  • Orchid named ‘HONEY MICHELL’
    Patent number: PP34967
    Abstract: A new and distinct variety of Oncidesa plant denominated ‘HONEY MICHELL’ which is with varied floral colors of white, whitish, yellow and yellowish, compared to the parent variety, i.e. HONEY ANGEL. HONEY ANGEL has yellow flowers. The height of HONEY MICHELL is about ? to half to the height of the parent variety, HONEY ANGEL. Therefore, the generated new variety is suitable for the pot plant usage in the oncidium flower market. Compared to other similar dwarf oncidium hybrid orchids, which are planted and sold as ornamental pot orchids, such as Oncidium ‘Twinkle’ or Oncidium ‘Sepia’, they are only similar in plant height, around 50˜70 cm height. The floret size is tiny and floret number is crowded with Oncidium ‘Twinkle’. In contrast, the floret size of ‘HONEY MICHELL’ is bigger (3˜5 cm width), and floret number is relatively few.
