Bulletproof landscape plants

When it comes to their growth, not all plants are the same. Some plants are fussy if the soil, climate, and care are not right. Others take a more relaxed approach and do their best no matter where, when, or how they were planted. These plants are considered ‘bulletproof’ and can be a starting point for a simple-care garden.

Bulletproof plants are immune to disease and pest problems. They also have a high tolerance for extreme soil conditions, such as dry and wet. They can also tolerate heat and cold. Bulletproof plants can also quickly establish strong roots, which is part and parcel of their survival strategy.

A plant that is too bulletproof can become a weed. You want to work in a garden and not become weedy. Choose plants that aren’t prolific, won’t spread by the rhizomes, and won’t become invasive.

Where to look

There are bulletproof plants in your area. You can find plants that survive in neglected gardens or thrive in harsh surroundings like a roundabout plant near a fence, footpath or car park.

If you cannot identify the plant, contact your local council or garden centre for assistance. Experts should be able to identify the species and genus, and the cultivar. You can also use state-of-the-art apps to identify plants.

One word of caution: Even bulletproof plants can take a hit when moving outside their comfort zone. Poorly drained soils, extremes in cold and heat, salt spray, and other factors can all take their toll. Poor planting and poor post-planting care can all lead to plant failure.
