Calla Lilies (Zantedeschia spp.), With their spectacular cup-shaped flowers, are used in many summer gardens. Their lighting requirements are not specified, they can be planted both in the sun and in the shade. Winter hardy to U. S. Department of Agriculture plant hardiness zones 9 and 10, they can be grown either outdoors or in containers.


The most famous calla is the white calla (Zantedeschia aethiopica), considered a weed in Africa but widely grown in American gardens for its white flower. Hybrid types (Zantedeschia hybrida) often have colorful flowers instead of white and come in shades ranging from yellow, pink and cream to dramatic shades of red and purple. Other species, such as Zantedeschia ailanthoides, offer varieties such as the two meter high “pink persuasion”. Calla lilies bloom on bare stems that rise above stemless leaves that grow from underground rhizomes.

Light requirements

Calla lilies prefer full sun or partial shade, although their flowers will look less impressive in shady conditions. In areas where summers are long and hot, calla lilies often do best in partially shaded areas where they can take a break from the afternoon sun. In colder environments, they tolerate full sunlight well. They can also be grown in containers and overwintered outside the hardiness zone, provided they are placed in a bright, sunny window in the colder months.


Callas are very moisture tolerant and can be grown in moist soil or even under a foot of water at the edge of a pond or stream. Outside of the hardiness zone, rhizomes should be dug up and stored until planted again in spring. White calla lily is the most hardy of calla lilies and is winter hardy in USDA zones 8 through 10. They are susceptible to both soft rot, especially in poorly drained environments, and aphids, especially when grown indoors. Propagates by dividing rhizomes or planting seeds.

Application in the garden

The calla lilies are commonly used in flowerbeds or depressions on the mainland, or grown in baskets or in the mud at the edges of ponds or in water systems. They can also be grown as potted plants or in containers moved from outside in the colder months. Callas contain mild skin irritation, and contact with the juice can cause a reaction.

How to grow calla lilies

Introduction: Calla lily flowers, also called trumpet lilies or lily of the Nile, most often have waxy white flowers that twist and curl gracefully, ending in a delicate spot. Calla flowers can also be pink, orange, or red, and the heart-shaped dark green leaves can also be varied with white flecks. Installations lilii Calla pochodzą z bagien Republiki Południowej Afryki, ale zyskały popularność w ogrodach w Stanach Zjednoczonych jako rośliny marginalne w stawach i rośliny doniczkowe. È un fiore popolare per i matrimoni e la Pasqua, e i fiori di calla tagliati resistono a lungo nelle esposizioni floreali. Calla lily grows up to 2 feet tall and can be grown in containers for plants and miniature lily varieties that you can store.

Scientific name: Zantedeschia aethiopica

Plant type:Perennial herbaceous flower

Light:Calla lily flower requires partial shade (full sun in cooler climates).

Waterfall: Keep the calla flower soil moist (but not too wet as the plant bulb can rot). Dark leaf tips may mean you are overwatering (see “Tips for Watering Installations” for more information). Once the calla has blossomed and begins to die, stop watering so the bulb can dry out and be stored until the next growing season.

Fertilizer: Fertilize Calla Lily with onion fertilizer every month. Stop fertilizing after the calla has flowered. If the leaves have dark tips, you can add too much fertilizer.

Temperature:If you live in cooler climates like the Pacific Northwest, you can thriveZantedeschia aethiopica ‘Crowborough,’ which can tolerate cooler (but not cold) temperatures in outside balcony container gardens. In cold climates, overwinter the calla indoors so that it blooms all year round. If you don’t have room inside, take out the bulbs when the plant dies and save them for the next growing season.

Pests and diseases: Kill any small pests on the calla lily with insecticidal soap or plant-safe spray. Calla lily flower is prone to several diseases such as rhizome rot, bacterial rot, gray mold and some viruses.

Propagation: Grow a calla from bulbs. She digs the bulbs out of the ground after the plant dies in the fall (divide the onion to get more plants). Plant the dried calla bulbs 3 inches deep with the leaves facing up. After planting, the calla will flower in about three months. You can also propagate callas by growing them from seeds.

Various informations: Provide the best care for your calla lily by keeping it in well-draining, loose potting soil, and add coffee grounds to the calla lily’s plant container to make the soil more acidic. Although this houseplant can live in a suitable climate all year round, let it die for about two months of the year. This will allow your calla flower to rest and return with better flowering in the next growing season (it may not even bloom in the first year). During the rest period, you can dig up and store the tubers or keep them in dry potting soil.

The calla takes its name from an ancient scientific name. This flower was once classified in Callagenus, but this genus has been divided, and now the calla flower is presentZantedeschiagender.

