The outer side of the leaves are covered with distinctive tiny speckled "asperous" tubercles which (unlike Astroloba bullulata) are the same colour as the leaf.

It produces upright sparse inflorescences of creamy-white flowers during the dry summer (October to February), that are sometimes slightly pink or green.

The resulting hybrids are usually far larger, stockier and more erect than normal A. corrugata.

However this might also merely be the result of genes descending from distant past Tulista pumila admixture.

It hybridises naturally with its neighbour species to the east, Astroloba spirella.
