If you are looking for the largest hostas for your garden, you are in the right place. Giant hostas are among the most sought-after shade perennials. At maturity, they can form clumps more than 2 metres across, with leaves that resemble huge plates.

In this article, we look at which hostas grow to the largest size, why they are so popular, and which cultivars, based on our many years of experience at Eurohosta, belong among the true giants.

Why are giant hostas so popular?

Large hostas can create an effect in the garden that is difficult to replace with other plants.

Their main advantages are:

• they create a monumental garden look,
• they look luxurious and exotic,
• they are long-lived and become more impressive every year,
• they require minimal care,
• they grow excellently in shade and partial shade,
• they are attractive from spring until autumn.

It is no coincidence that large hostas are among the most desirable plants in modern gardens.

Not every hosta will become giant in every garden

The size of a hosta is not determined by the cultivar’s genetics alone. Genetics define the potential, but whether the plant reaches it depends on growing conditions. That is why the same hosta can be enormous in one garden and only half the size in another.

Soil quality and depth

Hostas develop a strong root system. In deep, humus-rich, fertile soil they can take up more water and nutrients, resulting in larger leaves and a greater overall clump size. In poor or stony soil, they remain considerably smaller.

Plenty of water

Hostas are plants with a high demand for water. Large cultivars can transpire several litres of water per day during summer. If a plant suffers from drought, it produces smaller leaves and growth slows down. Consistent moisture throughout the season is one of the main factors influencing hosta size. 

Competition from tree roots

This is one of the most common reasons for disappointment among growers. A hosta planted under a birch, spruce or maple has to compete for water and nutrients with thousands of tree roots. Even a giant variety may then remain surprisingly small.

Amount of light

Most hostas thrive in partial shade. Very deep shade often leads to slower growth. By contrast, gentle morning or evening sun encourages the formation of larger clumps. The exceptions are some blue hostas, which lose their waxy bloom in strong sun.

Age of the plant

Many hostas reach their true size only after 8 to 10 years. A young plant bought from a nursery often looks modest, but after several years it can become a huge clump.

Regular division

If you divide a hosta frequently, you keep returning it to a “young age”. The plant then invests energy in rebuilding its roots rather than increasing the size of the clump. The largest specimens are usually those that have not been transplanted for decades.

Fertilising

A good supply of nutrients supports the production of large leaves. The best results come from adding compost or well-rotted organic matter every year. Excessive nitrogen fertilisation, however, can cause soft tissues and greater susceptibility to damage.

Climate

Hostas originate from regions with ample rainfall and moderate summer temperatures. In cooler and moister regions, they often grow larger than in hot, dry areas.

An interesting paradox

Many growers believe that hostas need deep shade. In reality, the largest specimens often grow in places with morning sun, rich soil and plenty of water. It is precisely the combination of light, moisture and nutrients that allows the plant to use its genetic potential fully.

For example, Hosta 'Empress Wu' may reach 120 cm across in one garden and more than 250 cm in another. The difference is not in the variety, but in the conditions provided by the grower.

The largest hostas in the world according to expert sources

Among the cultivars most often listed in international rankings of the largest hostas are:

1. Hosta 'Empress Wu'
2. Hosta 'Jurassic Park'
3. Hosta 'Sum and Substance'
4. Hosta 'Blue Angel'

6. Hosta 'Earth Angel'
7. Hosta 'Sagae'
8. Hosta 'Komodo Dragon'
9. Hosta 'Victory'
10. Hosta 'Niagara Falls'

These varieties are widely known for their ability to form massive clumps, often over 80 cm tall and more than 2 metres wide.

Hosta 'Sum and Substance' is an older variety with excellent growth potential

Hosta Giantland Megalodon came to Europe from the USA. 

Hosta 'Green Acres' with green, arching leaves never disappoints. Beautiful near a water feature!

This giant has upright growth and unstoppable vigour – hosta Holar Arches Park.

