Choosing between indoor plants and garden plants isn’t always straightforward. Your decision depends on several factors: where you live, how much light your space gets, your local temperature range, the soil available to you, how much room you have, and how much time you can dedicate to plant care.
This guide breaks down the differences between indoor plants and garden plants, helping you decide which option suits your home, garden, patio or balcony best. Whether you’re a beginner plant owner or an experienced gardener, you’ll find practical advice to guide your choice, plus a look at where to shop for both from Plants-Depot’s indoor plants and garden plants collections.

What Are Indoor Plants?
Indoor plants grow best in the stable, sheltered conditions found inside a home. They suit bedrooms, living rooms, bathrooms and home offices, bringing greenery into spaces that don’t have access to a garden or outdoor area.
Plants-Depot’s indoor plant range covers several categories to suit different rooms and needs:
- Large indoor plants – statement pieces like the Bird of Paradise or Kentia Palm that fill empty corners
- Small indoor plants – compact options for shelves, desks and windowsills
- Medium-sized plants – a middle-ground choice for tables or floor space
- Easy-care plants – low-fuss varieties such as the ZZ Plant and Snake Plant
- Air-purifying plants – popular choices that add greenery to living spaces
- Shade-loving plants – suited to rooms with limited natural light
- Bedroom plants – calming additions like the Peace Lily
- Living room plants – larger statement plants such as the Swiss Cheese Plant
- Home office plants – compact, low-maintenance options that fit neatly into a working space
- Bathroom plants – varieties that tolerate humidity well
Popular choices among UK plant owners include the Dragon Tree, Money Tree, Swiss Cheese Plant and Bird of Paradise. Each offers a different look, size and care level, so there’s usually something to suit most homes.
What Are Garden Plants?
Garden plants are chosen for life outdoors. They’re suited to gardens, patios, balconies and borders, where they experience natural sunlight, rainfall and the UK’s changing seasons.
Garden plants fall into several broad categories:
- Flowering plants – add seasonal colour to beds and borders
- Shrubs – provide structure and year-round interest
- Trees – such as the ornamental Acer, which suits smaller UK gardens
- Perennial plants – return year after year with minimal replanting
- Ground cover plants – fill gaps and suppress weeds
- Evergreen plants – keep their foliage through winter
- Pollinator-friendly plants – attract bees and butterflies, like lavender
- Low-maintenance plants – suited to busy households or beginner gardeners
- Plants for sunny areas – thrive in south-facing gardens or patios
- Plants for shady areas – suited to north-facing or shaded corners
- Patio plants – ideal for containers on balconies or paved areas
Garden plants such as lavender and Acer trees are widely popular across UK gardens thanks to their adaptability and visual appeal.
Key Differences Between Indoor and Garden Plants
Light: Indoor plants generally rely on filtered or indirect light coming through windows, while garden plants receive direct sunlight that varies throughout the day and across seasons.
Temperature: Indoor environments stay relatively stable year-round, whereas garden plants must cope with the UK’s fluctuating temperatures, including frost in winter.
Humidity: Indoor spaces, especially with central heating, tend to be drier than outdoor air, which can affect certain houseplant varieties.
Watering: Indoor plants need a consistent watering routine since they don’t benefit from rainfall. Garden plants often rely partly on natural rainfall, with additional watering during dry spells.
Soil and drainage: Indoor plants grow in potting compost within containers, requiring good drainage to avoid waterlogged roots. Garden plants grow in outdoor soil, which varies in composition and drainage across different gardens.
Seasonal changes: Garden plants respond visibly to the seasons, flowering, growing or becoming dormant at different times of year. Indoor plants experience milder seasonal shifts.
Space requirements: Indoor plants suit smaller, defined spaces like pots and shelves. Garden plants often need more room to establish roots and spread.
Maintenance: Both types of plants can be low-maintenance or high-maintenance, depending on the specific variety chosen.
Which Plants Are Best for Indoor Spaces?
When choosing plants for home use, consider the following:
- Available natural light – south-facing rooms suit more light-loving plants, while low-light rooms need shade-tolerant varieties
- Room size – larger rooms can accommodate statement plants like the Bird of Paradise, while smaller spaces suit compact options
- Maintenance level – beginners often prefer easy-care plants such as the Snake Plant or ZZ Plant
- Pet and child considerations – some houseplants aren’t suitable around pets or young children, so it’s worth checking before buying
- Desired plant size – think about how much a plant will grow and whether your space can accommodate it long-term
- Interior style – plants can complement your existing décor, from minimalist to jungle-inspired interiors
Easy-care and shade-tolerant plants work well for beginners, while larger indoor plants make a strong visual statement in bigger rooms.
Which Plants Are Best for Gardens and Outdoor Spaces?
