Flour B/L Fig is a caprifig variety from Australia, introduced by Robin Oster of Fighunter Downunder, that produces notably generous yields across medium and large fruit sizes. This unique male fig maintains its characteristic green skin at maturity and thrives in full sun with moderate growth, making it a distinctive addition to warm-climate gardens. As a caprifig, it plays a specialized role in fig ecology, housing the wasps essential to pollination cycles and producing viable pollen in its Profichi generation.

Flour B/L Fig produces exceptional yields with impressively large internal cavities that attract and support the wasp populations critical to fig pollination. The green skin persists throughout maturity, giving it a distinctive appearance among fig varieties. Its role as a caprifig with viable pollen makes it functionally important for anyone serious about growing multiple fig varieties.
As a caprifig, Flour B/L Fig is not grown for direct eating but serves a critical ecological and breeding function. It produces pollen and provides habitat for fig wasps (Blastophaga psenes), which are essential for pollinating edible female fig varieties through a mutualistic relationship. For gardeners with multiple fig trees, especially those in regions with limited natural wasp populations, caprifigs like this one support fruit set and seed development across the broader fig collection.

Prune Flour B/L Fig to maintain an open, airy canopy that supports good air circulation and the movement of pollinating wasps. Light pruning in late winter or early spring helps shape the tree without excessive stress. Remove any dead or crossing branches, but avoid heavy cutting that disrupts fruiting cycles.

“Flour B/L Fig hails from Australia, where it was introduced by Robin Oster, the collector and breeder behind Fighunter Downunder. As a caprifig variety, it represents a specific, sometimes overlooked category of fig cultivation: male trees that produce pollen and house the fig wasps necessary for seed development in edible female figs. Oster's work preserving and introducing Australian caprifigs has made rare genetic diversity accessible to home and commercial growers.”
