9 Ideal plants to grow in the summer

The summer in Brazil is synonymous with long days, intense sun and, in many regions, heavy rains and high humidity. For landscaping enthusiasts, this challenging season is, in fact, a golden opportunity to see the garden burst into color and texture. The key to success is choosing the right species: those that not only survive the heat, but actually thrive in the sun. Growing plants that love the heat and brightness of the Brazilian summer guarantees not only lush landscaping but also less work with replacements and substitutions. In this article, you will find a complete guide with the best options to fill your garden, balcony or flowerbed with the characteristic vitality of the hottest season of the year.

Making the most of the tropical summer

The Brazilian summer presents distinct characteristics that must be considered in landscaping. While in temperate regions the season is of moderate heat and constant growth, in Brazil, the period is marked by:

• Very high temperatures: Extreme heat demands plants with high thermal tolerance and that do not wilt easily.

• Intense solar radiation: The need for a lot of sunlight makes full-sun species mandatory.

• High humidity: The combination of heat and humidity (especially in coastal and forest regions) is perfect for the development of fungi and diseases in less adapted plants.

• Torrential rains: In many areas, summer rains are strong and quick, requiring soil with excellent drainage to prevent root rot.

Summer plants, therefore, are those that have been naturally selected to deal with this combination of sun, heat, and water. They are mostly species of tropical origin, native to Brazil or similar climates, which makes them robust and low-maintenance choices for this time.

Vibrant colors and abundant flowering in the sun

When thinking about summer landscaping, vibrant colors immediately come to mind. There are several species that stand out for their ability to produce spectacular flowers exactly when the sun is at its peak.

• Hibiscus: No summer plant list is complete without hibiscus. With its large, showy flowers (in shades of red, yellow, orange, pink, and white), it is a tropical shrub par excellence. It loves full sun and heat. To ensure continuous flowering, just keep regular watering (without over-saturating) and fertilize with potassium-rich fertilizer before the start of the season.

• Bougainville: It is the queen of heat and drought (although it appreciates watering in summer, its hardiness is remarkable). Bougainville is not afraid of the Brazilian sun; the more sun, the more it blooms. Its colorful "flowers" are actually bracts (modified leaves) that last a long time, covering walls and pergolas with a show of colors.

• Lantana: Ideal for flowerbeds, borders, and pots, lantana produces small flowers grouped in round clusters, in shades ranging from yellow to orange and red, often with different colors in the same cluster. It is extremely drought-resistant and heat-tolerant, and attracts butterflies, making it perfect for an ecological garden.

Ornamental foliage that stands out in this season

A summer garden is not only made of flowers. Many species with eye-catching foliage do very well in the heat, providing texture, volume, and a touch of visual freshness, especially in semi-shaded areas or near windows.

• Swiss Cheese Plant: Although it is often grown as an indoor plant, in tropical regions it can grow immensely in semi-shade, such as under the canopy of trees. Its large, lobed leaves bring an exotic and luxurious look, tolerating well the heat and elevated humidity of the summer, as long as protected from direct midday sun.

• Coleus or Broken-Heart: For those who want color without relying on flowers, coleus is unbeatable. Its leaves come in a myriad of patterns and colors, such as lime green, burgundy, hot pink, brown, and yellow. Although it prefers semi-shade, some varieties tolerate morning sun well. The important thing is to keep it always moist and fertilized to enhance the intensity of the colors.

• Caladium: Another plant whose leaves are the main attraction. Caladium has thin, heart-shaped leaves that look hand-painted with splashes of white, pink, or red. It is a plant that likes humid and warm projects, ideal for winter gardens or the shadier corners of the garden during the tropical summer.

Aromatic plants that love summer

Summer is also the season of harvest and accelerated growth of many herbs and vegetables that demand lots of sun and heat. Growing these species not only beautifies but also makes landscaping useful.

• Basil: This herb is essential for Mediterranean and Brazilian cuisine and requires a lot of sun to grow strong and develop its characteristic aroma. Summer is the ideal time to plant it in pots or flowerbeds. The rule is simple: the more sun and heat, the more you should water it, but make sure the soil drains well.

• Peppers: The growth and fruiting cycle of pepper plants is intensified by heat. They are full-sun plants that appreciate warm and humid weather. In addition to producing edible fruits, pepper plants of various colors and shapes (red, yellow, purple) are extremely ornamental in pots or flowerbeds.

• Lemongrass: Perfect for live fences or as a standalone plant in large pots. Lemongrass loves full sun and grows quickly in summer, providing aromatic leaves for teas and natural insect repellent.

Essential maintenance tips

Although summer plants are hardy, proper maintenance during the hottest months is crucial to ensure they reach their maximum potential.

• Smart Watering: Heat increases evaporation, requiring more water. However, the most common mistake is shallow and frequent watering. Water deeply and in the morning or late afternoon. Avoid wetting the leaves in the evening, which can encourage fungi due to high nighttime humidity.

• Nutrient Reinforcement: The accelerated summer growth demands nutrients. Use balanced slow-release fertilizers (like NPK 10-10-10) or organic ones (worm humus, compost) every 30-45 days. Flowering plants benefit from fertilizer with more phosphorus and potassium.

• Cleaning and Stimulating Pruning: Remove wilted flowers ("deadheading" or pinching) and dry branches. This not only improves the appearance of the plant but also redirects energy toward the production of new flowers and shoots, prolonging the flowering period.

By choosing the right species and following these maintenance tips, your summer garden will transform into a spectacle of colors and life, bravely resisting the Brazilian sun and celebrating the liveliest season of the year.
