Amazon™ Neon Duo Dianthus

Amazon™ Neon Duo is an interspecific Dianthus selection identified by PanAmerican Seed as PAS97395. The breeder lists an upright habit, sun exposure, an 18–36 inch height, a 10–12 inch width, and hardiness zones 5a–9a on its [Amazon™ Neon Duo Dianthus product page](https://www.panamseed.com/Products/022500048011376/dianthus-amazon-neon-duo/). The product is a mix of Neon Cherry and Neon Purple. ## Flowering and size PanAmerican Seed lists flowering from early spring through late spring, summer, late summer, and autumn. The stated height and width are ranges, and its spacing guidance is 10–14 inches. The blend brings both named shades into a flower bed or bouquet. The breeder also presents Amazon for summer bouquets and cut-flower production. ## Garden placement Choose a sunny place and allow the listed spread for airflow and growth. Its upright form and cut-flower use suit a sunny border or dedicated cutting bed. ## Maintenance For general Sweet William garden care, the [Royal Horticultural Society](https://www.rhs.org.uk/plants/105495/dianthus-barbatus/details) recommends full sun, well-drained soil, and deadheading as needed. The breeder identifies these Amazon selections as Dianthus barbatus interspecific; use that guidance as general species-context care.
