Coreopsis
We have some Coreopsis in the bed at the back of our yard. That bed actually needs a bit of work, but this is a fairly reliable little perennial that I’d hate to lose to any renovation. It’s a very cheery orange color and although later in the summer that would be drowned out by all the black-eyed Susans, at this time of year, before even the day lilies have started to bloom, it’s quite welcome. We’ve had other Coreopsis plants but they haven’t done as well as this one with large petaled flowers and less feathery foliage. It’s quite happy to be mostly neglected, which is sort of what it takes in that garden.
