Big, bold blooms regularly fill our boutiques at Mayflowers. We love showstopping favorites like lush peonies, romantic garden roses, and vibrant dahlias, but true flower lovers know that not every star bloom needs to be massive.
At Mayflowers, we also adore flowers that might be considered diminutive. Their beauty is reserved for those willing to look closer—to admire, notice, and appreciate the fine details. These are the understated stems that quietly steal the show in a bespoke bouquet.
Our absolute favorite secret weapons: Tweedia.
With its delicate, star-shaped blossoms and rare sky-blue color, Tweedia is the kind of specialty bloom that stops you in your tracks. It’s airy, whimsical, and delightfully unexpected. In a season dominated by warm jewel tones and golden autumn palettes, Tweedia offers a refreshing breath of cool blue.
Below, our team takes a deep dive into everything you need to know about Tweedia—what it is, where it comes from, how our master florists style it, and how to care for your arrangement at home in Northern Virginia.

What is Tweedia? (Botanical Origins & Unique Characteristics)
Tweedia, botanically known as Oxypetalum caeruleum, is a tender perennial flowering plant native to South America, specifically regions across Brazil and Uruguay. It belongs to the Apocynaceae family—the exact same botanical family that includes milkweed, oleander, and vinca.
Its individual blooms are relatively small, typically measuring only about an inch across, but their color makes them completely impossible to overlook. Each blossom features five pointed petals arranged in a neat, starry geometric pattern. While white and pale pink cultivars exist, it is the clear, true sky-blue shade that makes Tweedia a prized gem in high-end floral design.
True blue is one of the rarest colors in the natural flower world. Most "blue" flowers in nature actually lean heavily into violet, purple, or indigo. Because genuine blue hues are so scarce, Tweedia gives our studio an incredible aesthetic edge. Rather than relying on the heavier, denser blue of hydrangeas or the tall spikes of delphinium, Tweedia provides a light, almost ethereal sky blue that feels completely fresh and natural.
The plant itself exhibits a scrambling growth habit with slender stems and soft, oblong, velvety-textured leaves. In floral design, these flexible, delicate stems lend our arrangements an organic sense of movement that stiffer stems simply cannot replicate. It is proof positive that a bloom doesn't need to be huge to command attention.
When Is Tweedia in Season in Northern Virginia?
Given its native tropical and subtropical origins in South America, Tweedia thrives in warm weather and sunny conditions. In our local climate across McLean, Reston, and the broader Northern Virginia area, Tweedia experiences two distinct blooming flushes: late spring and early autumn.
Because it cannot tolerate freezing temperatures, local flower growers cultivate Tweedia as a warm-season annual. In full sun and well-draining soil, it blooms happily throughout the warmest months.
For our florists at Mayflowers, Tweedia’s seasonal availability is a big part of its charm. In an era where many commercial flowers are mass-produced year-round, specialty garden blooms like Tweedia remind us of nature’s natural rhythm. When a bunch of fresh Tweedia arrives, it’s an invitation to pause and celebrate a fleeting seasonal moment.
Why Mayflowers Designers Love Tweedia
At Mayflowers Floral Studio, our signature design aesthetic relies on pairing premium luxury focal flowers with rare accents you won't find at standard supermarket floral department.
"Not too many people know about Tweedia," says May Bernhardt, owner and lead creative designer at Mayflowers. "It has a bit of a funny name, but it is truly an endearing, romantic flower that adds magic to a bouquet!"
Here is why our design team reaches for Tweedia in our studio:
-
Color Balance: A few stems of sky-blue Tweedia cool down warm blush and peach palettes or elevate traditional white-and-green arrangements.
-
Scale & Rhythm: Interspersed between larger blooms like dahlias, ranunculus, or garden roses, Tweedia acts as a visual bridge that draws the eye through the entire design.
The Mayflowers Design Signature: How We Style Tweedia
Instead of forcing Tweedia to compete with large focal blooms, our designers treat it as an artful accent that brings refined movement to custom vase arrangements.
When our master florists craft bespoke arrangements in our McLean and Reston studios, here are a few ways we style this blue wonder:
1. Elevating Soft Romantic Palettes
We pair Tweedia with blush or peach garden roses, focal dahlias, cymbidium orchids, and delicate white cosmos. The cool blue of the Tweedia provides just enough contrast to keep a soft blush-and-cream palette from feeling too predictable or one-note.
2. Building Layered Garden Textures
To create a lush, garden-gathered feel, we cluster Tweedia alongside other high-end, textured accent blooms like butterfly ranunculus, astilbe, Queen Anne’s lace, astrantia, and scabiosa. This creates a rich tapestried effect where every angle of the vase reveals a new detail.
3. Creating Visual Rhythm and Movement
In our signature arrangements, your eye naturally lands on the boldest blooms first—like a soft pink ranunculus or a focal dahlia. Tweedia is positioned so its starry stems trail upward and outward, making the arrangement look as if it is gracefully growing out of the vase.
Perfect Occasions for Tweedia Arrangements
Because of its unique color, delicate structure, and symbolic rarity, Tweedia is a favorite choice for tailored gifting and high-end local events across Northern Virginia:
-
Luxury Wedding Florals & Bridal Bouquets: Tweedia is the ultimate choice for brides looking for an elegant, natural "Something Blue" tucked into their bouquet.
-
Baby Showers & Welcome Home Gifts: Its soft, sky-blue shade makes it a charming addition to celebratory arrangements for welcoming new additions.
-
Corporate Events & Table Centerpieces: In executive settings or private dinners in McLean and Reston, Tweedia adds a touch of artistic, conversation-starting sophistication to table designs.
How to Care for Your Mayflowers Arrangement at Home
Like its relative milkweed, Tweedia releases a milky white sap when stems are cut. Our team properly preps and treats every stem before it leaves our shop, but a few simple steps at home will ensure your arrangement stays vibrant for as long as possible:
-
Check Fresh Water Levels Immediately: When your arrangement arrives via flower delivery to your home or office, top off the water level right away. Water can shift or slosh out of the vase during delivery transport.
-
Change Water Every 2 Days: Keeping the vase water fresh and clear prevents bacterial growth and keeps delicate stems hydrated.
-
Display in a Cool Spot: Position your flowers away from direct sunlight, heating vents, and air conditioners to prolong bloom life.
