Wils. Aloha Sparks ‘Halloween’ is a bold and highly floriferous Oncidium alliance hybrid known for its dramatic, seasonal-looking coloration and abundant flower sprays. This orchid produces tall, branching spikes covered in numerous small to medium-sized blooms that create a striking, festive display when in flower. Its dark, warm tones and contrasting markings give it a distinctive “Halloween-inspired” appearance that makes it especially eye-catching in any orchid collection.

Mature plants are capable of producing multiple flower spikes at once, resulting in a dense and long-lasting floral show. Its strong blooming habit and unique coloration make it a favorite among collectors who enjoy unusual and high-impact orchids.
