Lupine plants comprising a homozygous recessive allele that produces a year round flowering characteristic (or year round flowering phenotype or trait) are disclosed. One embodiment relates to the seeds of said year round flowering lupine plants, to the plants of said year round flowering lupine plants, to plant parts of said year round flowering lupine plants, and to methods for producing a lupine plant produced by crossing said year round flowering lupine plant with itself or with another lupine plant. Another embodiment also relates to methods for producing a lupine plant having a year round flowering characteristic (or year round flowering phenotype or trait) and to the year round flowering lupine plants and plant parts produced by those methods. Another embodiment relates to producing interspecific lupine plants having a year round flowering characteristic.
