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.

Nothing 'lesser' about it, the Ralph Shugert Periwinkle (Vinca minor 'Ralph Shugert') may be considered a Lesser Periwinkle, but its brilliant evergreen color will more than make up for its botanical status!
Let Ralph Shugert Periwinkle add visual interest with beautiful blue-violet flowers that are larger than other varieties! Support the nectar needs of butterflies and beneficial pollinators just as the growing season gets started once again.
The plants will bloom through the summer and even into fall. You'll also appreciate the dark, glossy green variegated foliage that displays a white margin around each leaf for a fanciful appearance!
Butterflies love the blooms, but rabbits and deer tend to steer clear. No wonder it was selected as the winner of the esteemed Award of Garden Merit. The Royal Horticultural Society judged it for both its ornamental qualities and its high performance!
Planting and Application:
Put your best foot forward with this virtually carefree groundcover. Ralph Shugert Periwinkle brings a sophisticated, soft polish to the lowest layer of your planting beds. Use this well-behaved variety at the top of retaining walls to soften the look and blur the hard line of transition.
Use Ralph Shugert in all of your flower beds as a consistent design element. This trailing evergreen ties the look together, and thrives in full sun to partial shade. Tuck several into your seasonal containers to "Spill" over the edges in a delightful presentation worthy of Instagram. Include them in raised beds, too, and you'll gain a restful modern look.
This effective groundcover grows into a dense mat to help suppress weeds. Underplant your Landscape Roses for a dynamic look all season long that requires little care! Put these plants to work for erosion control on slopes and embankments...or to fill wide, open areas with durable color. Rugged Periwinkle can be mowed after blooming to help keep the ground cover thick and weed-resistant.
- Cornflower Blue Blooms in the Early Season
- Flowers Keep Coming Through the Fall
- Showy Evergreen Leaves are Dark Green with White Margins
- Low-Growing, Trailing Habit - Great In Containers & Hanging Baskets
- Creates a Colorful Carpet That Suppresses Weeds
#ProPlantTips for Care:
We recommend that you add Nature Hills Root Booster during planting. This time-tested formula creates a symbiotic relationship with the tiny feeder roots and helps them access micronutrients from the soil. Vinca does best and has the best foliage coloration in full sun in cooler climates, but in hotter climates of USDA planting zones 4 to 9, Vinca appreciates part shade or afternoon shade. Provide a well-drained area with regular moisture access for new plants while they are becoming established, but once they have settled, they become rather drought-tolerant! Trim back any winter dieback after flowering in the spring, but you can shorten up wayward tendrils at any time.
Nature Hills loves plants and is dedicated to keeping your local ecology safe! That's why we use Plant Sentry™ software that helps ensure regulated plant material isn't shipped to prohibited areas. Count on our expertise in growing and shipping plants, while following every state and local regulation. Type in your Zip Code above the Plant Highlights to see if you can grow this desirable selection in your area without worry.
