The densely woolly leaves of Helichrysum moeserianum are narrowly paddle-shaped and alternate. Leaf size diminishes higher up on the plant. Spaced leaves are also found up the flower stalks that grow from the erect stem-tips. Leaf dimensions are 15 mm to 30 mm by 3 mm to 5 mm.
The small, bright yellow flowerheads grow in crowded, flat-topped corymb-shaped clusters above the foliage. Each bell-shaped flowerhead is surrounded by about five rows of imbricately overlapping bracts that spread at their tips around the dense bunch of disc florets. Flowering happens from late winter through summer (Manning 2007; Bond and Goldblatt, 1984; iSpot; http://keys.lucidcentral.org).
