Petunias, Lantana and Verbena ideal for scorching balcony gardens

Petunias are highlighted as the top choice for sunny terraces and hanging baskets, thriving in direct sun and requiring regular watering, especially in containers, and benefit from the removal of spent flowers to promote continuous blooming.

Pelargonium (geranium) and lantana are also recommended for hot balconies; pelargonium tolerates high temperatures and comes in upright and trailing varieties, while lantana endures intense sun and short dry periods with minimal water needs.

Verbena and large‑leaf succulents such as the “big‑flowered stonecrop” are praised for their ability to flower throughout the summer and store water, making them suitable for exposed spots. Experts advise watering early in the morning or evening, using well‑draining soil, and ensuring adequate drainage to keep plants healthy during extreme heat.
