1. Introduction
【Child】
Why, hello Professor! I was just reading Ophelia’s soliloquy from Shakespeare’s Hamlet where she talks about flowers, and it got me all curious about plants submerged in water. Can they be as delightful to look at as those that grow on land?
【Professor】
Ah, a wonderful question, my inquisitive little friend! Indeed, the world of aquatic plants is as enchanting as the terrestrial ones. Today, let’s dive deeper into a captivating aquatic plant known as Lobelia cardinalis. Through our conversation, I hope you’ll see the beauty and allure of this underwater flora just as much as those on land.
2. Characteristics
【Child】
Professor, if Lobelia cardinalis were a character from a great novel or a work of art, who or what would it be?
【Professor】
An intriguing comparison, dear child! I would say Lobelia cardinalis resembles the persona of Elizabeth Bennet from Jane Austen’s “Pride and Prejudice.” Much like Elizabeth, this plant is quite versatile, adapting well to various situations. Its leaves have an elongated lanceolate shape and are of a rich green hue. When it blooms, it produces striking red-violet flowers, just like Elizabeth’s colorful personality.
In terms of aquarium layouts, Lobelia cardinalis can be used as a bold focal point in small aquariums or a charming, verdant backdrop in larger aquariums. Positioned in either the foreground or background, this plant can achieve its maximum figure, providing an enthralling scenery.
3. Cultivation
【Child】
Like a master chef trying to perfect a dish, what would be the difficulty level for cultivating Lobelia cardinalis? Are there any tricks to making it thrive in an underwater environment?
【Professor】
I love your metaphor, young gastronome! Cultivating Lobelia cardinalis can be considered moderately difficult. This mainly requires attention to a few crucial factors. One must ensure adequate lighting, as the plant needs a fair amount of luminance to thrive. In terms of water parameters, the optimum conditions are a pH of 6.0-7.5, GH of 3-10, and kH of 3-8.
Additionally, the water temperature should be maintained between 20-28°C (68-82°F). Proper substrate, such as nutrient-rich bottom sand, is essential for rooting and growth. Lastly, don’t forget to provide sufficient CO2 and fertilizers to enrich the plant and promote vibrant coloration.
As an aquatic plant connoisseur, I must also mention that Lobelia cardinalis can be propagated not only underwater but also above water. It forms side shoots and quickly multiplies when provided with the right conditions, like a talented writer producing multiple volumes of enthralling novels.
4. Precautions
【Child】
In the spirit of Aesop’s fables, are there any lessons or precautions one should heed while caring for Lobelia cardinalis, particularly when other underwater creatures share its space?
【Professor】
Your curiosity is simply insatiable, and I admire that! Indeed, there are precautions to take when it comes to cultivating Lobelia cardinalis alongside other aquatic inhabitants. First and foremost, ensure that the fish or invertebrates you introduce to the aquarium are compatible with aquatic plants in general. Avoid species known to nibble on or uproot plants, as it may hinder the growth and beauty of your Lobelia cardinalis.
Secondly, remember that different plants and aquatic inhabitants may require differing water parameter ranges, so make sure that their needs overlap and are met for a peaceful, thriving underwater environment.
5. Summary
【Child】
As we reach the final chapter of our conversation, may you kindly summarize the captivating charm and secrets of Lobelia cardinalis in the enchanting world of underwater botany?
【Professor】
Of course, dear child! Lobelia cardinalis is a delightful and versatile aquatic plant, akin to a heroine from a classic novel. Bearing elongated lanceolate leaves along with captivating red-violet flowers, it can serve as a focal point or background in various aquarium layouts.
Cultivating this plant requires moderate care, paying attention to factors such as light, water parameters, temperature, substrate, and nutrients. Take precautions when pairing it with other inhabitants to ensure a harmonious underwater environment.
I hope our conversation has illuminated the beauty and allure of Lobelia cardinalis, an aquatic gem that is truly as delightful and full of character as the terrestrial plants that inspired your curiosity. Until our next deep dive into the marvelous world of aquatic plants!
