A shrub up to 5 feet tall with a profusion of bright yellow flowers, the petals of which are unusually in a circle like a lit gas-stove ring, albeit one with a yellow flame rather than blue.

The leaves are greyish green in opposite pairs.

Bright yellow petals in a ring atop long stems. The petals drop off the innermost sepal tubes first, leaving the green pentagonally star-shaped sepal tubes visible in the centre.

A flower emerges from every sepal tube, of which there are many. Each flower consists of two petals, one folded over the other in a hood.

The construction of each flower from a lower lip and a long hood over-topping the lip is discernible. The greyish green leaves are wavy and have light-green edges and a pronounced network of veins. Note the square-section stems, covered in downy white hairs on the flats but not on the edges.

Occasionally, the flower forms a candelabra of rings one upon the other like a cascaded chandelier.

The leaves are mostly bluntly rounded rather than having a pointed end.

The rough texture of the leaves made by the network of veins and the hairy pale green rim. the stems are also pale green on account of their downy white hairs.

The rear of the leaves has prominent veins and is covered in downy white hairs.


Easily confused with : Turkish Sage but Turkish Sage has greener leaves that are pointed rather than rounded at the ends.

Not to be confused with: Sage (Salvia officinalis) which although it belongs to the same Dead-Nettle Family, is actually in a different Genera: Salvia as opposed to the Phlomis of Jerusalem Sage.

Uniquely identifiable characteristics

Distinguishing Feature (for the Genus Phlomis): The ring of radially-arranged yellow flowers looking like a gas ring.

Jerusalem Sage has the propensity to grow another whorl of flowers atop an already existing top-most whorl, rather like a candelabra. Of course, many (but not all) Dead-Nettle Family plants have chandelier-like whorls of flowers up a continuous and un-broken stem, but the chandeliers in Wild Basil are different: they are not on a part of the same stem, but on a new stem grown from somewhere near the middle of the existing topmost whorl. Turkish Sage and Wild Basil also exhibit this behaviour. The separate tiered stems are often thinner than those below them; and the corresponding whorls not as large: much more like a (albeit upside-down) chandelier.

Inhabits sheltered woods and scrub; prefers full sun exposure. More easily found in a park or garden. Very fast growing, reaches up to 5 feet tall.

The flowers are typical of the Dead-Nettle Family: two petalled, but most unusually they are in a circle formation akin to a gas ring.
