🌸 About the Plant

Dendrobium Thongchai Gold is a hybrid orchid in the genus Dendrobium, bred in Thailand. It’s a sympodial / cane-type orchid hybrid known for its bright golden-yellow flowers often with a contrasting lip (usually purple or reddish), giving the blooms a striking and attractive look.

Botanical background:

• Genus: Dendrobium

• Grex/Hybrid name: Thongchai Gold — usually a cross of Den. Jiad Gold × Madame Uraiwan registered in the early 1990s.

• Type: Epiphytic orchid hybrid (grows naturally on trees/rocks in wild conditions but perfectly suited to pot culture).

🌼 Flower Characteristics

• Flower Color: Golden yellow petals with a distinct purple / dark lip (can vary slightly in color intensity depending on plant and conditions).

• Size: Medium-sized blooms (often ~4–6 cm or a bit larger depending on cultivar and conditions).

• Inflorescences: Long stems that carry several flowers (often 8–15) in a cluster.

• Fragrance: Generally not strongly fragrant.

(Note: The specific “Viroj” mention appears in some nursery listings as a trade name/variant for the medium size or color form of Thongchai Gold — flower colors and patterns can vary slightly with these nursery variants.)
