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.

Growing the Morello Agastache
Size and Appearance
The Morello Agastache is a sturdy perennial plant. It dies back to the ground in fall and then returns the next spring to quickly grow to its full size. Within a few years the stems will be reaching about 2 in height. Young plants send up 3 to 8 stems, while older plants send up many more, reaching a spread of about 2 feet. The stems are strong and stand up without needing any staking or tying. The leaves are in pairs along the stems, from the ground up, and each leaf is oval to triangular, about 2 inches long and 1 ½ inches wide, with a softly serrated edge. In cool weather and extreme dryness the green leaves take on rich purple-brown tones which are very attractive. A crushed leaf gives off a wonderful pungent scent of mint and licorice, and it can be used for tea.
The flower stem, which develops at the top of the leafy stem, is way bigger than in other Agastache. It is up to 14 inches long and almost 2½ inches wide. Amazingly, there are up to 700 flowers in that spike (yes, someone counted them). The flowers are in dense clusters circling the stem, making a virtually continuous column of never-ending color. The flowers are slightly more than an inch long, shaped like a flattened bell, and a rich purple-pink to burgundy-rose color. Flowers open in succession, with the first blooms appearing as early as May, and continuing into September. New flower spikes develop to replace the old ones, each one blooming for weeks and weeks. Bees and hummingbirds love the flowers, so get ready to thrill your children with the presence of these wonderful creatures.
Using the Morello Agastache in Your Garden
This tough plant is a real sun-lover, so use it at the front of sunny borders all around your garden. Plant it in front of shrubs that will have bloomed in spring, or in front of evergreens, whose dark color really shows off the bright pink of the Morello Agastache. Plant it in groups across dry areas and on slopes – space plants 15 inches apart for solid coverage. It fits perfectly into a xeric, or low-water garden, and also into natural gardens, since it is a selection of a plant native to North America.
Both cold and heat resistant, the Morello Agastache grows well in zones 9 and 10 and in well-drained soil in areas as cool as zone 5.
Sun Exposure and Soil Conditions
This is a plant for the sunniest parts of your garden, and more than one or two hours of shade will reduce flowering and weaken the plant. Plant it in well-drained soil, even sandy or gravel soils, and avoid wet areas, especially in zones 5 and 6.
Maintenance and Pruning
Pest and disease problems are very rare in the Morello Agastache, and deer avoid this plant too. There is no need to stake and tie it, like many older perennials needs, so it’s very easy to grow. Remove flower stems that have finished blooming to encourage more, and in late fall cut it back to just a couple of inches tall. That’s it – done for the year.
History and Origin of the Morello Agastache
Agastache is a plant in the same family as mint, found mostly in North America, where there are 20 species, but also in Asia, where there is one species. The unusual name is from Ancient Greek, ágan stákhus (ἄγαν στάχυς), meaning “very much (like) an ear of grain“, describing the flower spike. Terra Nova Nurseries, in Canby Oregon is a plant tissue-culture startup success story that began in 1992 in a tiny greenhouse. A big player in the industry today, it is both a plant breeding lab and a producer of plants by laboratory methods. Janet Egger created the Morello Agastache by hybridizing three wild species – Agastache cusickii, a white species natives to Idaho and Oregon; Agastache cana, from New Mexico and Texas, with dark pink flowers; and Agastache pallida, a tall purple variety from Arizona and Mexico. The hybrid plant Janet produced was patented in 2018, with the name ‘Morello’.
