The Sill (thesill.com) is one of America's most celebrated and culturally influential plant brands — a direct-to-consumer company founded in 2012 by Eliza Blank that did more than sell houseplants online. It helped start an entire movement. Before The Sill existed, houseplants were an afterthought in the gardening industry: difficult to find online, absent from the aesthetic vocabulary of millennial city dwellers, and sold almost exclusively through garden centers and big-box hardware stores that weren't designed for the demographic Blank understood intimately — young people living in apartments in major cities, craving greenery, but lacking access, knowledge, and confidence.

Blank's founding story is one of the most personal and compelling in the direct-to-consumer landscape. She launched The Sill at 26 years old from a borrowed desk in a tiny walk-up in New York City's Chinatown, using $32,000 in personal savings and a Kickstarter campaign. For the first two years, she bought plants from wholesalers, potted them in her apartment, and hand-delivered orders on the New York City subway. It was five years before she raised institutional money or paid herself a salary. By 2020, she had bootstrapped The Sill to over $1 million in annual revenue — and then the pandemic arrived, bringing a houseplant obsession that swept across an entire nation of homebound people and transformed The Sill from a beloved niche brand into a household name.

The mission that Blank embedded into The Sill from its first day has never changed: bridge the gap between people and plants, because plants make people happier, healthier humans. That mission — stated simply, lived consistently — is what has earned The Sill the loyalty of a community that now spans the United States and beyond, with virtual workshop attendees joining from Spain, Brazil, Australia, and across the globe.

The Founding Story: From Homesickness to Houseplant Empire

The personal depth of The Sill's origin story is important to understand because it explains why the brand resonates so differently from most plant retailers. Blank grew up in rural Massachusetts in a household shaped by her mother — a Filipino immigrant who stayed connected to her roots through gardening. Plants were not decoration in Blank's childhood home; they were culture, comfort, and connection. When she moved to New York City for college and found herself in a bleak, plantless apartment, she experienced the loss of that green world viscerally. Her mother's advice was simple: get some houseplants. The impact was immediate, and Blank became passionate not just about the plants themselves but about the measurable effect that being around living greenery had on her sense of wellbeing, belonging, and happiness.

That personal experience — the daughter of a Filipino immigrant gardener, homesick in a big city, rediscovering herself through plants — is the emotional foundation of The Sill. It is why the brand communicates the way it does: with warmth, accessibility, humor (self-described as lovers of a good plant pun), and genuine belief in the power of the product. And it is why The Sill later celebrated Filipino American History Month with a curated collection of plants native to the Philippines, including the Calamansi Tree — one of the most meaningful product launches in the brand's history, tying directly to Blank's family heritage and the roots of everything The Sill stands for.

The Plant Collection: Hundreds of Varieties for Every Home and Every Life

The Sill's plant collection is organized to help buyers of every experience level find the right plant for their specific situation — a philosophy embedded in the brand's Plant Education approach and reflected in the navigation structure of thesill.com.

Indoor Houseplants remain the core of the business and the category where The Sill has the deepest expertise. The selection spans hundreds of varieties across every care level, light requirement, and aesthetic. Easy-care plants for beginners — pothos, snake plants, ZZ plants, peace lilies, and cast iron plants — are presented with clear guidance and confidence-building messaging that addresses the most common fear among new plant parents: the fear of killing what they buy. Low-light specialists address the reality of apartments and offices where bright indirect light is unavailable. Pet-friendly and non-toxic plants — a category The Sill has been particularly careful to develop and clearly label — serve the enormous segment of plant-loving households with cats, dogs, and other curious animals. Trailing plants, climbing plants, architectural statement plants, and rare and hard-to-find varieties serve the advanced collector who has moved beyond the basics.

Large statement plants and trees are one of The Sill's most significant recent expansions. Fiddle-leaf figs, monstera deliciosa in mature sizes, olive trees, lemon trees, and other large-format plants that anchor a room and define a space are available with The Sill's nationwide shipping — a logistical achievement that requires careful packing protocols to ensure live plants arrive in healthy condition regardless of transit distance.

