Helianthella uniflora, Onehead Sunflower. Family Asteraceae. Very showy flower common in subalpine meadows. This beauty is the summer splendor over the high meadows on Mount Timpanogos. Millions and millions of these blossoms turn the whole landscape into yellow gold.
Tamarix ramosissima, Salt Cedar, Tamarisk. Family Tamaricaceae. An introduced invasive species common along waterways throughout the western region of the US. Introduced to the US early in the 20th century, Tamarix is thought to crowd out native species and compromise riparian environments. Nice flowers, but the shrubby trees are kinda messy when they get overgrown.
