How do I identify a Peperomia graveolens?

You could easily identify this  since it generally has a red stem, bright shiny and v shape red leaves. Hence it carries reddish glow with it. In addition to this, normally the leaves of the Peperomia graveolens plants are thick. However, the flowers of Peperomia graveolens plants are more whitish yellow in color and the sizes of the flowers would vary  from 10-inches or 25cm.

This is a shrub which could be grow up to 10 inches in height and 24 inches in width if we give it the  required proper care. Plants growing indoor could grow  even taller since they will bend towards the direction of the light.

Growth rate

We should grow Peperomia graveolens ideally in areas where it gets bright sunny light.  However, there will be no harm for growth even if it gets lower level of light. You should not plant the Peperomia graveolens under direct sunlight. You could ignore that  if it gets low level of sunlight. If you have placed the  plant  under direct bright sun light, you should take necessary steps to minimize the  level of sunlight it gets and to protect it.


This is a plant which prefers to grow  in a warm atmosphere. It will be difficult for them to survive if the temperature falls under 54 degrees Fahrenheit (12 degrees Celsius). 65 – 75 degrees Fahrenheit (18 degrees Celsius – 24 degrees Celsius) would be the most suitable temperature range for a proper growth of Peperomia graveolens plants.


Mid humid conditions would be the ideal humid condition for the survival of the Peperomia graveolens plants. It will be very effective if we can apply a light mist on the leaves. One option of doing it would be applying a little mist with water and wiping them smoothly. You really don’t have to worry on Humidity too much  since these plants are tropical plants.

Is it cold hardy

Peperomia graveolens are not cold hardy. We have to make sure that you do not place these  plants under 60° degrees Fahrenheit.


Hardiness zones of them would be from 10a – 11b from: 30 degrees Fahrenheit (-1.1 degrees Celsius) – 50 degrees Fahrenheit (+10 degrees Celsius)

Watering Requirement

You should water these plants in a  moderate and in a  consistent way at the same time. Keeping the Peperomia graveolens plants moist would be ideal to have a proper growth of them. Watering the plants from bottom to top would be one good way of watering them. If you let the plants  be in soggy condition that will lead to the root rot.

You should minimize the watering activity during the winter months. We should ensure that the first inch of the soil is dry  before proceeding with watering with the rest. If we don’t water these plants properly it will become a major concern for the growth of them.

Soil Requirement Type / pH

The best type of soil for a proper growth of Peperomia graveolens would be moist, humus rich peat based or well-draining soil. One part perlite or sand and two-part peats would be the perfect succulent plant mix. Besides that, there are other ways of mixing it too which are effective as well. You should  utilize a fertilizer twice in the growing season so that the outcome will be better. Best recommended PH of the soil would be 5.1-5.5 (Strongly acidic) and 5.6 – 6.0(acidic).

Flowering and Fragrance

Generally, the flowers of  Peperomia graveolens would grow up to 3’ inches high  and they will grow on the long stems and the flowers would be small. The flowers reflect an image of a rat’s tail and you could shop them in  green. The flowers will carry yellowish – white glow too. They don’t have any fragrance despite the word graveolens is means bad smelling.

Pot size Potting and Repotting

It will be more productive and effective if we can use well-draining pots with sufficient drainage holes. You should repot them once you see they are rootbound. You do not need to do repotting always. It will be productive if we can repot  if the roots have totally taken over the pot so that consequently it can absorb the nutrients of the soil.

Where to Plant?

These plants would be everybody’s favorite since we could grow them in small pots.  This is a famous house plant since it’s very attractive and doesn’t make more trouble for you. Due to these, we can easily grow them in a container indoors near a window directing them in the right direction where it will get  proper sunlight. This would be someone’s desk plant at office as it carries a lot of ornamental value too.

Fertilizer and time of year

You should Fertilize  them in a very minimal way as it does well despite whether you  fertilize it or not. On the other hand, fertilizing them in the growing months will add more value. You won’t be disappointed with the faster outcome as well. If it’s necessary to fertilize them, you could  use an all-purpose houseplant fertilizer once a month.


Peperomia graveolens are summer dominant. Literally, these plants will do the majority of their growing during the fall to winter months.

How do you propagate a Peperomia graveolens?

We could propagate a Peperomia graveolens by simply by stem cutting or by leaf cutting. We can try both ways and see the best possible way to propagate them. Later we can  identify the best option for us. We can try in small quantities for a start for that.

Leaf Cutting 

Arrange the pots or the tray that you wish to use for this whilst using balanced mix of potting mix and perlite. We should be vigilant on the cleanliness of the trays and on the pots.  The equipment which we use  for this should be fungus free  as if not all our effort will go in vain. Start the process off with cutting a suitable leaf of the plant with clean equipment like scissors / pruning shears. Best would be to cut the leaf  into 2-3 pieces and then dig them in the rooting powder which will consequently create new roots.

It’s better if we can make a specific spot to plant the cut leaf.  . then it  will be convenient for us  to plant them in the potting mix. After that you could plant the cut edge in the mix and cover it by the potting soil appropriately. It is very important to not overwater them and to balance the watering process. Besides that, you should place it where it does not get direct sunlight but partial sun light. You should cover the Cuttings as well.

However, you should take off the covers daily for a few hours  to not have any fungal disease. You could spot new roots coming up from the cut edge .Ultimately the leaves will begin to show up. Depending on your wish you may plant them in different pots in a timely manner.

Stem cutting 

We can follow the same initial steps as above for leaf cutting option as well. We can cut an appropriate stem off the plant ideally with a couple of leaves. Make sure you use  the aforesaid equipment with the same conditions.

You can ideally remove one or two leaves from the stem as then a tiny part of the stem would be exposed. Just like the leaf cutting option we can insert the edge of the stem into the rooting powder whilst making room in a small hole for that. We may go ahead with the same steps as above for the rest. The outcome of this whole process will appear in approximately about 2-3 weeks.

How do you repot a Peperomia graveolens?

Repotting is not quite essential for peperomia graveolens frequently. However the  best would be to use one size larger than the one which you have currently grown them in. It would be ideal if we can repot these plants from 2-3 years as if not the drainage of the pots could be minimal. That is because the potting mix would be  too old.

When we start repotting, we should apply half of the new potting mix whilst keeping the other half separately. You should remove the Plant  smoothly from the existing pot and you should plant  it in the new pot whilst adding the separated new potting mix around the plant. In this instance we should ensure that the plant does not carry the old potting mix into the new pot. Final step would be to firm the soil and water them without over watering it.
