These undemanding plants require minimal care to look their best. For low-maintenance shade garden beauty, it's tough to beat hostas.

Like Ireland, where the landscape is said to grow in “forty shades of green,” hostas come in many different colors of green, too, from emerald to chartreuse, blue-green to avocado, and artichoke to olive. Not all hostas are green, though. Some lean toward butter-yellow or gold, powder blue, cream or white. Others are variegated or bordered or striped in various hues.

Leaf textures, shapes and sizes also vary from plant to plant, making it possible — and fun — to collect dozens of different species or selections. Look for leaf surfaces that are crinkled, smooth, wavy, puckered or concave.

The leaves themselves can be heart-shaped or elongated, oval or rounded. In general, hosta leaves grow symmetrically, forming mounds of foliage that can range from just 3 inches high, for dwarf varieties, to 5 feet tall, for giant types.

Plant type: Herbaceous perennial
Hardiness: USDA Zones 3 to 9
Size: Plant range in size from about 2 inches to 60 inches tall and about as wide, depending on selection.
Culture: Prefers partial to full shade; sun-tolerant cultivars are available.

How to Grow Hostas

Hostas originally come from China, Japan and the islands of South Korea. These outstanding foliage plants grow best in rich, well-drained soils.

Most hostas need shade, but some will take sun, so read plant labels and choose varieties that like the growing conditions you can offer. In general, blue hostas have richer color in shady spots, while gold ones need more sun to show their brightest hues.

The majority of these undemanding plants grow in average soils and are hardy in Zones 3 to 9. Hostas need average water, but most benefit from watering during dry spells. Also water more often if they’re planted underneath trees that may compete for water and nutrients.

Be careful not to overwater, which can cause the plants to rot. Suspect crown rot if you see yellow foliage and stunted growth.

How to Plant Hostas

Spring is the best time to plant, transplant and divide hostas, when leaves are begining to emerge.

To plant, dig a hole as deep as the root ball and at least twice as wide as the diameter. Space your hostas out as required by their spread at maturity. You won't go wrong adding organic matter to planting holes for hostas. Work in composted leaves, composted manure or whatever type of local compost you can get your hands on. Compost helps improve soil nutrition and moisture in a way that hostas love.

Add some mulch to help hold moisture in the soil and keep down weeds; once hostas become established, they usually crowd out competing grass and weeds.

Transplanting & Dividing

Hostas are easy to transplant either from divisions or directly from nursery pots (see full directions here). To dig a hosta for transplanting, if you're working in early spring, simply dig as much of the rootball as possible. Splitting hostas is best done in spring or early fall. Ideally, plan on dividing hostas before spring or fall rains arrive.

Hostas don’t typically need dividing unless they have outgrown a space. In most cases, even when a hosta has filled it growing area, the resulting root restriction doesn’t damage the plant but simply reduces the growth rate.

Growing Hostas in Pots

Many hostas are great container plants. For best results, use a pot with drainage holes, or drill some in the bottom. Fill the pot with potting soil mixed with slow-release fertilizer.

Take your hosta out of the nursery pot and gently loosen the root ball. Put it in its new container and add some soil, burying it no deeper than it was in its original pot. Water thoroughly and make sure any excess drains away.

Container-grown plants often dry out faster than those in the garden, so water again as needed, especially in hot weather.

Using Hostas in Your Garden

During the course of the growing season, expect to see flower stems appear on your hostas. These stems support a spike of white to lavender blooms. The flowers beckon bees, butterflies and hummingbirds to the garden. The long stems look beautiful added to garden bouquets.

Use hostas along a border or as a specimen plant in a shade or woodland garden. You can combine with other shade-loving plants, such as ferns, bleeding heart or epimedium, or use it as an accent by itself.

If you're primarily growing your hostas for the leaf color they bring to the landscape, you might want to clip flower stems as they form. This creates a consistent look in your hosta plants, although the blue leaf types typically produce another flowering stalk if deadheaded.

Care for Hostas

As much as gardeners like hostas for their steady, reliable beauty, deer like them for their tasty foliage. Rabbits also find hosta leaves, especially the new shoots, particularly irresistible. There are a host of techniques for keeping critters away from hostas — everything from using fabric softener in a spray bottle, to home brews featuring garlic and capsaicin, to rotten egg sprays.

What works for one gardener may not work for your backyard's herd of deer, although most folks report consistent success with dried blood repellents and plastic bird netting tossed loosely over plants.

