Callitroideae is a subfamily of Cupressaceae encompassing some of the southern hemisphere’s most botanically distinctive conifers. The Australian members — including Callitris, Actinostrobus and Diselma — are among the continent’s most drought-adapted conifers. South American representatives (Austrocedrus, Fitzroya, Libocedrus, Pilgerodendron) include trees of ancient lineage and exceptional rarity. This collection sits at the intersection of southern hemisphere botanical heritage and collector horticulture.
