HydrangeasThis article was prepared with the support of UFL flower delivery. We're usually told to protect houseplants from direct sun, and many of us have lost more than one plant on a scorching windowsill. But some plants languish without sun: they stretch, turn pale and refuse to flower. Here's which houseplants love the sun, how to recognise them and how to care for them on a south-facing window.
How to recognise a sun-loving plant
Sun lovers often give themselves away by their looks:
- thick, fleshy leaves and stems that store water for drought (cacti, aloe, jade plant);
- a waxy coating or fine hairs — the plant's own sunscreen (echeveria, panda plant);
- silver, grey or red leaves, bold variegation (croton);
- large bright flowers on plants from sunny regions (amaryllis, hibiscus, bougainvillea);
- origins in deserts, steppes or the Mediterranean — home of pelargoniums, oleander, rosemary and citrus.
Thin, large, soft leaves, by contrast, usually point to a forest plant that will burn in direct sun.
A sunny window: what goes where
15 houseplants that love the sun
| Plant | Notes |
|---|---|
| Cacti | Champion sun lovers. With bright light and a cool winter, many flower profusely. |
| Aloe | Tolerates direct sun; water sparingly, once the soil has dried out completely. |
| Jade plant (Crassula, money tree) | In sun the leaf edges turn red and the plant stays compact. |
| Echeveria, sedum, kalanchoe | Succulents that stretch and lose colour in shade. |
| Adenium | The "desert rose" flowers only with maximum sun and warmth. |
| Crown of thorns (Euphorbia milii) | A spiny shrub with bright bracts that flowers nearly all year. |
| Pelargonium (geranium) | On a sunny sill it flowers from spring to autumn. |
| Hibiscus (Chinese rose) | Loves bright light; shade it at midday in extreme heat. |
| Bougainvillea | Won't produce its bright bracts without direct sun. |
| Citrus (lemon, calamondin) | Needs lots of light and a cool winter. |
| Pomegranate | Dwarf forms flower all summer on a sunny window. |
| Bird of paradise | Needs bright sun and a cool winter to flower. |
| Croton (Codiaeum) | Its leaf colours are brighter in good light. |
| Oleander | A Mediterranean shrub; put it on the balcony in summer. Poisonous. |
| Rosemary and other herbs | A south window is your only chance to grow them indoors. |
The snake plant, weeping fig and spider plant also tolerate sun and are easy-going, though they're fine in part shade too. Indoor jasmine and Cattleya orchids love bright light but should be shaded from midday sun.
Caring for sun-loving plants
- Acclimatise gradually. After winter or a purchase, keep the plant in light shade for 1–2 weeks or its leaves will burn.
- Water by the soil, not the calendar. Soil dries faster on a south window, but succulents and cacti still need to dry out fully between waterings.
- Mist in the morning or evening, and only plants that like it (citrus, hibiscus). Never mist succulents.
- Watch for overheating. A pot on a hot sill cooks the roots — choose light-coloured pots or use a stand.
- Turn the pot a quarter turn every 1–2 weeks so the plant grows evenly.
- Add light in winter. A grow light helps sun lovers through short days.
Consider your own home
Choose plants for your real conditions. If trees or a neighbouring building shade your windows, even a south window may be only semi-shaded. On the upper floors of tower blocks, however, the sun can be so strong that it needs diffusing with sheer curtains, blinds or frosted film. Whitish or brown dry patches on leaves are sunburn — move the plant further from the glass.
FAQ
Which plants can go on a south window with no shading?
Cacti, aloe, jade plant, echeverias, adenium, crown of thorns and pelargoniums.
Why is my plant turning pale in the sun?
It may be sunburn or a lack of nutrients. Check the leaves aren't touching the glass and feed the plant.
Do cacti need shade in summer?
Mature cacti don't, but young or newly bought plants should be introduced to full sun gradually.
