How are the heights measured?
All tree, and nothin' but the tree! We measure from the top of the soil to the top of the tree; the height of the container or the root system is never included in our measurements.
What is a gallon container?
Nursery containers come in a variety of different sizes, and old-school nursery slang has stuck. While the industry-standard terminology is to call the sizes "Gallon Containers", that doesn't exactly translate to the traditional liquid "gallon" size we think of. You'll find we carry young 1-gallons, up to more mature 7-gallons ranging anywhere from 6 inches to 6ft.
How does the delivery process work?
All of our orders ship via FedEx Ground! Once your order is placed online, our magic elves get right to work picking, staging, boxing and shipping your trees. Orders typically ship out within 2 business days. You will receive email notifications along the way on the progress of your order, as well as tracking information to track your plants all the way to their new home!
Why are some states excluded from shipping?
The short & sweet answer is: "United States Department of Agriculture Restrictions." Every state has their own unique USDA restrictions on which plants they allow to come into their state. While we wish we could serve everyone, it's for the safety of native species and helps prevent the spread of invasive disease & pests. We've gotta protect good ole' Mother Nature, after all.
About Me

The Blue Rug Juniper is a top choice where rich coloring all year round, combined with toughness and fast, easy growth is needed. It soon becomes a broad carpet of evergreen foliage, just a few inches tall but 6 to 10 feet across. It will grow 7 to 12 inches a year, soon covering broad areas, or cascading down slopes or over walls. This easy-care plant thrives in the hottest, sunniest places, and it tolerates drought once established. It grows well even in sandy soil, or gravel and stones, and it is excellent for planting among rocks, or beside paved areas and concrete edging. It prevents soil erosion on slopes, and grows well at high-altitudes, as well as right beside the ocean. It is hardy even to minus 40, and yet it grows in zone 9 too. So don’t worry if this plant will grow in your area or not – it definitely will.
- Striking silver-blue low carpeting plant
- Super-hardy to minus 40
- Heat and drought tolerant, even in poor and sandy soil
- Fast growing to cover large areas quickly
- Not eaten by deer, and salt-resistant too
Plant the Blue Rug Juniper in a sunny location in well-drained soil. It will not grow well in shade, or in soil that is constantly damp. It needs no winter protection and it tolerates salt too. Deer leave it alone, and it has no significant pests or diseases. Plant it in groups to cover large areas, or you can use it to soften the edges of paths and driveways, walls and edges. Wherever you grow it, you will love the reliable rich coloring and growth habit of this very popular plant.

When it comes to easy growth in even the most difficult conditions, there are very few plants that can beat the Blue Rug Juniper. This is one of the best garden plants for hot, dry locations, and poor soils – and it thrives in regular conditions too. It doesn’t matter where you live – the north with icy winters; desert areas with hot days and cold nights; hot, dry inland deserts; coastal areas; or the hottest places with little winter cold – this plant is for you.
The Blue Rug Juniper is a fast growing evergreen that forms a low carpet of striking silver-blue foliage over a wide area. It will soon reach 6 to 10 feet across, with its branches spreading in every direction. It stays no more than 6 inches tall, so it really is a carpet of blue over your garden. It grows well on sloping ground, preventing erosion of the soil. It cascades over walls and terraces, or it covers large areas which are so hot and dry that nothing else will grow. It makes the perfect foreground for larger beds of shrubs and trees. This truly is a plant for all gardens.
Growing Blue Rug Junipers
The Blue Rug Juniper is hardy all the way to minus 40 degrees, yet it also grows well in zone 9, where frost hardly ever arrives. At high altitudes, under strong sunlight and sudden temperature changes, it grows well. It will grow in any well-drained soil, and is happy in very sandy soil, or gravel and rocky soils too. Most gardens have hot, sunny areas, such as alongside a driveway, or by a curb, where reflected heat from hard surfaces often creates difficult hot conditions. Through it all, the Blue Rug Juniper looks great, with dense, silvery-blue foliage all year round. It grows by sending out long stems, which then branch sideways to develop a thick, low carpet.
The Blue Rug Juniper is normally completely free of pests or diseases. Do not plant in shady areas or damp soil, as this plant needs plenty of sun, and well-drained soil. It is not eaten by deer, so you can plant even where they are found. It is resistant to salt-spray, and since it loves sandy soil it is ideal for the beach-front cottage. It is also rarely affected by road-salt in winter, so it can be planted along driveways too. Very few plants are a tolerant and versatile as this one.
Where to Plant Your Blue Rug Juniper
Because if its wide-spreading habit, remember to allow enough room when planting. For a ground-cover over a large area, plant on 4 to 6-foot centers. To soften the edges of a terrace or driveway, plant 2 feet back from the edge, so that you don’t need to trim. It is possible to trim back over-long branches. Simply cut back to just after an upward-growing shoot, and the cut end will never show. New side-branches will soon appear and thicken the growth of your plants.
Creeping Juniper (Juniperus horizontalis) is an American native plant, found growing all across north America, from Alaska to Maine. It grows south into Montana and Illinois, as well as across Canada, from east to west, and up into the Arctic. It is a variable plant, in growth pattern and in its foliage coloring, and many forms exist.
Origins of the Blue Rug Juniper
In 1914 Jacob van Heiningen, who lived in Connecticut, found a unique form growing on the island of Vinalhaven, Maine. Jacob had originally come from Holland, and he started a successful and important nursery in the town of South Wilton, in rural New England. So he was interested in plants, and saw the potential of this colorful juniper, which has become one of the most popular and reliable of all garden conifers. He also had a sense of humor, and called his plant ‘Wiltonii’, after his town, but also after Wilton Carpets, a famous brand of dense wool rugs from Axminster, England. Over the years most people came to call this plant the Blue Rug Juniper, keeping the spirit of Jacob’s original joke.
