Dutchman's Gold is a delightful hybrid between Cym Golden Elf and Cym madidum. The bright butter yellow bloom has a natural spread of 4.5-5.5 cm. The bright colour is normally brought up when combine the ensifolium line with madidum.
It is a robust heat tolerant cymbidium with sweet fragrance that inherited from both Golden Elf and madidum. In Bangkok, Dutchman's Gold starts blooming in August and end in April. With its high heat tolerance, it can bloom in all equatorial areas.
3 Stages for Successful Blooming of Cymbidiums vs. The Use of HTC & WTC

The process from flower bud induction in the new growth to blooming can be divided into three stages.
Stage I : Flower Bud Initiation in the New Growth
Stage II : Flower Spike Initiation
Stage III : Spike Elongation and Blooming
Stage I : Flower bud initiation in the new growth(This stage does not require the temperature as low as Stage II and III)
Normally, flowers of a cymbidium are initiated within the new growing pseudobulb. If the plant grows in suitable conditions, where night temperatures are below the plant’s required maximum night temperature, their pseudobulbs will be bigger and healthier with larger and thicker leaves. Commonly, lower temperature at night reduces plant respiration; therefore plants expend less stored energy. As a result, more energy is accumulated in their storage organs. Eventually, those pseudobulbs have a higher potential to produce better quality flowers with a higher flower count.
If the required night temperatures are not met, pseudobulbs will tend to produce poorer quality flowers and a lower flower count per stem. In the worst scenario, they may not produce any blooms at all. This means that no matter how you treat those pseudobulbs, they will not produce any flowers, even though they may later experience a cooler growing environment. Literally, those pseudobulbs are wasted.
It is a general rule that the large-flowered types need greater energy storage in their pseudobulbs than the smaller-flowered types do. In other words, the large-flowered types require lower night temperatures than the smaller-flowered types do.
Traditionally, all the commercial large-flowered cymbidiums have been developed from large-flowered species that originally came from the foothills of Himalayan Mountains, starting from northern India, Nepal, Bhutan, northern Burma, and southwestern China and throughout many smaller ranges in Vietnam, Laos and northern Thailand. In these original habitats, their climate is divided into wet and dry cycles.
Cymbidium Lilliput is a great heat tolerant cymbidium. This primary cross is a remake of the long lost hybrid. In this cross, we use Cym ensifolium subsp. haematodes from Thailand incorporated with the large flowered species, Cym lowianum, from Shan, Myanmar.
Spike characteristics are different in each seedlings; some are upright, some are suberect/arching and some are pendulous. Plus, the flowers are slightly fragrant. Lilliput can bloom very well even in the equatorial zones.
