Details |
| 🔧 Skill Level |
Intermediate – The main challenges are providing very bright light to encourage blooming and respecting its winter rest period. Once you understand these needs, it is very rewarding. |
| 🌍 Native Region |
Costa Rica, Panama, and Colombia |
| ⛰️ Elevation Range |
From sea level to mountain forests (250 - 2,500 metres) |
| 🪴 Plant Size |
Medium-sized, with club-shaped pseudobulbs 8-20cm tall, each topped with a single, thick, oblong leaf up to 22cm long. |
| 🎍 Terrarium Suitable? |
No – It requires more space and excellent air movement than a terrarium can usually provide. |
| ☀️ Flowering Season |
Late summer through to autumn. |
| 🌸 Bloom Traits |
Large, showy flowers, typically 3-6 per spike. The petals are a vibrant golden-yellow, while the trumpet-shaped lip is a rich crimson-purple with intricate gold veining. |
| 👃 Fragrance |
Strong, sweet, and complex, often described as a delightful mix of vanilla, lemon, and spice. |
| 🌡️ Temperature |
Summer (Growth): 24-30°C days / 16-20°C nights
Winter (Rest): Keep drier and slightly cooler, with nights no lower than 15°C. |
| 💧 Watering |
Water thoroughly when the potting mix is nearly dry. During active growth (spring/summer), this may be every 5-7 days. Reduce watering significantly in winter after growths have matured, keeping the mix just barely moist to prevent shrivelling. |
| ☁️ Humidity |
High (60-80%). Good air circulation is essential to prevent spotting and rot. |
| 💡 Light |
Very bright, filtered light. This is a crucial factor for blooming. Leaves should be a light, apple-green colour. If they are dark green, increase light. A south or west-facing window is ideal. It can tolerate some morning or late afternoon sun. |
| 🌰 Growing Medium |
Open, fast-draining mix, e.g., medium-large fir bark chips, perlite, and charcoal. Repot every 2-3 years in spring when new roots appear. |
| 🧪 Fertilisation |
March - October: Apply a balanced orchid fertiliser (e.g., 20-20-20) at half strength every two weeks.
November - February: Do not fertilise during the winter rest. |
