I planted a standard lantana, as last year and they were beautiful. This year they look totally dead, although there are a couple of green shoots on two of them but on the end of one branch.

Lantana do require warm temperatures, so they may be slow to get started in the spring. You could give it a light fertilizer and just have a little patience! Good luck.
