Characteristics of Bignonia capreolata: what it looks like and what makes it special
La Bignonia capreolata, Also known as Tendril bignonia, crossvine or Doxanta capreolata, belongs to the Bignoniaceae family, which includes numerous ornamental climbing species. Native to the southeastern United States and other temperate areas of North America, is especially valued for its versatility, resistance and ornamental beauty.
This species It can grow both as a climbing shrub and as a purely climbing form., depending on the support or guide available. Although it usually retains its leaves all year round (evergreen or perennial), can lose some of its foliage in the cold months, making it a semi-evergreen plant depending on the climate.
His climbing method is characteristic: develops leaves transformed into branched tendrils, which clings to walls, fences, pergolas, wire fences, and any vertical structure. In the absence of support, it droops its branches and can act as a ground cover, quickly covering the ground.
El foliage It is formed by opposite, compound leaves, with up to two oblong-lanceolate leaflets of bright green color that, with the passage of time, can become darker or have different shades. Bignonia capreolata can reach between 6 and 8 meters in length in cultivation, although under especially favorable conditions it can reach up to 15 meters in nature.
Another peculiarity is its stem, which is woody, flexible and glabrous (hairless), capable of developing vigorously and quickly. Its rapid growth and its ability to cover surfaces have made this species one of the favorites in vertical gardening and landscaping.
Flowering and fruiting of Bignonia capreolata
La flowering of Bignonia capreolata This is one of its main distinguishing features. Its tubular, trumpet-shaped flowers stand out for their intense reddish-orange color, with the outer edge generally in more orange tones and the interior of the corolla in shades of yellow and red. Each flower measures between 4 and 5 cm long and appears grouped in axillary clusters that can bear one to five flowers.
The flowering period usually occurs from spring to early summerThese flowers, besides being visually striking, are fragrant and a source of attraction for pollinating insects, bees and hummingbirds, thus promoting the biodiversity of the environment. After flowering, the plant produces a fruit in the form of elongated and flat capsule which can exceed 15 cm, inside which winged seeds mature.
There are some cultivars selected for the intensity or particularity of their flowers, the best known being 'Tangerine Beauty', 'Astrosanguinea', 'Jekyll' and 'Velcyll', each with slight chromatic variations.
Ornamental uses and ecological value
El Main use of Bignonia capreolata It is ornamental. Thanks to its semi-evergreen foliage and spectacular flowering, it's perfect for covering walls, green walls, pergolas, arches, trellises, fences, and also as a hedge or natural screen for privacy.
It is also used as ground cover plant In large spaces and extensive garden areas, as it can adapt to horizontal surfaces and climb when it finds vertical supports. It's ideal for creating backdrops in vertical gardens or creating lush, vibrant environments.
In addition to its ornamental value, it provides refuge for beneficial fauna, as its flowers attract bees, butterflies and hummingbirds. The Bignonia capreolata It is also valued in sustainable gardening projects for its ability to quickly cover large areas and its resistance.
Bignonia capreolata care: a complete guide
so that the Bignonia capreolata grow vigorously and bloom abundantly, it is essential to pay attention to certain specific care related to location, irrigation, substrate, pruning, and other maintenance tasks. Its requirements are quite simple, making it a recommended plant even for inexperienced gardeners.
Location and sun exposure
Location is a determining factor for the success of this climbing plant. Bignonia capreolata needs abundant sunlight to flower and grow vigorously, although it also tolerates partial shade. The choice between direct sun or partial shade depends primarily on the climate:
- En temperate and northern climate zones, it is advisable to place it in a place where it receives direct sunlight as much as possible.
- En very warm and sunny regions, especially in the south, can benefit from protection during the most intense hours of sunlight by choosing a semi-shaded or partially shaded position.
This adaptation allows the species to thrive in both Mediterranean-climate gardens and coastal areas, and even in cities with some environmental pollution, due to its robustness.
Temperature and cold resistance
One of the great advantages of Bignonia capreolata is its high resistance to low temperaturesThe plant can withstand occasional frosts down to -10°C without suffering severe damage or losing its attractiveness, although lower temperatures can affect the foliage. In temperate or warm climates, it grows as an evergreen plant.
In case of frequent or severe frosts, it is advisable protect the base of the plant and cover the substrate with a layer of mulch (organic padding) to retain moisture and protect the roots from extreme cold.
Soil and substrate type
- Recommended substrate: Mixture of garden soil, compost and a drainage component such as perlite, vermiculite or coarse sand.
- El ideal pH It is neutral or slightly acidic, although it is tolerant to slight variations.
Remember that puddles can cause root rot in a short time. It's important to ensure that the substrate has good drainage, both in the soil and in the pots.
Irrigation and humidity
La Bignonia capreolata requires regular and generous watering During its active growth stage, which coincides with spring and summer. The goal is to keep the soil moist but not waterlogged:
- In spring and summer, water so that the substrate remains slightly moist (without getting soaked).
- During winter or during dormant periods, reduce watering to avoid excess moisture.
Necessary check substrate moisture Before watering: Insert a finger into the soil; if it's still moist, wait before watering again. Excess water can be harmful for the health of the plant. If you grow in a pot, make sure the container has sufficient drainage holes.
La humidity It promotes optimal plant development, especially in dry climates. You can spray water on the leaves on hot days, avoiding the hours of maximum sunlight.
Fertilization and manure
In the abundant flowering For vigorous growth, fertilize Bignonia capreolata primarily during spring and summer. You can use:
- Organic fertilizers (compost, worm humus) applied around the base, avoiding direct contact with the stem.
- Liquid fertilizers rich in phosphorus and potassium To stimulate flowering, applied every 4-6 weeks according to the manufacturer's instructions.
In rich soils, moderate fertilization will suffice. In poor substrates, repeat every so often depending on the plant's development. Do not fertilize during the cold or dormant months.
Pruning and maintenance
Pruning is essential for control growth and maintain the desired plant shape, whether on pergolas, walls, or as a hedge. It is recommended:
- Remove dry, damaged or untidy branches at any time of the year.
- Perform light maintenance pruning regularly to promote a balanced structure and encourage aeration.
- To renew or rejuvenate old or weak specimens, a drastic pruning in late winter or early spring, cutting from the base.
After flowering (late spring or early summer) is the best time for more intensive pruning if you want to keep the plant's size down, as the plant sprouts strongly after this intervention.
Propagation and multiplication
- Semi-woody cuttingsThis is the simplest and most effective method. Select a young stem, firm but flexible, with at least two leaves. Plant it in moist soil and keep it in a warm, protected environment until it develops roots (which can take several weeks).
- Seeds or fruitsAfter flowering, collect the ripe pods, extract them, and sow the seeds in light substrate. Germination may be less predictable than with cuttings, but is still possible.
Another less common technique is the layered, which consists of partially burying a flexible shoot while it remains attached to the mother plant until it takes root.
Pests, diseases and general maintenance
- Aphids or mites in very dry environments or due to lack of vigor.
- Mushrooms in situations of stagnant water or poor drainage.
The best preventative strategy is to keep the plant in optimal light, water, and substrate conditions, and to check the leaves periodically.
In case of infestation, you can use potassium soap or organic oils Respectful towards the environment.