Slugs and snails also wreak havoc on hostas, and there are plenty of tips for dealing with these pests as well. Try pet-safe slug baits, pine straw mulch and various traps to keep slugs and snails in check. It's also worthwhile to learn when these slimy munchers reproduce. For many snails and slugs, fall is egg-laying time. Eggs hatch and young slugs go into winter hiding. In spring, they appear early and have voracious appetites. Continue to treat for slugs in fall to put a dent in populations.

Few diseases bother hostas, although anthracnose can show up in warm, humid weather. You’ll recognize it by the big, irregular spots with dark borders that form on the leaves; later, the middle of the leaves may look torn. Try to avoid the problem by spacing your plants as recommended and watering with soaker hoses or drip irrigation rather than sprinkling the foliage from overhead. If you use a fungicide, choose one that targets this disease and follow label directions.

Hosta Varieties

This incredible group of perennials features more than 8,000 named cultivars. There's definitely a type of hosta to please every single gardener.

Hosta varieties cover the gamut in terms of size. Tiny miniature types grow 2 inches tall and 4 to 6 inches wide, and gargantuan hosta varieties reach a mature size of 48 inches across and 60 inches tall.

Small hosta varieties offer an ideal size for planting along walkways, in shady rock gardens or in fairy gardens. To keep small plants from disappearing among full-size counterparts, many gardeners tuck miniature types of hostas into containers. This technique works especially well in mild-winter regions where temperatures aren't cold enough to damage the plants.

Miniature Hostas

The names of miniature hostas usually contain clues that the plants are small, such as 'Baby Booties' (5 inches tall, 19 inches wide), 'Bitsy Gold' (8 inches tall, 21 inches wide) or 'Blue Mouse Ears' (8 inches tall, 12 inches wide). Most nurseries that specialize in selling many hosta varieties usually have lists of miniature types.

Giant Hostas

Giant hostas also frequently have names that contain clues to the plant's size. A few larger-than-life hostas include 'Bigga Luigi' (25 inches tall, 80 inches wide), 'Big Daddy' (25 inches tall, 66 inches wide), 'Kingsize' (48 inches tall, 84 inches wide) and 'Frost Giant' (28 inches tall, 72 inches wide). One of the most well-known giant hostas is 'Empress Wu', which grows to a hefty 48 inches tall and 60 to 72 inches wide, with individual leaves up to 18 inches across.

Giant hosta varieties can hold their own anywhere in a landscape, but look especially lovely planted beneath mature trees, atop retaining walls or as part of a hosta garden that fills a shady area. Pair large hosta varieties with shrubs and small trees to create plant combinations that are to scale. Or achieve the same effect by planting large and medium hostas side by side. Just be sure to space plants properly to avoid having the large one engulf the smaller.

Slug-Resistant Hostas

Slug-resistant types of hostas make it possible to grow these leafy perennials with less slug and snail damage. The slug-resistant hostas typically offer leaves that are thicker, blue or have a seersucker texture. The names of classic slug-resistant hostas, like 'Sum and Substance', 'One Man's Treasure' and 'Praying Hands', don't give a clue about their non-appeal to slugs. Others, like 'Alligator Shoes', 'Rhino Hide' and 'Bulletproof', offer names that are more forthcoming in terms of slug resistance.

Other hosta varieties offer outstanding leaf color in shades of blue, gold, chartreuse and variegated patterns. There's even a white leaf hosta, 'White Feather'. It's worth a visit to a garden center or nursery that specializes in hostas if you're considering filling a shady area of your yard with these leafy wonders. You'll discover the vast array of hosta varieties available, including ones that open fragrant flowers.

Hostas for Sun

Ideal growing conditions for hostas feature filtered light, or what a plant tag would label "partial shade." But many hostas can adapt to increasing amounts of sun.

Hosta plants that tolerate sun generally have thicker leaves. 'Rhino Hide' hosta, 'Thunderbolt' hosta and 'Liberty' hosta are varieties with thick leaves. The thicker leaves, by the way, also offer greater slug resistance.

Hostas that open fragrant flowers can usually withstand a little more sun. These types of hostas include 'Fried Bananas' hosta, 'Garden Delight' hosta and Hosta plantaginea, a native of China with flowers that open and release fragrance at night. Also, hostas that can withstand some sun typically have leaves with hues of white, yellow or gold. The leaves may be solid or have some variegated pattern of these colors. 'Fire and Ice' hosta has bright white leaves with green edges. 'Sun Power' hosta has bright chartreuse leaves that glow in the landscape. 'Sum and Substance' hosta also has chartreuse leaves, which are large (up to 20 inches across) and puckered.
