Will Coreopsis grow well in soil that is constantly moist? I was given two of these plants " sun up" variety and the best spot for them visually in my garden would be in clay soil that is constantly moist and never dries out. Thank You

As above^^^ I grow both C. verticillata ' Zagreb' and C. grandiflora and both thrive on hot, dry, very well drained chalky soil

Many thanks to you both! From what you both have said I will plant it next to my Hyssop which has growing conditions ( soil and light) similar to what you've recommended.

Not from what I've read Loosestrife it likes dry to medium moisture, well-drained soil in full sun.
