What Counts as Indoor Gardening in the UK
Indoor gardening covers any growing done inside the home rather than in a garden or allotment. In the UK, that typically means houseplants on windowsills and shelves, herbs and salad leaves grown in pots in the kitchen, terrariums and bottle gardens, and increasingly, small hydroponic or windowsill growing kits. It can be as simple as a single peace lily on a shelf or as involved as a wall of mixed foliage.
Because UK homes generally get less intense natural light than homes in sunnier climates, and many are heated through autumn and winter, indoor gardening here tends to lean on plants that tolerate moderate or low light and fairly stable indoor temperatures, rather than on plants that need strong, direct sun for long stretches of the day.
Getting Started: Light, Containers, and Watering Basics
A few basics tend to matter more than anything else when starting out indoors.
Light. Most UK homes have rooms with bright but indirect light near windows, rather than the intense direct sun found in hotter climates. Placing plants close to a window, but out of the strongest midday sun and away from direct heat sources like radiators, suits a wide range of houseplants. In darker rooms or over winter, a simple grow light can help some plants, though many common houseplants also cope reasonably well with lower light for stretches of the year.
Containers. Pots need drainage holes, or a layer of gravel or similar material at the base if you’re using a container without one, so roots aren’t left sitting in water. Terracotta pots let soil dry out faster than glazed or plastic ones, which matters for plants that dislike being overwatered.
Watering. Overwatering is one of the more common ways indoor plants come to grief. Checking that the top inch or so of soil has dried out before watering again is a reasonable general approach for many common houseplants, though needs vary by species, season, and how warm the room is.
Best Plants to Grow Indoors in the UK
There isn’t a single definitive “best” plant for UK indoor gardens — it depends on the light available, how much time you want to spend on care, and whether you want flowers, foliage, or something edible. The options below are commonly recommended starting points.
Low-Light and Low-Maintenance Houseplants
Plants often suggested for beginners or lower-light spots include spider plants, snake plants, pothos, and aloe vera. These are generally tolerant of some neglect and don’t need intense direct sun, which suits many UK rooms. Evergreen options such as weeping figs and kentia palms are also commonly sold as houseplants that give year-round greenery. Our houseplant care guide covers several of these easy, low-light picks in more detail.
Flowering Houseplants for Colour
For colour through the UK’s duller months, forced bulbs such as paperwhite daffodils and hyacinths are popular, along with climbing stephanotis and jasmine. African violets and cyclamen are often grown for their flowers too, though African violets in particular can be sensitive to overwatering and need reasonably bright, indirect light. Moth orchids (Phalaenopsis) are a commonly recommended flowering houseplant for beginners, with more demanding orchid types best left until you’re comfortable with the basics. Peace lilies, streptocarpus, and begonias are other options for long-flowering or colourful displays.
Herbs and Edibles on a Windowsill
A sunny kitchen windowsill can support herbs like basil, parsley, chives, and mint, and some gardeners also grow salad leaves or microgreens indoors on trays. These generally need more consistent light than most foliage houseplants, so a south- or west-facing windowsill, or a supplementary grow light, tends to give better results than a dim corner.
Popular Indoor Gardening Styles and Formats
Houseplant Displays and Living Walls
Beyond a few pots on a windowsill, some indoor gardeners build up collections — grouping cacti and succulents for a sculptural look, hanging air plants in small cages, or arranging pots on shelving. At the more involved end, living walls bring a full panel of foliage indoors, though these are a bigger undertaking involving irrigation and ongoing maintenance.
Terrariums and Bottle Gardens
A terrarium or bottle garden is a sealed or part-sealed glass container planted with small, humidity-loving plants such as ferns, moss, and small tropical species. They’re often described as low-maintenance once established, since the enclosed environment holds moisture, though they still need occasional attention and the right spot out of direct, intense sun. If you’re setting one up as part of a group or club session, the ideas in this guide to indoor gardening club activities cover terrarium-building as a shared project.
Windowsill and Hydroponic Growing Kits
Small hydroponic kits and self-contained windowsill growing systems have become more widely available, letting you grow herbs or salad leaves without soil. These can suit kitchens with limited space or light, though results vary by product and by how much light the kit’s location actually gets.
Is an Indoor Garden Worth It?
Whether an indoor garden is “worth it” depends on what you’re hoping to get from it. Many people take up indoor gardening for the look and feel it brings to a home, for a hobby that doesn’t require outdoor space, or simply to grow a few fresh herbs. Houseplants are also commonly associated with general wellbeing benefits, such as giving people something calming to tend to, though claims about air-purifying effects from houseplants in ordinary room conditions are often overstated relative to the research, so it’s sensible not to treat that as the main reason to start.
Costs are usually modest for a few pots and some compost, though they rise with larger setups such as living walls or extensive lighting. For most people starting with a handful of houseplants or a windowsill herb pot, the time and money involved are low enough that it’s a reasonably low-risk hobby to try. For older or less mobile gardeners weighing up whether to start, this guide to indoor gardening activities for elderly gardeners covers accessible plant choices and tools worth considering.
What Is an Indoor Garden Called?
There isn’t one single official term — “indoor garden” is itself a perfectly standard way to describe it, and it’s often used alongside “houseplant garden.” More specific formats have their own names: a terrarium or bottle garden for a planted glass container, a kokedama for a moss-wrapped root ball hung or displayed without a pot, and a living wall (or vertical garden) for a wall-mounted panel of plants. “Indoor garden” is the broad umbrella term that covers all of these.
Seasonal Care Notes for UK Homes
UK indoor gardening has a seasonal rhythm shaped by shorter winter daylight and central heating. In winter, many houseplants slow their growth and need less frequent watering, and rooms near working radiators can dry out faster, so misting or grouping plants together can help maintain humidity for species that want it. Moving plants away from cold windowsills on frosty nights is also a reasonable precaution. In spring and summer, increased daylight generally means more frequent watering and feeding, and some houseplants benefit from spending the warmer months outdoors in a sheltered spot before coming back inside in autumn.
FAQ
What is the best indoor garden in the UK? There’s no single “best” indoor garden — the right setup depends on your space, light, and goals. A windowsill of houseplants, a kitchen herb pot, and a terrarium are all common, valid starting points.
