The hosta is the chameleon of the plant world, for it can produce foliage in shades of butter-yellow, gun-metal grey, almost-blue, clotted cream and green in its many guises. Leaves can be finely margined, or bear broad brush strokes of vibrant colour, or have a subtle overwash that adds a luminous sheen. Foliage can be smoothly varnished, or as richly textured as the thickest cotton quilt, or have a dull patina worthy of the finest antique, or pucker up like a taffeta skirt.

Some hostas are positively statuesque and make a huge statement like an elegant swirl of silk. Others are quiet enough to mingle with the humble fern and some are so tiny they fill the smallest gap. It’s this diversity of form and colour that makes them such popular plants for shadier places especially in the USA, where gardeners have to contend with bitterly cold winters and hot summers.

Japan is the heartland of the wild hosta, with three-quarters of the 40-odd wild species found there. Natural hybrids occurred widely in woodland populations there and were eventually moved into gardens. As a result the hybrids and species became muddled. Further confusion has arisen because natural mutations, or sports, have also occurred. A green-leaved form, for instance, might throw up a variegated section one year and then produce a completely different variation the next. In more recent times micropropagation has produced variations as well, and now there are 8,000 named cultivars of this very hardy perennial with more popping up every year. With all this choice it’s imperative to pick the very best: the ones that become superstars.

The history of the hosta

Hostas were first recorded by Engelbert Kaempfer (1651–1716) who was stationed on a tiny Japanese island while working for the Dutch East India Company. He made drawings and sent them back to the Netherlands, but couldn’t send any plant material because it was forbidden.

However, the hosta was named after an Austrian botanist called Nicolaus Thomas Host (1771–1834) in 1812. Five years later the plant was also named Funkia after Heinrich Christian Funck (1771–1839), a Bavarian who collected Alpine ferns. The name Hosta, which was coined before Funkia, became the valid name.

The Japanese call the hosta the giboshi because the rounded shape of the leaves resembles an ornamental cap, rather like a door knob, widely used on the posts of temples and bridges. The young leaves were traditionally eaten in spring, but the familiar woodlander wasn’t highly regarded in Japan as an ornamental plant until recent times.

The first hostas to arrive in Europe (Hosta plantaginea and Hosta ventricosa) came from China (not Japan) in the mid 1700s. Almost a century later Philipp Franz von Siebold (1796–1866) and Scottish botanist Robert Fortune (1812–1880) sent back specimens of Hosta sieboldiana and Hosta fortunei.

Where to plant hostas

The key to using hostas well is to space them far enough apart to display their graceful form, rather than packing them cheek by jowl. This will allow them more space as they mature and allow you to tackle any slug problems.

Choose the right sized hosta for your gap and then consider foliage. Too much mixed variegation will jar the eye, so use brighter gold and green forms to lighten up shade, alongside green forms. Cream and white are subtler in colouring and mix well with blue-grey hosta foliage, but can clash with rich greens.

Hostas adore summer rainfall, which encourages more sumptuous foliage, but they also need prolonged cold weather to encourage a necessary period of dormancy. Their roots are extremely hardy, but resent being too wet in winter, so ensure that they have good drainage.

Caring for hostas

Top dress with well-rotted manure or garden compost twice a year. Apply just as the plants enter dormancy in the autumn and then again in spring, just as the shoots begin to appear.

When to divide hostas

Divide congested plants in spring, just as the shoots are emerging.

When do hostas come up?

Hostas die back completely in winter, and reshoot again in early spring.

When to plant hostas

Plant hostas in spring or autumn, when the soil is moist and warm. Avoid planting in high summer, when it is often hot and the soil is dry.

How to water hostas

When I visit Japan, as I do most years, I find many hostas bred in America and Europe on their garden centre benches and they love the warm, Asian rainy season, which lasts for about six weeks. Bursts of torrential rain are interrupted by hot sunshine, producing lavish foliage that catches every raindrop. Try to emulate these damp conditions by watering copiously in May and June.

Protecting hostas from slugs

Hostas are extremely long-lived and very hardy, but tend to be slug-prone. Slugs only begin to feed at dusk and do most damage when the young leaves are emerging, so this is the time to be vigilant. Here are some ideas for minimising slug damage:

  • Frisk your plants regularly at dusk and destroy any slugs attacking your leaves.
  • Lay small plant pots on their sides to collect snails.
  • Water on slug nematodes in April to keep slug numbers down. Choose a damp evening when the weather is warm.
  • Disturb the soil by hoeing with a small onion hoe, getting right between the plants. This will bring slug eggs to the soil surface where they will either be eaten, or dehydrate.
  • Collect up wilted foliage so that slugs and snails cannot hide in the autumn.
  • If growing hostas in pots, avoid any with overturned lips because slugs and snails hide underneath. Use straight-sided pots and get them off the ground, using feet. Rub petroleum jelly around the rims to discourage them further.
