Wilsonara Aloha Sparks 'Halloween'
Wilsonara is an intergeneric cross between three genera (Cochlioda, Odontoglossum and Oncidium (Cda. x Odm. x Onc.)). Wilsonara orchids are known for their quick growth habits and reliable yearly flowering. Any fragrance that comes from Wilsonaras is usually a direct result of the Oncidium parent fragrance. Although Wils. Aloha Sparks 'Halloween' is not fragrant, it produces spectacular dark orange blooms in large showy spikes on a more compact plant than is typical.
Plant may vary from pictured. Unless stated, this plant may not arrive in bloom.
