From Garden to Glass: How a Lobelia Found New Life in Water

The Unexpected Delight: Thriving Lobelia in Water

November’s embrace in Pittsburgh often signals the end for many garden beauties. Yet, this year, a gardener discovered a secret: the vibrant LAGUNA® Dark Blue Lobelia, stubbornly clinging to its glory, had a trick up its sleeve. Instead of succumbing to the impending winter, this resilient plant underwent an extraordinary transformation, one that’s been bringing joy ever since.

A Late Season Surprise

As the days grew shorter and the air turned crisp, the gardener noticed the lobelia’s persistent beauty. A decision was made, a gamble perhaps, to bring the outdoor plant inside. The process was simple, yet the results have been anything but. After gently rinsing the soil from the roots, the plant was placed in water. The lobelia didn’t just survive; it thrived, embarking on a continuous blooming cycle.

The Allure of Lobelia

Lobelia, with its delicate, jewel-toned flowers, is a favorite among gardeners. The LAGUNA® Dark Blue variety, in particular, offers a stunning display, its deep blue petals creating a striking contrast against lush green foliage. Traditionally, lobelia is an annual, often gracing hanging baskets and borders throughout the warmer months. But this instance demonstrated that with a little innovation, the beauty of lobelia can extend far beyond its typical season.

The Science Behind the Success

While the exact mechanisms of this aquatic adaptation may vary, some principles are generally applicable for this kind of growing method, known as hydroponics. The key is understanding the plant’s basic needs and ensuring they are met in a water-based environment.

• Water Quality: Clean, fresh water is crucial. Regular changes are recommended to prevent the buildup of harmful substances and to provide adequate oxygen to the roots. Some gardeners may opt to use filtered water to avoid any potential issues with tap water impurities.
• Nutrients: Plants need nutrients to grow. While the initial transition to water may allow a plant to use reserves stored in its tissues, it won’t last forever. It is likely that the gardener is providing nutrients to the plant, as continuous blooming suggests. Water-soluble fertilizers, specifically designed for hydroponic systems, are ideal. These fertilizers contain a balanced mix of essential macro- and micronutrients that the plant can readily absorb through its roots.
• Light: Lobelia thrives in bright, indirect light. When grown indoors, a location near a window that receives ample sunlight is often best. Avoid direct sunlight, which can scorch the delicate leaves. Supplemental lighting, such as a grow light, can also be beneficial, especially during the shorter days of winter.
• Aeration: Oxygen is essential for root health. In a water-based system, the roots can suffocate if deprived of oxygen. Some gardeners use an air pump and an air stone to oxygenate the water. Regular water changes also help to maintain oxygen levels.

Replicating the Magic: Tips for Success

Inspired by this success story, you might be tempted to try your own hand at growing lobelia in water. Here are some tips to increase your odds of success:

1. Choose the Right Plant: While the LAGUNA® Dark Blue variety has proven its adaptability, it’s worth noting that not all lobelia varieties might respond equally well to this method. Consider starting with a healthy, well-established plant.
2. Cleanliness is Key: Thoroughly rinse all soil from the roots. Any remaining soil can contaminate the water and lead to problems.
3. Provide Adequate Support: Depending on the plant’s size and growth habit, you may need to provide some form of support. This could be as simple as a decorative vase with a narrow neck or a more elaborate hydroponic setup.
4. Monitor and Adjust: Keep a close eye on your lobelia. Watch for any signs of stress, such as yellowing leaves or stunted growth. Adjust your care routine as needed, experimenting with different light conditions or nutrient solutions.
5. Embrace the Experiment: Gardening is, at its heart, an experiment. Don’t be afraid to try new things and learn from your experiences. Each plant, each environment, and each gardener is unique.

Beyond Lobelia: Exploring Hydroponics

The success with lobelia opens the door to explore the world of hydroponics, a method of growing plants without soil. Instead, plants are cultivated in water, with or without the use of an inert medium like perlite or vermiculite to provide support. Hydroponics offers several advantages:

• Water Conservation: Hydroponic systems can be very water-efficient, as the water is often recirculated and reused.
• Controlled Environment: Indoor hydroponic setups allow for precise control over environmental factors such as light, temperature, and humidity.
• Faster Growth: Plants often grow faster in hydroponic systems due to readily available nutrients and optimal growing conditions.
• Space Efficiency: Hydroponics can be ideal for small spaces, such as apartments or urban gardens.

Conclusion

The story of the thriving LAGUNA® Dark Blue Lobelia in water is a testament to the adaptability of nature and the power of observation. It’s a reminder that sometimes, the most rewarding discoveries come from the simplest experiments. With a little patience and a willingness to try new things, you too can extend the beauty of your garden indoors, and enjoy the vibrant blooms of lobelia throughout the year.
