Source-derived summary

Plectranthus verticillatus (syn. Plectranthus nummularius), Swedish ivy, Swedish begonia or whorled plectranthus is a plant in the family Lamiaceae (Labiatae), genus Plectranthus native to southern Africa. Despite its common name, it is not close to the ivy family of the genus Hedera nor is it native to Sweden.

Description

The plant has aromatic glossy, green, round leaves, which show a deep purple color in the center sometimes and tend to trail, reaching a height of between 10 and 30 cm and extends around 60 cm. This deep purple can also be found on the plant stems and on the underside of leaves. The leaves, which are widely serrated, are fleshy and rounded between 64 and 90 mm, with purple and hairy undersides with reddish sessile glands.

The upright racemes appear white, pale violet or pale pink and can sprout sporadically throughout the year (but more typically in spring and late autumn), which form verticillasters of 2-4 flowers and 2–3 mm bracts. The fruits are 1 mm nuts, brown in colour and wrinkled.

The name "Swedish ivy" is deceptive: the plant is not thigmotropic (meaning it does not cling to walls with the roots when it grows), is not native to Sweden, and is not closely related to the genus of ivy (Hedera). Some variegated, silvery plants called Swedish ivy grown in pots and hanging baskets are Plectranthus oertendahlii from coastal river gorges of KwaZulu-Natal.

Editorial summary

The public source identifies “Plectranthus verticillatus” as species of plant. This brief keeps that definition visible, then builds a research path around Plectranthus, verticillatus and species.

Editorial reviewUseful for establishing the present vocabulary of the subject while preserving a route back to the evidence on which that vocabulary rests. The current 234-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. Its value is orientation rather than verdict, with Plectranthus, verticillatus and species providing the first useful test.
Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “Plectranthus verticillatus”, the useful work is to connect “species of plant” to the records capable of establishing context and consequence.

Evidence profile

The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Mar 10, 2026. The linked authority identifier is Q2296184. None of the 0 selected statements returned an explicit reference.

Critical limits

Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it
