Growing and Utilizing Capers: A Guide
Are you looking to add a unique plant to your garden that not only offers beautiful blooms but also tasty treats for your dinner table? If so, the caper bush might be just the plant you’re seeking. This article will provide you with all the information you need to successfully grow and utilize capers in your own garden.
Exploring the World of Capers
Have you ever wondered what capers actually are? Capers are the edible flower buds of the caper bush, known scientifically as Capparis spinosa. These flower buds, as well as the edible berries produced by the plant, are pickled before being consumed due to their bitter taste when raw. The pickled capers have a piquant, tangy flavor, making them a delightful seasoning or condiment, especially when paired with fish or other rich foods.
In addition to the flower buds and berries, other parts of the C. spinosa plant, such as the leaves, are also utilized in traditional medicines and cosmetics.
Cultivating Capers: The Basics
Native to the Mediterranean region, caper bushes thrive in dry, sunny conditions and require well-drained, rocky soil to grow successfully. These evergreen plants do not tolerate temperatures below 18°F, so in colder climates, it’s best to grow them in containers and overwinter indoors. Capers bushes typically grow three to five feet in height and can spread four to five feet wide. They are also known to thrive when planted on masonry walls, making them a unique and visually appealing addition to your garden.
While caper cultivation isn’t as widespread in the US compared to the Mediterranean region, gardeners in the southwest and parts of California have reported success growing these plants. If you’re in a climate similar to the Mediterranean, like Central Texas, it might be worth considering adding capers to your garden.
Propagation: From Seeds to Cuttings
Propagating capers can be a bit challenging, but here’s an overview of the two main methods commonly used:
From Seed:
– Fresh seeds are best for germination. If you don’t have fresh seeds, cold stratification is needed, and germination can be sporadic and lengthy.
– Soak seeds in warm water for 12 hours, refrigerate, then plant in a mix of planting mix, perlite, and sand.
– Seedlings should emerge within 3-4 weeks and can then be transplanted to larger containers or the ground.
From Cuttings:
– Take 3-4 inch cuttings from mature plant stems and root them in a potting mix.
– Flowering may take two to three years from cuttings.
Growing Healthy Caper Plants
Once you’ve successfully propagated your capers, it’s essential to provide them with the right growing conditions for optimal development. Here are some tips for growing healthy caper plants:
- Choose a site with excellent drainage and plenty of sunlight.
- Water young plants frequently for the first two years, then reduce watering as they mature.
- Fertilize with a balanced fertilizer during the spring and summer months.
- Prune mature plants to the ground in late fall or early winter.
Selecting the Right Cultivars
In the US, a variety of caper bush cultivars may not be readily available. Look for spineless varieties if thorns are a concern, and consider ‘Senza spina’ and ‘spinosa comune’ as potential options. If you’re feeling adventurous, you can also try growing capers from seeds, which may be available online.
Dealing with Pests and Diseases
Keeping your caper plants healthy involves managing pests and diseases that may impact their growth. While weevils can be a common issue in the US, other insect pests like shield bugs and flies are more prevalent in Mediterranean regions. Treat pests with diatomaceous earth or insecticidal soap to protect your caper plants. Additionally, be on the lookout for fungal infections and cucumber mosaic virus, as they can affect the health of your caper bushes.
Harvesting and Preserving Capers
Knowing when and how to harvest capers is crucial to enjoying their delightful flavor. Harvest the immature flower buds when they reach the desired size, typically 6-14 millimeters in diameter. Preserving capers can be done by pickling in either salt or vinegar solutions. Remember to rinse and clean the capers thoroughly before preserving them.
Recipes and Culinary Ideas
Once you’ve grown and preserved your capers, it’s time to get creative in the kitchen. Try adding capers to classic dishes like Greek salad, Homemade Einkorn Ravioli, or Chicken Piccata for a burst of tangy flavor. Experiment with incorporating capers into your favorite recipes to discover new and exciting culinary creations.
Considering Nasturtiums as an Alternative
If you’re looking for a caper substitute or a unique addition to your garden, consider growing nasturtiums. These vibrant flowers are easy to care for, drought-tolerant, and their seeds are said to have a taste similar to capers. Nasturtiums can be a versatile and visually appealing plant for your landscape, offering both aesthetic beauty and potential culinary uses.
