What kind of plant is cineraria maritime?

The maritime cineraria is a shrub-like plant that can reach up to a meter in height when it grows in the right conditions for it.

It belongs to the asteraceae family, being native to areas with a Mediterranean climate.

It is a very resistant plant that can be used in areas with strong winds and even in spaces near the coast where there is high salinity.

Preparing the land for this plant

You will need a soil that retains moisture well, but drains excess. To achieve this, it is best to make your own potting mix.

A good mix for this plant is 1 to 2 parts sphagnum peat moss, 1 part vermiculite, 1 part loam soil, and 1 part perlite. You can substitute coarse sand for perlite if needed. A reasonable substitute for peat moss would be coconut fiber.

Your potting mix is ​​reusable for future batches throughout the growing season. Then work the potting mix into one of your outside garden beds and replace it.

How to take care of the maritime cineraria?

Irrigation is a delicate issue in most herbaceous species, but in this case the maritime cineraria is very resistant to drought. That means it becomes a great option for those who don’t have a lot of time to spend on garden care issues.

It may be able to withstand variable temperatures throughout the year, taking care that the winters are not frozen. If there are very strong winters in your area, it is worth installing a protection mechanism.Regarding fertilization, it does not require them.If you want to give it some nutrients, that’s fine.

When is cineraria maritime planted?

The planting time will depend on the reproduction method to be used, since it accepts three ways: seeds, cuttings and layers.

In the case of seeds, the best season is spring to offer them the right environmental conditions so that they are comfortable and germinate.

In the case of cuttings, it is possible to wait until the end of flowering and collect the cuttings from what is produced by pruning.

Layers have a wider range of work than this breeding system implies, hence you can progress between spring and summer.

The best method is the cutting because it helps to obtain a new plant, independent from the beginning, with good characteristics and that grows fast.

How is cineraria maritime planted?

Sowing must be done directly on the ground because in a pot its growth will be severely restricted and it will lose its ability to flower. However, when space is limited, it is established in pots to take advantage of the ornamental value in small places.

In addition, it needs many hours of sunlight each day to develop well. It is important that the soil is capable of draining water well so as not to promote waterlogging. Of the rest, it does not need to be specially nourished.

How does cineraria maritime reproduce?

It reproduces by means of seeds that are first made to germinate in seedbeds to later transplant the small plants to the definitive place.

In these times, it is better to keep the plant in semi-shade and with a frequency of irrigation that is profitable for it to prosper.

On the other hand, the substrate used in the nursery is better than sand, since this is the ideal texture for this species.

Other alternatives that also give very good results are cuttings and layering.

How is the maritime cineraria plant pruned?

It must be applied when the flowering season has passed, since one of its characteristics is that it grows in a somewhat “explosive” way.

This means that at first glance it can seem messy and it is worth cleaning it up a bit. In this pruning it is necessary to remove the shoots that have already flowered because those will no longer perform any function.

Here you have to practice cutting above a knot. It is also necessary to cut those shoots that look dry or are in poor condition.

In the same way, the plant is capable of resisting punctual cuts during the rest of the year that help it look more attractive without this implying a problem.

The maritime cineraria is one of the most striking and outstanding ornamental plants due to the characteristics of its leaves. These are capable of decorating any environment and, the best thing is that they can be organized together with other plants without much problem.

Do you need fertilizers?

Since this plant is quite short-lived, fertilization is not strictly necessary.

Before it blooms, you can use a weak liquid fertilizer only once. Once the flowers begin to form, do not pay until they have finished flowering.

If you’re trying to get a second bloom from your plant, wait for the flowers to fade. Trim the flower stems and then refertilize. There are no guarantees that it will bloom a second time, but it doesn’t hurt to give it a try.

Pests, diseases and problems


Most of the pests that affect your florist cineraria will be sucking pests.

  • Aphids are by far the worst and most common on this plant. You’ll find them around the axils of leaves and on the undersides of leaves. To remove them, use an insecticidal soap.
  • Whitefly: This same treatment should be used for whiteflies. You’ll know you have them when clouds of tiny white bugs are seen around your plants. If you see that, look for tiny larvae on the leaves of the plant. Spray with insecticidal soap to remove them.
  • Thrips: Although less common in cineraria, thrips may be present. These black bugs are mostly found on flowers. Also use insecticidal soap.
  • Spider Mites: The last two pests are a bit more of a hassle to deal with. First of all, we have spider mites. They can be removed with neem oil or a product like Mite-X.
  • Leafminer: And finally, the chrysanthemum leafminer is known to go after florist cineraria. This leafminer is part of the Chromatomyia leafminer family. You will start to see white maze-like patterns chewed on your leaves. The latter is more difficult to treat because the larvae burrow into the leaf itself. It is best to remove damaged leaves completely. Use a powdered or liquid form of bacillus thurigiensis to prevent further colonization.


  • Botrytis cinerea looks like a gray mold. It is actually a fungus that will cause damage to the leaves of your plant. Neem oil is a good treatment and preventative. For more severe cases, use a liquid copper fungicide.
  • Powdery mildew is also common, especially since your plant loves moisture. White powdery spores will begin to form on the leaves. Mild cases can be treated with neem oil, but as with botrytis, use copper fungicide for severe cases.
  • Common rust is an occasional problem. It begins with slightly raised, whitish spots on the undersides of the leaves. Over time, the spots develop orange spore masses. As above, copper fungicide is effective against this.
  • Sulfur sprays also have a good effect against rust
  • Lastly, there are many types of soil-dwelling fungi that can cause root rot and basal rot. These tend to thrive in warm, moist soil. Use a sterile soil mix to avoid them and keep your plant in cool places.
