Aeonium Nobile Care and Propagation: A Complete Guide

By

Aeonium nobile succulents are beautiful, easy-to-grow plants that can be a great addition to any garden.

They are a rare type of Aeonium, and they grow in a rosette shape.

This article will teach you everything you need to know about caring for these plants so that your plant grows healthy and strong!

Overview

Aeonium nobile, also known as the ‘Noble Aeonium’, is a flowering plant native to the Canary Islands.

The Aeonium species is a member of the Crassulaceae family and has several varieties that are also endemic to the Canary Island, such as:

Aeonium nobile is a succulent plant that grows large rosettes of fleshy green leaves, sometimes variegated with reddish or brown colors.

Noble Aeonium rosettes grow up to 15 inches in diameter on average. The leaves are up to 2 inches long and up to 1.2 inches wide. 

The Aeonium nobile succulent plant produces a large inflorescence that rises on a red stalk with many small red star-shaped flowers in late winter to early spring.

This Aeonium variety only flowers once before it dies.

How To Care for Aeonium Nobile ‘Noble Aeonium’

Aeonium nobile care is a fairly easy process for beginner gardeners and succulent enthusiasts.

Below you will find the main aspects to consider when caring for an Aeonium nobile succulent.

Sun Exposure & Light Requirements

The Aeonium nobile plant requires full to partial sun exposure to grow a healthy, vibrant plant.

When aeoniums are grown in a shady or partially shaded environment, they tend to lean toward the light source and become leggy with spindly branches.

Eventually, this leads to poor growth because less sunlight reaches the lower leaves, which is vital for photosynthesis.

The Aeonium nobile succulent plant does best when grown outdoors.

When Aeoniums are grown outdoors, they should be planted where they will receive about four to five hours of sun exposure each day during the summer and two to three hours per day in the winter months.

If Aeoniums are grown indoors, they still need a fair amount of sun exposure. Artificial lighting will not be enough to grow a healthy plant because the light is too intense and doesn’t provide the same spectrum as natural sunlight does.

When grown indoors, they should be located near a south-facing window, so they get a minimum of six hours a day in natural light.

Watering Requirements

When watering the Aeonium nobile succulent, you can either water thoroughly or allow some dry time before watering again.

Keep your attention on whether or not any rosettes have turned yellow, which would indicate that they need more water, as these plants are very sensitive to underwatering.

The best time for watering is in the morning or evening so that they receive a good night’s rest. However, this can vary depending on your climate and weather.

If you prefer to allow some dry time before re-watering, wait until after a rainstorm has passed or if there has been heavy dew accumulation.

It should be noted that these plants will do just fine with only one thorough watering every two weeks during winter (this does not apply when it is hot).

Soil Requirements

Aeonium nobile succulents are cactus-like plants which means they need a soil mixture that is porous and well-drained. This can be achieved by using a light potting mix for succulents or adding sand to a regular potting mix.

If a potting mix is used, a soil mixture should be created using a combination of peat moss and vermiculite or perlite.

Aeoniums can also grow in a standard potting mix as long as it has been amended with more sand than usual, especially if the plants are being grown outdoors where there may not be good drainage.

A cactus/succulent mix might also be a good potting mix to use.

Temperature and Humidity

Aeonium’s natural habitat is a dry, sunny rock outcrop in a hot and arid climate.

The ideal temperature for an Aeonium nobile plant should be between 18°C – 24°C (65°F-75°F).

The plant also prefers a relative humidity of 40% to 50%. You should keep the Aeonium nobile in a bright, well-lit area.

Fertilizing

The Aeonium nobile is not a heavy feeder and will be just fine with one fertilizer application per year, spaced out evenly during the watering cycle.

However, if you want it to really thrive, then fertilizing twice or three times a year would be beneficial.

You can use a half-strength balanced fertilizer a couple of times a year or a full-strength balanced fertilizer once a year.

Apply the fertilizer at a rate of about one teaspoon per gallon, and then water in as usual.

Potting and Repotting

Potting Aeonium nobile is a pretty simple process.

First, put the Aeonium into a pot that’s at least twice as deep and wide as it was in its previous container if you’re transplanting from another pot.

Ensure the drainage holes on the bottom of your new planter are not too high up for water to flow out easily.

Fill with well drained soil mix until firm to touch, but there is still some room for more (a little less than halfway).

Gently set your plant down, so not much extra dirt falls off, then fill any empty space with soil and pat down firmly all around using both hands, pushing down while turning slowly in each direction like kneading a ball of dough.

