I've got 3 myrtus communis compacta that are looking for new homes, as I am putting in a new veggie bed.

Lots of other stuff here like rosemary or rock rose and some lavender you could probably divide. Please come up and go shopping in my yard. The place was landscaped about 5 years ago, and many plants have are starting to crowd each other out and some are just in the wrong place to begin with.

Am in sunland/tujunga.

I doubt the Lantana is dead. Mine gets frosted everyyear and looks dead also. Give it a couple weeks before tearing it out.

I have several salvias, bush germander teucrium fruticana Azureum, sweet pea bushes, goodwin creek lavender, little john dwarf bottlebrush, orchid rockroses, lavatera.
All have survived colder winters in previous years and survive on 5 minutes of water twice a week.

Lantana will sometimes live and sometimes not live, it really depends on how big it is and how cold it gets. If you have a huge plant it can live, small ones often don't live.
