Asparagus Fern is a type of asparagus “houseplant (insert houseplant here) Do you want to add a splash of color? Asparagus ferns are easy-to-grow plants that thrive almost anyplace, as the specimen in your dentist’s waiting area demonstrates. Though it’s a lovely addition to any indoor garden, keep in mind its true identity: It is poisonous to dogs and cats and has stinging thorns.
Asparagus fern is a bushy, feathery, fluffy perennial with erect or long, trailing branches covered in tiny, thin leaves. Small blooms or berries can be found on the vines. Asparagus fern is also known as emerald fern, emerald feather, and lace fern. It is native to Africa. Asparagus sprengeri is the most frequent variety. Ming fern and the more-groomed foxtail fern or Plumosa fern, an aggressive climber, are two more types of asparagus ferns.
Owner Mégan Twilegar felt nostalgic about a childhood asparagus fern during a visit to Pistils Nursery (pictured above): “This is the plant I remember watering for my mother when I was a kid, and I adore it,” she explained. “My mother’s plant was enormous and in a terra cotta pot, but it had these amazing mushy roots all around the base.” (If asparagus ferns appear familiar, it’s because they were all the rage in the 1970s.)
The Asparagus fern gets its name from the fact that its fronds resemble the tops of asparagus stalks. Surprisingly, asparagus fern is a member of the lily family (Liliaceae).
This plant is riddled with inconsistencies. Asparagus ferns, for example, are popularly used as houseplants yet are classified an invasive weed in other areas, such as New Zealand, Florida, and Hawaii. In addition, the phrase “The term “fern” is misleading since, unlike true ferns, the asparagus fern spreads by seed rather than spores.
How do you identify an asparagus fern?
The asparagus fern is a spreading shrub native to southern South Africa’s coastal regions. Despite its common name, it is not a real fern; instead, depending on the classification system used, it belongs to the asparagus family (Asparagaceae) or the lily family (Liliaceae, which includes plants like amaryllis, daylilies, hosta, and tulips). It belongs to the Asparagus genus, which contains the edible Asparagus officinalis as well as over 300 other species. The exact classification of this species is a little hazy, with most references to Asparagus densiflorus, but some also use the names A. aethiopicus, A. sprengeri, and Protasparagus densiflorus.
This sensitive evergreen perennial with vivid green, ferny foliage is popular as a houseplant or outdoor ornamental plant. It’s used as a groundcover or in pots outside in warm regions. Up is hardy in zones 9-11, although if sheltered, the roots can easily make it to zone 7. It is grown as a seasonal annual or container plant in more temperate locations. The asparagus fern can be found in shaded, sandy areas such as coastal dunes, open rocky areas, and woodlands in its natural habitat. It is usually found along shady roadsides and invading woodlands or rainforests where it displaces native vegetation and hinders native species from reestablishing. In some parts of the United States, including as Florida, Texas, and Hawaii, it is classified an invasive weed.
The asparagus fern has long, erect or trailing branched stems with sharp, stiff spines sparsely covering the axils. The spherical stems, which can grow up to 6 feet long and have a slight indentation running the length of them, are green to brown in color and have a shallow indentation running the length of them. Leaf-like cladodes are what appear to be leaves (short, flattened stems that look and function like leaves). From the nodes along the stem, these needle-like “leaves” appear in groups of four to eight. True leaves are scales towards the cladodes’ base that are scarcely visible. Plants feature a fibrous root structure, creeping rhizomes, and a large number of fleshy white bulbous tubers.
From spring to fall, mature plants with enough light produce little white or pinkish-white flowers in elongated clusters (racemes) along the stems. There are six tepals on each flower (3 petals and 3 sepals similar in appearance). They are little and inconspicuous, despite being fragrant, and plants planted in temperate areas rarely bloom. Plants have two sexes. Female flowers are followed by little round berries up to 1/4 inch in diameter if pollinated. The green fruits turn a glossy crimson color as they mature and contain one to three black seeds each. Many birds are drawn to the fruits, and in mild climes, they are responsible for unintentional seed dissemination. When swallowed, the berries can cause rashes and gastrointestinal discomfort, and they are hazardous to cats and dogs.
Plant asparagus fern in full sun or moderate shade; full sun plants are more compact and dense than shade plants. It thrives in moist, organic-rich soils, although it tolerates a wide range of climates and is drought tolerant once established.