Outdoor plants and garden represent the brand's most important strategic expansion in recent years. As The Sill's original millennial customer base matured out of city apartments and into homes with porches, patios, stoops, and yards, the demand for outdoor plants grew naturally alongside houseplant expertise. The Sill's outdoor collection now covers fruiting trees (citrus, olive), pollinator-friendly plants, flowering stunners, fast-growing trees, fruit bushes, and layered garden plants suited to creating functional outdoor spaces. By 2026, the brand expects its indoor-to-outdoor business split to approach 50/50, reflecting a fundamental shift in how its customers are living and growing.

Flowering plants and orchids hold a distinct place in the collection. Phalaenopsis orchids — described by The Sill as designed for modern spaces and meaningful gifts — are among the brand's most popular gifting products. The brand's commitment to pet-friendly options extends to its orchid selection, making it a reliable source for buyers who want beautiful flowering plants without risk to their animals.

Planters: Design That Complements the Plant

From its earliest days, The Sill understood that the planter is as important as the plant. Blank sourced her first planters from New York ceramicists, recognizing that the chic, design-forward pot was a key part of what differentiated The Sill from a hardware store plant aisle. Today, The Sill's planter collection spans ceramic planters in a range of colors and sizes, outdoor planters built for weather resistance, and specialty designs that function as interior décor objects in their own right. Plants at The Sill are frequently sold as plant-plus-planter sets, allowing buyers to receive a complete, styled arrangement — no additional shopping required.

Plant Care Accessories and Supplies

The Sill's accessories range covers everything a plant parent needs to keep their collection thriving: premium potting mix, fertilizer packs tailored to specific plant types, grow lights (including Soltech's grow lights, which the brand's Plant Education Lead describes as a game-changer for keeping citrus and olive trees happy indoors), insecticide, plant food, and general wellness supplies. The care accessories category reflects The Sill's commitment to supporting plant parents throughout the entire ownership experience — not just at the point of purchase.

The Plant of the Month Club: Monthly Greenery Delivered to Your Door

The Sill's Plant of the Month Club is a monthly subscription service that delivers a fresh plant paired with a chic ceramic planter directly to subscribers' doors. The club offers two tracks: a Classic track featuring tried-and-true, unique, and sometimes rare varieties suited to collectors and experienced plant parents, and a Pet-Friendly track delivering a new non-toxic houseplant each month for households with animals. The first box is priced at $69; subsequent months are billed monthly with the flexibility to skip, pause, or cancel at any time from the subscriber's account. Subscription boxes ship free. The Plant of the Month Club is also one of the most distinctive and reliable gift options for plant lovers — a standing gift that arrives monthly rather than a single occasion.

Workshops, Education, and Community

The Sill's commitment to education is as central to its identity as its product range. The brand believes that plant ownership should come with the knowledge and confidence to make it succeed — and that accessible, approachable education is what separates a plant that thrives from a plant that dies. In 2025, over 4,000 attendees joined The Sill's virtual workshops from locations across the United States and internationally, including Spain, Brazil, and Australia.

Virtual workshops are available to anyone with an internet connection, covering topics from basic plant care and repotting to specialty subjects like orchid care and transitioning plants between seasons. In-person workshops are held at The Sill's retail locations in New York City and Bethesda, where customers can also shop plants and planters in person, have plants repotted by staff, and pick up orders curbside.

The Sill's free Plant Care Library at thesill.com is a comprehensive resource covering care guides for specific plant varieties, lighting requirements, watering schedules, pest identification, and troubleshooting. A free online course — self-paced and available at any time — provides structured plant care education for beginners. The brand's team of plant experts, led by Plant Education Lead Paris Lalicata, contributes regularly to the Ask the Sill blog, which tracks emerging trends, answers community questions, and reflects on what the brand is learning from thousands of customer interactions.

Guarantee, Shipping, and Customer Experience

The Sill backs every plant purchase with a 30-Day Happiness Guarantee. If a plant arrives damaged or unhealthy, The Sill will replace it at no cost — no complicated returns process, no restocking fees, no penalty for something that went wrong in transit. This guarantee is fundamental to the brand's ability to sell live plants through an e-commerce model, providing the confidence that a significant percentage of potential customers would otherwise lack.

Free standard shipping applies to all orders over $99. Orders under $99 ship for a flat $19 fee. New email subscribers receive 10% off their first order upon signup. The Sill also offers a Rewards Program, corporate gifting services for businesses and offices, and gift cards available in any denomination for buyers who want to give the experience of choosing their own plant.
