After purchasing cut anthurium flowers, trim the stems to a length of about 5 cm, then place the flowers in a fresh vase filled with tap water. Make careful to trim 1 cm off the stalk and change the water once a week. The anthuriums will bloom for up to two or three weeks in this manner, allowing you to enjoy them for a longer period of time! Although they don’t require it, anthurium flowers can accept cut flower food. Therefore, using flower food with mixed bouquets is not an issue.
How are anthurium flowers harvested?
Anthurium, also known as Anthurium andreanum, is an evergreen, tropical, perennial herbaceous plant cultivated for its particularly eye-catching foliage and stunning cut blooms.
The plant known as anthurium, also known as the flamingo flower or flamingo lily, is perfect for beds, borders, and pots and works well in floral arrangements. The spathe and spadix are vividly colored, with red being the color most frequently seen among scarlet, red, salmon, orange, pink, and white.
Cut anthurium flowers must be handled with extreme caution since they are extremely fragile and prone to post-harvest losses. By nature, cut anthurium blooms last for about two weeks before significantly deteriorating.
However, harvest stage, pre-harvest conditions, and post-harvest management all affect the quality of cut flowers. Post-harvest management entails actions to enhance the flower’s ability to maintain quality for the consumer.
Pre-harvest factors, such as genetics, environmental factors (temperature, relative humidity, light), nutrition, irrigation, and other cultural practices, account for 70% of the factors affecting post-harvest quality. The remaining 30% is determined by post-harvest management, such as stage, time, and method of harvest, pre-cooling, bunching, packaging, storage, and use of floral preservatives.
- The spathe’s size, shape, color, and texture
- a spathe having lobes that are joined or overlapping in a heart-shaped pattern.
- The spadix should be artfully and gently retracted during packing, shorter than the spathe.
- There should be no damage or infestation of any type on the spathe.
- shorter internodes and straight, strong flower stalks
The anthurium’s spathe is delicate and prone to bruising and color fading as a result of handling and a calcium deficit. Additionally, high nitrogen fertilizers decrease post-harvest life, while moderate to high potassium levels increase it. The selection of variety, which influences the future of the food, is the most significant factor, aside from environmental, nutritional, and cultural considerations. Anthurium flowers come in three varieties: regular, obake, and tulip. The most typical kind is standard, with spathe lobes that frequently overlap and sizes ranging from 12×11 cm to 20×18 cm. Obake kinds are bicolor and well-known for having two tones in their coloring. The tulip varieties have a straight, tall spadix and a medium-sized cupped spathe.
- Short inter nodes and compact plants produce a large number of suckers.
- Heart-shaped, vividly colored spathe with several blisters and symmetrical basal lobe overlap
- Spadix is less than 300 degrees off-angle from the spathe and is shorter than the spathe.
- Approximately five times the length of the spathe, erect, long blossom stalk
- able to fend against frequent maladies and pests
The anthurium blooms all year round. The flowers are cut, preferably in the morning, when the spadix is almost fully grown. When one-third to twothirds of the actual flowers on the spadix are open, it is preferable to gather flowers. To prevent base rot, flowers are clipped with a sharp knife or secateurs, leaving 3 cm on the mother plant. After being cut, the flowers should be immediately submerged in water.
For 3-5 weeks, anthurium is kept in water at 13 C. Low temperatures can be quite damaging to flowers. Storage below 13 C results in spathe darkening. cultivars with red coloring are more vulnerable to cold harm.
Maintaining water absorption and respiration for 45 minutes while pulsing with 100 ppm silver nitrate. The vase life of cut flowers is increased by pulsing them with 25 ppm Silver Nitrate for 10 minutes or 150 ppm Benzyl Adenine (BA) for 8 hours prior to shipping.
The size of the spathe determines the classification of anthurium blooms. A 30 centimeter stem should have a minimum spathe size of 3 to 9 cm. There are four grades of Hawaiian cultivars: extra, fancy, choice, and standard. In relation to the grade, the spathe size (L+W/2) can be selected as miniature (less than 7.5 cm), small (9.5–10 cm), big (12.5–15 cm), and extremely large (more than 15 cm).