When planting calla lilies (Zantedeschia aethiopica), choosing the right depth is an important first step in creating a healthy plant. These perennial herbaceous plants produce tuberous roots of the rhizome. Large white flowers bloom on fleshy green stalks in summer. Calle grow in U. S. Department of Agriculture plant hardiness zones 8 through 10. Plant calla lilies in a moist garden bed or grow this water-loving plant in ponds and stream beds.

The depth of planting the garden

You may have found your calla lilies for sale in a garden center or online, often as dormant rhizomes that look like bulbs. Plant calla rhizomes 4 to 6 inches deep in spring in full sun or partially shaded flower beds. Larger rhizomes should be planted deep enough that the tip of the rhizome is 2 inches below the soil surface.

Calla roots have growth points from which new shoots grow. When planting, arrange the rhizome horizontally in the hole. Make sure the long feeder roots are at the bottom of the pit and the growth points are at the top.

Plant depth in the pond

To plant calla lilies in water, dig a hole in the mud and place the rhizomes in the mud with the growth tips facing up. Callas can be planted in water up to 12 inches deep. As an alternative method of pond planting, grow calla lilies in heavy containers and soak them in water at the edge of a pond or stream. This makes it easier to reposition the plants and, in cold climates, to harvest and store them for the winter in a shed or garage, where temperatures remain above freezing.

Potted Calle

Calla lilies make good indoor or outdoor houseplants, as long as they’re completely moist, says White Flower Farm. Use quality potting soil and soak it well before planting. The potting mix should be slightly muddy. Use the same planting depth, 4 to 6 inches, as when planting in the garden.

Calla lily care w pomieszczeniach jest podobna do pielęgnacji na zewnątrz. Indoor or outdoor containers dry out much faster than garden soil, so check soil moisture frequently in hot, sunny weather. Pots made of plastic, metal, or glazed clay retain moisture better than vases made of porous materials such as wood or unglazed clay.

Keep calla lilies out of the reach of children and pets. The plant contains insoluble calcium oxalates which, according to the ASPCA, cause intense burning, swelling, difficulty in swallowing and vomiting when chewing or eating.

Calla Lily Intervals and Care

To create full, lush calla lilies without overcrowding the plants, place them 12-18 inches apart in flower beds, ponds, and flower pots. Calla lilies grow in full sun to part in the shade and require consistently moist or wet soil. This plant is ideal for wet areas where other plants tend to rot.

In frost-prone areas, buds die off in winter and grow back in spring. Cover the calla bed with a thick layer of loose mulch to protect the rhizomes from frost. When growing calla lilies in climates below zone 8, dig the rhizomes and store them for the winter in moist peat, or plant them in pots and place them in a sunny window, according to the Missouri Botanical Garden. In a frost-free climate, calla lilies grow outdoors all year round.

Calla lily grows from a type of bulb called a rhizome and produces very large green leaves, usually covered with lighter spots. The flower blooms from the apex of a rather thick stem and resembles a rolled-up paper in the shape of a trumpet. The calla belongs to the same family as the caladium and the jack-in-the-pulpit. Although called a lily, this plant isn’t quite a lily. Calla lilies are fairly easy to grow and are a flashy addition to your home or garden. They are also a very popular choice for bridal bouquets and cut flower arrangements. Calla lily is a very hardy and powerful type that will grow in pretty much any soil as long as the climate is sufficiently humid.

When to plant Calla Lily bulbs?

Although calla lilies are known as “spring tubers,” in tropical climates or USDA zones 8-10, calla lilies thrive outdoors year-round. They can be planted at any time! In other areas, they can be planted when the temperature is above 55 degrees F (below 55 degrees, calla lilies stop growing). Just make sure there is no danger of frost or drop in temperature below 55 degrees for the first 12 weeks after planting.

Where to plant a Calla bulb

Plant calla bulbs in full sun or partial shade (partial shade is best in warmer climates so as not to stress the delicate calla). When choosing a place to plant, consider that calla lilies are 1 to 3 feet tall on average and about 1 to 1 1/2 feet in diameter when fully grown.

How to plant Calla bulbs

Before planting, it is important to properly prepare the soil; Adding mulch to the soil will help keep the soil temperature constant. This will help keep the plant stress-free. Mulch will also improve the texture of the soil and help retain valuable moisture. Calla lilies grow in loose, well-drained soil. Once the soil is ready, they should be planted about 2 inches deep with the developing foliage facing up. Callas need 1-1 and a half feet of growing space between each plant. After planting, water the bulbs thoroughly. It is important that the soil is evenly moist, but not saturated. Depending on the cultivar, soil temperature, and weather conditions, calla lilies can be expected to flower within 60-90 days.

