Understanding Plant Options
Nature Hills offers plants in two main formats:
- Container Plants: Grown in pots with soil, sized by container volume and plant age
- Bare Root Plants: Dormant plants without soil, sized by height measurements
Container Plant Sizes

Annuals such as petunias are beautiful but can be a truly tedious addition to a garden as you have to replace them year after year. However, there is a way to have those classic blossoms without the yearly hassle. Wild Petunia ( Ruellia Humilis) is the perfect perennial, offering beautiful blooms and easy maintenance for years after planting!
Each summer, this specimen becomes speckled with lavender colored flowers that closely resemble the cultivated petunias often lining the shelves at garden centers. Although the two flowers are parts of different families, Wild Petunia is a great way to capture the beauty and preserve it for much longer than a single growing season.
The flowers bloom among the plethora of light green leaves that have a unique characteristic. The leaves are covered in a thin layer of short hair. This gives Wild Petunia a rather fuzzy appearance!
Although these flowers are often found growing naturally in prairies or woodland areas, it can be a stunning addition to any garden as an accent piece to a perennial garden. Since Wild Petunias are low growing, they are also commonly used as border specimen or groundcover in rocky portions of your yard.

Whether this plant is grown by itself or as a colony creating a groundcover, taking care of it is a breeze! Wild Petunia grows in dry as well as average soils as long as it is well-draining. It is also extremely tolerant of drought conditions and thrives in full sun or partial shade. The planting placement options are endless!
Wild Petunia is the perfect way to get that annual grandeur without the yearly planting and spending. Not only is it the perfect addition to a wildflower garden, but it's the ultimate plant it and forget it specimen since it requires very little attention to thrive once established.
