Plectranthus are very beautiful plants, which are used both to decorate the interior of houses and the shady or semi-shaded corners of gardens and patios. Its leaves are usually rounded, green, although there are some that have them variegated.

In any case, its maintenance is not too complicated. In fact, it is easy to find it for example in the houses of our grandparents, growing up with health and strength. So if you also want to have one, below I will explain how Plectranthus are cared for and which are the most popular species.

Origin and characteristics

Our protagonists are herbaceous plants with an annual or perennial cycle, native to tropical Africa, Japan, Australia and some islands in the Pacific. The genus is made up of about 325 accepted species, of the 1000 that have been described. They produce simple, petiolate leaves, with crenate-toothed margins, and inflorescences, usually pedunculated, composed of white or purple bisexual flowers. The fruit is a type of small nut with an ovoid shape, glabrous and with mucilage.

They are usually aromatic and hairy plants, so they are undoubtedly very interesting both for the garden and for growing in pots.

How are they cared for?

If you want to have a copy, we recommend you provide the following care:


  • Exterior: it must be protected from direct sun. It grows well in shady corners, as long as they are somewhat bright (that is, not full shade).
  • Indoor: place in well-lit rooms, away from both cold and warm drafts. Avoid putting it in passage areas as well, because when rubbing past it, its leaves would get damaged.


  • Garden: grows in soils rich in organic matter, with good drainage.
  • Pot: fill with mulch mixed with 30% perlite.


Moderated. We must avoid waterlogging, but also drought. Water an average of about 4 times a week in summer, and an average of 2 a week the rest of the year. If in doubt, check the humidity of the soil, either with a stick, or by weighing the pot once it has been watered and again after a few days.

Use rainwater whenever possible, but if you cannot get it and what you have is only calcareous water, mix the juice of half a lemon in 1l of water, and water with it. Don’t wet the leaves, just the earth; and if you have put a plate under it, empty it 30 minutes after watering.


In spring and summer it is highly advisable to fertilize it with organic fertilizers, such as guano following the instructions specified on the packaging.


Although they produce viable seeds, which can be sown in spring in pots with universal growing medium, what is done more is to multiply the Plectranthus by cuttings, also in the flower season.

Healthy chunks are cut, impregnated with homemade rooting agents or rooting hormones, and planted in pots with vermiculite previously moistened with water. They will emit their own roots in two to three weeks.

Plagues and diseases

In very humid environments they can be affected by botrytis, which causes the appearance of gray spots on the leaves. It is treated with fungicide, but the best thing to do is to control watering by avoiding puddling and never wet the aerial part (leaves).


They do not need it, although the stems can be pruned a bit in spring if you see that they are growing too much. Use scissors previously disinfected with alcohol to prevent infection, and don’t forget to disinfect them when finished.


They resist cold but not frost. The minimum temperature should not be lower than 5 degrees Celsius.

What uses are they given?

As we have seen, they can be used both as ornamental and medicinal plants, and even as edible vegetables or tubers.

What do you think of these plants? Do you dare to have one?
