Peterson’s Picks: Plants with Power

Mark Peterson

Does your landscape lineup lack the strength to survive fickle forecasts and plant pests? Have no fear — Peterson’s Picks will give your garden superhero standing.

It’s no secret San Antonio’s climate can be challenging for gardeners, particularly if your landscape lineup lacks the flora fighters that can survive fickle forecasts and plant pests.

Enter my top plant selections — Peterson’s Picks, if you will — in six categories for our surrounding region. These selections are based on my nearly 40 years of landscape experience here in South Texas and three specific criteria: low maintenance, drought tolerance and pest tolerance.

Without further ado, here are my recommendations for a landscape with superhero standing.

  1. Ajuga (Ajuga reptans): shade; purple flowers; not deer-resistant.
  2. Creeping germander (Teucrium canadense): sun; small purple flowers; drought-tolerant and deer-resistant.
  3. Dwarf plumbago (Ceratostigma plumbaginoides): aka leadwort; partial shade; electric blue flowers; spreads.
  4. Frogfruit (Phyla nodiflora): native; partial shade; spreads; deer-resistant.
  5. Purple Heart (Setcreasea pallid): native, sun or shade; spreads; deer-resistant.
