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
Container sizes indicate plant age and growing capacity rather than liquid volume equivalents. Our containers follow industry-standard nursery "trade gallon" specifications, which differ from standard liquid gallon measurements.

Important Notes

- Age Indicators: Container size primarily indicates plant age and maturity rather than liquid volume equivalents
Growing Conditions
- Plant size can vary based on variety and growing conditions
- Container size helps indicate plant maturity and establishment level
- Larger containers generally mean more established root systems and faster landscape establishment
Seasonal Availability
- Bare root plants are available seasonally when dormant
- Container plants are available throughout the growing season
- Specific varieties may have limited availability in certain sizes

A Hardy Petunia That Blooms All Summer
Petunia Supertunia Citrus is a unique Petunia with a dark yellow center with light yellow edging.
Yellow has traditionally been a weak color for petunias, but this selection is extra vigorous, producing loads of creamy-yellow blooms all summer long!
Fertilize often for best performance. Supertunia is a long time favorite of growers and gardeners. They're virtually maintenance free and bloom continuously throughout the season. They have large blossoms that attract butterflies and hummingbirds.
Petunias are ideal for baskets, beds, balconies and combination plantings. They are very heat and drought tolerant once established in the ground or pot. They do not need to have their dead flower heads removed to continue flowering and they are not leggy.
'Supertunia® Citrus' has a great yellow color that looks good with just about anything, but looks especially spectacular with blue Salvia or red-and-yellow Bloodflower. For a stunning and colorful garden bed, plant several of each!
This plant can be a perennial in zones 9-11. In zones 3-8 it is an annual only.
- Creamy Yellow Flowers
- Great Performer
- Extra Vigorous Petunia
