The scent of licorice on the breeze, a haze of violet-blue spikes swaying in the July heat, and the hum of bees working each tiny floret — that is the promise of a well-placed Agastache. For many gardeners, the challenge isn’t finding a plant, but finding a specimen that brings that vision to life without a year of fussing. Whether you need a reliable perennial to anchor a border or a pollinator magnet for a new patch, the difference between a dried-up plug and a thriving clump often comes down to the first purchase.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. I study supplier catalogues, compare germination data from seed trials, and dig through hundreds of verified buyer reports to pinpoint which live plants and seed packets actually deliver on their tagline.
This guide cuts through the hype to help you pick from the top contenders for a little adder agastache, focusing on the plants and seeds that earn their spot in the ground.
How To Choose The Best Agastache
Agastache is a forgiving genus once established, but the first step — picking the right starting point — makes or breaks your season. The two main paths are live plants, which give you an instant clump, and seeds, which require more patience but offer variety. Below are the key factors to weigh before you click add to cart.
Live Plant vs. Seed: What Fits Your Timeline
A live perennial in a #1 container can bloom in its first summer, giving you immediate color and pollinator activity. Seeds, particularly anise hyssop, need cold stratification or a long growing season to reach flowering size and often won’t perform until year two. If you want a mature look by July, prioritize a rooted plant over a packet.
Hardiness Zone Compliance
Many Agastache hybrids are restricted to certain USDA zones — some sellers won’t ship to states like CA, OR, or WA due to agricultural regulations. Always confirm that the specific cultivar (e.g., Agastache x ‘Blue Fortune’) is legal and viable in your zone before ordering. A plant that looks healthy on delivery will fail if your winter lows drop below its tolerance.
Container Size and Root Development
A #1 container plant should have a dense, but not pot-bound, root system. If the roots circle the pot tightly, the plant may struggle to establish after transplanting. Purchasing from a nursery that packs the pot with moist soil and protects the foliage during shipping is a strong sign you will receive a specimen ready to thrive.

In‑Depth Reviews
1. Perennial Farm Agastache x ‘Blue Fortune’
This is the quickest path to a mature, flowering clump in your garden. ‘Blue Fortune’ is a tried hybrid that sends up dense, deep blue spikes reaching 2 to 3 feet tall from July into September. The fragrant green foliage stays compact and bushy, making it a strong anchor for a sunny border. Buyers consistently praise the robust root system and the careful packaging — the oversized box and moist soil suggest the nursery takes shipping seriously.
The plant arrives fully rooted in its #1 container and is ready for immediate planting. It resists deer and draws butterflies and hummingbirds heavily. If you want a specimen that looks like it came from a local nursery rather than a mail-order gamble, this is it. A few customers noted that plants shipped between November and March may arrive dormant and trimmed, which is normal for bare-root season but can be surprising if you expect full foliage.
Because the plant is an established perennial, you avoid the stratification and germination wait that seeds require. The only structural limitation is the restricted shipping list — this seller cannot ship to AK, CA, CO, ID, MT, NV, OR, UT, WA, or HI due to agricultural rules. If you live in those states, you will need to pivot to the seed options below.
What works
- Established root system provides first-year blooms.
- Exceptional packaging protects foliage in transit.
- Strong deer resistance and high pollinator attraction.
What doesn’t
- Cannot ship to several western states due to USDA restrictions.
- Dormant winter shipments may look sparse on arrival.
2. Perennial Farm Agastache x Kudos ‘Yellow’
If your space calls for a shorter, golden accent rather than a tall violet spike, this is the refined choice. The Kudos series was bred specifically for compact habit, large dense inflorescences, and improved mildew resistance. The plant tops out around 24 inches, with gray-green foliage that releases a pleasant fragrance when brushed. It softens the transition between orange coneflowers and coreopsis beautifully.
Buyer feedback highlights the thick stems, full leaves, and strong fragrance upon arrival — a sign of a healthy, actively growing plant. The nursery packs the pot securely, and the soil stays moist during transit. Like the ‘Blue Fortune’, it must be planted in full sun with well-drained soil, and it shares the same shipping restrictions to several western states.
One buyer in a colder zone reported that their young plug did not survive the winter, which underscores the importance of matching your hardiness zone to this hybrid. For warmer zones and situations where you need a lower, neater form that still pumps out bright gold blooms for hummingbirds, this plant fills the gap perfectly.
What works
- Compact 24-inch habit fits smaller borders and containers.
- Excellent mildew resistance compared to older varieties.
- Strong fragrance and dense flower spikes.
What doesn’t
- May not overwinter reliably in colder zones without protection.
- Restricted shipping to several western states.