Choosing garden plants involves a slightly different set of considerations:
- Sunlight – check whether your garden or patio is sunny, partially shaded or mostly shaded
- Soil type – different plants thrive in different soil conditions, from sandy to clay-based soils
- Garden size – smaller gardens suit compact shrubs and trees like the Acer, while larger gardens can support bigger plantings
- UK weather – hardy plants that tolerate frost and rain are often a practical choice
- Drainage – waterlogged soil can harm many garden plants, so good drainage matters
- Maintenance requirements – low-maintenance plants suit busy schedules, while others need more regular attention
- Patio or balcony conditions – container-friendly plants work well in these settings, offering flexibility without a traditional garden bed
Can Indoor Plants Be Grown Outdoors?
Some indoor plants can tolerate a spell outdoors during warmer months, particularly on a sheltered patio or balcony. However, most houseplants originate from tropical or subtropical climates and aren’t built to withstand UK outdoor conditions.
Frost, cold winds and sudden temperature drops can seriously harm or kill many indoor plant varieties. If you do move a houseplant outside temporarily, it’s worth doing so gradually and bringing it back indoors before autumn temperatures drop.
Can Garden Plants Be Grown Indoors?
Certain garden plants can be grown indoors, particularly in containers, but it isn’t always straightforward. Outdoor plants are typically adapted to natural sunlight levels, temperature changes and space to spread their roots, all of which are harder to replicate inside a home. Before bringing a garden plant indoors, consider its light requirements, expected size and whether your indoor conditions can genuinely support its long-term growth.
Indoor Plants vs Garden Plants: Which Should You Choose?
If you’re still weighing up the two, it often comes down to one simple question: are you decorating a room, or planting a space that sees rain and daylight?
Lean towards indoor plants if your main goal is bringing greenery into a flat, office or a room with no outdoor access, or if you’d rather care for something on a shelf than dig a border.
Lean towards garden plants if you’ve got a patio, balcony or bed to fill, or if you’d like to see something flower, attract bees, or change with the seasons.
Most plant owners end up with a bit of both houseplants for the rooms they spend time in, and garden plants for the outdoor space they look out onto.
Choosing Plants for a UK Home and Garden
The UK’s climate plays a significant role in plant selection. Indoor heating during colder months can dry out the air, affecting certain houseplants, while limited winter daylight may mean positioning plants closer to windows.
Outdoors, gardens across the UK face variable rainfall, a real risk of winter frost, and relatively mild summers compared to warmer climates. Sticking with proven, hardy varieties, established shrubs and seasonal perennials, for example, tends to give better long-term results than experimenting with plants better suited to warmer or drier climates.
Once you know which direction you’re leaning, it’s worth browsing by room or setting rather than the whole collection at once. Furnishing a flat or a single room calls for a different shortlist to refreshing a garden border, so Plants-Depot splits its range accordingly: large indoor plants for statement corners, small indoor plants for shelves and desks, and home office plants for low-maintenance options that suit a workspace. For outdoor projects, the full garden plants range covers everything from shrubs and trees to seasonal flowers.
FAQs
What is the difference between indoor plants and garden plants?
Indoor plants are suited to stable indoor conditions, typically around 15-24°C with filtered light through a window, while garden plants are adapted to direct outdoor sunlight, rainfall and the UK’s seasonal temperature swings, including frost.
Can indoor plants be grown outside in the UK?
Some can tolerate short spells on a sheltered patio during warm summer weeks, but most houseplants originate from tropical or subtropical climates and won’t survive a UK winter outdoors, where temperatures regularly drop below freezing.
Can garden plants grow indoors?
Certain garden plants can adapt to large indoor containers, but they usually need considerably brighter light than a typical room provides and more space to spread their roots than most pots allow.
What are the best indoor plants for beginners?
The Snake Plant and ZZ Plant are common beginner choices because they tolerate being watered as little as once every two to three weeks and cope well with low to medium light.
What are the best low-maintenance garden plants?
Established shrubs, evergreens and hardy perennials such as lavender need little beyond an occasional prune and watering during dry spells, once they’re settled into the soil.
Which plants are best for sunny gardens?
Lavender and many flowering shrubs do best with at least six hours of direct sun a day and well-drained soil, which suits most south-facing gardens and patios.
Which plants are suitable for shady outdoor spaces?
Ground cover plants and shade-tolerant shrubs are better suited to north-facing gardens or spots that get only a few hours of indirect light.
What indoor plants need low light?
The Snake Plant and ZZ Plant are among the few houseplants that can go without direct sunlight altogether, making them suited to rooms with north-facing or small windows.
How do I choose between indoor and garden plants?
Start with where the plant will live: a room with no outdoor access points you towards indoor plants, while a patio, balcony or bed points you towards garden plants. From there, match the light, space and maintenance level to what you can realistically offer.
Are indoor plants easier to maintain than garden plants?
Not automatically. A low-maintenance houseplant can be easier than a demanding flower bed, but a hardy, established shrub can be far less work than a fussy tropical plant kept indoors. It comes down to the specific variety rather than indoor versus outdoor as a rule.
