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


Tuscan Blue Rosemary is a selected form of rosemary which grows into a broad, upright bush between 3 and 6 feet tall, and up to 4 feet wide. The branches reach to the ground, and for large parts of the year the upper stems are covered with beautiful small flowers of a misty blue color. The foliage is needle-like and very aromatic when crushed, and it is used in the kitchen for its distinctive aroma. This plant is hardy from zone 8, and in colder zones it can be grown in a pot and brought into a cool, sunny place for the winter months. It grows in hot, dry places, including coastal areas, and it is resistant to salt spray. Grow it naturally among rocks or gravel, or it can be clipped into hedges and trimmed shapes. It fits into almost any style of garden, but it is essential element in Mediterranean and Xeric gardens

  • Aromatic bush for sunny parts of the garden
  • Grows 3 to 6 feet tall
  • Ideal for rocky soils and hot, dry conditions
  • Collect young branches to use in the kitchen

Grow the Tuscan Blue Rosemary in hot, dry parts of the garden. Water regularly until established, but after that it is extremely drought resistant. It grows well in any well-drained soil, and it thrives in alkaline soils and among limestone rocks. Avoid rich soils and wet conditions. It doesn’t suffer from pests or diseases and this is an extremely easy plant to grow. In containers use a soil for cactus and succulent plants, and a clay pot with drainage holes.

Nothing says ‘southern Europe’ more than rosemary. This Mediterranean shrub finds its way into so many dishes on the table, and the evocative smell that rises when you crush the foliage conjures up real or imagined memories of blue skies, ancient ruins and rugged landscapes. For gardeners it is also a wonderful sun-loving and drought-resistant evergreen shrub that is so attractive and so useful that you want to plant it everywhere. Its blue flowers add a misty aura, and for the best results it always pays to start with the best variety – Tuscan Blue Rosemary.

Tuscan Blue Rosemary grows rapidly into a broad, upright bush, with branches right to the ground, that will be over 3 feet tall. If left untrimmed it could reach 6 feet tall and be 3 to 4 feet across at the base. With trimming it can be kept significantly smaller with ease, so it is versatile too. The stiff branches are covered in small leaves that cling to the stem, and that look like fat pine needles. They are almost spherical, between 1 and 1½ inches long, and just ⅛ of an inch wide. They are dark green, with a roughened texture. The stems are thick at the base, green when young, but developing a dark gray, flaking bark as they age.

When in bloom, the upper parts of the branches are covered in small flowers, which nestle among the leaves. Each flower is small, with two lips like an open mouth, and a beautiful misty blue color. The flowers are attractive to bees. Flowering times are variable – in hot areas plants may flower for months, at any time of year, while in cooler zones most flowering is in spring and early summer.

Growing Tuscan Blue Rosemary Bushes

Tuscan Blue Rosemary is versatile around the garden. It can be planted in beds with other heat-loving shrubs, or by itself in an area of stones and gravel. It can be left to grow into a natural, irregular upright bush, or trimmed to keep it neat, as a specimen or a hedge. This means it can be grown both in more traditional, formal gardens, and also in wilder, natural gardens. There is a lot of interest today in xeric gardening – gardens that never need watering – and rosemary is a perfect plant for this, thriving with nothing at all. It is also a great plant for containers, pots and boxes, so that a plant can be kept near the kitchen door, or in colder areas brought into a sunny, cool space for the winter months.

Planting Location

Tuscan Blue Rosemary can be grown outdoors in all warmer zones, from 8 to 11. It will grow best in drier, well-drained soil. It is very suitable for alkaline soils and in limestone areas, and it grows well in rocky ground. It will also grow in ordinary garden soils, but don’t enrich the soil, or water too much, as wet conditions are harmful to this plant. Plants in containers do best in clay or concrete pots with drainage holes, in soils blended for succulent plants and cactus. Plant in full sun, because rosemary loves hot places, growing well even in semi-desert areas. It also grows well in coastal areas, and it is highly-resistant to salt-spray and ocean mist.

Care and Maintenance

Once established it is totally drought-proof, and older plants will survive months and months of dryness. You can grow rosemary as a natural, un-pruned bush, but it can also be pruned and trimmed into hedges and more formal mounds and cones, in the ground or in pots. If you plan to trim, do it regularly. Plants respond quickly to trimming of young shoots, and re-sprout densely. But if you cut back into older stems plants are slow to recover, and may die, so trim often, but lightly.

History and Origins of the Tuscan Blue Rosemary Bush

Tuscan Blue Rosemary is a form of the rosemary bush, Rosmarinus officinalis. The name means ‘dew of the sea’, from the Latin words, ‘ros’ (dew) and ‘marinus’ (sea), because the plant is found along the seashore. The Latin world ‘officinalis’ means the plant is used for some medicinal purpose. The rosemary bush grows wild all around the Mediterranean Sea, in Spain, France, Italy, Greece, the Middle East and throughout North Africa. It has been cultivated for centuries as a flavoring, a tea, and for medicinal uses, such as improved digestion. Claims are often made for its use for more serious medical problems, but there is no scientific basis for these claims. It is essential in the kitchen for many Mediterranean dishes, and it is used for flavoring everything from breads and salads to roast potatoes and lamb.

Tuscan Blue Rosemary is the classic full-sized rosemary bush for landscape uses. Other forms are often smaller, and much less suitable for regular garden use. Avoid cheaper plants simply labelled ‘rosemary’, and instead go for the best plant available. There is enormous interest in this plant for cooking and for modern gardening, including xeric gardens, so our stock will soon be gone. Order now, because no garden is complete without a rosemary bush.
