Phacelia tanacetifolia Bentham is a multifaceted highly drought tolerant economic plant species with attractive blue colored inflorescence. The study aimed to optimize the best date length time to sow and harvest cv. Balo and Enton of the species commercially in hot humid continental climate. The day length during vegetative stages of plants sown on March 1, April 1 and May 1 ranged 12:01:15-13:54:50 h, 13:16:38-14:40:16 h, 14:19:55-15:00:23 h respectively. These genotypes had synchronization towards flowering with day length of 13:54:50 (on May 3)-15:00:01 (on June 8), 14:40:16 (on May 26)14:58:14 (on June 29) and 15:00:23 (on June 20)14:35:51 (on July 19). The vegetative, generative growth and corresponding floral yields performance of the genotypes decreased significantly with each delay in the sowing date. March sown plants had the best performance with outstanding yields. These plants had large plant canopy and high number of flowers suitable for gardens, hedges, and pot plants as well cut and vase flowers. April 1 and May 1 sown plants were comparatively low in quality in terms of plant canopy and size of flowers. Most of the 1 May sown plants had single shoots with lesser vegetative growth and decreased inflorescences quality. The result of the study indicated that the plants could serve as a cost-effective potential source for use as cover crop, and in landscaping at if sown on 1st March as they have long vegetative and flowering period of over 65 days without adverse negative effects on the environment.
