Petunia
Petunia x atkinsiana
Petunias are not subtle, but they can soften a bed edge fast when summer finally opens.
Garden timing
Start very early indoors, or buy starts if seed timing is not worth it.
Transplant after frost into edges, corners, or containers.
Plant intelligence
Use on edges or containers; trailing types need room to spill away from seedlings.

Height: 6-18 inches
Spread: 12-36 inches
Germination: 7-14 days

Species and variety notes
Seed-grown bedding types are compact; vegetative spreading types need more edge room.
More controlled than spreading types and easier near vegetables.
Best use: cut and garden display. Tradeoff: match timing and spacing to the rest of the bed.

Cautions
Tiny seed and slow early growth.
Trailing types can smother small seedlings.
