Firecracker Plant
The Firecracker Plant, otherwise known as Crossandra infundibuliformis, is an evergreen flowering shrub originating in the tropical forests of south-eastern India. It is an attractive houseplant, featuring oval-shaped deep green foliage and bright orange, red, peach, pink, and even yellow bell-shaped flowers. It blooms year-round outdoors in its native regions, and houseplants can be brought to bloom in any season if they are provided with adequate lighting and care. Firecracker plants are typically grown as low maintenance, fast-growing border plants, but can make an interesting houseplant with minimal effort.
Water as soon as the surface of the soil starts to dry. As with any houseplant, it’s important not to overwater as this can cause root rot and other issues. It should remain well-drained but not completely dry. Avoid allowing the leaves to become wet during watering.
Houseplants usually require plenty of bright, indirect light. If kept indoors, make sure the plant has access to indirect light from an east-facing window. If kept outdoors, a well-lit shaded area is ideal. In winter, make sure the plant is kept in a sunny position. Avoid direct sunlight or else the foliage will turn brown or black.
The ideal temperature for the Firecracker Plant is 68-77°F (20-25°C), although a slight variation up to 86°F (30°C) is acceptable. Temperatures below 50°F (10°C) should be avoided as this can cause foliage to drop off.
The Firecracker Plant prefers a humid environment. During hot, dry spells, it might be necessary to mist the foliage with water daily. Additionally, you can use a pebble tray to aid in enhancing the humidity.
When planting, it is best to use a well-draining potting soil that is high in organic material. Many regular potting soils contain chemicals that can be detrimental to the health of the plant. Additionally, adding a layer of organic mulch can help retain moisture in the soil.
The Firecracker Plant should be fertilized every three to four months during the active growing season. Use a half-strength, balanced fertilizer and water the plant thoroughly after fertilizing. Additionally, an Epsom salt solution can be used in early spring to encourage larger blooms.
The most common insect pest of the Firecracker Plant is aphids, which feed on the developing flower buds and leaves. If left untreated, aphids can cause serious damage to the plant. To treat an infestation, you can use an insecticidal soap or horticultural oil. It is important to thoroughly cover all parts of the plant with the insecticide. Additionally, if possible, the plant should be moved away from other plants in order to prevent a further spread of the infestation.
When necessary, the Firecracker Plant should be repotted once every one to two years. It is best to do this in early spring as this is when it is the most active in its growth. When repotting, use a pot one to two sizes larger than the current one and use a well-draining potting soil that is high in organic material. Additionally, reduce watering after repotting.
The Firecracker Plant does not need to be pruned often, but it can be done in the spring before its flowering period. It should be pruned to encourage stronger growth and to remove any dead or damaged branches. If done correctly, this will help promote new foliage and also larger blooms.
Organic mulch helps retain moisture in the soil, which is essential for the Firecracker Plant’s success. Make sure the mulch is kept away from the stems and foliage to prevent it from becoming damp and moldy.
The Firecracker Plant easily propagates by cuttings or division. To propagate through cuttings, take a 3-5 inch stem cutting from the tip of the plant. Make sure to remove any flower buds and then plant it in a well-draining potting mix. Keep the soil moist and place the plant in a warm, bright location to encourage root growth. Additionally, the plant can also be propagated through division of the parent plant at the start of its spring growth.
The Firecracker Plant may lean or become top heavy if grown in a container. Therefore, it is a good idea to stake the plant or place it in a pot with supports to keep its branches upright.
The Firecracker Plant does not need a rest period, provided it has the correct conditions year round. If the temperatures become too cold, the plant may become dormant and require little to no care until the conditions improve.
The Firecracker Plant is considered to be mildly toxic to pets. If ingested, it may cause vomiting, diarrhoea, and other general gastrointestinal upset in cats and dogs.
