The upper stems are covered in sticky hairs, and can reach up to 50 cm in height at maturity. The lower leaves are 5-10 cm in length. This plant will flower from June to as late as mid September; with flowers that are found individually at the end of stems with 5 petals that are either white or pink. Flowers only open up in the early evening and are very distinct, with green sepals that form a calyx with 5 distinct veins.