How to take care of Calla bulbs

Callas, like most other bulbs, spread to produce even more bulbs. These bulbs can be dug up and replanted elsewhere. In tropical climates (zones 8-10), calla lilies can be left in the ground for the winter without problems. In other places, harvest the bulbs before the first frosts, remove excess soil, allow them to dry in direct sunlight for a few days, then store in a dry place with a temperature between 50 and 60 degrees F. Replant again in spring after the the ground warmed up and any danger of frost passed.

The calla lilies (especially Zantedeschia) are not real lilies but they are graceful, sensual, suggestive and exotic. They are related to Jack-in-the-pulpit and grow from tuber-like rhizomes. Their serene beauty evokes a sense of calm and elegance, and many gardeners are shocked to learn how easy it is to grow these plants outdoors.

“>All About Calla Lilies

Calla lilies look a bit like a lily, but true lilies, like the Easter lily, have large blooms that are actually flowers, with six large petals. The great floral show that calla lily offers is not even a real flower, but rather a modified leaf (called a spat). The spat wraps around the plant’s tiny orange flowers crowded together on the central spike.

Calla cultivars offer a variety of spat colors, from standard ivory to orange, pink and yellow. A spring-planted plant develops spats and flowers in mid to late summer, and they last for weeks. You’ll see flowers much sooner in areas where callas are hardy, in U. S. Department of Agriculture plant hardiness zones 8 through 10.

The calla grows3 feet tall and almost as broad, with very large, shiny sagittal leaves. You can find varieties with brown, purple, burgundy, light green, dark green and even multicolored foliage.

“>Planting and Caring for Callas

To grow callas outdoors, plant the rhizome 4 inches deep with the tips pointing up after the last few spring frosts. Select the location with porous and well-drained soil, choosing a sunny location in colder climates, but a semi-shady location in warmer regions. Water whenever the soil is dry, being careful not to overflow.

No fertilizer is required if the soil is fertile or enriched with organic compost before sowing. Excess nitrogen produces large leaves but fewer flowers.

Expect the calla to bloom for several months. After the plants have finished blooming, leave the leaves in place until they are healthy. When it starts to fall or is hit by frost, cut it to ground level.

“>Overwintering Calla Lilies

In zones 8 to 10, where calla lilies are hardy, gardeners can leave their rhizomes in the ground to bloom again the following summer. When this happens, the rhizomes will grow large and you may need to divide them every few years.

If calla lilies aren’t hardy in your region, you can:

  • Replant new ones next year
  • Cover the area with thick mulch and hope for the best
  • Dig up the rhizomes and try to overwinter them indoors.

To do this, dig out the rhizome and cut off all leaves except one inch of the stem. Harden them in a warm, dry place for a few days, then store them in a box with moist peat for the winter.

Pest and disease problems

Like other plants, calla lilies are vulnerablefungal diseases such as botrytis and powdery mildew. Avoid this by keeping plant leaves dry and making sure plants have good air circulation. Use a fungicide to treat these problems.

Some diseases, including bacterial rot, root rot, and viral diseases, cannot be treated easily. It is best to collect infected plants and burn or throw them away.

In the case of aphids, these small, round sap-sucking insects encourage predators such as beetles and wasps. Alternatively, wash them off with a strong stream of water. The hose is also used to wash the mites that leave the nets on the plants. You can also use insecticidal soap for mites and whiteflies.

Fast facts

Canna and Calla lilies grow well in hot spots throughout Minnesota. Although the names are similar, the plants are not that similar and not even a real lily!

Reeds and calla lilies are not hardy in Minnesota, but they can be grown as annuals and potted plants or their rhizomes can be hibernated indoors.

Reeds and calla lilies come in many different flower colors and leaf types and add a dramatic touch to your garden.


Calle or callas (Zantedeschia species) are not true lilies. They are related to the pulpit jacks and the caladium. Unlike jack-in-the-desktop, they’re not immune to Minnesota. Tuber-like rhizomes should be dug up and kept indoors during the winter.

Callas have a broad, trumpet-shaped flower called a spat that wraps around the finger-like spadix. The spat is actually a modified leaf and may be white, yellow, peach, orange, red, pink, purple or bicolored. Spadix contains small real flowers. Its leaves are shaped like an arrowhead and are green or green with silver or white spots.

Zantedeschia aethiopica, a white calla, is native to Africa, where it is considered a weed. The flowers can be quite large, with a spat up to 10 inches long and a yellow spadix. It has also become naturalized in warm parts of the U. S., such as in California, where it is an invasive species. Since it is not immune in Minnesota, invasiveness is generally not an issue here.

Calla lilies can be grown as houseplants in a sunny location, but for best results, plant them outside and enjoy them at home as cut flowers. They should bloom from mid to late summer for about a month.
