Common Name: Alocasia Nebula, African Mask, Elephant Ears
Botanical Name: Alocasia nebula 'Imperialis'
This compact and rare jewel alocasia is not a plant for the set-it-and-forget-it type. This medium-care (meaning it's not low-maintenance) indoor plant needs high than normal humidity, consistently moistened soil and an understanding that it will lose leaves when it is dormant. If this has not scared you away, then Alocasia Silver Nebula might be the next best addition to your alocasia collection! Discover how to properly grow and care for this magnificent jewel alocasia!
Light
Alocasia Silver Nebulas are adaptable and can handle a range of light from low to bright indirect. The amount of light the plant receives will dictate how quickly it grows. If you want your plant to push out new leaves actively and produce the large leaves it is known for, then make sure the Elephant Ears are in a spot where it can receive plenty of bright indirect light. The plant will survive but not grow as quickly when placed in an area with lower light levels. If you bring your Alocasia Silver Nebula outdoors in the warmer months, place it in a spot that receives partial shade. Direct sunlight will burn the leaves.
Water
Water Alocasia Silver Nebula when the top couple of inches of the soil is dry. Alocasias have medium water requirements, meaning they need evenly consistent moisture, but they do not like to have continually soggy soil. Cut back on watering during the colder months if the plant is not actively growing. A sure way to know when to water your alocasia is if you see the foliage drooping. Do not wait to water if you notice this happening!
Soil
All Alocasia species love loose nutrient-rich potting soil. Use a soil medium that can retain moisture but also allows for draining excess water to avoid root rot. Most pre-mixed soils will suffice. Make sure that there is plenty of organic matter, like coco-coir, peat moss, or shredded leaves, and avoid soils that contain moisture retaining crystals. If your soil drains too quickly, we recommend re-potting your elephant ears into a compost-rich soil mixture with fewer drainage materials.

Temperature
As a subtropical plant, Alocasia Silver Nebula prefers warmer temperatures more in line with their native environment. Average room temperatures above 60°F will be perfectly adequate! If you place your Alocasia Silver Nebula on a patio or outdoor area during the warmer months, then make sure to bring it back inside well before the temperatures drop below 50°F. Avoid placing the plant near an exterior door, drafty window, or in front of an air conditioning or heating vent. These temperature fluctuations can inhibit growth and potentially damage the leaves. Keep in mind, that Alocasia Silver Nebula can go dormant in the colder months. Although they may not lose all their leaves, they will stop growing and should be kept in slightly lower temperatures to enjoy their downtime!
Humidity
Alocasia Silver Nebula houseplants thrive when they receive lots of humidity (over 50%) which makes sense given their subtropical origins. Placing the houseplant in an area with high humidity is ideal. If you live in a drier climate or just don't have an area with enough humidity, then consider using a humidifier or a pebble tray with water. These options can help give these plants the extra boost of dampness they crave. Learn how to increase the humidity for your Alocasia Silver Nebula and other indoor plants!
Fertilizer
Routine fertilizing, especially when the houseplant is actively growing, can help these plants push out new growth. Varieties known for exceptionally large leaves can benefit from feedings. A diluted complete liquid fertilizer, a fish/seaweed emulsion, or a slow-release fertilizer are all excellent choices for Alocasia Silver Nebula. Alternatively, you can top dress the soil with organic compost or worm castings to provide them with a slow and steady supply of nutrients throughout the growing season. Do not fertilize your Alocasia Silver Nebula if the plant is dormant. Learn all about how to fertilize your indoor plants!
Growth Rate
Alocasia Silver Nebula is a relatively fast grower during the warm months once its roots are established. They will fill out horizontally but will rarely exceed 3’ in height when grown indoors.

Pro Tips
- Rotate the pot a quarter turn every time you water your Alocasia Silver Nebula. This will ensure the plant receives even sunlight and prevent it from growing towards the light and becoming top-heavy.
- Alocasia Silver Nebula likes to be a bit root bound, so there is seldom an urgent need to re-pot. However, these indoor plants tend to outgrow their pots since they can be fast growers. When it's time to re-pot your Alocasia Silver Nebula, select a pot that is 1-2" larger than the current pot or carefully separate the roots to divide the plant and re-pot into multiple containers. Routinely dividing the plant can help keep it at a more manageable size if space is limited.
- Alocasia Silver Nebulas have a rhizome-type root system. These thick roots will store extra water for the plant. The nodes are located on the roots; therefore, to propagate an Alocasia Silver Nebula, remove a section of the root and plant it in soil. A new plant will sprout from the rhizome with enough time and the right conditions.
