Introduction to Edible Spekboom
Portulacaria afra, known by many names including spekboom, elephant bush, and dwarf jade, is an incredibly resilient and versatile succulent. While it is celebrated globally for its carbon-storing capabilities and low-maintenance care, its edible properties are less widely known outside of its native Southern Africa. The succulent, plump leaves offer a zesty, lemon-like flavor that can add a unique twist to many dishes. However, as with any foraged food, proper identification and preparation are critical to a safe and enjoyable experience.
Identifying Your Portulacaria afra
Before you begin, you must be certain you are harvesting the correct plant. Portulacaria afra is often confused with the toxic Crassula ovata or jade plant, which can cause illness if ingested.
- Leaves: Look for small, rounded, glossy green leaves. They are fleshy and grow in opposite pairs on the stems. Green-leaved varieties are preferred for eating; avoid variegated types, as their taste can be bitter.
- Stems: The stems start out red or reddish-brown when young and become gray and woody with age. The stems of Crassula ovata are thicker and do not have the same red hue.
- Growth Habit: P. afra is a multi-branched shrub, whereas the leaves of a true jade plant (Crassula ovata) have a waxier appearance and are more widely spaced.
Harvesting and Preparing Spekboom Leaves
How to Harvest
When harvesting, select healthy, plump, green leaves from a mature, pesticide-free plant. Use clean shears or simply pinch off the leaves with your fingers. Harvesting from young plants or taking too many leaves at once can stress the plant and inhibit its growth.
Cleaning and Storage
Thoroughly washing the leaves is essential, especially if they are from an outdoor plant where they could be exposed to dust, pollutants, or pesticides. Soak the leaves in a bowl of cool water, then rinse them under a gentle stream of running water. Pat them dry with a paper towel before use. To store, keep the washed and dried leaves in an airtight container in the refrigerator for up to a week.
Important Warning: Quantity Matters
While P. afra is non-toxic, excessive consumption can lead to mild gastrointestinal discomfort due to the plant's natural acidity and oxalate content. Start with small quantities to gauge your body's reaction and always use it as an ingredient or garnish, not a dietary staple.
Culinary Applications and Recipes
The sour, tangy flavor of spekboom leaves makes them a fantastic addition to a variety of dishes. Here are some popular ways to incorporate them into your cooking.
- Fresh in salads: Sprinkle freshly washed leaves over a salad for a juicy, citrusy burst. They pair well with ingredients like tomatoes, chickpeas, and feta cheese.
- Soups and stews: Add a small handful of spekboom leaves to soups and stews for a lemony flavor. They can be added near the end of the cooking process to preserve their texture.
- Sauces and dressings: Chop the leaves finely and mix them into dressings, like a simple vinaigrette, or stir them into sauces to add a tangy, fresh component.
- Pickles: Spekboom leaves can be pickled to create a tart and crunchy condiment, a practice developed to make the ingredient more marketable and long-lasting.

The Health and Ecosystem Benefits
Beyond its unique flavor, P. afra is recognized for a host of other benefits. The high vitamin C content provides an antioxidant boost, and traditional uses include soothing sore throats and mouth infections by chewing the leaves. Crushed leaves were historically applied to blisters and calluses for relief. The plant is also known for its incredible ability to absorb carbon from the atmosphere, making it a valuable contributor to combating climate change. Its water-wise nature and low maintenance needs make it an accessible and sustainable choice for both gardens and culinary use.
A Note on Variegated Varieties
Some popular ornamental varieties of Portulacaria afra include variegated types like 'Foliis variegatis' and 'Variegata'. While these are beautiful, it's widely noted that their leaves can be bitter and are generally not recommended for culinary use. Stick to the plain green varieties for the best taste and experience. When purchasing, always check the plant tag to confirm the exact cultivar. If no tag is present, it's safer to use leaves from a plant you are certain is a standard, green Portulacaria afra.