Aeoniums need a potting mix that is very loose and porous, making it easier for their roots to breathe and drain well.

If you’re planting a new Aeonium in your garden or flower bed, make a hole at least a couple of inches deep and wide, then fill it with a mix of half soil and half sand.

Once you have the Aeonium planted in either a pot or garden bed, water well so that there is no dry patch on top of the dirt before leaving for a few hours (or overnight).

Pruning

The Aeonium nobile does not require regular pruning, as a well-grown plant will have a natural, unruly shape.

It is only necessary to remove any dead or damaged foliage in the spring and summer seasons.

Do this by cutting off with a sharp pair of garden shears at a 45-degree angle just above a lower leaf node on an established branch.

Be careful when pruning out old leaves, as it may take a long time for a new leaf to grow back.

It can also be helpful to remove old foliage that has turned brown to allow light into the plant’s interior. However, this should not happen too often, as Aeoniums are also a very slow-growing plant.

Pests and Diseases

One of the biggest problems with Aeonium nobile plants is that they can be susceptible to various pests and diseases.

Fortunately, most Aeonium plants are not a pest magnet or disease-prone.

The best way to combat any potential issues is prevention.

  • Keeping your Noble Aeonium on the dry side will help prevent mildew from forming and keep mosquitoes away from it too!
  • When choosing where to place your plant, ensure there’s plenty of air circulation around it, which also helps ward off pests such as spider mites and a variety of bugs.
  • Aeonium plants also need a lot of sun, up to 12 hours a day if possible! Be sure you’re not placing it in a location where the plant will be shaded by trees or buildings, as this can lead to more problems such as leaf scorch and stem rot.
  • Avoid overwatering when watering plants like Aeonium nobile as wet soil is an environment that’s perfect for growing pests and disease spores.

How to Care for Aeonium Nobile in Winter

Aeonium nobile winter care is a little different from summer care.

They do not handle cold well, so a little more care is needed in the colder months.

The Aeonium plant needs a winter soaking every month or two, depending on where you live.

Watering should be a little lighter in the colder months, though, because it will not evaporate quickly and does not need to hydrate so much due to cooler temperatures outside.

You can also water less frequently, like once a week, if your plant is going dormant for a few weeks during the coldest part of winter.

Also, when the temperatures drop a lot, aeoniums need a little more light. This includes a few hours of bright light during the day, and at least three or four last for a couple of weeks before spring comes around again.

When frost starts to show on Aeonium leaves, bring the plant inside.

A warm south-facing window will help keep frost from forming, and a few hours of bright light a day is perfect too.

You can also wrap your Aeonium in a sheet or blanket during cold nights for added insulation if you need to take it indoors temporarily due to an unexpected hard freeze.

How To Propagate Aeonium Nobile

The Noble Aeonium is a succulent plant that is commonly used as a houseplant. It’s also a beautiful focal point in a garden setting. 

This guide will teach you how to propagate an Aeonium nobile from leaves, cuttings, or seeds.

From Leaves

The first way to propagate this beautiful succulent type is by taking off a leaf and treating it like a cutting (leaves produce roots).

Simply take the end of the stem where it meets with the leaf, and push down along either side of the petiole until one end breaks free.

Allow the fleshy leaves to callous for a few days and then bury up to about half an inch below ground level.

Keep soil moist but not wet for best results. You can also use a rooting hormone if desired–but they’re not a necessity.

From Cuttings

To take a cutting from an Aeonium, remove a leaf by taking it off at the base of where it meets with the stem.

Remove as much of the petiole as you would for a normal houseplant to discourage rot and then allow it to callous (usually about a week).

After that point, place in moist soil up to half an inch deep or less if preferred. Keep soil constantly wet until roots form–about six weeks total.

From Seeds

This is perhaps one of the easiest ways to propagate your Noble Aeonium plants!

Simply sow a few seeds in a container with a light, sandy soil, and water every day.

This will grow into a mass of plants that you can then separate after six weeks–a perfect time to move them outside!

You’ll notice the plant begins budding at this point.

Is the Aeonium Nobile Toxic?

The Aeonium nobile is not toxic to pets and humans, but it does contain a sap that may cause skin irritation.

It is always a good idea to wear gloves while handling Aeonium plants.

Final Thoughts

The Aeonium nobile succulent plant requires very minimal care or maintenance.

This makes them an excellent beginner’s choice for those who want something low-key that won’t require much time commitment from their gardener.

With proper care, the Aeonium nobile will thrive and reward a gardener with a long-lasting, beautiful succulent.
