12 Ceropegia Varieties Most Collectors Can’t Tell Apart — 4 ID Features That Separate Them
Can’t tell Silver Glory from standard C. woodii? The 4-feature ID system that separates all 12 varieties — from garden center find to collector grade.
Pick up a standard String of Hearts (Ceropegia woodii) at a garden center, then find a ‘Silver Glory’ at a specialty nursery six months later, and you may not realize you’ve bought the same species in two different forms. The Ceropegia genus contains over 180 species — and while only about a dozen circulate in the houseplant trade, the differences between them are genuinely easy to miss until you know what to look for.
The confusion is compounded by overlapping trade names. What retailers call “String of Spades,” “Heartless,” and “Durban” are often the same plant under three labels. “String of Needles” is a different species entirely, with a disputed toxicity profile that C. woodii doesn’t share. And ‘Silver Glory’ looks fundamentally different from standard woodii once you check the right feature — which turns out to be leaf shape, not the color everyone focuses on.
This guide covers 12 Ceropegia varieties across three availability tiers, from the plant found at any big-box store to the ones that surface once or twice a year through specialist growers. Before the profiles, four ID features form the framework that makes distinguishing them fast and reliable. For a full growing guide covering soil, watering, and repotting schedules, see the complete String of Hearts growing guide.
Four Features That Identify Any Ceropegia Variety
All 12 varieties here can be separated by working through four features in sequence. You only need to find the first feature that differs to reach a confident ID.
1. Leaf silhouette. Standard C. woodii has a notch at the base of each leaf — those two lobes are what create the heart shape. String of Spades cultivars (‘Heartless’, ‘Durban’) have a more pointed base with shallower lobes, closer to a spade suit card. String of Arrows goes further: nearly triangular leaves with a sharp apical point and almost no basal notch. String of Needles (C. debilis) is completely linear — leaves are narrow and up to 2 inches long with no appreciable width. Silver Glory breaks the other direction with a rounded, kidney-shaped base rather than a pointed tip.
2. Variegation and coloration pattern. Standard C. woodii has dark green leaves with silver mottling covering roughly 30–40% of the leaf surface. Silver Glory pushes that coverage to 80% or more, leaving only a thin green edge line. Variegated woodii (f. variegata) shows cream or pink margins rather than an internal silver wash — the effect is a contrasting border, not an overall lightening. Pearl Moon adds a pinky-purple cast to the whole leaf underside. Orange River stays nearly uniformly green until stress triggers an orange-bronze flush from beneath.
3. Stem and leaf underside pigment. Anthocyanin production creates the burgundy stems and purple leaf undersides that many varieties share. The Spades group — ‘Heartless’, String of Arrows, and ‘Orange River’ — produces little to no anthocyanin, leaving stems light pink or pale green. If you’re holding a trailing Ceropegia with almost no red or purple tint anywhere on the stems, you’re looking at a Spades-type cultivar.
4. Succulence type. All C. woodii cultivars store water in leaf tissue and in the tubers that develop along the stems — the small round “beads” that give the plant its alternative name, Rosary Vine. C. haygarthii (Lantern Flower) is the exception in this list: it stores water in its stems rather than its leaves, making the shoots noticeably thicker and fleshier than any woodii cultivar. That physical difference is the fastest way to separate it from everything else here.
Tier 1 — Three Varieties at Any Garden Center
These three are reliably stocked at big-box garden centers, most independent nurseries, and mainstream online retailers throughout the year.
1. Standard Ceropegia woodii
The benchmark variety. Stems reach 3 feet in containers and can exceed 12 feet in native South African habitat, where the plant scrambles across rocks in poor soil with partial light blockage. Leaves are dark green with distinct silver mottling, 1–2 cm wide and long, with purple undersides. Stems are burgundy. A caudex — a swollen woody base — develops over time and functions as a water reservoir, letting the plant survive several weeks without irrigation.
Flowers appear primarily in summer and fall but can occur sporadically year-round. The structure is botanically distinctive: a tubular corolla with waxy downward-pointing hairs traps fly pollinators until the hairs wither and the insect escapes carrying pollen. The genus name Ceropegia derives from the Greek for “waxy fountain,” referencing this flower form. Seeds are flat with pappus structures for wind dispersal — the same mechanism as other members of the milkweed subfamily Asclepiadoideae, which includes hoyas.
This is the fastest-growing and most forgiving variety for beginners. In a west- or south-facing window with a cactus mix, it establishes quickly and throws out long cascades within a single growing season.
2. C. woodii f. variegata (Variegated String of Hearts)
The same species as standard woodii, with a difference in pigment expression at the leaf margins. Leaves show cream or white margins in lower light; in brighter conditions, those margins develop pink tones. The intensification happens because light triggers anthocyanin production in the variegated marginal tissue — the same pigment pathway that creates burgundy stems and purple undersides in the standard variety. In practice, this means the plant’s pink coloring is a direct readout of how much light it’s receiving.
The practical consequence: this variety needs more light than standard woodii to maintain its variegation. In a dim north-facing window, the margins revert toward plain green. Once a leaf loses its variegation, that leaf won’t recover — but new growth produced in brighter conditions will show full coloration.
