Cattleya Percivaliana

If you’re looking for a stunning orchid that also brings a beautiful scent to your room, look no further. The Cattleya percivaliana is an exquisite orchid with fragrance that truly stands out. It’s often called the “Christmas Orchid” because it tends to bloom around the holiday season, offering a spectacular show of color and smell. This guide will help you understand everything you need to grow one successfully.

Native to Venezuela, this orchid grows on rocks and trees in cool, mountainous forests. It’s known for its resilience and its stunning lavender to rose-colored flowers. Each bloom has a lovely, spicy-sweet perfume that is strongest in the afternoon. It’s a rewarding plant for both new and experienced growers who follow a few key steps.

This specific Cattleya is a classic among collectors. It produces relatively short pseudobulbs and one or two leathery leaves. The flower spike appears from a sheath at the top of the newest, mature pseudobulb. Typically, it will produce between two to five flowers per spike, and each flower can be up to 4 inches across. The lip is a deep, rich purple, which creates a gorgeous contrast with the lighter petals.

Ideal Growing Conditions for Success

Getting the environment right is the most important part of orchid care. This plant has specific needs, but they are easy to meet once you know them.

Light: Cattleya percivaliana needs bright, indirect light. An east or west-facing window is perfect. The leaves should be a light grassy green color. If they turn dark green, it needs more light; if they become yellowish, it’s getting to much sun.
Temperature: This is a cool to intermediate grower. It prefers daytime temperatures between 70-80°F (21-27°C) and a noticeable drop at night to 55-60°F (13-16°C). This temperature difference is crucial for triggering blooms.
Humidity: Aim for 50-70% humidity. You can use a humidity tray filled with pebbles and water or a small room humidifier placed nearby. Good air movement is essential to prevent fungal issues in humid conditions.

Step-by-Step Planting and Potting Guide

Repotting is needed every 2-3 years or when the potting mix breaks down. The best time to repot is right after flowering, just as you see new roots starting to grow from the base of the new lead.

Choose the Right Pot: Use a specialized orchid pot with plenty of drainage holes. A clay pot is excellent because it breathes and helps prevent overwatering.
Select a Proper Mix: Use a coarse, fast-draining medium. A mix of medium-grade fir bark, perlite, and charcoal works very well. Don’t use regular potting soil.
Remove the Old Medium: Gently take the orchid out of its old pot. Carefully remove all the old bark from around the roots, being cautious not to break healthy roots.
Trim if Necessary: Use sterilized scissors to cut away any dead, mushy, or papery roots. Healthy roots are firm and white or greenish.
Position in the Pot: Place the plant in the new pot so the oldest pseudobulbs are against the edge and the new growth points toward the center. This gives the plant room to grow across the pot.
Add New Mix: Hold the plant in place and fill in around the roots with your new mix. Gently tap the pot to settle the medium. You can use a stake to support the plant until its roots take hold.

Watering and Feeding Your Orchid

Overwatering is the fastest way to harm an orchid. These plants are epiphytes, meaning they’re used to having their roots dry out quickly.

Watering Frequency: Water thoroughly when the potting medium is nearly dry. In warmer months, this might be once a week. In cooler, darker months, it could be every 10-14 days. Always check the moisture level with your finger first.
How to Water: Take the plant to a sink and run lukewarm water through the pot for about 15-20 seconds. Let it drain completely before putting it back in its decorative container. Never let it sit in standing water.
Fertilizing: Feed with a balanced orchid fertilizer (like 20-20-20) at half-strength. A good rule is to “feed weekly, weakly.” Fertilize every other week during the active growth period (spring and summer). Flush the pot with plain water once a month to prevent salt buildup from the fertilizer.

Encouraging Those Beautiful Blooms

The main goal is to see and smell those gorgeous flowers. If your plant is healthy but not blooming, check these two factors.

First, ensure it’s getting enough light. Inadequate light is the number one reason orchids fail to flower. Second, make sure it’s experiencing that cooler nighttime temperature drop of at least 10-15 degrees. This is the natural signal for the plant that it’s time to initiate flower spikes.

Common Problems and Simple Solutions

Even with great care, you might encounter an issue. Here’s how to handle common ones.

No Flowers: Not enough light or insufficient temperature drop at night. Move it to a brighter location and ensure it gets cooler evenings.
Yellowing Leaves: Could be too much direct sun, overwatering, or a natural process. Older leaves at the base of the pseudobulb will yellow and fall off eventually—this is normal. New leaves yellowing is a problem.
Wrinkled Pseudobulbs: This usually indicates underwatering or that the roots have rotted from overwatering and can’t take up moisture. Check your roots and adjust your watering schedule accordingly.
Pests: Watch for scale, mealybugs, or spider mites. Wipe leaves with a soft cloth and use an insecticidal soap or horticultural oil as directed if you see pests.
