Check Price on Amazon

This is the real deal: a true Agastache x ‘Blue Fortune’ hybrid in a full #1 container, not a mislabeled species. The plant arrives fully rooted in its pot, meaning you get a 2–3 foot perennial ready to produce violet flower spikes from July through September. The compact, fragrant green foliage is bushy and well-branched right out of the box.

Shipping protection is a standout here — reviewers consistently praise the oversized box and internal wrapping that keeps the brittle stems intact. The seller trims dormant plants between November and March, which is standard practice and results in faster spring regrowth. The root system is mature enough to handle immediate ground planting.

Expect flowers in the very first season if planted early enough in zones 5–9. This is the closest you can get to a nursery-grade plant delivered to your door. The only catch is that California, Oregon, and a few other states have shipping restrictions, so check your address before ordering.

While this is Russian Sage (Perovskia atriplicifolia) rather than Agastache, it delivers a very similar look — silvery-green foliage topped with blue-purple blossoms from midsummer to first freeze. You get two plants in 4-inch pots, each 4 to 8 inches tall, from a Midwest grower that emphasizes root development for stronger establishment.

The seller’s “10x Root Development” claim isn’t just marketing — reviewers report healthy root systems that transplant well despite the smaller container size. The plants are non-GMO and neonicotinoid-free, making them safe for the pollinator garden you are curating. The eco-friendly 100% recyclable box is a nice touch.

Keep in mind that these are 4-inch pot starts, not mature gallon plants. They need a full growing season to reach the 4-foot spread this species is known for. If you are patient and have a sunny spot, the value proposition here is strong. The quick-start planting guide is genuinely helpful for first-time perennial buyers.

Agapanthus ‘Blue’ (Lily of the Nile) is not Agastache, but it competes for the same late-spring-to-summer blue flower display. This 1-gallon shrub from Perfect Plants comes fully rooted and ready for immediate ground planting in zones 8–10. The large clusters of aromatic blue blossoms are reoccurring from late spring through midsummer.

Reviewers consistently comment on the root system — it rivals what you would find at a local nursery. The plant ships well with careful boxing, and the green foliage stays upright during transit. For warm-winter gardeners in the South, this is a reliable way to add blue flower mass to borders without waiting for seeds to mature.

The major limitation is hardiness: Agapanthus ‘Blue’ is rated only for zones 8, 9, and 10. If you live in a colder climate, this will not survive winter outdoors. Also, like many flowering perennials shipped in spring, bloom in the first season is not guaranteed if the plant needs to prioritize root establishment.

This listing from Perfect Plants offers the same 1-gallon Blue Agapanthus but bundles a special blend fertilizer and a planting guide. For a beginner who wants instruction alongside the plant, this is a thoughtful package. The blue/lavender flowers are paired with evergreen foliage that stays attractive even when not in bloom.

Shipping quality is a major positive in customer reviews — the elongated cardboard box with internal orientation keeps the plant vertical and undamaged. Multiple 5-star reviewers mention that the plants arrived in better condition than what they find at local garden centers. The 5-pound shipping weight confirms a substantial soil mass.

The catch is that the promised fertilizer and specific planting guide are not always included. A few buyers report that the guide was generic rather than species-specific, and the fertilizer was missing from the package. Also, this item cannot ship to California or Arizona due to state agricultural restrictions. If you are in those states, look at the standard listing instead.

Heuchera ‘Shades of Purple’ is a foliage-first perennial, not a blue-flowering spike plant. Its value in a garden that already contains Agastache is the color contrast: deep purple and maroon leaves provide a dark backdrop that makes the violet ‘Blue Fortune’ spikes pop. The 2-quart pot size is smaller than a 1-gallon but still substantial for a coral bell.

The seller ships directly from their greenhouse, and the plants arrive with healthy, compact growth. Reviewers in warmer zones like Hawaii confirm that the plants handle shipping stress well and establish quickly in partial shade. The expected height of 18–24 inches makes this suitable for the front or middle of a border.

Be aware that Heuchera is not a substitute for Agastache ‘Blue Fortune’ — it does not produce tall blue flower spikes. The color intensity of the foliage also varies with sunlight; shadier spots yield deeper purple tones. If you need vertical blue blooms, this is not the plant for that role, but it complements the Agastache nicely in a mixed perennial bed.
