Variant

Cyrtosperma Johnstonii, also known as Alocasia Johnstonii, is a truly striking and rare plant native to the wet tropical regions of the Solomon Islands. It is highly valued by collectors for its dramatic appearance and exotic qualities. This plant features long, robust petioles that are reminiscent of reptilian skin, adorned with pink, brown, and red streaks which enhance their prehistoric look. Adding to its dramatic appeal, the petioles are equipped with small, dark thorns. The leaves of Cyrtosperma johnstonii are large, arrowhead-shaped, and can grow 2 to 4 feet long, displaying a lush dark green colour with prominent pink to red veins. The plant produces distinctive flowers that rise high on the petioles, featuring a black spathe and a contrasting white spadix. This unique plant thrives in warm, swamp-like conditions, making it a challenging yet rewarding addition to any tropical plant collection.

The plant comes with a default nursery pot. The nursery pot is usually 0.5" - 1" smaller than stated to fit into the same size decorative pot. Washable Paper Planter Bags are sold separately.

Care Guide

How to take care of Cyrtosperma Johnstonii

Sun: Indirect

Cyrtosperma Johnstonii should not be in a position to see the sun directly, although early morning or late evening sun is fine. Filtered sunlight through a sheer curtain is best and most homes are comprised primarily of indirect sunlight. The best spot for them is where they do not see the sun during the majority of the day but still get bright, indirect light.

Light: Medium - Bright

Cyrtosperma Johnstonii will thrive in bright light, but also can tolerate medium light. A good medium-light place in your home would be in the middle of a room that has a regular size window. They can be placed anywhere between the middle of the room and the window. Remember that plants will grow based on how much light they receive.

Water: Keep evenly moist

Cyrtosperma Johnstonii likes the soil to stay consistently moist, but not soaking wet. Give them water whenever just the surface of the soil is starting to get dry. Expect to water more often in brighter light and less often in lower light.

Humidity: High

Cyrtosperma Johnstonii likes a high humidity environment, give them a mist daily or as often as possible. Alternatively, you can put them around a humidifier. Although they won't die if they don't receive enough humidity, their leaves may have some dry, crunchy, or yellow edges.

Pet Caution

Cyrtosperma Johnstonii is moderately toxic and can cause some adverse reactions when ingested so it is best to not let your pets eat it, which we advise for all plants in general. The severity of the reaction will depend on how much of the plant is ingested but, if you know your pet typically does not eat your plants, this plant will be suitable for your home.

Plant Story

Introducing the Cyrtosperma Johnstonii, a rare and exotic plant native to the lush, wet tropical biome of the Solomon Islands. This intriguing plant, first described in 1882, carries a prehistoric essence, bringing a piece of ancient natural history into your home or greenhouse. Celebrated not just for its rarity but also for its dramatic appearance, Cyrtosperma Johnstonii symbolizes endurance and the mysteries of the natural world.

The Cyrtosperma Johnstonii is known for its long, robust stems that showcase a reptilian skin texture, adorned with pink, brown, and red streaks. These striking petioles are equipped with small dark thorns, enhancing the plant's ancient, almost Jurassic appearance. The large, arrowhead-shaped leaves can grow 2 to 4 feet long and are a dark green colour with striking pink to red veins, adding to its dramatic visual appeal.

The flowers of Cyrtosperma Johnstonii are equally spectacular, held high on the petioles. They consist of a black spath—a kind of leaf-like bract that encloses the flower clusters—with a contrasting white spadix at the center. This distinctive flowering structure adds an exotic flair and is a conversation starter for any plant enthusiast.

Caring for the Cyrtosperma Johnstonii requires specific conditions to mimic its natural habitat. This plant thrives in warm, humid environments similar to damp, swamp-like areas. Keeping the plant in a warm greenhouse with regular watering will help maintain the necessary humidity and temperature. Interestingly, it has been observed that while the ambient air temperature can be cooler, maintaining warm water temperatures can encourage growth, suggesting a versatile adaptability in cultivation settings.

When watering the Cyrtosperma Johnstonii, ensure consistent moisture, as this plant is accustomed to swampy conditions. The use of a tray with heated water can help maintain the ideal humidity and temperature, supporting its health and vibrant appearance.

By introducing the Cyrtosperma Johnstonii into your collection, you welcome a piece of prehistoric wonder and exotic beauty. It’s not just a plant; it's a living relic of the natural world's ancient past, inviting you to delve into the mysteries and resilience of nature's creations.
