If you've scrolled plant listings or collector groups lately, you've probably noticed it: variegated leaves, waitlists, and price tags that would have been hard to imagine a few years ago. It's not just you. Rare houseplant collecting is a real, documented trend, and the reasons behind it say a lot about why so many of us love this hobby.
This post walks through what the research actually says: where the surge started, why "getting more plants" has turned into "building a collection," and what makes a plant rare in the first place. When you're ready to dig into specific varieties, we've linked our other rare plant guides along the way.
TL;DR: The Rare Houseplant Collecting Trend in Short
Garden Media Group's 2026 Garden Trends Report describes houseplants as the "fastest growing category" of collectible items, with Gen Z and Millennials leading the way.
The COVID-19 pandemic helped set the stage: as many people spent more time at home, houseplant spending climbed, and University of Missouri Extension notes variegated plants "became the rage in 2020 and 2021."
A survey of more than 4,000 people in 46 countries, from a research team that included University of Seville researchers, found that 73.7% agreed plants positively influenced their mood during the pandemic, and more than half wanted more plants at home.
Many rare plants are rare because of how they're made: variegated plants can't be grown from seed, and cuttings root slowly, according to University of Missouri Extension.
Collections grow over time, and good lighting helps every plant in one keep growing through every season.
Is Rare Houseplant Collecting Really Trending Right Now?
Short answer: yes. Garden Media Group's 2026 Garden Trends Report, released in September 2025, puts collecting front and center. As reported by Homes & Gardens, the report describes houseplants as the "fastest growing category" of collectible items, and says: "Collecting is making a comeback, especially with Gen Z and Millennials. They're reclaiming individuality through collecting," calling it "a quiet rebellion against disposable culture."
How Did the COVID-19 Pandemic Help Fuel the Rare Houseplant Boom?
A big part of the story starts when many of us began spending more time at home. Gina Pellino, manager of Chelsea Garden Center in Brooklyn, told Modern Farmer in March 2021: "When people started working from home, the desire to green up their spaces became something that was important to them." She also said she'd heard from many customers that "instead of traveling, they stay-cationed and that money went into making their homes more of an oasis."
Research backs up that feeling. A research team that included University of Seville researchers surveyed more than 4,000 people in 46 countries about having plants at home during the pandemic. The study, published in Urban Forestry & Urban Greening, found that 73.7% of respondents agreed plants positively influenced their mood. More than half said they wanted additional plants, and people spent more time caring for their plants than they had before.
The spending followed. The National Gardening Association reported that Americans spent $2.17 billion on indoor plants and accessories in 2021, up from $1.31 billion in 2019, according to a KUNR Public Radio report. A University of Missouri Extension article on houseplant demand cites a 2021 NGA survey finding that "spending on houseplants grew a whopping 30% in 2021 compared to 2020."
The kinds of plants people wanted were changing too. That same Missouri Extension article notes that "variegated selections, with white areas of the leaf, became the rage in 2020 and 2021."
To be clear, none of these sources claims the pandemic alone created rare plant collecting, and the Seville study can't tell us what people did afterward. But together they paint a consistent picture: more time at home, more plants, and a growing appetite for standout varieties. Collecting, as Garden Media Group describes it today, looks like what grew from there.
Why Has "More Plants" Turned Into "Collecting"?
This is where Garden Media Group's report gets interesting. It puts it this way: "Collecting plants is the new Pokémon; rare cultivars, new foliage colors, and variegations are being chased." And then it names the feeling behind it: "Plant collecting taps the same emotions as gaming: achievement, progression, and control. It's slow joy."
In plain terms, that tracks with what a lot of collectors describe. Achievement is finally bringing home the plant you've been watching for months. Progression is watching it unfurl a new leaf and thinking about what to add next. Control is the quiet satisfaction of tending something that responds to your care.
Homes & Gardens' summary of the report also describes people building a "personal museum" of plants at home, and says houseplants have earned their place on the roster of "intentional clutter." A living collection is something that keeps growing and changing for years, which is a big part of the appeal.
What Makes a Houseplant "Rare" in the First Place?
A lot of it comes down to how these plants are made. The Royal Horticultural Society explains that variegated plants are generally selected from a sport, or mutation, of a pure green plant, and the variegated part is then propagated by cuttings, grafting or division to retain its features.
Monstera deliciosa 'Thai Constellation' is a popular and once rare variegated plant sought after by houseplant collectors.
University of Missouri Extension horticulturist Robert Balek adds that variegated monsteras have "genetically stable" variegation, but they can't be grown from seed. They have to be propagated by cuttings, which root slowly, and that raises costs. The same article lists Thai Constellation cuttings at around $100 each, with mature plants at $1,000 or more.
Demand plays a part too. In 2021, rare plant dealer Shane Tan told Homedit, in a study reported by AIPH: "Demand is at an all-time high now, stocks are low worldwide and as people discover more interesting plants...naturally it's going to be competitive, and prices will increase." For a deeper look at the cost side, our guide to understanding variegated plants covers beauty, cost, and care.
Is Rare Houseplant Collecting Here to Stay?
Nobody can promise that, and a trend report is a snapshot of what's happening now, not a guarantee of what happens next. We also can't tell you what any particular plant will be worth down the road.
What we can say is that the motivations named in the research, feeling good at home, expressing your own taste, and the slow joy of watching something grow, don't depend on a plant's price tag. That's a big reason we think collecting is a lovely hobby at any budget.
