Garden Phlox and Live Forever

After a very dry winter, our plants aren't thriving. Other years the garden phlox has been elbow high but not this year. And now today is the day to plant coleus in some pots on the porch. And later - The temperature has been falling since mid morning with northerly winds. We have put off the planting until tomorrow. With a forecast of middle 30's tonight, we don't want any frosty coleus wilting on the porch.
