Petunia
Petunia
One of the most popular bedding plants, blooming in nearly every colour from late spring to frost in beds, baskets and pots, and spreading kinds carpet the ground or cascade over walls. Butterflies and hummingbirds visit. Give it sun and well-drained soil, pinch leggy stems, and keep the leaves dry at night.

Spacing
VeraScape spaces plants so their grown canopies just touch. For Petunia, that’s about 3.5 ft apart, center to center.
Place a row in your own yard and VeraScape spaces them at their mature width, so you can see whether they’ll crowd the walk.