Growth rate is slower than standard woodii; cuttings root more slowly, and a full cascade takes longer to develop. This variety is also sold under the name ‘Lady Heart’, particularly in Asian plant markets — the RHS accepts Lady Heart as a synonym of C. woodii f. variegata.
3. C. woodii ‘Silver Glory’
The misidentification seen most often at plant swaps: growers assume Silver Glory is a heavily variegated version of C. woodii f. variegata. The correction is the leaf shape. Silver Glory’s leaves are kidney-shaped — rounded at the base with almost no pointed tip — while standard woodii and variegata both end in a gentle point. Once you know to check the leaf silhouette first, the distinction is immediate and reliable.
Silver coverage is much higher than standard woodii: 80% or more of the leaf surface is silver-grey, with only a thin dark green line along the outer edge. Undersides are purple and intensify noticeably in bright light. The NC State Extension Plant Toolbox describes the leaves as “apple-shaped” with “dark green lines” — a useful shorthand. Care is identical to standard woodii, though the heavy silver coverage typically results in a marginally slower growth rate.
Tier 2 — Four Specialty Nursery Finds
These four turn up at specialist houseplant retailers, smaller independent nurseries, and online specialist growers. Availability is inconsistent — you may see them regularly one season and then not for months.
4. C. woodii ‘Heartless’ (String of Spades / ‘Durban’)
The naming around this variety is genuinely messy. Three trade names — ‘Heartless’, ‘String of Spades’, and ‘Durban’ — circulate in the market, and while some sources treat them as identical, others distinguish subtle differences in leaf pattern between the three. What they share: leaves more pointed than standard woodii with shallower basal lobes, light green to pale grey-green coloration, and almost no burgundy in the stems or undersides.
NC State Extension lists ‘Heartless’ as having “bright green” leaves with “pink underside,” while some UK retailers describe ‘Durban’ as having silver markings on the upper leaf surface with pink-and-silver coloring that brightens under sun. The simplest practical approach: if you see a C. woodii with spade-shaped leaves and pale stems, it belongs to this group regardless of the label.
5. C. woodii ‘String of Arrows’
The most angular of the woodii cultivars. Leaves are nearly triangular with a sharp apical point and minimal basal notch — the shape reads more like an arrowhead than a heart. The NC State Plant Toolbox describes the foliage as “lime green and silver pointed” with pink blooms. Stems stay light pink with little burgundy pigmentation, consistent with the broader Spades group’s low anthocyanin production.
String of Arrows is more regularly available online than many Tier 2 varieties, though less commonly stocked than the basic Spades group. Care requirements are identical to standard woodii: bright indirect light, full dry-down between waterings, and a fast-draining mix.
6. C. woodii ‘Orange River’
Named for the Orange River that runs through part of its native South African range, this cultivar distinguishes itself through its stress response. In standard conditions, leaves are light green and nearly uniform in color. Under bright light or mild drought stress — slightly dry soil, a position within 2 feet of a south or west window — the leaves develop a bronze-orange blush that makes the plant striking. This is one of the few houseplant varieties where intentionally stressing the plant produces a better ornamental result.
Leaf shape is more pointed than standard woodii, closer to the Spades group. Growth rate is fast — reportedly comparable to or faster than standard woodii. Availability has improved since 2023 as more specialist growers began stocking it, though it remains less consistent than Tier 1 varieties.

Taxonomically, String of Needles is a separate species: C. debilis, sometimes classified as C. linearis subsp. debilis. The distinction matters for one practical reason: while C. woodii is widely reported as non-toxic to cats and dogs, C. debilis carries a disputed classification — some databases list it as non-toxic, while others note it may cause gastrointestinal symptoms if ingested. Until that’s clarified, treat it with more caution around pets than you would standard woodii. If concerned about any ingestion, contact ASPCA Poison Control at (888) 426-4435.
Identification is straightforward: leaves are narrow and linear, up to 2 inches long and only a few millimeters wide — completely unlike any C. woodii leaf shape. The overall appearance is wiry rather than fleshy. Growth is fast; String of Needles cascades quickly and makes an effective hanging basket plant. It requires the same well-draining soil and drought-tolerant watering as woodii, with the same temperature minimum of 60°F.

Tier 3 — Five Collector Varieties
These five are sold by specialist growers, often in limited quantities. Expect to search online, join plant-swap communities, or sign up for waitlists at specialist nurseries. Availability can be seasonal and unpredictable.
8. C. woodii ‘String of Daggers’
String of Daggers has elongated, oval-to-lanceolate leaves with dark green surfaces and silver veining — longer than hearts but without the sharp triangle point of String of Arrows. The overall hanging effect is closer to a narrow pendant than the compact hearts of standard woodii. Stems are burgundy. Care requirements mirror standard woodii exactly.
Availability is inconsistent; it appears in online specialist shops but is not reliably stocked. If you find it alongside String of Arrows at the same retailer, the two are easy to distinguish: Arrows has an angled, triangular silhouette, while Daggers stays wider and more oval throughout its length.
