1. Globe amaranth

The globe amaranth is “a lazy gardener’s dream”, according to Southern Living.

These round-shaped flowers, which can be spotted by their striking bright hues of magenta, purple, red and pink, do not require deadheading.

They are also heat and drought tolerant, meaning they grow well in full sun and can thrive even in poor soil.

2. Summer snapdragon

As their name suggests, these flowers are happy basking in the sun in hot weather conditions, where other plants would struggle.

Not only are they heat tolerant, they are also resistant to most pests and diseases.

Known for their tall flower heads that come in blue, pink and purple, this plant only requires occasional deadheading.

Though Summer snapdragons appreciate regular watering, they can handle dry spells well.

3. Blanket flowers

These blood-orange flowers, native to north and South America, are frequently found growing by beaches.

The vibrant, daisy-like plants are famously drought-resistant and sun-loving.

They are also easy to grow, requiring little or no fertiliser.

When caring for them, all they require is occasional watering and trimming of their old flower heads to allow new growth.

They are also not prone to pests and typically bloom continuously through the warmer months.

4. Dianthus

Each of these pink flowers, compact in size, has five petals with a frilled or pinked margin.

Their flower stems have a distinctive spicy fragrance which is said to recall clove and cinnamon.

This plant is also perennial, meaning it will come back every year.

Dianthus can thrive even in containers, requiring only minimal upkeep beyond the removal of spent blooms.
