This plant is a California native called Coreopsis gigantea. Quite pretty when it is in season. But when it goes into dormancy, you would think you have outrightly killed it. But be very patient, it is really just sleeping. So many times last summer, that I feel like I have killed it. But now it is slowly waking up. Sometimes, just got to know its culture, so knowing the natural dormancy times will help us continue caring for a seemingly dead looking plant. The best part for this plant when asleep, is to leave it alone, no water, no fertilizing...oftentimes it is hard not to water..so I keep this away from my other plants, so I do not accidentally kill it with love.
Photo last Apr 2014 when I first got it
Dormant, looks so dead during the dry warm days to summer
Finally, this winter, it is slowly waking up from its slumber...yey! Still alive!
