Only one thing could make a spreading petunia even more appealing, and this one’s got it; FRAGRANCE! The fragrance has notes of hyacinth, sweet honey and rose and as the name implies, the scent is stronger in the evening hours. It’s a visual sensation too, with brilliant indigo 5 cm (2 in) blooms that billow from baskets or patio containers, and are dramatic when planted en masse. Ht 12-20 cm (5-8 in) and a width of 75-90 cm (30-36 in).
Start seed 8 to 10 weeks prior to intended date of transplanting outside. Press seed into soil as light will aid germination. Germinates best at 24 C (75 F) in 5-15 days. Grow plants to budding stage at 12 C (55 F). Petunias lose dwarf growth habit if grown above that temperature. Fertilize every 2 weeks with 10-52-17 and liquid seaweed for strong healthy plants. Garden spacing 60 cm (24 in) apart. Pinch old flowers off to encourage more bloom.
