Isopogon formosus is an erect or spreading shrub 1.5-2 m tall. The leaves are divided and crowded along the stem. The divided segments are a narrow, grooved, terete (cylindrical) and are about 5 cm in length. The young growth is silky-hairy, often reddish and is a particularly attractive feature of the plant. The flowers are a rose-pink to pale pink in colour and are clustered together to form a flower head at the ends of branches.
A possible alternate way for it to be grown is to grow it in a pot as the particular conditions it requires can be satisfied readily and be more easily monitored. It is well worth attempting to grow, as it is a spectacular plant that can be used as a feature in the garden all year round.
