The genus Eucharis comprises 15 to 20 species in the family, and Eucharis x Grandiflora is among the most commonly grown and cultivated and best-known Eucharis species, along with Eucharis amazonica.

However, in horticulture, it is often mistaken with the Eucharis amazonica, a different species with slightly smaller flowers. 

This tropical flowering plant is native to Western Colombia and Ecuador and on the moist rainforest floors of the Andes mountains, Peru, in the upper brook of the Amazon River.

Eucharis x Grandiflora is best known for its striking clusters of fragrant, star-shaped white flowers with a cup in the center and waxy, dark green foliage.

Eucharis x Grandiflora is also generally referred to as:

This perennial bulb can also bloom two or three times a year if it is allowed to dry out after each flowering period. 

In addition, the Eucharis x Grandiflora exudes a sweetly-scented fragrance that envelopes the place.

What Are The Lighting Needs And Temperature Requirements?

Eucharis x Grandiflora is a tropical flowering plant, meaning it thrives in tropical or warm climates.

It loves bright, indirect sunlight and is best planted in partial or dappled shade spots with only 2 to 6 hours of direct sunlight daily.

This perennial bulb also prefers to be placed in a south-facing window if planted indoors. 

It also doesn’t do well in full sun as its leaves can get sunburned, and the direct sunlight can inhibit flower production.

Eucharis x Grandiflora grows best in places with normal room temperatures of about 60° to 85° degrees Fahrenheit.

It grows in hardiness zones 10 and 11, meaning it can handle a temperature of 10° to 15° degrees Fahrenheit or higher in the daytime and a temperature of 65° to 70° degrees Fahrenheit at nighttime.

This tropical perennial bulb can also tolerate a temperature of 50° degrees Fahrenheit in winter. 

In addition, Eucharis x Grandiflora loves humidity, about 40% percent if possible. 

How And When To Water And Fertilize Eucharis Grandiflora?

Eucharis x Grandiflora must be watered regularly during the growing season, but be careful not to overwater because it can cause the bulbs to rot and leaves to drop.

Ensure to keep the soil moist but not waterlogged, and misting now and then is recommended. 

After flowering, cut down the watering to allow the plant to rest, but make sure the soil is not dry completely. 

Fertilize the Eucharis x Grandiflora every two weeks during the growing season with a balanced liquid or water-soluble fertilizer to encourage foliage growth and prolific flowering.

What Is The Best Soil For Eucharis Grandiflora, And When Should You Transplant?

Eucharis x Grandiflora thrives in rich, porous soil with excellent drainage. 

If planted in a container/pot or indoor bed, the soil must be well-drained and loose and amended with coarse sand and organic matters, such as compost and manure.

The soil must also be slightly acidic with pH levels between 5.6 to 6.4. 

If you’re going to use a potting soil mixture, make sure to amend it with 25% to 50% percent pumice or perlite. 

You may also need to re-pot or transplant the eucharis plant only if necessary—when it has already outgrown the current container and roots have started to pop out of the drainage holes. 

It’s best to transplant or re-pot this plant every three years during the resting period and not disturb the roots because it can set the bulbs back, inhibiting the flowering.

Here are the steps to plant Eucharis x Grandiflora bulbs:

  • Use a small container or pot about 6″ inches in diameter with excellent drainage.
  • Fill the pot with a humusy potting mix and amend it with organic materials like manure and compost to enrich the soil and make it porous.
  • Dig a hole about 4″ inches deep and plant the bulb with the tip on the soil’s surface.
  • The bulbs grow best when pot-bound and crowded, so plant about 4 to 5 bulbs in a single pot. Doing this will boost growth and flowering.
  • Water the soil to keep the soil moist.

Does Eucharis Grandiflora Need Special Grooming Or Maintenance?

Eucharis x Grandiflora are low maintenance and easy-to-care-for flowering plants.

Pruning and deadheading are unnecessary, but you may remove the wilting, yellowish, or dead leaves and faded blooms.

Be careful not to trim the eucharis plant too often because it is susceptible to shock. 

How To Propagate Eucharis Lily?

Follow these steps when dividing offsets:

  • Simply detach the small offset bulbs from the parent plant or divide the clumps into sections in summer.

  • Water the potted bulb until the new growth begins.
