Cebu Blue (Epipremnum pinnatum 'Cebu Blue'): A Shimmering Beauty

Introduction:

The Cebu Blue is a unique cultivar of the Epipremnum pinnatum species, featuring delicate, silvery-blue leaves that shimmer in the light. The plant’s leaves are long, narrow, and lance-shaped when young, and they can develop fenestrations (splits) as the plant matures and climbs. Its trailing or climbing growth makes it an excellent choice for hanging baskets, trellises, or trained up a moss pole.

History:

Native to the tropical island of Cebu in the Philippines, the Cebu Blue is a naturally vining plant that climbs trees in the wild, using aerial roots to cling to bark. As part of the Araceae family, which includes popular houseplants like pothos and philodendrons, the Cebu Blue is known for its hardiness and ability to adapt to a variety of indoor environments. Its subtle, blue-green coloration gives it a distinct look compared to other Epipremnum species.

Care Outline:

• Light: The Cebu Blue prefers bright, indirect light, which will help it maintain its vibrant blue-green coloring. While it can tolerate lower light conditions, it may lose some of its characteristic color and grow more slowly. Aim for 10,000 to 20,000 lux.
• Water: Water the plant when the top inch of soil is dry. It’s important not to overwater, as the Cebu Blue is susceptible to root rot if left in soggy soil. Water thoroughly, but make sure the pot has good drainage.
• Humidity: While the Cebu Blue can tolerate average household humidity, it will thrive in higher humidity environments (60%-80%). Increased humidity encourages faster growth and healthier foliage.
• Temperature: The plant prefers temperatures between 65°F to 85°F (18°C to 29°C). Avoid exposing it to temperatures below 55°F (13°C) or cold drafts, which can stunt growth or damage the plant.
• Soil: Use a well-draining potting mix. A mix of peat moss, perlite, and orchid bark works well to retain moisture while allowing good airflow around the roots.
• Fertilizer: Fertilize monthly during the growing season (spring and summer) with a balanced, water-soluble fertilizer (e.g., 10-10-10 or 20-20-20) at half strength. Reduce feeding in the fall and winter when growth slows.
• Propagation: The Cebu Blue is easy to propagate through stem cuttings. Root cuttings in water or soil, and new growth will emerge in a few weeks.

Light and Lux Rating:

The Cebu Blue thrives in bright, indirect light with a lux rating of 10,000 to 20,000 lux. It can tolerate lower light conditions, but its blue-green hues will be more vibrant in brighter, indirect light.

• Natural Light: Place the plant near an east or north-facing window for bright, indirect light. If using a west or south-facing window, be sure to filter the light to prevent the leaves from scorching.
• Artificial Light: If growing under artificial light, make sure the Cebu Blue gets enough intensity. Grow lights providing 10,000 to 20,000 lux will help keep the plant healthy and colorful.

Propagation:

1. Stem Cuttings:

• Best Time: Spring or early summer during the plant’s active growing season.
• Steps:
  1. Cut a healthy vine just below a node (the place where a leaf meets the stem).
  2. Place the cutting in water or a moist, well-draining soil mix.
  3. In water, roots should appear within a few weeks. Once the roots are about 2–3 inches long, transplant the cutting into soil.
  4. In soil, keep the cutting in a warm, humid environment until new growth begins.

2. Air Layering:

• You can also propagate by air layering, wrapping moist sphagnum moss around a node and securing it with plastic wrap until roots develop.

Soil for Cebu Blue:

A well-draining, airy mix is essential for the Cebu Blue to thrive. A good mix includes:

• Peat moss for moisture retention.
• Perlite or pumice for drainage and aeration.
• Orchid bark to encourage airflow around the roots.

This mix allows water to flow through easily, preventing the plant from sitting in waterlogged soil.

Fertilizing:

• During the growing season (spring and summer), feed the plant with a balanced, water-soluble fertilizer diluted to half strength once a month.
• Avoid over-fertilizing, as it can lead to a buildup of salts in the soil, which may harm the plant’s roots.
• In fall and winter, reduce fertilization as the plant’s growth naturally slows down.

Repotting:

• When to Repot: Repot your Cebu Blue every 1–2 years or when it becomes root-bound.
• Best Time: Repotting is best done in early spring, just before the growing season begins.
• Steps:
  1. Gently remove the plant from its pot and inspect the roots for any signs of damage or rot.
  2. Repot in a slightly larger container with fresh, well-draining soil.
  3. Water thoroughly after repotting and place the plant in bright, indirect light.
