Indoor Flowering Plants

Indoor flowering plants bring colour, and often scent, to the months when the garden outside is resting. Our range is led by three groups: Anthurium andraeanum cultivars in red, pink, purple and near black; Phalaenopsis moth orchids with long-lasting sprays; and citrus plants, from the calamondin orange tree to Meyer lemon and kumquat. Peace lily, Hoya, Paphiopedilum and Hippeastrum complete the selection. These are flowering house plants chosen for life indoors, with blooms that last for weeks or repeat through the year, and orchids and Anthurium make considered gifts.

About Flowering House Plants

Anthurium is our largest line, with andraeanum cultivars such as 'Royal Zizou', 'Karma Purple', 'Karma Black' and 'Yellow Champion' offering a flower colour for most schemes. Phalaenopsis follows, including 'Liberty White', 'Jaguar' and the branching multiflora 'Optifriend', alongside Paphiopedilum slipper orchids and Miltonia. Our citrus includes Citrus × microcarpa 'Calamondin', Citrus × limon 'Meyer', kumquat, limequat, makrut lime and sweet orange. Peace lily cultivars such as 'Bingo Cupido', Hoya carnosa with its waxy flowers and glossy foliage, Medinilla magnifica, Clivia miniata and potted Hippeastrum bulbs complete the range.

Anthurium and Phalaenopsis want bright, filtered light: an east window, or a south window behind sheer curtains, at a temperature of 16 to 24°C. Check soil moisture before watering Anthurium and let the top few centimetres dry; water orchids when the roots in their bark turn silver, then drain fully so nothing sits in the saucer. Grouping plants raises humidity and supports healthy growth. Citrus, shrubs of warmer climates, differs: these plants require full sun, a free-draining compost and a cool, bright winter at 10 to 15°C, with time outdoors in the summer months.

Central heating, draughts and short winter days are the real constraints in London homes, and our selection reflects them. Phalaenopsis and Anthurium flower for weeks on a bright windowsill and tolerate warm, dry rooms better than most houseplants. Peace lily accepts the lower light of north facing rooms and hallways, though it flowers more freely in a brighter location. An indoor lemon tree or calamondin needs the sunniest position you have, ideally a conservatory or south facing bay. Our Kentish Town team can match each plant to your rooms.

Indoor Flowering Plants Popular Questions

What are the best flowering indoor plants in the UK?
For long flowering with little intervention, Phalaenopsis and Anthurium andraeanum lead: both typically hold their blooms for weeks and rebloom readily in a warm home. Peace lily flowers in less light than most. For scent and fruit as well as flowers, a calamondin or Meyer lemon gives the longest season of interest, often carrying blossom and fruit year round.
Can you grow a lemon tree indoors?
Yes, given the brightest position in the house, ideally full sun for six hours a day. An indoor lemon tree prefers a cool, bright room in winter to a warm living room, as heat with low light causes leaf drop and invites pests such as scale. Move it outside in the summer months and feed with a citrus fertiliser from spring to autumn.
Can you eat calamondin oranges?
Yes. Calamondin, a hybrid of mandarin orange and kumquat, bears small fruit with a sweet, edible rind and sharply sour flesh, used much like lime in marmalade, drinks and cooking. A calamondin orange tree will often produce scented flowers and ripe fruit at the same time, which makes it one of the more decorative orange trees to grow indoors.
