Getting seeds from ferns is a bit more complicated than obtaining seeds from other plants. The first step is to find a type of fern that is capable of producing spores. The moonwort, and the adder’s-tongue fern.
Once you find one of these ferns, you’ll need to identify if it is male or female. Ferns are unique in that they have separate male and female plants, which can be identified by looking for the presence of a single black dot on the underside of the frond.
This black dot is the sporangium, and it is where the spores are produced.
The next step is to collect these spores. The spores are very small and delicate, so it’s important to use the correct tools and techniques to ensure that you get a good collection. The spores can be collected by either brushing them into a container or by placing a damp paper towel under the frond and shaking it gently until you see a fine dust-like powder.
Once you have the spores, they need to be stored in a cool dry place until they are ready to be planted.
Once the spores are ready to be planted, you’ll need to find a medium to put them in. Sphagnum moss is a great option because it provides the ideal environment for the spores to germinate. The moss should be mixed with a small amount of potting soil and water until it’s lightly moist.
The moss and soil mixture should then be spread out thinly across a sterile container and then the spores should be sprinkled evenly over the top. Finally, the container should be sealed and kept in a warm environment with indirect light and lots of humidity.
Over time, the spores should germinate and eventually produce tiny seedlings that can be transplanted into their own individual containers.
As you can see, getting seeds from ferns is a bit more complicated than from other plants. Nevertheless, it is a fascinating process, and the end result is definitely worth the effort!

How do you collect fern seeds?
Ferns typically reproduce from spores, rather than from seeds; however, there are a few species of ferns that do produce seed-like structures. To collect these fern seeds, you need to plan ahead and begin looking for the seed heads when they start to form (normally in late summer to early fall) before they mature and disperse the spores.
Seed heads form on the underside of the plant’s fronds, often with a color different from the rest of the plant – look for bright orange or brown dots. Once the seed heads have appeared, they will ripen over a period of time, so keep checking in regularly.
Once the seed heads are brown and papery in texture, they are ready to harvest.
Carefully break off the seed head and place it in a paper bag and let it dry in a cool location. Once the seed head is completely dry, you can gently crush it with your fingers to release the seeds – this is the easiest way to obtain a lot of them.
The tiny brown seeds should come off easily and be ready to store in an airtight container. To ensure longer survival, the seeds can be stored in an airtight container in the refrigerator.
Where are the seeds on a fern?
Ferns are unique plants because they do not produce flowers like other plants do. Instead, they reproduce and spread by producing spores. The spores are located within reproductive structures called ‘sporangia’ or ‘sori’ which are found on the underside of the leaves of the fern.
The sporangia, which are small round or oval structures, contain the spores and are usually grouped in clusters. The sporangia can vary in colour from yellow to brown and contain thousands of small yellowish/brownish coloured spores.
The spores are released into the air when the sporangia dry, and the spores are then dispersed and establish new ferns.
Is it easy to grow ferns from seed?
Growing ferns from seed is not necessarily an easy process, but it is not impossible either. While a few ferns are able to be grown from seed, many varieties must be grown from spores. The best way to grow ferns from seed is to start by soaking them in warm water for 12-24 hours before planting them.
Plant the seeds in a pot filled with well-draining potting soil, cover lightly with soil, and water until the soil is evenly moist. Place the pot in a warm area with partial or indirect sunlight. Keep the soil moist but be sure to not overwater it as this can lead to root rot.
When the seedlings reach 3-4 inches in height, fertilize the soil with a balanced fertilizer, following the instructions on the packaging. Finally, make sure the ferns are in a well-lit area that is out of direct sunlight and with a suitable humidity level.
With patience, the ferns should soon show up.
How do you reproduce a fern?
Ferns can be reproduced by spores or vegetative means. Spore reproduction is the more common way of reproducing ferns. This involves the production of fern spores on the underside of leaves. The spores will then germinate and form tiny plants (prothalli).
On the prothalli, male and female reproductive organs will then be produced and will create a fusion to produce a new plant. The plant will then grow from the prothallus and reach maturity.
Vegetative reproduction is a more difficult and less likely reproduction method for ferns. It happens when the fern stem fragments and each part of the stem will create a new fern. This is rarely done since it is difficult to fragment the stem into small pieces, which will then establish itself as a new fern.
To reproduce a fern successfully, it is important to ensure that the environment is ideal. Ferns need moist soil, enough sunlight, and an appropriate temperature in order to be able to successfully reproduce.
Do ferns produce seeds yes or no?
No, ferns do not produce seeds. Ferns are classified as a type of non-flowering plant, which means that they reproduce using spores instead of seeds. These spores are located inside a pod-like structure known as a sporangium.
When the spores are released, they are blown by the wind and fallen from their parent plant to start the process of germination and growth of a new, individual fern.
How long do ferns take to grow from seed?
It typically takes three to six months for ferns to grow from seed. The time frame can vary depending on the particular species of fern and the specific environmental conditions, such as temperature and light levels, in which they are grown.
