Description and Ethnobotany
| Growth Form | It is a multi-trunked tree, or shrub with low spreading branches. |
| Foliage | Its alternate, stalked leaves are oblong to lanceolate in shape, densely-covered by silky hairs and appear silver in colour, 5-10 cm long. |
| Flowers | Its flowers are inconspicuous, greenish purple-white, free-blooming. |
| Fruits | Its fruits are aggregate fruits, reddish-brown in colour, small, resembling cone-like buttons. |
| Others - Plant Morphology | Can be planted singly as specimen tree in silver-themed gardens, or grown close together as informal or clipped hedge. Also suitable as bonsai. Drought and salt-tolerant, suitable for coastal or beachfront planting. Coastal trees tend to grow contorted trunks. Plants located far inland may be affected by sooty mould caused by sucking insects. Wood once used as high-quality charcoal in Florida, especially for smoking fish and meat dishes. Corky bark harvested commercially for high tannin content. |
| Habitat | It grows in coastal swamps of (along the edges of salt flats, rocklands, fresh and brackish marshes) in South Florida. |
| Cultivation | It can be propagated by seeds or stem-cuttings. |
| Etymology | Greek kono, cone, Greek karpos, fruit, referring to the cone-like fruits; Latin erectus, upright; Latin sericeus, silky, silky-hairy, referring to the silky hairs that cover the surfaces of the leaves. |
| Ethnobotanical Uses | Timber & Products ( Wood was once an important source of firewood and charcoal in Florida. Sometimes used in cabinet-making. Bark is high in tannin, can be harvested commercially.) |