9. C. woodii ‘Pearl Moon’ (Pink Edge)
Pearl Moon is frequently mislabeled as standard Variegated String of Hearts at first glance. The distinguishing feature: in Pearl Moon, the entire leaf underside takes on a pinky-purple cast, and the margin coloration extends further inward to give a fuller pink effect than the edge-only appearance of f. variegata. Under bright light, the pink effect intensifies considerably.
Growth is noticeably slow — slower than Variegated woodii, which is already slower than the standard. A south or west-facing window is essential to maintain full coloration; in a north or east window, the pink fades toward plain green within a few months. This variety circulates under multiple names including ‘Pink Edge’ and, in Asian plant markets, as a premium form sold at a significant price premium over standard Variegated.
10. C. woodii ‘Mini Star’
Mini Star is small-leaved and, depending on the source, may be the same plant as ‘Heartless’ or a genuinely distinct form with even smaller, lighter green leaves. Some retailers list it as a synonym for Heartless; others treat it as a separate cultivar. The practical ID test: if Mini Star leaves are measurably smaller than a Heartless specimen at the same growth stage, you likely have a distinct form. If leaf size is the same, you probably have the same plant with a different label.
What is consistent across sources: lighter green coloration than standard woodii, absence of burgundy stem pigmentation, and a small leaf size that makes the cascading effect particularly fine and delicate compared to the rest of the genus. Availability is rare; this is more likely to appear through plant swaps than at any nursery.
11. C. sandersonii (Parachute Plant)
Ceropegia sandersonii earns its common name from its flowers: the corolla lobes are fused at their tips, creating a dome-shaped structure over the flower tube that resembles an inverted parachute or umbrella. This is a dramatically different flower form from C. woodii‘s lantern-shaped blooms, and it’s the main reason collectors seek it out.
The plant itself is a climbing succulent with larger, darker green leaves than C. woodii — more oval than heart-shaped and fully green with no silver mottling. It grows more vigorously as a climber than as a trailer, so it benefits from a small trellis or moss pole rather than a hanging basket. Native to South Africa’s coastal regions, it tolerates slightly higher humidity than standard woodii.
For C. woodii growers looking to explore the broader genus, C. sandersonii is the logical next step — similar care, different growth habit, and a flower form unlike almost anything else in the average houseplant collection.
12. C. haygarthii (Lantern Flower)
The most structurally distinctive variety in this list: C. haygarthii is a stem succulent, storing water in its thick, bright green shoots rather than in leaf tissue or stem tubers. The shoots themselves are noticeably fleshy compared to C. woodii‘s slender trailing stems — running the fourth ID feature (succulence type) immediately distinguishes it from everything else here.
Flowers are creamy white with red spotting and a distinctive elongated tube with twisted petal tips — a form that retains pollinators longer than C. woodii‘s structure. Common names include “lantern flower,” “parasol flower,” and “parachute flower” — the last being shared with C. sandersonii, which causes occasional market confusion between the two species.
Native to South Africa’s Cape Province, C. haygarthii requires the same essentials as C. woodii — bright light, excellent drainage, and complete soil dry-down between waterings — but circulates primarily among succulent collectors and through specialist online growers. It represents the far edge of what most people recognize as a “String of Hearts” plant, but the care relationship to everything else in this guide is direct.
Care That Works Across All 12 Varieties
Despite their visual differences, all 12 varieties share the same core care framework.
Light. All Ceropegia need bright indirect light — a west- or east-facing window, or a south window with the plant positioned 2–3 feet back. Standard C. woodii manages in lower light and will simply grow more slowly and lose color depth. Variegated, Silver Glory, Pearl Moon, and Orange River all require brighter conditions to maintain their characteristic coloration: in low light, variegated margins fade, Silver Glory grays out, and Orange River reverts to plain green. For display ideas that work in different light conditions, see String of Hearts display ideas.
Watering. Allow soil to dry completely between waterings — the caudex and leaf tissue store enough moisture to tolerate two to three weeks without water, but sustained moisture causes root and stem rot quickly. This applies equally to C. haygarthii, despite its stem-succulent structure. Reduce frequency further in winter during the plant’s rest period.
Soil. A commercial cactus and succulent mix, or standard potting mix amended with 25–40% perlite. Drainage matters more than nutrient content for this genus.
Temperature. Keep above 60°F year-round. All 12 varieties are frost-tender; outdoors, they are hardy only in USDA zones 10–12. The RHS rates standard C. woodii as H1C (minimum 5–10°C), which corresponds to zones 11–12 for year-round outdoor cultivation.
Propagation. For all C. woodii cultivars, the simplest method is pressing an aerial tuber — still attached to the vine — into moist cactus mix in a second pot. Once rooted and showing new growth (weeks to several months), cut it free from the parent. Stem cuttings root more reliably with gentle bottom heat. For step-by-step instructions across methods, see the full propagation guide.
Pet safety. C. woodii and its cultivars are widely reported as non-toxic to cats and dogs — a meaningful advantage over many popular trailing plants. C. debilis (String of Needles) carries an ambiguous classification and should be treated with caution around pets. For any concern about ingestion, contact ASPCA Poison Control at (888) 426-4435.