The vivid green, arching stems, and airy foliage of asparagus fern make it a popular decorative. Its fine foliage has a soft or fluffy appearance and can be utilized effectively for textural contrast when combined with plants with medium or coarse-textured foliage or very large leaves. In cold climates, it can be planted in the ground alongside other annuals as a bedding plant after the final frost. In containers, this plant works well as a filler plant, especially in hanging baskets or huge urns where the delicate foliage can cascade down. When mixed with elephant ears, canna lilies, and hibiscus, it provides a tropical feel. The leaf can also be used as a filler in bouquets with cut flowers.
The asparagus fern is an excellent houseplant for inexperienced gardeners because it requires little maintenance. It thrives in direct or brilliant indirect light (the brighter the light, the faster it grows), and it can withstand periods of neglect because to its tuberous roots that store water. It thrives in a continuous moisture environment, yet in the winter, the plants should be kept drier and fertilizing should be avoided. If the soil is too dry or there isn’t enough light, the leaf will yellow and drop. To maintain the plant shaped, cut out any old or yellowed stems at the base and clip back the ends of stems.
Trim out old growth in the spring and begin fertilizing monthly for lush new growth. Because these plants can quickly outgrow their containers, they will need to be repotted on a regular basis. Because the roots are so powerful that they might break pots, larger, thicker containers may be preferable. Early in the spring, before new growth begins, is the optimal time to repot. Indoor plants can be transplanted outdoors seasonally (returning before frost), but they must be acclimated to the brighter light outside before being moved to a full-sun location. Aphids, mealybugs, spider mites, and whiteflies occasionally infest this plant, which can be found indoors or out.
Seed and division are two ways to propagate asparagus fern. At room temperature, seeds germinate after 3-4 weeks. To speed germination, scarify the seeds and immerse them in water for a day before planting. Plants can be broken down into smaller parts, or tubers can be used to grow new plants. The optimal time to divide is in the spring, but these hardy plants can be propagated at practically any time of year.
‘Sprengeri’ and ‘Meyeri’ are the two most prevalent kinds. The latter, also known as foxtail asparagus fern, has more erect stems with thicker foliage that radiates outwards from the center of the plant, mimicking a fluffy animal’s tail. This variety works well as an erect focal point in the garden or in a container with lesser plants. In warm regions, it does not generate as much seed as the species, so it does not have the same invasive potential. ‘Cwebe’ boasts copper-colored new growth and beautiful, upright, arching stems. It thrives in bright light. More compact variants include ‘Sprengeri Nanus’ and ‘Sprengeri Compacta.’
What is the difference between asparagus and asparagus fern?
I noted last week how common names might be confusing. The asparagus fern is a nice example.
These plants are not ferns, despite their common name. Asparagus ferns blossom and produce seed-bearing fruit, something ferns never do. They can also withstand harder growing conditions than real ferns, which prefer shade and moisture.
However, part of the common name is correct. Asparagus ferns are linked to asparagus that can be eaten (Asparagus officinalis). While asparagus ferns don’t produce anything edible, they are adaptable, dependable, and simple to grow, making them helpful in a variety of gardening circumstances.
Asparagus densiflorus ‘Sprengeri’ is the most commonly produced asparagus fern. This asparagus fern forms a mound of gleaming, bright green, finely textured foliage that grows 18 to 24 inches tall and broad.
The new growth resembles small spears of delicious asparagus in appearance. The delicate, lacy leaves of the young growth reminds people of ferns when it opens and grows. As a result, the popular name makes sense.
Asparagus ferns do not have genuine leaves, despite the fact that I use the term “foliage.” Cladodes are modified, flattened stems that resemble little needle-like leaves.
Tiny white flowers appear among the foliage when the plants are old enough. The resulting fruits are roughly the size of a pea, and they start out green before turning a lovely crimson color.
Asparagus ferns may be grown from seed pretty easily. Remove and sow the huge, tan seed from the ripe, red fruit right away.
Simply push the seeds into the surface of moistened potting soil in a container. It’s not uncommon to come across seedling asparagus ferns in a setting with mature, fruiting plants.
Asparagus ferns can grow in a variety of conditions, from full sun to partial shade. When cultivated in full sun, their leaves, on the other hand, tends to turn yellow. If they get some shade for portion of the day, their growth and color will be better.
Asparagus ferns can grow in almost any soil and flourish in both moist and dry environments. They thrive in the sweltering summer heat.
Temperatures in the mid- to low-twenties may cause the foliage to burn back, and gardeners north of Lake Pontchartrain have already noticed some damage. The plants will turn brown when temps reach the upper teens.
These plants, on the other hand, are still alive. Trim them now, and the plants will look great in the spring and early summer with plenty of new growth.
How do you take care of asparagus ferns?
Asparagus ferns prefer a humid atmosphere, so misting the plant or using a pebble tray can help it stay green and healthy. Temperatures of 6080 °F are ideal for the asparagus fern. Fertilize your fern once a month in the spring and summer with a half-strength all-purpose plant food.
