Aloe Helenae Summary

Aloe Helenae Physical Characteristics

This plant is considered one of the smaller tree aloes. It can grow up to thirteen feet tall. The stem can branch at the base causing the plant to have two or three branches. At the end of each stem branch is a rosette of leaves. The rosette’s leaves can be as long as four feet. They curve outward lengthwise and inward widthwise. Its lance-like leaves are olive green, but their color may turn red if you expose the plant to intense sunlight.

Aloe Helenae blooms in early spring from a singular inflorescence that grows from the rosette’s center. The flowering stalk produces red buds from the top, which opens into yellow. The entire flowering section is about six inches long. The flower tapers towards the top, making the plant look like blazing red spears.  The leaves have spikes on the edges. Aloe helenae’s roots are shallow and fibrous.

Aloe Helenae Plant Care

It requires watering, but you must be careful not to give it too much or too little. Waterlogging is as dangerous to this plant as it is for all succulents vulnerable to root rot. Aloe Helenae needs to grow in loamy, well-drained soil. You can enhance its drainage by adding sand and gravel to the soil. Also, the substrate must have a measure of organic matter in the compost to nourish the plant. This succulent can survive in bare soils in its natural habitat, but you can enhance its growth by applying cactus and succulent fertilizer once or twice in the growing season.

It grows best under direct sunlight but can also do well under partial sunlight, especially when you want your leaves to appear green.

DO YOU KNOW? Caring (propagating, pruning/trimming, beheading, watering, …) is a set of skills that is widely applicable to succulents. Read the in-depth guide here >>

Aloe Helenae Growth

You can propagate the plant using seed, stem cuttings, or offsets. These seeds can be harvested from the plant or bought from a nursery or plant shop. The process is typical of seed propagation for succulents. Offsets and stem cuttings follow the ordinary succulent process. However, offset propagation is preferable as the plant gets established faster. You can repot if it doubles in size and protects the aloe from mealybugs, scales, and aphids.
