Indian summers can be brutal, with temperatures often soaring past 40°C and causing even hardy plants to wilt. For busy Indian gardeners—especially in hot, arid zones like Delhi, Rajasthan or Maharashtra—choosing drought-resistant, easy-care plants is key. These “tough” plants thrive on minimal water and care, keeping your garden green with little effort. Below are ten indoor and outdoor plants that stay happy in the heat, along with why they survive high temperatures and how to care for them.
Aloe vera is a hardy succulent that thrives in warm temperatures and requires little water. It stores moisture in its thick leaves, making it extremely drought-resistant. This plant prefers full sun or bright light, which makes it ideal for balconies or sunny windowsills. Its clear gel also soothes sunburn and skin irritation.
Light: 6–8 hours of bright sunlight.
Water: Deeply only once the soil is completely dry (roughly every 2–4 weeks). Avoid overwatering.
Soil: Well-draining sandy/cactus mix.
The snake plant (Sansevieria) is nearly indestructible. It can withstand high temperatures, low light, and irregular watering. This makes it perfect for both shaded rooms and sunny outdoor nooks. In summer, snake plants quietly clean indoor air, making them useful houseplants for health and decor.
Light: Tolerates anything from low light to bright indirect sun. Avoid scorching midday rays.
Water: Very sparingly – roughly once a month. Let soil dry out between waterings.
Soil: Poor-to-average, well-draining potting mix.
Marigolds are vibrant, sun-loving flowers that thrive on neglect. They happily tolerate heat and dry conditions, blooming all summer long with minimal attention. Planted in garden beds or pots, their bright blossoms add color and help repel pests.
Light: Full sun (4–6+ hours per day).
Water: Moderate – water when the topsoil dries (about 1–2 times per week in extreme heat). They withstand some drought.
Soil: Well-draining garden soil or potting mix. Feed lightly for continuous blooms.
Bougainvillea is a drought-tolerant flowering vine that thrives in direct, blazing sunlight. Its bright, paper-like bracts (often called flowers) bloom all summer with minimal water. This woody vine is ideal for walls, trellises or pergolas; it loves hot, dry conditions typical of western and central India.
Light: Full sun (6+ hours daily) for profuse flowering.
Water: Water deeply but infrequently. Once established, it needs only occasional watering (allow soil to dry between watering).
Soil: Slightly acidic, fast-draining soil. Prune after flowering to maintain shape.
Cacti are the ultimate low-maintenance plants, requiring very little water and thriving in hot, dry conditions. They come in many shapes and sizes – from globe and barrel cacti to small “cute” varieties – and are great for sunny balconies or indoors as decorative houseplants. Their succulent stems store water, so they sail through Indian summers easily.
Light: Bright, direct sun (morning sun and some afternoon shade if temperatures exceed 45°C).
Water: Once every 3–4 weeks in summer. Soil should be completely dry before watering again.
Soil: Specialized cactus/succulent potting mix for excellent drainage.
Lantana is a hardy flowering shrub that flourishes in full sun and needs little water. It produces clusters of brightly colored flowers that attract butterflies and bees. Lantana is very forgiving – it can tolerate poor soil and heat, making it popular in Indian gardens and balconies.
Light: Full sun (6+ hours).
Water: Drought-tolerant; water only when soil is dry. In summer, deep-water once a week or less.
Soil: Well-drained soil. Trim back leggy stems to encourage bushier growth.
Money plant (Pothos) is an easy-to-grow vine that thrives in warm weather with minimal watering. It can grow either in soil or even just water, making it very versatile. Indoors it cascades from hanging baskets or climbs walls, and outdoors it serves as a decorative groundcover or balcony plant. Money plant also purifies air and adds lush green decor.
Light: Bright, indirect light or partial sun. Tolerates low light indoors (growth slows).
Water: Water when topsoil is dry (about once a week). Avoid overwatering.
Soil: General-purpose potting mix. Provide a support or allow it to trail.
Haworthia, often called Zebra Plant (for its striped leaves), is a small, slow-growing succulent perfect for indoor gardens. It requires minimal watering and thrives in bright, indirect light. Its succulent leaves store water, so it easily survives apartment summers. Haworthia stays compact and is ideal for desks, shelves or small pots.
Light: Bright but indirect light (avoid harsh afternoon sun).
Water: Very sparingly – perhaps once a month. Let soil dry out completely between waterings.
Soil: Cactus or succulent mix. Avoid heavy soils.
Portulaca, also called Moss Rose, is a drought-tolerant, sun-loving annual that spreads as a groundcover. It produces colorful, delicate flowers throughout summer. Portulaca grows in poor soil and loves heat, so it’s perfect for rock gardens, borders or hanging baskets in blazing sun.
Light: Full sun (6+ hours daily).
Water: Very little – only during prolonged dry spells. It will survive on rain once established.
Soil: Sandy, well-drained soil. Poor soil is fine; avoid rich, water-retaining soil.
Basil (especially Indian holy basil or Tulsi) is a common summer herb. It needs minimal care and plenty of sunlight. With 4–6 hours of sun a day, basil grows rapidly, providing aromatic leaves for cooking and traditional use. Note that while basil loves sunshine, intense afternoon heat can scorch it, so a bit of shade in the hottest part of the day is helpful.
Light: 6–8 hours of sun (some afternoon shade recommended in very hot climates).
Water: Keep soil evenly moist (water 1–2 times a week in summer). Do not let it dry out completely.
Soil: Rich, well-drained soil or potting mix. Pinch off flower buds to encourage leaf growth.
You don’t have to abandon gardening when the mercury rises. By choosing tough, heat-tolerant plants and following smart care steps like morning watering and mulching, you can keep a green oasis even in India’s hottest months. These low-maintenance plants – from succulents to sun-loving flowers – will help your home or balcony stay lush through the summer.
Q: Which plants survive best in the extreme Indian summer?
A: Succulents and drought-resistant blooms top the list. For example, aloe vera is a hardy succulent that needs almost no water, and cacti likewise thrive with very little moisture. Heat-loving flowers like bougainvillea and lantana also flourish in full sun.
Q: How often should I water plants during summer heat?
A: Water deeply but infrequently. The best time is early morning to minimize evaporation. For most of the plants above, watering once or twice a week (with deep soaking) is enough. Succulents and cactus need even less — often only once a month.
Q: Can I keep these plants in direct sun all day?
A: Many on this list love full sun (e.g. bougainvillea, marigold, portulaca). However, even sun-lovers like basil (Tulsi) can get scorched by midday heat. It’s best to provide some afternoon shade or diffuse light during peak sun. In general, ensure potted plants can be moved to shade if leaves look stressed.
Q: Should I use mulch or fertilizer in summer?
A: Yes to mulch, but skip heavy fertiliser. Mulching retains soil moisture and keeps roots cool. Conversely, avoid fertilizing during heatwaves, as it forces plants to produce new growth that requires extra water.
Q: How can I tell if a plant is suffering from the heat?
A: Check for wilting, curling or browning leaves. These signs mean the plant is losing moisture faster than it can absorb. In that case, give it extra shade and water. Adjusting location or providing a temporary shade cover can save heat-stressed plants.
