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 American Agave is a striking and unique plant that thrives in the driest and hottest locations. It forms a dramatic clump of very large, blue-gray leaves, arranged in a rosette. It will grow 3 to 5 feet tall and up to 10 feet across. It fits perfectly with modern architecture, Spanish colonial-style architecture, in gravel beds and on steep slopes. It never needs watering, even if no rain falls for years. One day, in perhaps 20 years or so, it will send up an enormous flower spike, 15 to 30 feet tall, with large clusters of yellow flowers on it. By that time younger plants will have grown up around it, because after it flowers the plant dies, leaving behind the younger plants to carry on. Allow enough room for this plant to reach its full width, as it has sharp spines, and it cannot be trimmed without destroying its form.

  • Dramatic architectural form
  • Striking steel-blue giant leaves
  • Absolutely drought-proof
  • Grows well by the ocean
  • Ideal for areas that can never be watered

The Blue American Agave is hardy to zone 8, so it can be grown up both coasts and all through the south. It should be planted only in full sun, and in well-drained soil, especially in areas with high rainfall. It never needs watering, or any other care, and it thrives on being left alone to grow in the hottest and driest places. It is salt resistant, and ideal for dry, sandy location near the ocean, as well as in hot dry places, and desert areas too. It has no pest or diseases of any concern, and will not be bothered by deer or rabbits

Plant Hardiness Zones 8-11
Mature Width 6-10
Mature Height 3 – 5 ft. (plant); 25 ft. (flower spike)
Soil Conditions Any well-drained soil
Sunlight Full sun
Drought Tolerance Excellent
Zones 8-11

Finding plants to grow in the driest places has become a necessity in many areas, and for the most drought resistant plants we can turn to the driest areas of America, where plants thrive in deserts and in dry, sandy beach areas. There, from Florida through Texas and into California, you will find the Blue American Agave growing wild in such places.

This plant is not only tough, but strikingly beautiful, making a bold clump of very large, thick leaves clustered on the ground. The mature leaves are 3 to 6 feet long, tapering to a long tip, and up to 2 feet wide at the base. They are thick, hard and fleshy with a series of spines along the edges and a large, brown spine on the tip. They are a very attractive rich blue-green color, with a gray film over the surface. The leaves are arranged in a tight spiral around the center of the plant, where new leaves slowly emerge. The leaves arch over as they develop, so the clump is usually 3 to 5 feet tall overall.

Growing Blue American Agave

The Blue American Agave makes a very handsome specimen in a hot, dry pace, where it can survive and grow in dry soil for months and even years. Water is stored inside the fleshy leaves, to keep the plant alive during extended periods of drought. Over time, young plants will emerge around the original plant, eventually growing into a dense clump of several plants. Eventually, after 20 or 30 years – not the 100 that its name suggests – a very tall flower spike will emerge from the center of the clump. This can be 2 feet thick at the base, and will grow up as much as 30 feet, although 15 to 25 feet is more usual.

All up the upper half of its robust stem, flowers shoots will emerge, and each one can be 3 feet long, carrying many yellow, cup-shaped flowers 6 to 8 inches long. After the flowers fade, large seed capsule are formed, each 2 or 3 inches long. Eventually, as the seeds ripen, the stem and the plant it came from will die, but by that time the other plants in the clump are ready to take over, and the dead plant can be removed at ground level.

Hardiness

This is a striking and architectural plant that is perfect for dry gardens, in the hottest, sunniest places. It is hardy to 10 degrees, so it will grow outdoors from zone 8 upwards. In those colder zones it will do best in very dry spots, with good soil drainage, where winter wetness is not a problem. It can even be planted underneath overhanging parts of houses, where rain never falls, because it will find enough water from further away.

Uses in Your Garden

It is an appropriate plant for any Spanish-style architecture, as well as in modern, or mid-century styled gardens. It is salt-resistant and grows well in coastal areas and at a beach house. The modern xeric style of water-efficient gardening has embraced this wonderful plant too. Alternatively, it can be grown indoors, in a very large pot, but it will grow very large, so make sure you have enough room for it indoors.

Planting Location

When choosing a place to grow it, apart from sun and good drainage, it must have enough room. Measure carefully and allow at least 4 feet in all directions around the plant. Because of the spines, it should not be placed where it can be a hazard, such as too close to walkways. Since it cannot be trimmed without damaging its appearance, it must have enough room to develop its full width.

Care and Maintenance

The Blue American Agave (Agave americana) is also known as the American Aloe and the sentry plant. However, it is not a true aloe, but in fact a distant relative of Asparagus. As long as this plant is in well-drained soil, even pure sand, and full sun, it will grow well and require almost zero maintenance, except for the very occasional removal of a dead leaf for neatness. It has no pests or diseases, and is not eaten by deer or rabbits. For the perfect low-care, drought-resistant plant, it cannot be beaten.
