Hippeastrum correiense aka Persian Amaryllis

Hippeastrum correiense is native to southeastern Brazil, where it grows in the Atlantic Forest (Mata Atlântica) region. In its natural habitat, it is a saxicolous species, meaning it grows on or among rocks. The plant thrives in the seasonally dry tropical biome, adapting to periods of rainfall followed by drier conditions.

The flower scape of Hippeastrum correiense reaches approximately 60-70 cm (about two-thirds of a meter) in height. The plant produces large bulbs that can grow several centimeters in diameter, and strap-shaped leaves that emerge alongside or after flowering. Growth rate is moderate, typical of bulbous plants.

Water sparingly when new leaves are developing, then water regularly once growth is established, typically every 3-6 days during active growth. Never let the pot sit in water, as this causes bulb rot. During the dormancy period (autumn), gradually reduce watering until the plant is kept almost dry. Resume regular watering when new growth emerges.

Use well-draining potting mix such as John Innes No.2 or quality multipurpose compost with added perlite for improved drainage. A mix of two parts potting soil, one part perlite, and organic matter works well. Excellent drainage is essential since the species is naturally adapted to rocky habitats. Always use a pot with drainage holes to prevent waterlogging and bulb rot.

During active growth, maintain temperatures around 21°C (70°F). When flowering, move to a slightly cooler location of 15-18°C (60-65°F) to extend bloom time. For dormancy, keep the plant at approximately 13°C (55°F) for 8-10 weeks. Avoid temperatures below 10°C (50°F) and protect from frost, which can damage the bulb.

Hippeastrum correiense tolerates average household humidity levels and does not require special humidity considerations. Avoid excessively humid conditions, which can promote fungal diseases like red blotch. Good air circulation around the plant helps prevent disease issues. Do not mist the leaves or allow water to collect in the crown of the bulb.

Apply a balanced liquid fertilizer weekly during the growing and flowering seasons. Begin feeding once leaves have developed and continue until September when the plant prepares for dormancy. Stop fertilizing during the dormant period. Resume feeding when new growth appears. Good nutrition during the growing season helps the bulb store energy for next year's flowers.

Hippeastrum correiense produces impressive trumpet-shaped flowers on tall scapes reaching 60-70 cm. The flowers are large and dramatic, characteristic of the genus. Flowering typically occurs in late winter to spring after a dormancy period. Each scape may produce multiple blooms. To encourage flowering, provide a proper 8-10 week dormancy period with reduced watering and cooler temperatures.

In USDA zones 9-11, Hippeastrum correiense can be grown outdoors year-round in a sheltered position with well-draining soil. In zone 8, it may survive with winter protection such as mulching. In colder zones, grow in containers and bring indoors before frost, or dig up bulbs in autumn for winter storage in a cool, dark place. The plant cannot tolerate freezing temperatures.

The most reliable method is separating offsets (small bulbs) that form around the parent bulb. Do this during dormancy or when repotting, ensuring each offset has some roots. Plant offsets in individual pots with well-draining soil and water sparingly until growth appears. Offsets take 3-4 years to flower. Growing from seed is possible but takes 3-6 years to reach flowering size, and seedlings may differ from the parent.

Repot every 2-3 years or when the bulb outgrows its container. Do this during dormancy (typically autumn) or just before growth resumes. Use a pot only slightly larger than the bulb, leaving the top third of the bulb exposed above the soil surface. Refresh the potting mix even if not increasing pot size. Hippeastrum flower better when slightly pot-bound, so avoid oversized containers.

Formal pruning is not required. Remove spent flower stalks after blooming by cutting them close to the bulb. Allow leaves to remain and continue growing after flowering, as they produce energy stored in the bulb for next year's blooms. Only remove leaves when they yellow naturally during dormancy. Never cut green, healthy leaves as this weakens the bulb.

Red blotch (leaf scorch) caused by the fungus Stagonospora curtisii is the most common disease, appearing as red spots on leaves and flower stalks. Prevent it by avoiding water on foliage and ensuring good drainage. Bulb rot can occur from overwatering. Spider mites and mealybugs may occasionally infest plants. Mosaic virus causes yellow mottling and stunting—destroy affected plants as there is no cure.

Yellowing leaves in autumn are natural as the plant enters dormancy—reduce watering and allow this process to complete. Yellow leaves during active growth can indicate overwatering, poor drainage causing root rot, or nutrient deficiency. Check that the pot drains well and the bulb is not sitting in water. If accompanied by mottled patterns, mosaic virus may be the cause, and the plant should be discarded.

Brown leaf tips or edges often indicate underwatering, low humidity, or salt buildup from fertilizer. Red-brown spots or streaks are typically caused by red blotch fungal disease—isolate affected plants and remove infected tissue. Sunburn from direct hot sun can also cause brown patches. Ensure proper watering, avoid overhead watering, and provide bright indirect rather than harsh direct light.

With a bit of knowledge and dedication, you can successfully care for Persian Amaryllis, making it a rewarding choice for those seeking a moderate challenge.

Persian Amaryllis requires abundant, bright and direct light. Placing it less than one foot from a window is the best way to make sure the plant receives enough light to survive and thrive. Depending on your region, however, the current weather can affect the placement of the plant in your home. For example, in some areas the sun may be too direct and intense, so it's best to place it farther away from the window. You may also need to adjust your placement according to the season as the sunlight can change intensity over the course of the year. If you live in a region with significant temperature fluctuations, such as a desert, you may need to place the plant a bit farther away from the window to avoid extreme heat or cold. With some care and attention, your Persian Amaryllis will be sure to bring you many years of beauty and enjoyment.

Ploi's records do not contain confirmed information on the toxicity of this particular plant. In the event of accidental ingestion of plant material with questionable toxicity by you, a family member, or a pet, it is always a good idea to consult a healthcare professional.

During the wintertime, it is common for Persian Amaryllis plants to go dormant and their growth rate may slow down. Therefore, the amount of waterings should be spaced out more.
