Chamaebatia foliolosa, supposedly a member of the rose family, is a scent once sniffed is never forgotten.
Mountain Misery, it's common name, or Kit Kit Dizze, it's less common- common name, is the scent of the Sierra Nevada mountains. Deeply green and resinous with earthy tones typified by the breath-catching vapor of fresh cilantro.
I have no idea why it was given the name 'Mountain Misery'. Some cite old-timer's references that during the high summer season, getting the resin on your skin and clothes made one miserable based on the pungent scent it left behind. Or perhaps it was because the plant blooms with little flowers that closely resemble strawberry blossoms, and subsequently produces small reddish berries which are inedible, though not poisonous. I can imagine a hungry mountain man thinking he'd found a wild strawberry patch (though he'd have to be completely delusional, mind you) and biting into one of the small, dry, bitter, earth-worm flavored berries. Misery?
Mountain Misery is also a natural insect repellent, and it repels some animals too. After the rains begin in the Sierras, the resins wash off the plant and deer begin munching on them. Mountain Misery comprise approximately 30% of a deer's winter diet.
But it is the scent of Mountain Misery which captivates me. I grew up in these mountains, and this particular scent brings back many happy memories.
