I grew Farnsworth’s jewel flower (Streptanthus farnsworthianus) for the first time in 2021. Though the species is native to California, it is indeed a gem even here in Pennsylvania. It starts out as a clump of deeply cut green leaves, then sends up slender flowering stems that reach about 18 inches tall. Along those stems, there are small but charming, creamy white blooms that have purple calyces, along with broad bracts that start out green and gradually turn a dusty plum purple to rich violet, making a beautiful contrast to the pale blooms. Farnsworth’s jewel flower produces a really nice show for several weeks in early summer. It’s no in-your-face zinnia or sunflower, but if you enjoy growing uncommon annuals, it’s a neat oddity to try. It apparently grows in poor, dry soil in its native habitat, but give it a spot with good garden soil and enjoy watching it thrive. Full sun. Annual.
Harvested in late June and early July 2022. At least 15 seeds.
