Perennial. It grows up to 600 mm in height. It has many slender erect stems which branch freely, emerging from a woody taproot. Stems have numerous, narrow, serrated leaves which are denser near the base of the stem. The leaves are fresh green and shiny. The stems grow lanky as more and more flowers develop at the tips. The flowers resemble little snapdragon flowers, with two lips and a spur. They are dusty-pink or mauve or even whiter in colour and decorated with bright yellow protuberances in the throat. The mauve nemesia flowers mostly at the beginning of spring (September-October), but the flowering season can extend through summer to autumn. The seeds are produced in flat capsules which are dry and whitish to yellow-brown in colour.
