A common search for many plant enthusiasts involves the “blue spider plant,” often sparking curiosity about its existence and appearance. Understanding whether such a plant truly exists, or if it’s a misinterpretation, can guide individuals toward finding the ideal blue-hued additions for their collections.
Decoding the Blue Spider Plant Name
The common spider plant, scientifically known as Chlorophytum comosum, does not naturally produce blue foliage. Instead, these popular houseplants are recognized for their arching, ribbon-like leaves, which typically display shades of green, white, or yellow, often with variegation. The notion of a “blue spider plant” likely stems from confusion or a desire for a unique color not found in the natural forms of Chlorophytum comosum. While some plants are artificially dyed, a true, botanically recognized blue spider plant variety does not exist.
Popular Houseplants with Blue or Blue-Green Foliage
For those seeking the striking aesthetic of blue or blue-green foliage, several houseplants offer this captivating coloration. One such option is Senecio serpens, commonly known as Blue Chalk Sticks. This succulent features short, cylindrical, finger-like leaves with a distinctive powdery blue-gray or blue-green hue. It grows in dense clusters, forming a low-spreading mat.
Another group of plants that often display blue tones are Echeveria species. Many Echeverias, such as ‘Powder Blue’ or ‘Blue Prince’, have thick, fleshy leaves arranged in tight rosettes, often appearing in shades of blue-gray or blue-green. The blue coloration in Echeveria is often due to a powdery coating called farina, which gives the leaves a soft, pastel look and can intensify with bright light.
Tradescantia pallida ‘Purpurea’, known as Purple Heart Plant, also offers a deep, rich color that can be perceived as blue-ish purple depending on lighting and individual perception. This plant has slender, pointed leaves that are a vibrant violet-purple, with new leaves emerging in deeper shades. Its stems trail elegantly, making it a dramatic addition to a collection.
Essential Care for Blue-Hued Houseplants
Maintaining the vibrant blue or blue-green coloration of these plants often depends on specific care conditions, particularly light exposure. Most blue-hued succulents, like Senecio serpens and Echeveria varieties, require ample bright, indirect light to maintain their color intensity. Insufficient light can cause these plants to become leggy and their colors to fade. Some Echeverias even develop pink or red tips in bright sun.
Watering practices are also critical, especially for succulents. It is recommended to use a “soak and dry” method, allowing the soil to dry out completely between waterings. Overwatering is a common issue that can lead to root rot, so ensuring good drainage is paramount. For Tradescantia pallida ‘Purpurea’, the soil should be allowed to dry out slightly before rewatering, avoiding waterlogging.
Well-draining soil is crucial for the health of these blue-foliaged plants, especially succulents. A cactus or succulent potting mix, often containing perlite, pumice, or coarse sand, promotes good aeration and prevents water retention around the roots. While many blue-hued plants prefer warmer temperatures, protection from freezing conditions is important for tender varieties, with typical indoor temperatures between 65°F to 75°F being suitable.
