Growing a mature Philodendron lupinum transforms a charming juvenile plant into a striking specimen. This aroid distinguishes itself through a remarkable change in its foliage as it ages, evolving significantly from its initial smaller form. Understanding its journey to maturity allows enthusiasts to cultivate its full potential, revealing impressive characteristics.
Understanding Philodendron Lupinum
Philodendron lupinum originates from the tropical rainforests, primarily found in the state of Acre in Brazil, and also extending into parts of Colombia and Peru. This vining plant naturally thrives in warm, humid environments, often beginning its life in the tree canopy before sending roots down to the forest floor. Its growth habit is hemiepiphytic, meaning it can grow on other plants but also roots in the soil, and it shows a strong inclination to climb.
In its juvenile stage, Philodendron lupinum presents small, heart-shaped leaves that typically measure between 1 to 2 inches (2.5 to 5 cm) long. These young leaves are notable for their velvety texture on the upper surface and a distinct dark maroon or reddish underside.
The Maturation Journey
Plant maturity for vining philodendrons involves a transition from juvenile to adult form, often marked by significant changes in leaf morphology. For Philodendron lupinum, this maturation is largely triggered by environmental cues and the provision of appropriate vertical support. The plant needs something to climb, such as a moss pole or totem, to initiate this change.
Adequate light, consistent humidity, and stable temperatures also play a part in encouraging this transformation. As the plant climbs, its stem thickens and the internodes shorten, signaling to the plant that it is ready to produce larger, more developed leaves. The timeline for Philodendron lupinum to reach maturity can vary, but it often takes several years, with some growers noting it can take three to four years to see substantial changes.
Distinctive Features of Mature Philodendron Lupinum
A mature Philodendron lupinum undergoes a profound transformation, resulting in leaves that look remarkably different from their juvenile counterparts. The most striking change is a significant increase in leaf size, with mature leaves potentially reaching up to 20 inches (50 cm) in length. These larger leaves lose their initial heart shape and velvety texture, becoming elongated, often lance-shaped, and developing a glossy, corrugated surface.
The deep maroon undersides present in juvenile leaves may fade or become less pronounced as the plant matures. Mature leaves showcase a more robust and textural appearance with visible venation. This dramatic shift makes a mature Philodendron lupinum a highly sought-after specimen.
Caring for a Mature Philodendron Lupinum
Caring for a mature Philodendron lupinum requires adjusting care practices to accommodate its larger size and established growth. Providing sturdy and tall support structures, such as a substantial moss pole or trellis, becomes increasingly important as the plant continues to climb and produce larger leaves.
Mature plants generally require increased watering and fertilization compared to their juvenile forms due to their larger leaf surface area and more extensive root systems. It is advisable to allow the top inch or two of soil to dry out between waterings, ensuring thorough saturation when watering to prevent root rot. A balanced liquid fertilizer applied monthly during the growing season can support vigorous growth. Repotting may be necessary every few years to provide adequate space for root expansion and replenish soil nutrients.
