Sun Exposure

Quesnelia Arvensis is a flower that can thrive in a variety of lighting conditions. While it prefers shady, humid, and wet environments, it can tolerate partial sun as well, making it a versatile and adaptable plant for a range of settings. It is important to note, however, that too much direct sunlight can be harmful to Quesnelia Arvensis, so it is best to place it in an area where it can receive some sun but also have access to shade or filtered light. Proper light exposure is key to the health and vibrancy of this beautiful flower.

Soil Type

Quesnelia Arvensis thrives in soil that is well-draining and moderately acidic with a pH range of 5-7. A recommended soil mix is one that consists of equal parts of peat moss, perlite, and topsoil. The peat moss helps retain moisture, while the perlite ensures proper drainage. It is essential to avoid using heavy clay soils or those that are prone to waterlogging, as this can cause root rot and other plant diseases. Testing soil pH regularly using a soil test kit can help ensure the soil acidity is within the appropriate range for the flower to grow and thrive.

Bloom Time

Quesnelia Arvensis typically blooms in the late spring through early summer, with the flowers lasting for several weeks. The blooms of this species are quite unique, as they grow on a long, thin stem that can reach up to 3 feet in length. The flowers themselves are small and delicate, with vibrant hues of pink and purple. They are shaped like a trumpet and have long stamens that extend beyond the petals. Once the flowers have finished blooming, they will slowly fade and eventually die off, leaving behind a green and healthy foliage. It’s important to deadhead any spent blooms to encourage the plant to produce more flowers.

Flower Color

The center of the Quesnelia Arvensis bloom is typically red, with blue petals.

Hardiness Zones

Quesnelia Arvensis is a plant that can tolerate warm and humid conditions, and as such, it can be grown in the USDA Hardiness Zones of 10-11. These zones have an average minimum temperature range of 30-40°F (-1.1 to 4.4°C) and are located in tropical and subtropical regions. In these zones, the plant can be grown as a perennial, and with proper care and attention, it can thrive and produce beautiful blooms. However, it is important to note that Quesnelia Arvensis is not frost tolerant and should be protected from cold temperatures. If you live in a colder climate, you can still enjoy the beauty of this plant by growing it indoors or in a greenhouse.

Native Area

Quesnelia Arvensis is native to coastal and swampy forest areas in Brazil.

How to Plant

Fill the pot halfway with the potting mix, making sure the area around the root ball is firm, then fill it with water until moist. The plant should receive partial sun for 4-5 hours per day. It is best to keep the soil slightly moist and not to let it become overly moist.

Fertilizer should be added every few weeks in the warmer months. Make sure to follow the directions on the fertilizer label and not to over-fertilize or damage the plant.

How to Repot

Quesnelia Arvensis should be repotted every 3-4 years. Only repot it after the root system has become rootbound. Choose a pot rooting mix that is coarse and well-drained and make sure to avoid heavy soils. It is best to repot your plant in similar conditions as when it was first planted.

Remove the plant from its pot, loosen the roots and place it into the new pot. You may need to add additional soil around the root ball. Firmly press the soil down to ensure that the roots are held in place. Water the pot and make sure to provide the correct amount of light.

Flower Varieties and Their Defining Characteristics

Quesnelia Arvensis is a flowering plant that comes in many varieties. It is a species of neotropical epiphytic bromeliad, with leaves of various shapes and sizes.

There are a few commonly found varieties, including Quesnelia testudo, or the Termieri or Pointed Quesnelia, which has wide and long leaves and features a bright yellow center.

Quesnelia humilis, the Didnot or Dwarf Quesnelia, is the smallest variety with pointed and fringed leaves, and a short inflorescence of small white or yellow flowers.
Quesnelia berteroniana, the Catina or Big Quesnelia, has bright red leaves with billowy red inflorescence blooms.
Quesnelia caerulea, the blue or pale Quesnelia, is an epiphytic plant and sports leaves with a powdery greyish-green hue and a tiny white flower with a thin yellow corolla.

How to Pot and Repot

Quesnelia Arvensis can be easily potted by making sure that the correct soil type, temperature and humidity levels, and water exposure have been met. Make sure to use a potting mix and a pot that is suitable for the Quesnelia, then insert the plant into the soil. Then moisten the soil, making sure not to over-water. If you need to repot your plant, only do so after the root system is already root-bound. Choose a potting mix that is coarse and well-drained and avoid heavy soils. Follow the same process as with potting, but take extra care to make sure that the roots are firmly held in place.

How to Prune

Pruning Quesnelia Arvensis is an important part of maintaining a healthy, attractive flower. Pruning should be done to encourage new and healthy growth, and to remove deadweight, excess foliage, and branchless stems. The pruning method used depends on the type of Quesnelia. For Quesnelia testudo and Quesnelia berteroniana, the stems and leaves can be pruned with a pair of sharp scissors, making sure to cut any excess weight from the stem. For Quesnelia humilis and Quesnelia caerulea, the dead leaves should be pruned using sharp and smooth shears, avoiding any torn or jagged edges. Make sure to prune your Quesnelia’s regularly to encourage new growth and for it to remain healthy and vibrant.

How to Propagate

Quesnelia Arvensis is easily propagated by the method of division. All you need to do is cut off a portion of the plant early in the morning and repot the new division in moist soil, making sure to provide the correct temperature and humidity levels and water exposure.

Common Pests and Diseases

Quesnelia Arvensis is prone to a few common pests and diseases. Mealybugs, aphids, fungus gnats, and scale are the most common. Mealybugs can be spotted on the underside of the leaves and will cause yellow dots on the upper infected leaf surfaces; they can be treated with a soft cloth dampened in dish soap. Aphids will suck on the inside of the flower buds and may cause flower bud necrosis; these infestations can be treated by applying an insecticidal soap. Fungus gnats are the larvae of flies that attract growing medium moisture, and can be treated with more sand or grit in the mix and a preventive spray. Scale are especially difficult to remove and can be removed with a toothbrush; applying a soapy water mix is also recommended.

The plant is also prone to eelworm/nematode infestation, which can be spotted as yellowing leaves, stunted growth, and wilting. Treatment involves comprehensive soil testing and soil sterilization. Never introduce a new Quesnelia Arvensis into the same soil or pot that has been previously infected with a nematode.
