Watercress is a Common Green in the US Market
Despite its historic European origins, watercress is a common and accessible leafy green in the American market. You can typically find it in the produce section of well-stocked supermarkets, health food stores, and specialty grocery retailers. Its spicy, peppery flavor and tender leaves make it a popular addition to salads, soups, and sandwiches. The ability to find it fresh depends on the retail location, but national suppliers and local growers ensure a consistent supply.
Where to Purchase Watercress
Whether you live in a bustling city or a more rural area, there are several reliable options for sourcing watercress in the USA.
- Major Supermarkets: Chains like Whole Foods, Central Market, and many large national and regional grocery stores often carry watercress year-round. It is usually packaged in small bunches and located with other leafy salad greens.
- Farmers' Markets: As a cool-weather crop, watercress frequently appears at farmers' markets, especially during the spring and fall. Buying from a local farmer can ensure peak freshness and support local agriculture.
- Online Grocers and Specialty Retailers: For those in more remote locations or seeking organic options, numerous online food delivery services and specialty sites offer fresh watercress delivered to your door. These services often provide high-quality, sustainably grown produce.
Wild Foraging in the USA
Watercress is also known to grow wild in the USA, particularly in areas with running spring water, creeks, and moist ground. It is important to note that while foraging can be a rewarding activity, you should only do so if you can positively identify the plant and are certain the water source is free from pollutants and contaminants. The US Forest Service considers it invasive in many states, so it's a good idea to check local regulations before foraging. Wild watercress often has a more intense flavor than its cultivated counterpart.
Can You Grow Your Own Watercress in the USA?
For the freshest possible supply, many Americans opt to grow their own watercress at home. This can be done successfully even without a flowing stream, using simple hydroponic setups or containers. This is an excellent option for year-round availability, especially if you have a controlled indoor environment.
Growing Watercress at Home: Key Considerations
- Moisture: The most critical factor is providing consistent moisture. A simple method is using a two-pot system where one pot with drainage holes sits inside a larger one without drainage to collect water. Alternatively, you can use a water feature or pond edge if available.
- Sunlight: Watercress prefers cooler temperatures and thrives in full sun but can tolerate partial shade, which is beneficial during the heat of summer.
- Cool Temperatures: As a cool-weather plant, watercress grows best in temperatures between 50 and 60 degrees F. It may require afternoon shade or indoor growing during intense summer heat.
- Harvesting: You can harvest watercress microgreens in as little as 10-15 days or wait three weeks for more mature leaves and stems. It's best to harvest before the plant flowers, as this can cause the leaves to become more bitter.
