The official city flower of Yreka is the Yreka phlox ("Phlox hirsuta"). Most cultivated phlox, with the notable exception of "Phlox drummondii", are perennial. "Phlox paniculata" is grown largely for its showy fragrant flowers in high summer. Creeping phlox blooms in spring and produces long, spreading stems, which become woody with age. Alpine vegetation is low herbaceous, typified by "Phlox diffusa" and species of "Carex". Creeping phlox spreads rapidly and makes great ground cover. Phlox can be propagated from stem cuttings. Phlox are valued in the garden for their ability to attract butterflies. Phlox species are also a popular food source for groundhogs, rabbits and deer. T'Pol, Phlox, Archer, and Ensign Sato make a tour of the medical facility. Art begins a relationship with an insecure young woman named Phlox Lombardi. Soval, on "Avenger", then attacks, but Tucker disables Phlox and restores power. At the request of Dr. Phlox, Tucker agreed to undergo Vulcan neuropressure treatments with T'Pol.
