Genetics and seed type

The recorded lineage is Grapefruit x Blueberry. This parentage is specific to this catalogue profile; similarly named cultivars should not automatically be assumed to share the same lineage or characteristics.

Sweet Deep Grapefruit is classified as feminised seed. Feminised describes the listed seed type and is distinct from the cultivar’s reported indica phenotype, which refers to its descriptive classification.

Aroma and characteristics

Citrus and berry are the two documented sensory descriptors. Together, they suggest a fruit-centred profile combining a bright citrus character with a softer berry note. The supplied facts list these as flavours and do not provide a separate aroma description.
