The Edelweiss (Leontopodium alpinum) is a flower and plant that is native to Europe and Asia.
These flowers look very similar to snowdrops, which bloom from late spring through early summer.
It has long been cultivated as an ornamental garden flower. In addition, it is also known as Alpine Snowdrop or Mountain Snowdrop.
In this article, we will be going into detail on how you can grow and care for these beautiful plants.
About The Edelweiss Flower
The Edelweiss flower is protected in certain areas and is seen as a short-lived perennial flower.
This is because the number of edelweiss plants that will grow in particular areas will decrease every year.
When you look at this plant, the first thing you will see is its wholly-like leaves, which are bright white.
These can be spotted from over a mile away. When you get closer, you will notice that they have a light yellow coloration.
They are usually found growing around rocky outcrops and other mountainous regions.
They are a close relation to the daisy plant, and you can see that with the white flower that is produced. Each petal is made up of four parts: two lobes and two wings.
The lobes are the largest part of the petal, and they come together to form a cup shape. The wings are smaller than the lobes, and they come together to make a V shape.
The root system of these plants is very impressive. As these roots can travel and anchor themselves in very difficult terrains.
Making these a very hardy plant to grow. They would be at home in a rock garden or in a garden bed.
As the Edelweiss flower is a type of mountain flower, they enjoy cold temperatures and stronger winds that other flowers would struggle with.
Therefore, these plants will grow better in zones 4 to 7.
How To Grow and Care For Edelweiss Flowers
Your Edelweiss flowers do need some sunlight to grow properly. However, they don’t like direct sunlight.
As a result, you should try to carefully plant taller plants with your Edelweiss plants to give them shade from any direct sunlight they may experience.
These plants require water regularly throughout their lifecycle.
They prefer to be watered once a week, but if your soil is dry, then you can go ahead and give them more frequent watering.
With that being said, you want to make sure that the soil has a good drainage system. Or the roots of these flowers could begin to rot and die.
Your soil can be neutral or slightly alkaline, and it will survive very well.
This plant does not require any specific kind of soil. However, as mentioned above, it needs to be kept moist all the time. Soil that drains well is best for these plants.
You can add pebbles to help drain the water off. Also, we recommend placing rocks near your Edelweiss flowers, as the limestone that is slowly released, will help your flowers to grow.
To start growing edelweiss, you can purchase your seeds either online or at your local nursery. You should plant them in early spring.
You should sow them in small pots filled with potting mix. Make sure that you do not overwater them. Let them get used to their new environment for one month before moving them into larger containers.
Seedlings should be planted in the early spring. As a result, you should start growing the seeds indoors, while you still have four weeks left of winter.
Once the frosts have passed, then you can plant the seedlings into your garden to grow.
You should use a good quality potting mix when you are planting your edelweiss.
A mixture of peat moss and vermiculite is ideal, but you can use any type of composted material instead. You should add plenty of organic matter to the soil before planting your Edelweiss.
Once the ground warms up, you can dig holes about 1 foot deep and place your seeds in the hole. Cover them with soil and tamp down gently.
Water the seedlings thoroughly once they sprout. Keep them watered during dry spells.
As mentioned above, they are used to harsh environments, so you don’t need to worry about them during the winter months.
Edelweiss plants will enjoy having a blanket of snow protecting them, during the colder months.
However, if you do have snow, then refrain from watering your plants as the snow will do the work for you.
Although, if you don’t expect much snow during the winter months, then we would suggest planting a layer of mulch around the flowers.
You should do this during the late fall and this will mimic what the snow would be doing. Once spring has arrived, you can remove the mulch.
Once your Edelweiss plant is 3 years old or more, then you should dig up the plant. Then you need to separate the plants from their roots and replant the new flowers.
This will help your Edelweiss flowers to grow much healthier.
The best time to fertilize your edelweiss is just after you plant them. Use a balanced fertilizer that includes nitrogen, phosphorus, potassium, magnesium, and calcium.
In addition to providing nutrients, you should also apply a fungicide every two weeks.
Pests And Diseases
There are many pests and diseases that affect edelweiss. Some of these include aphids, slugs, snails, and caterpillars.
You should spray your plants with insecticidal soap whenever you see signs of pest activity. You should also clean up fallen leaves and debris as soon as you see them.
However, when it comes to diseases, these flowers don’t really deal with many.
The one thing that you may notice your Edelweiss plant suffers from is crown rot. This is due to heavy and moist soil.
This will result in the foliage of your plant wilting, and the crown of the flower may discolor. If you notice this to happen, then you must remove the plant as soon as possible.
This stops the illness from spreading to any neighboring plants.
To rectify this, clean the area, by removing any fallen foliage. Whilst also applying a fungicide and sand or gravel to the soil.
You want to encourage the soil to drain properly, so this issue doesn’t happen again. This is why it is important not to overwater your plants.
Bloom Rate Of Your Edelweiss Plant
These plants take their time to mature, hence they won’t bloom until they are two years old.
However, once they establish themselves, then you are guaranteed a couple of years of these plants blooming in your garden.
Sometimes your plant may re-sow themselves, but if they don’t then you will need to replant them.
To save your edelweiss seeds, you should collect them when they first appear. You should cut off the flower heads and store them in a paper bag. You should then keep the bags in a dark, cool location for several months.
Once the flowers have dried out, you should break open the pods and separate the seeds.
You should then rinse the seeds and spread them on a tray covered with a light coating of cornmeal. The seeds should germinate within three weeks.
