If the idea of watering your garden plants often is not your cup of tea, you should consider drought-tolerant plants.
I’m not just talking about plants that can withstand a week without rain. I’m also thinking that “drought” means nobody remembered to water the plants for a day or so…or three. Ask the staff at your local nursery or home improvement garden center for drought tolerant plants – that’s the usual lingo used.
Portulaca, Moss Rose, Rose Moss
My all-time favorite plant that absolutely thrives on almost total neglect is the annual flower portulaca, which also goes by the name of moss rose, and sometimes by rose moss. I remember first seeing this flower in my grandmother’s garden when I was a little girl, and have loved it ever since.

I plant this every year in my garden and containers. It blooms all Summer into Fall (as long as there is warm sunshine), it spreads with more and more blooms as the Summer progresses, and it thrives in poorer soils. No need to fertilize this plant, and it isn’t bothered by any serious pests either.
Let me repeat: no need to fertilize this plant at all. In fact, if you do fertilize it? You might kill it. Seriously.
OK, didn’t mean to scare you, but a little fertilizer will encourage more green leaves than blooms. A lot of fertilizer will indeed kill the plants.
We have a strip of garden in front of our low-walled garden beds that gets super-hot in the Summer being next to our sidewalk going up to our front door. Portulaca has been the perfect solution for this spot.

The plants receive water whenever we run our lawn sprinklers or when it rains. Portulaca is a succulent, which means that it stores water in its leaves and stems to use when it gets a bit thirsty. Because portulaca’s root system is very shallow, too much water could actually drown the roots thus killing the plant.
Speaking of rain – Portulaca will close up during rain or during cloudy days, and sometimes at night too. This occurs more with the single-petal version than it does with the double-flower version.
Annual…but sort of a perennial too!
Another great thing about portulaca is that it nicely reseeds itself, but not invasively. For example, in this picture below, you can see our single-flowered portulaca which I planted in June with some of the double-flowered seedlings that sprouted up from last year’s planting. We love this!
Spot the seedlings!
It is easy to spot newly sprouted seedlings for two reasons. First, these seedlings don’t begin to sprout until mid-June, so you can happily weed away in the Spring without worrying that you might be pulling up any valuable (that’s what I think of these little guys) new plants. Secondly, when the seedlings do show up, you can tell them apart from other weeds right away because their tiny leaves immediately resemble their full-grown versions.

Single or Double? Try both!
The single-version portulaca plant is more of a groundcover, growing out (horizontally) rather than up (vertically). The height is a mere few inches, but the spread can be easily 14 inches or more.

The double-version (sometimes called semi-double) portulaca grows a bit more vertically, and the flowers resemble tiny roses with their double petals which appear to be very full and fluffy.

Both types come in a gorgeous array of Summer colors, and there are even some new hybrids that have veining within the flower petals too, such as the Peppermint Portulaca varieties.

Portulaca is the perfect choice for rock gardens, hot and dry spots, hanging baskets and containers. It thrives on neglect, and you’ll look like a professional gardener as the plants keep on blooming all Summer long into the Fall season!

Have your tried portulaca? Do you love it? Any preference on the single or double varieties?

Please note: As with many garden plants like azaleas, daylilies and begonias just to name a few, portulaca can be toxic to dogs and cats if swallowed. Please research your plants for toxicity if you have furry family members who enjoy being outside with you. The ASPCA has a great list here.
