Summer-flowering bulbs for August

We reveal six of our favourite August-flowering bulbs, including exotic choices for late-summer drama.

August often gets a bad rap as a month that’s lacking in interest, but of course there are plenty of August-flowering plants to grow, not least bulbs.

To accompany the blooms, don’t forget to grow a generous helping of foliage plants. Ornamental grasses like hakonechloa are easy to grow, as are ferns and hostas. For something more unusual, try Aralia cordata.

Discover some of the best summer-flowering bulbs for August, below.

Lush, colourful and dramatic – cannas are the perfect remedy for a fading later-summer garden.

Cyclamen hederifolium

Not to be confused with winter-flowering Cyclamen coum, C. hederifolium should just be beginning their late-summer and autumn display in August. Extremely hardy and shade-suited, they’re easy to grow in pots, or left to naturalise in the ground.

Eucomis

Eucomis are exotic bulbous perennials suitable for planting in pots and containers, or in the ground, in which case they may require lifting over winter. Good drainage is key, and full sun will encourage the best blooms.
