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


Royal Purple Lily Turf is a remarkable ground-cover plant for filling the spaces beneath your trees and shrubs. Create a rich garden look with layers of plants from tree-top to ground level. This plant has narrow, strap-like, glossy leaves of a rich purple color, and spikes of deep blue flowers decorate it from late summer through fall. It will slowly spread, without becoming weedy or invasive, to form a beautiful carpet a foot or so tall, all across your beds. It can be used as an edging plant along shrub or flower borders, or planted alone to fill awkward corners of your garden, or in pockets among paving. It can also be grown in large planters, beneath taller plants, to create permanent planting instead of time and money consuming annual flowers. It grows equally well in full sun, partial shade or full shade.

  • Outstanding ground cover for sun or shade
  • Rich purple-colored grass-like leaves
  • Resistant to heat, humidity and drought
  • Very easily grown, from full sun to deep shade
  • Pest and disease free, deer-tolerant too

Plant the Royal Purple Lily Turf in any soil, from sand to clay. It grows best in neutral or acidic soils. Water regularly when newly planted, but established plantings are drought resistant. This plant grows well in hot, humid areas too, and it is hardy from zones 6 to 10. It will even grow in sheltered spots in zone 5. It has no significant pests or diseases, it is resistant to deer, and once established it will block the growth of weeds. The only care needed all year long is to clip or mow it in late winter or early spring, to remove the old growth and flower stalks. Fresh new leaves will quickly emerge to bring back a rich, purple ground cover.

As your garden develops, or if you have moved into a home with an existing older garden, there is no way to avoid shade. Trees and shrubs grow – as they should – and soon turn the ground beneath them into shady areas. Often our shrubs and trees grow close to the ground, so there is no room even for shade-tolerant shrubs, and very little else will grow in these places. We have few choices – leave the ground bare or covered with mulch, or find a suitable plant that will grow and spread. These plants, called by gardeners ‘ground covers’, are valuable in every garden, and give a richness and ‘finish’ to the garden that bare earth or mulch cannot do. They also block the growth of weeds, and bring color and interest at seasons when nearby woody plants have less interest.

There are several plants used by gardeners for ground-cover, but one of the most outstanding is lily turf, also known as monkey grass, or border grass. These plants are neither lilies or turf grasses, but they make excellent substitutes for a lawn in shady spots. These are wonderful plants for growing in the shade beneath shrubs, along the front of a shrub border in sun or shade, or for a low-growing and low-maintenance cover over any area of your garden. Of all the varieties of Liriope, Royal Purple Lily Turf stands out for its wonderful and unique coloring, making it a great choice for many places around the garden.

Growing Royal Purple Liriope

As the name suggests, this variety has rich purple foliage, which grows in dense tufts, reaching 12 to 18 inches tall, with glossy, arching, strap-like leaves no more than one inch wide. Clumps will spread at a moderate pace to fill the spaces in between, forming a continuous carpet of foliage. This is not an invasive plant, but it will fill an area with dense leaves, blocking the growth of weeds and making a colorful and very attractive carpet across the ground. To create a continuous ground-cover, place plants about 12 inches apart in all directions. Avoid straight lines, and scatter the plants across the area you want to cover.


In late summer and early fall, flower spikes appear. These rise several inches above the foliage. Royal Purple Lily Turf is among the showiest of these plants when in flower, with the dense flower spikes carrying deep blue flowers. These, with the deep purple leaves, make a beautiful contrast beneath shrubs and small trees – Japanese Maples for example – with rich yellow, orange and red fall foliage. After flowering, the flowers may become black berries, and these interesting spikes often continue to be attractive well into the winter.


Royal Purple Lily Turf grows well from the mild areas of zone 6 all the way into the almost tropical areas of zones 9 and 10. It will also often grow in a sheltered spot in zone 5, but there it will lose its foliage in winter, re-sprouting again in spring. In the warmer areas the foliage persists all winter, looking beautiful and adding interest. To keep beds at their most attractive, clip with shears or run a mower, set high, over your lily turf in late winter or early spring. This is all the attention needed – a truly low-maintenance plant you will love.

Soil Conditions

Plant Royal Purple Lily Turf in all kinds of soil, from sand to clay, and it prefers neutral to acidic soils. It does not grow well in strongly alkaline soil. It happily tolerated heat, humidity and drought, and thrives in many different areas from full sun to full shade, preferring partially-shaded areas. It has no pests or diseases of any significance at all. It is even resistant to deer, and very rarely grazed by them in winter. Lily turf truly is an easy plant to grow, and it makes an excellent ground-cover anywhere in your garden.

History and Origins of the Royal Purple Liriope

Lily turf, Liriope muscari, is a plant that grows naturally in Japan, Korea and all across China. There it is found in open woods and in rocky places. The natural plant has green leaves, but since its introduction into the southeastern USA in the late 19th century, many varieties have been developed. ‘Royal Purple’ is a well-established variety that has proved its value in gardens for many years, but its exact origins have been lost. Our plants are formed by dividing clumps of correctly-named plants, and growing them on. Avoid cheaper plants simply called lily turf, as these will almost certainly be grown from seeds, and be unreliable in color and form. They may also be invasive forms that can become weeds in your garden.
