Flower Power - Some of Best Flowering Hostas

When most gardeners think of hostas, they picture bold, architectural foliage: blues, greens, gold, variegation, and every texture in between. But while hostas are rightly famed for their leaves, they also offer surprisingly beautiful, long-lasting, and often fragrant flowers. Some varieties are grown almost primarily for their floral displays, bringing extra interest to shade gardens through summer. 

If you're looking to add real flower power to your garden, here are some of the best flowering hostas - plus tips to help maximise their bloom potential.

'Silly String' - Masses of Flowers on a Compact Plant

If you're after sheer quantity, Hosta 'Silly String' is hard to beat. This quirky, narrow-leafed variety may look delicate, but it produces an abundance of lavender-purple flowers that continue for weeks.

• Slender, string-like leaves add texture even when it's not in flower
• Ideal for containers or edging where the blooms can be admired up close

Gardeners who love a plant that earns its keep will appreciate how tireless 'Silly String' pushes out blooms.

'Shiny Sonata' - Big, Fragrant Flowers for Maximum Impact

While many hostas have lightly scented blooms, Hosta 'Shiny Sonata' is a true fragrance-forward variety. With its bold, glossy foliage and large, highly fragrant flowers, it delivers drama and scent in equal measure.

• Huge white blooms with a sweet perfume
• Great for planting near paths, patios, or seating areas

If you want a hosta that truly behaves like a flowering perennial, 'Shiny Sonata' is a top contender.

How to Improve Flowering in Hostas

to get the very best floral performance, focus on creating the right growing conditions. Here are practical tips to encourage bigger blooms, longer flowering periods, and healthier plants.

Tip 1 - Give Them Enough Light

While hostas are shade tolerant, those grown in dappled shade or morning sun typically produce more flowers.

• Too much deep shade = fewer scapes
• Avoid harsh afternoon sun, which can scorch leaves

Tip 2 - Improve Soil Quality

Hostas thrive in rich, moisture-retentive soil.

• Add compost or well-rotted manure every spring
• Mulch annually to maintain moisture and improve nutrients

Tip 3 - Water Deeply in Summer

A light watering will help hostas survive in Summer, a deep watering will help them thrive.

• Give them a good amount of water, go back 10mins later once soaked in and give more. This will help saturate the soil so it can retain moisture. 
• Only do this when it is hot and try as overwatering in periods when the soil is already retaining moisture can lead to root rot.