Corrugated cardboard boxes are used to pack flowers. Newspaper layers and polythene sheets are used to line the box. A 102x43x29 cm box contains 120 pieces of cut anthurium, each with its spathe facing down and its stem intertwined. Shredded moist newspaper is inserted to retain humidity and serve as a cushion. Before packing, it’s also common practice to protect each bloom with waxed tissue or a plastic bag to prevent mechanical harm.
The flower’s post-harvest life is significantly influenced by the storage temperature. Due to high rates of transpiration and respiration during storage, high temperatures shorten the vase life of flowers, while low temperatures cause chilling harm. Therefore, 13 C should be the ideal storage temperature for anthurium cut flowers.
The cool chain must be kept intact while the flowers are being transported. Transport should be done mostly with reefer vans. Ice can be used to lower the temperature in the box in the absence of a reefer truck. Pre-cooling flowers will generally result in better prices for the flowers on the market, as will sustaining the cool chain with the right packing.
Anthuriums typically last for two weeks before significantly degrading. Vase life is increased by 2-3 times when commercial flower preservatives like floralife, everbloom, and roselife are used instead of natural conditions. Additionally, waxing and applying anti-transpirants on the spathe extend the life of cut flowers.
Rosette formation, floral distortion, and flower abortion:
The growth of the spathe is stunted, the flower’s stem is short, and the flower on the spadix aborts. The primary cause of this condition is genetic, although it can be avoided by limiting root pressure, encouraging plant activity, lowering temperature, quick ventilation, cooling, and humidification systems. Raising the EC of the media and lowering watering can also help to limit excessive root pressure.
Cracks:
When there is an active growth phase and a brief increase in relative humidity, this condition frequently develops near the spathe margin. The greatest way to lessen cracks at night is to eliminate humidity.
Floppy Ears:
In the early stages, the flowers’ basal lobe is not fully opened. Variety affects this condition. No recognized cure exists.
Sticking:
The spathe is stuck in this instance, preventing the flower from opening. Sticking depends on the type and is more common during periods of rapid growth. The greatest feasible solution to lessen stickiness is a lower relative humidity. This issue can also be minimized by manually loosening the blossoms in the early stages.
Jamming:
Under arid environments, jamming is a significant variety-dependent feature that happens more frequently. Due to the leaves being coiled too tightly around the bloom, the blossoms become stuck in the sheath. The frequency of this disease is higher in cultivars with lengthy sheaths. The best cure is to maintain a moderate moisture level in the growing medium.

How are anthuriums kept from blooming?
Anthuriums are renowned for their extravagant, exotic flower bracts, which frequently bloom all year long and appear in vivid hues of red, pink, and white. Therefore, it can be very upsetting if your anthurium isn’t flowering while generating foliage that seems healthy.
Why isn’t my anthurium in bloom? Since anthuriums are fussy about their surroundings, problems like wet soil or inadequate illumination might keep them from flowering. By giving your anthurium plenty of indirect sunlight, appropriate watering, high humidity, and weekly feedings with diluted phosphorus-rich fertilizer, you may encourage it to bloom.
Seek out a copy of my book, “Houseplants Made Easy,” if you want to maintain all of your indoor plants healthy and flowering year after year.
How to prune an Anthurium
Continue as follows:
- Remove any brown or yellow leaves first. You can cut them off with your secateurs if they are difficult to remove.
- Snipping off the flower’s stem at the plant’s base is the best technique to get rid of faded blooms. This prevents the plant from using its energy to creating seeds rather than a lovely new blossom.
- Next, consider the Anthurium plant in its whole. Remove any leaves that don’t follow the plant’s natural shape. These are the ones that grow off at an awkward angle or are too tall. Keep at least four of the plant’s leaves attached at all times to prevent over-leaf removal.
- Finally, sprinkle water onto the leaves and stems using the plant spray.
What is the shelf life of cut anthurium flowers?
When you purchase a bouquet of cut flowers, you want them to maintain their beauty as long as possible. We’ve all experienced this at some point: we bring a lovely bouquet of flowers home, only to find out a few days later that they’ve already started to wilt. What a loss! Which cut flowers will therefore stay the longest? Some of them are introduced to you in this article.
Which cut flowers will last a long time?
