FAQs: Frequently Asked Questions

Can Nasturtiums grow indoors?

Yes, Nasturtiums can be successfully grown indoors. To do so, choose a pot with good drainage and fill it with well-draining potting mix. Place the pot in a location that receives plenty of sunlight, ideally a south-facing window that gets at least 6 hours of direct sunlight daily. Indoor Nasturtiums can add a splash of color to your home and also serve as an edible addition to your kitchen garden. Ensure to water them regularly, keeping the soil moist but not waterlogged, and watch out for common indoor pests like aphids.

Are Nasturtiums perennials or annuals?

Nasturtiums are typically grown as annuals, meaning they complete their life cycle in one growing season. However, in frost-free, warmer climates, they can behave like perennials, surviving and blooming year after year. In colder regions, they will die off after the first frost, but they are known for self-seeding, often reappearing the following spring without the need for replanting. This makes them a versatile and resilient choice for a wide range of garden environments, offering prolonged beauty with minimal effort.

How do I harvest Nasturtium seeds?

Harvesting Nasturtium seeds is straightforward and can be a rewarding way to propagate your plants for the next season. Allow the flowers to fade and the seeds to mature on the plant. The seeds will swell and turn from green to brownish as they ripen. Once they start to dry and detach easily from the plant, collect them. Spread the seeds out on a paper towel or tray to dry thoroughly for a week or two, then store them in a cool, dry place. Properly dried and stored seeds can remain viable for several years.

Do Nasturtiums attract bees?

Yes, Nasturtiums are excellent for attracting bees and other beneficial pollinators to your garden. Their bright, vibrant flowers are rich in nectar, making them an attractive food source for bees, butterflies, and hummingbirds. This not only helps with the pollination of your Nasturtiums but also benefits other plants in your garden by increasing overall pollination activity. By planting Nasturtiums, you can create a more biodiverse and healthy garden ecosystem, promoting the presence of beneficial insects and improving the yield of other flowering plants and vegetables.

Can I eat Nasturtium leaves?

Absolutely! Nasturtium leaves are not only edible but also delicious. They have a peppery, slightly spicy flavor that adds a unique kick to salads, sandwiches, and garnishes. The leaves are packed with vitamin C and other nutrients, making them a healthy addition to your diet. You can use them fresh in salads, blend them into pestos, or use them as a flavorful wrap for various fillings. Their distinct taste and nutritional benefits make them a popular choice among edible flowers and garden greens.
