Ceropegia simoneae aka Dragon Lizard Plant

Ceropegia simoneae is a challenging plant to grow, best suited for experienced succulent growers. It is highly sensitive to overwatering and rot, requiring careful attention to watering schedules and soil drainage. The species also demands consistent warmth (never below 10°C) and cannot tolerate cold drafts or frost. Nursery-bred specimens tend to be somewhat more resilient than wild-collected plants, but this remains a demanding species overall.

Ceropegia simoneae is a compact, slow-growing succulent that develops from a tuberous rootstock. The main quadrangular vegetative stems are typically short and stout, giving the plant a small, sculptural form. When the plant produces its flowering stems, these are distinctly different — thin, cylindrical, and twining — and can extend further as they seek support. Overall, this is a small species well-suited to pot culture, requiring repotting only every 3–4 years.

Ceropegia simoneae requires warm conditions year-round. The ideal growing temperature is around 25°C (77°F), and it should never be exposed to temperatures below 10°C (50°F). In winter, maintain a minimum of 10–15°C (50–59°F). Avoid cold drafts and sudden temperature drops, as the plant originates from the hot, arid climate of southern Madagascar.

The flowers of Ceropegia simoneae are extraordinary and among the most remarkable in the genus. Each bloom is 6–7 cm long with a grey-green corolla blotched with purple. The flower has an inversely bulbous base (dark wine-red inside), a narrow middle section, and an opening that widens to about 8 mm. The corolla lobes are 2–2.5 cm long, narrowly linear, folded back, and covered in dense purple hairs that spiral outward — creating a dramatic feathery appearance, especially in bud. Flowering occurs mainly in autumn and winter.

Ceropegia simoneae uses a sophisticated pitfall-trap pollination strategy shared by all members of the genus. The flowers emit chemical signals mimicking injured arthropods to lure small kleptoparasitic flies (primarily from the families Milichiidae and Chloropidae) into the corolla tube. Once inside, downward-pointing hairs trap the flies in the basal chamber where they are coated with pollen. After roughly a day, the hairs wilt and release the pollen-laden flies, which may then visit another flower and complete pollination.

Ceropegia simoneae can be propagated by stem cuttings or tuber division. Rooting hormone can improve success rates. The plant sometimes develops small tuberous growths on its branches — these can be gently detached in spring and planted in a warm, humid substrate to establish new plants.

The most significant threat to Ceropegia simoneae is root and stem rot from overwatering — the species is extremely susceptible to fungal rot in wet conditions. Common insect pests include mealybugs, spider mites, and thrips. Giromagi notes that Ceropegia species in general are 'sensitive to rots and also to many diseases,' though nursery-bred cultivars tend to be more resistant. Good air circulation and careful watering are the best preventive measures.

Ceropegia simoneae is a slow grower that only needs repotting every 3–4 years. The best time to repot is in spring when the plant enters its active growth phase. Use a well-draining succulent or cactus mix with added perlite to prevent moisture retention around the tuber. Choose a pot only slightly larger than the current one, as excess soil volume retains moisture and increases the risk of rot.

Ceropegia simoneae can only grow outdoors year-round in warm, frost-free climates — roughly USDA zones 10–11. Even in these zones, it needs a sheltered position with protection from rain and intense direct sun. In cooler climates, it is best grown in a pot that can be moved indoors before temperatures drop below 10°C (50°F). Outdoor plants should be placed in a partially shaded spot with excellent drainage to prevent waterlogging.

The flowers of Ceropegia simoneae produce scent, but it is not designed to appeal to humans. Like other Ceropegia species, the flowers emit chemical compounds that mimic the odor of injured arthropods, specifically to attract small kleptoparasitic flies for pollination. This scent is emitted from specialized tissues called osmophores on the corolla tips. The scent is generally subtle and may not be noticeable to most people at typical indoor distances.

Drooping or softening stems in Ceropegia simoneae most commonly indicate overwatering and the onset of root or stem rot — the most frequent killer of this species. Check the base of the stems and tuber for mushy, discolored tissue. If rot is present, remove affected parts, let the cuts dry, and repot in completely dry soil. Less commonly, drooping can result from underwatering (the stems will appear shriveled rather than mushy) or cold stress from temperatures below 10°C.

Dragon Lizard Plant’s native range is Africa to Southern Asia and Australia.

Dragon Lizard Plant does best in dry soil and should only be watered sparingly.

Dragon Lizard Plant loves a well-draining soil. Perlite and vermiculite help with drainage, while coco coir adds organic matter, so a good potting soil mix will have all three. You can improve store-bought soil by adding some perlite to it.

To ensure optimal growth, the Dragon Lizard Plant prefers bright diffused light for 6-8 hours each day. Insufficient light can result in slow growth and leaf drop, so it's important to find a well-lit location for this plant. Place it near a window, within a distance of 1 meter (3 feet), to enhance its potential for thriving.

The Dragon Lizard Plant does not necessitate supplementary humidity. Plants primarily absorb water through their roots, rather than their leaves. Hence, the most effective way to supply humidity to your plants is by watering the soil.

The Dragon Lizard Plant should be transferred to a new pot once it has increased in size two-fold, or on an annual basis, whichever occurs earlier. Replacing the soil with fresh potting soil containing all the necessary nutrients, is sufficient enough to support the growth of the plant, thus avoiding the need to use fertilizer. It's important to note that plants derive their energy from the sun and not fertilizer.

Ploi does not possess verified information regarding the toxicity of this particular plant. In the event that you, a member of your family, or a pet ingests plant material with an unclear toxicity level, it is highly recommended to seek the advice of a medical professional.

During the cold period, it is common for Dragon Lizard Plant to go dormant and their growth may slow down, so waterings should be spaced out more during this period.
