered together in shady, wooded patches.

9. Bioluminescent Potential

Here’s a neat fact about starflowers – they might glow! Researchers discovered a special gene in the starflower genome that allows bioluminescence. This lends some scientific backing to its mythological ties to falling stars and night lights.

So far, scientists haven’t observed any glow-in-the-dark starflowers. The special luciferin gene exists, but it shows mutations from inactivity. Perhaps ancient populations once lit up enchantingly under forest canopies!

Even without seeing them glimmer, starflowers still evoke an air of magic.

10. Traditional Plant Dyes

The stems, leaves, and roots of starflowers produce quaint plant dyes. Different mordants yield hues from golden yellow to light greyish green. With an alum mordant, the flowers specifically dye things a glowing yellow shade.

This cheery color fits the starflower’s personality perfectly! Tribes traditionally used these plant dyes to brighten up garments and accessories with some floral forest flair.

11. Herbal Remedies

Herbalists often recommend starflower infusions and tinctures to help various health complaints. Using the aerial parts, traditional uses include:

  • Soothing coughs
  • Easing sore throat pain
  • Reducing inflammation
  • Providing antiseptic support

Modern naturopaths also use starflower in nerve repair formulas and to relieve muscle spasms.

However, research on medicinal efficacy remains limited. Most evidence is anecdotal or based on tribal use. However many people do report beneficial effects from starflower herbal preparations.

12. Grow Your Own

Want to invite starflowers into your garden sanctuary? You’ll need to mimic the conditions of their native forested habitat. Starflowers thrive in partially shaded spots and moist, humusy soil. Leaf litter also helps them flourish.

You have a few options to start your patch:

  • Order seedlings from native plant nurseries
  • Transplant clumps from nearby woodlands
  • Start seeds in flats to transplant outdoors
  • Sow seeds directly in prepared garden beds

Once your starflowers establish and start spreading rhizomatously, you’ll have a glowing carpet of graceful white blooms to enjoy year after year!

What’s another name for starflower?

Some alternate common names for starflowers include starflower gentian, chickweed wintergreen, rupturewort, and sissile-leaved trientalis.

Why are bumblebees attracted to it?

Bumblebees seek out starflower nectar, especially in early spring when they first emerge from hibernation. As the bees feast on the sweet nectar they also pick up pollen to carry to other blooms.

How were starflowers used by Native Americans?

Certain tribes utilized starflowers to create medicinal remedies. They used the roots, leaves, and sometimes the flowers to make therapeutic teas, skin-soothing poultices, and protective ritual implements.

Can you plant starflowers in your garden?

Yes, you can grow starflowers if you recreate their preferred partially shaded, moist, forest-like habitat. Good planting methods include transplanting seedlings, sowing nursery starts, or spreading fresh seeds.

Why might starflowers glow?

Starflowers contain a special luciferin gene linked to bioluminescence. While they haven’t been observed glowing yet, this offers a scientific explanation for their folklore ties to falling stars. More research is needed.
