If you’ve ever spotted a low-growing plant with smooth, reddish stems and small, fleshy leaves spreading across your flower beds or vegetable patch, chances are you’ve pulled it out without a second thought.
That plant is often common purslane (Portulaca oleracea), and while many gardeners treat it as a troublesome weed, it’s actually one of the most useful volunteer plants you can find.
From attracting pollinators to being edible and surprisingly drought-tolerant, purslane has been valued in gardens and kitchens around the world for centuries.
Before you reach for the trowel, here’s why you might want to let a little purslane stay.
1. It’s Perfectly Edible
Purslane has crisp, succulent leaves with a mild, slightly lemony flavour.
Young leaves and tender stems can be enjoyed:
- In salads.
- Stirred into soups.
- Added to sandwiches.
- Mixed into pesto.
- Lightly sautéed as a leafy vegetable.
Always harvest only from plants you’re certain you’ve identified correctly and that haven’t been exposed to pesticides or roadside pollution.
2. It Thrives During Hot, Dry Weather
While many plants struggle through summer heat, purslane keeps growing.
Its thick, fleshy leaves store water, allowing it to tolerate prolonged dry spells with very little care.
That’s one reason it appears so often during warm weather—it simply excels in conditions where many other plants slow down.
3. It Helps Cover Bare Soil
Purslane grows close to the ground, creating a natural living mulch.
When allowed to grow in suitable places, it can:
- Shade the soil.
- Reduce moisture loss.
- Help suppress some weed seedlings.
- Protect the surface from drying out.
Just be sure it isn’t competing with young vegetables or newly planted flowers.
4. Pollinators Appreciate the Flowers
Although tiny, purslane’s bright yellow flowers provide nectar for small pollinating insects.
The blooms usually open in bright sunshine and can attract:
- Small native bees.
- Hoverflies.
- Tiny beneficial insects.
Every nectar source helps create a more wildlife-friendly garden.
5. It’s Surprisingly Nutritious
Purslane has attracted attention because it contains a range of naturally occurring nutrients, including:
- Vitamin C.
- Vitamin A (as beta-carotene).
- Potassium.
- Magnesium.
- Plant-derived omega-3 fatty acids.
While it’s no miracle food, it can be a nutritious addition to a varied diet.
6. It Can Tell You Something About Your Soil
Like many volunteer plants, purslane tends to appear where conditions suit it.
It often grows in:
- Warm soil.
- Sunny locations.
- Well-drained beds.
- Disturbed ground.
Its presence isn’t necessarily a sign of poor soil—just that the conditions favour its growth.
7. It Works Well in Wildlife Gardens
A completely weed-free garden isn’t always the healthiest one.
Allowing a small patch of harmless volunteer plants like purslane in less formal areas can increase biodiversity by providing shelter and food for insects.
Balance is the key—keep it where it’s useful, remove it where it becomes a problem.
When You Should Remove It
Purslane isn’t suitable everywhere.
It’s best removed if it:
- Starts competing with young vegetable seedlings.
- Crowds slower-growing ornamental plants.
- Produces more seedlings than you want.
- Spreads into paths or paving joints.
Because it can self-seed readily, pulling unwanted plants before they flower and set seed helps keep it under control.
Be Careful With Identification
Before eating any wild-growing plant, make absolutely sure you’ve identified it correctly.
Purslane is sometimes confused with spurge (Euphorbia species), which has a similar low-growing habit but produces a milky white sap when broken and is not edible.
True purslane:
- Has smooth, succulent leaves.
- Has reddish stems.
- Does not produce milky sap.
- Produces small yellow flowers.
If you’re ever unsure, don’t eat it.
Final Thoughts
Purslane may arrive uninvited, but that doesn’t mean it’s unwelcome.
This humble volunteer plant offers edible leaves, drought tolerance, nectar for pollinators and useful ground cover—all while asking for almost nothing in return. Like many so-called weeds, its value depends on where it’s growing and how you choose to manage it.
Rather than removing every purslane plant on sight, consider leaving a small patch in a suitable corner of the garden. You might discover that one of the most overlooked plants is also one of the most useful.
