Kunzea jucunda is a shrub with a few erect main stems and many short side branches. It usually grows to a height of and is mostly
glabrous except for a few hairs around the flowers and youngest leaves. The leaves are glabrous, mostly elliptic in shape, about long and wide with a
petiole less than long. The flowers are arranged in heads of mostly two to four on the ends of the side branches. The flowers are surrounded by
bracts which are about long and wide, mostly glabrous except for a few hairs around the edges and by pairs of smaller
bracteoles. The
floral cup is about long and the five
sepals are lance-shaped, glabrous and about long. The five
petals are spatula-shaped to almost round, about long and pink to deep mauve. There are eighteen to twenty four
stamens in several rows in each flower. Flowering occurs mainly between August and October and is followed by fruit which are urn-shaped
capsules with five vertical ridges. This kunzea is similar to
K. affinis but is distinguished mainly by the mostly glabrous leaves and bracts. Where the ranges of the two species meet, hybrids often occur. ==Taxonomy and naming==