How often should I water asparagus fern?
Garden plants should be watered once or twice a week to keep the soil from drying up completely. According to the University of Florida, asparagus ferns are generally drought tolerant, although they will develop at a slower rate if there isn’t enough moisture.
How do you make asparagus fern bushy?
When compared to other plants that get elongated, a leggy asparagus fern can appear unusual. You can have a lovely bushier plant and then, seemingly out of nowhere, a long stem arises. In a matter of days, this stem can grow to be 50cm or 1 meter long, and you’re left wondering why your asparagus fern looks like that. You can keep your plant if you like the way it looks, but if you don’t, let’s look at why this is occurring and what you can do to stop it.
Why Is My Asparagus Fern Leggy?
A lack of light is the primary cause of a leggy asparagus fern. Because these plants are frequently labeled as low-light houseplants, many people make the mistake of placing them in a dark corner where they receive very little light. It’s because they’re trying to grow towards the light that your asparagus fern is becoming lanky and lengthy stalks are sprouting outwards. If you observe this, the best thing you can do is relocate your plant to a brighter location. However, avoid placing your plant in direct sunlight during the day, since this might cause it to burn, especially if you reside in a hot, sunny climate.
If you don’t have access to a brighter location, your plant may benefit from grow lights such as these from Amazon. If you don’t have space near a window or live in a gloomy area, grow lights can act in a similar way as the sun, providing your plant with the light it need.
Will The Seasons Affect My Plant’s Growth?
You could notice a shift in the appearance of your asparagus fern as the seasons change. Over the summer, a plant that appears bushy and healthy may begin to show signs of damage during the winter. Your asparagus fern could very easily maintain growing during the winter if your home is warm, your plant is consistently hydrated, and the soil is rich in nutrients. The light could be the sole difference. Where your plant was accustomed to enjoying a full day of sunlight, it may suddenly only receive a few hours of very weak light. In other words, a plant that is good in the summer may turn lanky in the winter. If this is the case, don’t be afraid to change the location of your plant depending on the season. Changing the weather from day to day shouldn’t make a difference, but changing the seasons can.
Trimming A Leggy Asparagus Fern
You can easily clip the elongated stems away if you don’t like the look of a lanky asparagus fern. Make a cut with a sharp pair of clean scissors where you want the stem to end. You can do this with all of the elongated stems as long as they don’t make up more than half of the plant, then move your asparagus fern to a brighter position where it will grow bushier rather than leggier.
So now you know why your asparagus fern is leggy and how to fix it. However, keep in mind that it’s your plant, so if you prefer the lanky look and it’s still healthy and putting forth new growth, feel free to leave it alone and let it grow as it pleases.
What plants look like asparagus fern?
Horsetail is a weed that resembles asparagus fern in appearance. The only resemblance to asparagus stems may be seen in the former’s stems.
Despite this, it is a highly invasive weed that can grow on a variety of ground surfaces, including swampy terrain and sand dunes.
In addition, the infamous weed spreads quickly, can re-sprout from underground stems, and is herbicide resistant.
Should you cut down asparagus ferns?
The more energy and nutrients the ferns are able to transport down to the roots for the following year, the longer they are allowed to grow in the fall.
As a result, the trick is to wait until the ferns are completely brown. This shift in color indicates that they are finished for the year and can be taken down.
It’s better to get rid of the dormant, brown ferns in the late fall or early winter, if at all possible (mid-November to December). This prevents asparagus bugs from overwintering in the ferns and causing harm to the spears the following year.
Before the ferns turn brown, snow may begin to cover the ground in Minnesota. Snow can make cutting the ferns impossible, forcing gardeners to wait until spring to remove them. Remove the ferns as soon as possible in the spring if this happens.
Are there plants that look like asparagus?
A huge agave plant (Agave salmiana) may resemble a large asparagus plant, according to Clemson University. Agave salmiana grows in USDA zones 9 through 11, according to Plants for a Future. Agave plants belong to the asparagus family and shoot up a flower spike from the center of their rosette-like leaf clusters in the early spring. The flower spike grows larger and taller until it resembles a giant asparagus stalk. However, the flowers on the tall spike blossom eventually, and the aesthetic similarities cease there. When the plants are roughly 15 years old, the spikes begin to grow.
Is asparagus fern poisonous to humans?
Symptoms: This plant is not known to be poisonous. Skin irritation and dermatitis can result from contact with the sap. The prickles have the potential to cause mechanical harm as well. If you get symptoms as a result of your exposure, seek medical help right away.
