About Adenia globosa

Native to parts of eastern Africa like Tanzania and Kenya, the Adenia globosa belongs to the passion flower family. It grows as a spindly, climbing shrub with thin, circling stems covered in nasty thorns. The leaves are grayish-green when present, but the real stars are the greenish-white flowers. However, the plant’s most bizarre feature is its swollen, rounded caudex that looks like an alien’s skull!

This succulent weirdo can grow up to 2 feet (0.6 meters) tall in the right conditions. While it may look creepy, the Adenia globosa is actually easy to care for if you follow some simple tips. Let’s dive into what this plant needs to thrive indoors or out.

How to Care for Adenia globosa

Light Requirements

Like most sun-worshippers, Adenia globosa craves bright, direct light for 5-8 hours per day. A sunny window or patio is perfect! If growing it outside in blazing heat, provide some afternoon shade. If keeping it inside, a grow light can supplement natural light.

Water Wisely

Let the soil dry out completely between waterings for this drought-tolerant species. Stick your finger down into the pot to check for moisture – if it’s bone dry several inches down, it’s time for a drink! In winter, cut back to watering every 1-2 weeks when the plant is dormant.

The Right Soil

To avoid drowning this moisture-hating plant, use a well-draining succulent or cactus soil mix. Add perlite or pumice to improve drainage and aeration around those alien-like caudex lumps.

Food for Thought

Like a crazy plant teen, Adenia globosa needs lots of food in spring and summer to fuel new growth. Use a cactus fertilizer every 2-3 weeks during this active period, but take a fertilizer break in fall and winter.

The Perfect Temperature

This heat-loving plant thrives in warm, bright conditions around 70-80°F (21-27°C). Anything below 40°F (4°C) is too cold and could kill it. Bring potted plants indoors if nights get chilly in your area.

No-Humidity Humidity

While it doesn’t need the humid air craved by tropical plants, good air circulation is a must. Stagnant air encourages pests and disease. Let a fan provide a gentle breeze or open a window.

Potential Plant Pests & Problems

The main issue for Adenia globosa is overwatering, which can cause root rot or fungal diseases. Let the soil dry out fully to avoid these killers. Watch for common pests like mealybugs too and treat them right away.

Pruning Particulars

You don’t need to prune this low-maintenance plant unless you want to trim off any unsightly dead stems or leaves. Ouch – just be careful of those sharp thorns! Wear gloves since the sap can irritate skin.

New Pots for Growth

Adenia globosa is a slow-grower, so only repot every 2-3 years in spring. Size up by 2 inches if roots are coming out the drainage holes or circling the inner pot. Use a well-draining cactus potting mix.

Adenia globosa Propagation Methods

The easiest way to get new Adenia globosa plants is from seed. Just sow the seeds in spring and be patient – it can take years for new caudex stems to form! You can try stem cuttings too:

  1. Take 4-6 inch cuttings from a mature, healthy plant
  2. Remove any thorns and allow the cutting to dry for 1-2 days
  3. Dip the cut end in rooting hormone
  4. Plant cutting in well-draining soil or seed starting mix
  5. Keep warm and moderately moist until roots sprout in 4-8 weeks

With its alien caudex bulb and twisted spiky branches, there’s no plant weirder than the Adenia globosa! But once you get a hang of its easy care needs, this botanical oddity makes a fascinating, low-maintenance houseplant or landscape shrub. If you want to cultivate one of the strangest succulents around, the bizarre Adenia globosa is a must!