The process begins with sowing the seeds in a lightly moistened, nutrient-rich soil. The fern spore will soon germinate and develop into a prothallus. Over the course of the next few months, the prothallus will produce gametes and develop into a sporophyte — or what is referred to as a fern plant.
As long as the environmental conditions are favorable, the fern should reach maturity within three to six months.
Do ferns produce seeds on the underside of their leaves?
No, ferns do not produce seeds on the underside of their leaves. Instead, they have a reproductive cycle known as ‘alternation of generations’ where sporophytes (diploid cells) alternate with gametophytes (haploid cells).
During the sporophyte stage, spore-producing structures known as sori form on the underside of the fern fronds. These sori develop into tiny spore-producing capsules that contain millions of microscopic spores.
When the spores are released and germinate, they form gametophytes, which produce the male and female gametes necessary for sexual reproduction. The ferns do not produce any hard-shelled, seedlike structures – instead, the gametophytes are the reproductive units of the ferns.
What time of year do ferns produce spores?
Ferns produce spores at different times of the year depending upon the species. Most ferns have a specific time frame in which they produce spores. These timelines typically fall between late spring through early summer for most species.
The most noticeable part of a fern’s reproductive cycle is when their sporangia (the black, spore containing structures on the underside of the leaves) are easily visible. In the northern hemisphere, most ferns will produce spores during June and July.
In the southern hemisphere, the peak spore production usually occurs between October and December. Ferns will typically produce spores for up to two months, depending on the climate and the species. For example, the Button Fern typically produces its spores from June to August.
With more tropical climates, some ferns may produce spores throughout the summer months and into the early fall.
What do fern spores look like?
Fern spores are tiny, dust-like particles that come in a variety of shapes and sizes, depending on the type of fern species. They have a protective outer layer called an exine, which encases the living material inside, referred to as the intine.
The exine of fern spores typically appear brown or yellow in color and contain a pattern of ridges and spines, which helps them stick to different surfaces. Generally, fern spores are spherical to bean-shaped and measure between 2-105 micrometers in diameter.
Under a microscope, the exine of a fern spore appears as rows of granules, which contrast with the smooth intine beneath. Thanks to their resilient exine, fern spores are incredibly adaptable and able to survive a variety of extreme conditions such as dry heat, flooding and even radiation.
This resilience is the reason why ferns are some of the oldest and most diverse species on Earth — the first ferns appeared around 360 million years ago.
Can you see fern spores?
Yes, it is possible to see fern spores with a microscope. Fern spores appear as very small dots when viewed under a microscope. Fern spores are typically colorless and are approximately 20-30 μm in size, which is smaller than a grain of salt.
While it is possible to see fern spores with the naked eye, a microscope is required to observe them clearly. A microscope can magnify the spores so that the anatomy and shape can be distinguished. Spores can be viewed with a light microscope, with oil-immersion techniques being the most effective and allowing for high magnification and clear views.
In addition, scanning electron microscopy can also be used to observe spores in great detail.
How long do fern spores last?
Fern spores can last several years, depending on the particular species of fern and the environmental conditions in which they’re stored. Some spores have been found to remain viable for up to a decade and in certain cases, longer.
Generally speaking, fern spores are stored for many years by commercial seed suppliers, allowing time for the spores to develop and produce a new generation of ferns. The storage, handling, and environment conditions that spores are exposed to will ultimately determine their lifespan.
What month are ferns in season?
Ferns are generally in season between the months of May and early September. Depending on the type of fern you are looking for, the season may start earlier or later. When looking for ferns, be sure to choose healthy looking greenery that is currently in bloom and has a good color.
Avoid ferns that are starting to discolor, as these may not last for as long as other types. Additionally, make sure to check the health of the fern’s size and leaves before purchasing. Lemon Button Ferns, Boston Ferns, Sword Ferns, and Autumn Ferns are some of the more popular ferns that are in season during this time.
Do all ferns have spores?
No, not all ferns have spores. Not all members of the plant kingdom are able to reproduce via spores; in fact, some families, such as the cycads, do not have spores and reproduce instead through other methods.
Similarly, within the ferns, some species do not produce spores and instead reproduce by generating offshoots or by producing gemmae. These asexual methods of reproduction are called vegetative reproductions and are found particularly among the arborescent ferns.
Some species of ferns also reproduce by producing bulbils or by producing adventitious buds near the base of their leaves.
What phase are spores made in ferns?
Ferns produce spores in a process called sporogenesis. It is part of a process referred to as alternation of generations, where the plant alternates between two different life stages: the sporophyte, which produces spores, and the gametophyte, which produces gametes.
During the process of sporogenesis, cells divide to form diploid spore mother cells inside the sporangia, which then undergo meiosis to form four haploid spores. Each spore eventually develops a hard outer wall, allowing them to survive in unfavorable conditions until conditions are right for germination.
Once favorable conditions arise, the spores will germinate and a gametophyte will form. This cycle of alternation between sporophyte and gametophyte will repeat itself until sexual reproduction takes place.
