Philodendron Black Cardinal - Black Cardinal Philodendron has ornamental value with mahogany stems, deep-burgundy petioles, and reddish green leaves.
Philodendron Black Cardinal also called as Black Cardinal Philodendron, is a cultivar in the genus Philodendron. It is another very popular hybrid of Cora McColley from The University of Florida/Mid-Florida Research and Education Center.
DESCRIPTION OF PHILODENDRON BLACK CARDINAL
Philodendron Black Cardinal is an interspecific hybrid developed from a series of crosses among P. wendlandii, hastatum, erubescens, imbe, fragrantissimum, and an unnamed species. The plant has been asexually reproduced by single eye and tip cuttings in the vicinity of Orlando, Fla., and has been found to retain its distinctive characteristics through successive asexual reproduction.
It is an evergreen aroid hybrid with very dense, compact, self-heading plant habit. The leaves are elliptic form, saggitate base, cuspidate leaf tip, entire margin, black red, almost black in medium to low light intensity turn to reddish-black green when mature, 45 cm long by 32 cm wide. The petioles are semi-erect to erect, 25-33 cm long, deep-burgundy.
Black Cardinal Philodendron blooms from the inflorescences that are formed by a rich burgundy colored spathe and white, 15 cm long spadix and is the reproductive portion of any aroid. The flowers are unisexual; female flowers cover the lower one sixth of the spadix, male flowers are positioned on the upper two thirds of the spadix, and the remaining portion inbetween is comprised of sterile male flowers. All parts of plant contain calcium oxalate crystals, an irritant to the mouth and esophagus.
PHILODENDRON BLACK CARDINAL CARE AND CULTURE
Cultural information should only be used as a guide, and should be to be adapted to suit you. Your physical location; where you grow your plants, how much time you have to devote to their care, and many other factors, will need to be taken into account. Only then can you decide on the cultural methods that best suit you and your plants.
Light:
Philodendron Black Cardinal grows best in bright and indirect sunlight. Exposure to the sunlight can causes a yellowish color in the leaves or a sunburn spot. Too little light can result in leggy growth with lots of space in between the leaves. Artificial light gives best results if natural light is not present.
Rotate your plant periodically to ensure even growth on all sides and dust the leaves often so the plant can photosynthesize efficiently. When dusting the leaves, also take the opportunity to inspect the undersides and keep an eye out for pests.
Temperature:
Black Cardinal Philodendron grows well in normal to warm indoor temperatures 24-27ºC (75-80ºF). They cannot tolerate temperatures which drop below about 13ºC (55ºF). In mild, frost-free climates, the plant can be grown outside in shady spots. If grown outside, night temperatures down to around 15°C and day temperatures around 30°C are ideal.
Substrate and growing media:
Philodendron Black Cardinal grows best in loose, well-drained soil which is rich high in organic matter. It also be grow in 100% sphagnum peat moss and mixtures such as peat-vermiculite or peat-perlite.
The plants benefit from repotting to a larger container when they become root bound and outgrow the original pot. A combination of half soil-based potting mixture and half leaf mould or coarse peat moss is used.
Move the plant into container one size larger only when their roots have completely filed the current one. This is done at any time of year except during the short rest period. After the long rest period the convenient pot size has been reach (probably about 25-30cm (10-12 inch)), an annual spring top-dressing with fresh potting mixture will help to keep the plat healthy. A container with drainage holes to prevent root rot is used. A cachepot is used if a decorative container is without drainage. It is necessary to cover the bottom of a cachepot with pebbles so as to keep the plant above the drainage water.
Watering:
Fertilizer:
Philodendron Black Cardinal are considered heavy feeders. Regular feeding program with a nitrogen fertilizer will increase leaf size and produces a larger, healthier plant. Throughout the months while the plant is actively growing (from spring until fall) apply standard liquid fertiliser once every two weeks. It's a nice strategy to fertilize more frequently at half strength than to apply one strong dose. Plants which mainly grows in low-light conditions require less fertilization than actively-growing plants. Moist soil requires fertilizers to avoid injury to plant roots.
Pruning:
Use a sharp pruners or scissors to control the size and shape of the plant. You can remove entire leaves by cutting them off at the base of the leaf stem. You can also remove the lower leaves if you want to reveal the plant's stem. Always wear gloves when pruning and wash your hands and tools when finished. You don't want to get the sap in your eyes or mouth.
Pests and diseases:
No serious insect or disease problems is however reported. Watch for aphids, spider mites, mealy bugs and scale. Leaf spots may occur. Root rot can occur in overly moist soils. Small leaves or long spaces between leaves show that the plant need enough light to grow.
Propagation:
Cutting and layering are popular methods of Philodendron Black Cardinal propagation. Try propagating them during the growing season. A small brown nubs are formed where the leaves meet the stem. These nubs, when in contact with soil or water, will grow roots. There are many ways to propagate this plant, the easiest being to cut a branch just below a root-nub and place it in water with a few pieces of horticultural charcoal to reduce the likelihood of rot. As soon the growth of new leaf takes place it is potted in the rich soil. Similarly it can also be propagated within its own pot by pinning vines at the root-nub to the soil with hairpins or bent wire. The root nub in contact with the soil will sprout new roots in a very short time. When the different parts of Philodendron species are rooted, the plant will greatly profited from misting several times a day.
