What is Philodendron Gigas

Philodendron Gigas is a plant native to Panama. In its natural environment, it can grow up to 65 feet tall, with leaves reaching lengths of 3-4 feet. Indoors, it grows to about 8-10 feet tall, with leaves around a foot long. The plant’s velvety leaves have a mix of green and copper colors that change as they mature.

This plant grows quickly and can increase in size over the course of a year. It likes to climb, so a moss pole or trellis is useful for indoor growth. It can also be grown in a hanging basket, where the vines may extend over time.

Philodendron Gigas does best in rich, fast-draining soil that holds some moisture without becoming waterlogged. It prefers a slightly acidic to neutral pH between 5.6 and 7.5. While it grows best in indirect sunlight, it can tolerate low light, though the leaves may become smaller. It’s important to avoid direct sunlight to prevent leaf damage.

As a tropical plant, Philodendron Gigas prefers warm, humid conditions. It thrives in temperatures between 60 and 85°F, with a humidity level of around 60%.

What is Philodendron Melanochrysum

Philodendron Melanochrysum, also called the black-gold philodendron, is a houseplant known for its attractive leaves. The plant has dark green, velvety leaves with yellow veins.

This plant grows in shaded forest areas, where it gets indirect light. When grown indoors, it does best with bright, indirect light. It usually doesn’t need much pruning, but you can trim it if it gets too big for your space. In its natural environment, it climbs trees. Indoors, using a moss pole can help the plant grow larger leaves, sometimes reaching up to 24 inches.

For potting, choose a well-draining soil mix that stays slightly moist but not too wet to avoid root rot. The plant prefers regular watering to keep the soil moist. It grows best in temperatures between 65 and 80°F and needs humidity levels of 50% or more. Using a humidifier or placing it in a humid spot can help it stay healthy.