Flowers from anthuriums can easily stay beautiful in a vase for two to three weeks. These flowers have strong stems and survive a long time. Anthuriums require relatively little maintenance and can maintain their attractive appearance for a very long time.
There are many different sizes and varieties of anthuriums available for cut flowers and potted plants. You can choose among flowers with heart, tulip, or cup shapes for their blossoms. Additionally, they come in a variety of colors, such as pink, orange, purple, yellow, salmon, brown, and even black. Select a variety with colorful flowers if you want to make it even more colorful.
How is anthurium pollen obtained?
A few days before the flowers are ready for breeding, the spathe unfolds and exposes the spadix in the aroid genera Anthurium and Spathiphyllum (which have bisexual blooms). The entire spadix is covered in many, bisexual blooms that are of the same size when the spathe is unfurled. In Anthurium, fresh flowers open up every day, starting at the base of the spadix and moving progressively towards the tip over the course of two weeks (Figure 2). Stickiness to the touch and a shimmering gloss on stigmatic surfaces are signs of pistillate (female) receptivity. Sometimes, little drips of exudate are visible. More than one day may pass before flowers stop becoming responsive. In contrast, a Spathiphyllum spadix’s blooms all bloom at the same time (Figure 3).
Floral emasculation is not necessary because the stigmatic surfaces of Anthurium and Spathiphyllum both turn dry and brown before the pollen dehisces. Beginning along the spadix, anthurium pollen often appears at the bottom first before moving up to the tip (Figure 4). Because each pistillate bloom matures differently, anthurium pollen can be produced for up to two weeks. Wind does not distribute anthurium pollen. Collect the pollen on your fingertips, then gently brush it into the receptive stigmas of the female flowers (Figure 2).
Inflorescences of Spathiphyllum produce pollen throughout the course of three to four days (Figure 5). Using a brush is recommended since Spathiphyllum pollen is lighter and more likely to be distributed by air currents. Gently tap the Spathiphyllum inflorescence over a container before attempting to pollinate it, catching the pollen as it falls. Use a delicate brush to apply subsequent transfers.
How are anthurium seeds collected?
Both male and female anthurium flowers bloom, with the female blooms appearing sooner. This means that an individual anthurium is unlikely to bear fruit unless you have many plants with flowers in various stages of development and of different sexes. There are no seeds if there is no fruit. You must find a solution to this issue in order for anthurium to reproduce via seed.
The first step in growing anthuriums from seed is to deceive your plant into generating the required amount of seed. The blooms start off as female and then develop into male flowers that release pollen. Take pollen from a mature male and put it in the fridge. The spadix will be rough and may be oozing liquid if you have a receptive female.
Apply pollen on the enlarged spadix using a little painting paintbrush and your pollen. With multiple anthurium plants that grow at various times, the method is much simpler. Given that seed is scarce, you will likely have to source it in this way. Since cuttings and tissue culture are more prevalent, the method of anthurium multiplication via seed is not the preferred one.
After the spadix has been pollinated, the organ will gradually transform. Fruit development will take six to seven months. Fruits that are ripe protrude from the spadix, turn orange, and are rather simple to remove from the organ.
Before propagating anthurium seeds, sticky pulp that covers the seeds inside the fruits must be removed. The simplest way to do this is to repeatedly immerse the seed in liquid while whirling it to help wash the pulp out. Place the clean seeds on a piece of paper towel to dry.
Do anthuriums produce several blooms?
Any beginner anthurium plant owner may find it to be a concerning event.
Your anthurium’s heart-shaped leaves, which were once lush and lovely, have recently began to wilt and die. What went wrong might be your initial thought. Your next question might be whether your anthurium plant is indeed dead. Not to worry! In fact, what you’re seeing is a perfectly natural phase of the anthurium life cycle.
Anthuriums are tropical plants that are sometimes referred to as “flamingo flowers” because of their vivid hues.
Anthuriums can bloom all year long if given the right care, and each bloom lasts for two to three months. Your anthurium may generate up to six blooms every year by simulating the circumstances of their native rainforest home. You can take steps to support the growth of your anthurium plant as it moves through its life cycle. For the best anthurium plant health and reblooming prospects, adhere to these instructions.