10 largest hostas according to our experience at Eurohosta

Over the years, we have grown thousands of hosta cultivars and regularly observe their growth in different conditions. Some varieties genuinely surprise us with their impressive size. We agree with the selection often presented by international magazines and experts (see the ranking above), but we also have our own favourites.

Here is our ranking of hostas that are among the largest in our growing conditions:

1. Hosta 'Empress Wu'
   A legend among giant hostas. Huge leaves, a massive habit and a dominant presence. This hosta forms majestic clumps that become a natural focal point in any shade garden. In ideal conditions, it belongs among the largest hostas grown in the world. 
2. Hosta 'Sum and Substance'
   One of the best-known large hostas in the world. In ideal conditions, it produces enormous golden-green leaves. It stands out for its fast growth and its ability to form massive clumps at a relatively young age. It is rightly considered one of the most important hostas in the history of breeding.
3. Hosta 'Lakeside Maverick'
   A strong-growing variety with exceptional potential to reach truly monumental dimensions. Large, green, wavy leaves form a dense and elegant clump that attracts attention from a distance. In favourable conditions, it is among the most impressive hostas for large gardens.
4. Hosta 'Blue Angel'
   The largest blue hosta commonly grown in gardens. Older plants are literally majestic. Huge blue-green leaves create a calm and harmonious effect, especially in partial shade. Many growers consider it the most beautiful large blue hosta of all.
5. Hosta 'Green Acres'
   A reliable giant with strong growth and excellent vitality. It produces large green leaves and is regularly among the biggest plants in collections of experienced growers. It is known for its longevity and easy-care nature.
6. Hosta 'Broad Band'
   A surprisingly powerful hosta that forms large, dense clumps when grown well. Its broad leaves with contrasting colour add an elegant look to the garden. As the years pass, it gains volume and becomes a striking focal point in the border. 
7. Hosta 'Enchained Melody'
   An elegant cultivar with great growth potential and a strong garden presence. Rich foliage forms a harmonious, well-balanced clump. This is a hosta that combines size with exceptional elegance.
8. Hosta 'Giantland Big Bastard'
   The name itself suggests that this is a hosta for lovers of true giants. This variety was bred with an emphasis on extreme size and powerful growth. At maturity, it can form a clump that commands respect even among experienced hosta collectors.
9. Hosta 'Holar Arches Park'
   A massive hosta with excellent growth ability and a talent for forming large clumps. It stands out for its strong vitality and reliable performance even in less than ideal conditions. Given enough space, it can reach truly impressive proportions.
10. Hosta 'Giantland Megalodon'
    One of the newer giant hostas bred with the aim of achieving extreme size. The name “Megalodon” itself refers to the huge prehistoric shark, which makes it clear that this cultivar is intended for lovers of truly large hostas.

How to grow a giant hosta? 3 proven tips

Give it plenty of space

Large hostas do not like competition. If you want them to reach maximum size, give them enough room.

Feed regularly with compost

The largest hostas grow in soils rich in humus. An annual layer of quality compost can significantly boost their growth.

Never let them dry out

Hostas produce an enormous amount of leaf mass. Without enough water throughout the season, they cannot make full use of their genetic potential.

Hosta Valley's Salty Crocodile is one of the lesser-known giants. 

Conclusion: Which hosta is the largest?

If we had to choose a single king among hostas, it would probably still be Hosta 'Empress Wu'. Nevertheless, there are several cultivars that, under certain conditions, can match or even surpass it in size. Our experience shows that varieties such as Hosta 'Lakeside Maverick', Hosta 'Blue Angel' and Hosta 'Giantland Big Bastard' can, after years of cultivation, reach truly impressive dimensions.

If you dream of a garden with a monumental look, giant hostas are among the best investments. All they need is time, quality soil and enough water. In a few years, they will become the focal point of your garden and will be admired by every visitor.
