These are the lifesavers for your garden—plants that give bright, colorful blooms even when temperatures soar.
In this detailed guide (Part–I of the series), we will explore the 5 best flowering plants for the summer season, perfect for Indian and tropical climates. If you want a beautiful, low-maintenance, and bloom-filled garden during hot months, these five blooms are must-haves!
1. Bougainvillea – The Queen of Summer Gardens
Bougainvillea is hands down the most popular summer flowering shrub. Its papery bracts in bright pinks, reds, whites, oranges, and purples can instantly make any space look vibrant.
Why It Thrives in Summer
Bougainvillea loves full sunlight, dry weather, and minimal water. The hotter it gets, the better it blooms.
Care Tips
- Sunlight: 6–8 hours of direct sun.
- Soil: Well-draining sandy or gritty mix.
- Water: Only when the soil is fully dry.
- Fertilizer: High-phosphorus fertilizer once a month.
- Pruning: Light pruning after every flush enhances more blooms.
Blooming Season
Peak bloom: February–September, with heavy flowering in hottest months.
Bougainvillea is perfect for walls, fences, terraces, and large pots.
2. Portulaca (Moss Rose) – The Cutest Sun-Loving Groundcover
Portulaca, also called Moss Rose or Sun Rose, is one of the most heat-loving and drought-tolerant flowering plants. Their tiny, bright, cheerful flowers open in sunlight and come in multiple shades.
Why It Thrives in Summer
Portulaca stores water in its leaves, allowing it to withstand extreme heat.
Care Tips
- Sunlight: Minimum 6 hours direct sun.
- Soil: Sandy or porous soil; avoid heavy watering.
- Water: Very low—overwatering kills the plant.
- Fertilizer: Not compulsory, but a mild fertilizer once in 30 days helps.
Blooming Season
Flowers daily through the summer—March to October.
Portulaca is great for borders, hanging pots, and balcony railings.
3. Hibiscus – The Tropical Beauty That Loves Heat
Hibiscus (Gudhal) is a classic Indian summer flowering plant. The large, showy flowers in red, yellow, pink, orange, and white look stunning and bring a tropical feel to any garden.
Why It Thrives in Summer
Hibiscus enjoys warm, sunny weather and grows more vigorously in the heat.
Care Tips
- Sunlight: 4–6 hours of direct light.
- Soil: Loose, fertile soil rich in organic matter.
- Water: Frequent watering in summer; don’t let soil dry out completely.
- Fertilizer: Heavy feeders—use NPK 19:19:19, seaweed liquid, or cow dung every 15 days.
Blooming Season
Year-round in tropical climates; peak blooms in summer.
Hibiscus grows well in pots, terraces, and garden beds.
4. Vinca / Periwinkle (Sadabahar) – The Easiest Summer Flower
Vinca or Periwinkle is the most low-maintenance summer flowering plant. It blooms continuously even in the hottest months when other plants struggle to survive.
Why It Thrives in Summer
It tolerates heat, drought, poor soil, and still blooms fully.
Care Tips
- Sunlight: 3–5 hours of good sunlight.
- Soil: Draining soil; avoid heavy clay soil.
- Water: Very little—water only when soil is dry.
- Fertilizer: A mild liquid feed every 20 days is enough.
Blooming Season
Blooms all 12 months in tropical climates.
Perfect for beginners—once planted, it takes care of itself!

Sunflowers thrive in the harsh summer sun and brighten your garden with their cheerful yellow heads. Kids love them, and they attract beneficial pollinators.
