About Cast Iron Plant
The ultimate low-maintenance houseplant — tolerates neglect, deep shade, temperature extremes, and poor soil. Its dark green, lance-shaped leaves grow directly from the soil on long stems, forming an elegant clump that thrives where other plants fail. Cast Iron Plant belongs to the Asparagaceae family and originates from Japan and Taiwan; cultivated worldwide as a houseplant..
Cast iron plant is underrated in Philippine gardening — perfect for the shaded ground-floor areas of townhouses, under stairs, or north-facing condo balconies where nothing else survives. It handles the occasional typhoon flooding and AC-dried air equally well. Available at Ace Hardware garden sections, plant shops in Commonwealth and Marikina, and online sellers.
Also known as: Bar Room Plant, Aspidistra elatior.
