Sea Green Juniper

Juniperus × pfitzeriana 'Sea Green'

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 Sea Green Juniper forms a dense evergreen bush, rising in layers of arching branches to about 6 feet tall and 8 feet wide. It has beautiful foliage in a calming dark green, with just a hint of blue to it. Plant it around your home with other evergreens and foundation plants, or out in beds for height and bulk. It can be trimmed into rounded forms or made into a hedge, and it looks just as perfect growing naturally on slopes and rocky ground.

  • Arching vase-shaped evergreen, almost as tall as it is wide
  • Tranquil dark green foliage with a hint of blue
  • Attractive dense form that can be trimmed if needed
  • Both cold and drought resistant
  • Free of pests and untouched by deer

Plant the Sea Green Juniper in full sun, and in well-drained soil. It grows well in drier soils, including sands, gravels and shallow, rocky ground. Avoid low-lying and wet areas, and plant on slopes if you have clay soil. Once established it is drought resistant, and it grows in both cold and hot parts of the country. Pests and deer normally leave it alone, and diseases are not seen if the soil is not too wet.

We all love color in our gardens, but let’s not forget that green is a color too, and one whose ability to create moods of calm and security is well-known. It is the greens in our gardens that make it a space of tranquility, so when choosing shrubs to decorate your garden with, don’t ignore green, or your garden is in danger of being too stimulating and restless – not at all what we step outside for. It makes sense to keep our larger plants in shades of tranquil green, saving the golds and blues for accents and specimens. Dark greens with just a hint of blue are among the richest of all, and for that, nothing can beat the beautiful Sea Green Juniper. Rising in layers of arching branches, it has a graceful form that is also calming – gaze at it in your garden and you can feel the calm spreading though your body. It grows to around 6 feet tall and wide, so it is perfect anywhere you want a larger plant around your home or out in the garden. It needs virtually no care – a calming thought in itself – so use it freely to fill your beds with its simple beauty.

Growing the Sea Green Juniper

Size and Appearance

The Sea Green Juniper is an evergreen shrub that in about 10 years will be 4 to 6 feet tall, and 6 to 8 feet wide. Don’t be misled by a young plant, which will be low and spreading. It will add height after just a few years, and develop into a substantial bush, that could eventually reach 8 feet tall and 10 feet or more in width. Allow plenty of room for its growth when choosing a planting spot. It grows with layers of arching, semi-horizontal branches, creating a fountain or vase-like appearance, with foliage to the ground. Only on very old bushes, or if you prune it to reveal them, will the stems, with their attractive reddish-brown, peeling bark, be visible. Older stems turn pewter gray.

Juniper bushes have two kinds of leaves – small triangular pointed ones that grow out from the stems, called juvenile leaves, and flat, scale-like ones that cling to the stems tightly, called adult leaves. The Sea Green Juniper has both types, with more juvenile-type leaves on the lower parts. This gives the plant a softer, more bushy look than we see in other junipers that only have scale-like leaves. The color of the foliage is dark green, with bluish overtones, but still distinctly green, and this is a very attractive shade for giving weight and substance to your planting arrangements.

Using the Sea Green Juniper in Your Garden

Although it may take a little time to build the height, this juniper is an excellent choice for foundation planting around your home, where its fine, softer texture contrasts well with bushes that have broader leaves. Use it out in beds as a background shrub, or plant it on slopes, or in rocky areas, where it will look very effective. Some junipers are best left untrimmed, but the Sea Green Juniper works well either way, and it can be successfully trimmed into hedges and more formal, neater shapes.

Hardiness

The Sea Green Juniper is very hardy, thriving in zone 4, and growing in all the warmer zones too, all the way into zone 9. It grows well in arid regions as well.

Sun Exposure and Soil Conditions

Full sun is the best location for this plant, as shade will produce weaker, more open growth. The soil should be well-drained, but beyond that anything goes. Sandy soils, gravels, rocky and shallow soil – all these are acceptable, and so are urban soils and areas of new construction. Regular garden soil and even heavier clay soils are also fine, if they are not wet. If you have heavy soil, choose a sloping or higher location, to give the drainage needed.

Maintenance and Pruning

Once it is established the Sea Green Juniper is drought resistant and tough. It normally has no pests, and if you avoid wet areas it should have no diseases either. Deer leave it alone, so it needs no care, and it definitely falls into the ‘very low maintenance’ category.

It can be trimmed into a broad hedge or rounded form, and also trained into poodle and pom-pom forms, where it will develop good dense foliage. Trim as needed, from spring to fall, or at any time in hotter zones.

History and Origin of the Sea Green Juniper

The origin of the Sea Green Juniper is a bit of a mystery. It is normally considered to be a form of the Pfitzer juniper, Juniperus x pfitzeriana. That plant is a hybrid between two other junipers, the Chinese juniper, Juniperus chinensis, and the savin juniper, Juniperus sabina. Although a hybrid, it is a natural one, and not man-made. It was found growing wild in Inner Mongolia in the 19th century and in the 1890s identified and named at the Späth Arboretum, in Berlin. Other experts think it could be a form of the Chinese juniper, or even a different hybrid, as it is more upright than other forms of the Pfitzer juniper. It appeared in nurseries in the 1990s, but where it came from is something that has been lost. Still, whatever its origins, ‘Sea Green’ is a valuable garden plant that gardeners around the world enjoy.