3. Everwilde Farms Anise Hyssop Seeds 1 Oz
For gardeners who want to cover a larger area or simply prefer starting from seed, this one-ounce packet delivers a robust quantity of non-GMO, open-pollinated seeds. The resealable triple-layer mylar bag keeps the seeds viable for seasons to come — a practical detail if you plan to stagger your sowings. The species is Agastache foeniculum, a true native North American perennial that grows 2 to 4 feet tall with the classic licorice scent.
Reviews consistently mention fast germination — some buyers report sprouts in as few as three days with proper warmth. The instructions are clear, and the QR code links to additional support. However, a small number of buyers experienced zero germination, often because they missed the cold stratification step or sowed in conditions that were too cool. This seed performs best when cold stratified for a few weeks before spring sowing or direct sown in fall.
The main trade-off is the same as any seed-starting venture: you are waiting a season for the plant to mature. If you want flowers by midsummer of the first year, the live plants above are a better fit. But if you have the patience and want to fill a prairie or a large wildflower patch without breaking your budget, this bulk packet is hard to beat.
What works
- High-quality, fresh seeds with fast germination reports.
- Resealable mylar packaging preserves viability.
- Great value for large-scale or wildflower installations.
What doesn’t
- Requires cold stratification for best results — not a direct-sow-only option.
- First-year bloom is unlikely if started in spring.
4. Seed Needs Anise Hyssop Seeds (5 Packs)
This five-packet bundle is an entry-level option for those who want to test anise hyssop in multiple spots or share seeds with friends. Each packet contains a generous quantity of untreated, open-pollinated seeds. The packaging includes an artful illustration on the front and detailed sowing information on the reverse, making it beginner-friendly. Many buyers reported seeing sprouts within a week, especially when using a grow light or starting indoors.
The variety is Agastache foeniculum, the same native species as Everwilde’s, so the eventual plant size and flowering habit are nearly identical. The seeds are stored in a temperature-controlled facility and packed in moisture-resistant material, which should keep them fresh through the current and following growing season if stored properly after opening.
The most significant concern is the occasional review citing zero germination. While this can happen with any seed lot — and some of the failures may be due to user error — it is worth noting that Seed Needs packets are individually smaller in total seed count than the bulk ounce from Everwilde. For the price, you get five separate packets rather than one large bag, which is convenient for sharing but delivers less total seed mass per dollar.
What works
- Five separate packets allow for easy gifting or staggered planting.
- Heirloom, non-GMO seeds with clear sowing instructions.
- Good germination speed in warm indoor conditions.
What doesn’t
- Occasional reports of zero germination from certain lots.
- Less total seed mass compared to a single bulk ounce packet.
5. Earth Science Wildflower Butterfly & Hummingbird Mix 6 lb
If your goal is a low-maintenance, meadow-like patch rather than a single species, this 6-pound mix is an all-in-one solution. It combines a blend of annuals and perennials — zinnia, cosmos, Shasta daisy, sweet William, black-eyed Susan — with granular plant food and soil conditioners. The idea is to scatter the granules onto prepared soil and let the combination of seed and fertilizer work together without separate amendments.
The mix contains Agastache foeniculum (anise hyssop) as one component among many, so it is not a dedicated hyssop product. Buyers who want a monoculture of ‘Little Adder’ should look at the individual seed or plant options above. However, for a gardener who cares more about attracting hummingbirds and butterflies than about a specific species, this bag simplifies the whole process. One reviewer noted that the product has a strong, unpleasant odor due to the fertilizer, which is a temporary trade-off for the convenience.
Results are mixed: some customers report a stunning bloom show, while others saw nothing at all — likely because the mix is sensitive to planting conditions (proper soil contact, consistent moisture, and timing). With 6 pounds of material, you can cover a large area, but the risk of low germination in poor soil is real. This product is best for those with a forgiving patch of earth and a relaxed aesthetic.
What works
- All-in-one formula with seed, food, and soil conditioner.
- Large coverage area for budget meadow projects.
- Attracts a wide variety of pollinators.
What doesn’t
- Not a pure Agastache product — anise hyssop is only one ingredient.
- Strong smell from the fertilizer components.
- Germination can be inconsistent depending on soil prep.
Hardware & Specs Guide
Hybrid vs. Native Species
A major fork in the road is choosing between a hybrid cultivar (like ‘Blue Fortune’ or Kudos) and the straight native species (Agastache foeniculum). Hybrids tend to offer more compact habits, denser flower spikes, and specific disease resistance, but they often have restricted shipping zones and may not be as cold-hardy. Native anise hyssop is more forgiving across a wider range of climates and is the preferred choice for naturalized meadows.
Cold Stratification for Seeds
Anise hyssop seeds benefit from a 30-day cold stratification period to break dormancy. Place the seeds in a damp paper towel inside a sealed bag, store in the refrigerator, then sow in spring. Skipping this step is the most common reason for zero germination. Some sellers pre-chill their stock, but always check the packet instructions — if no stratification is mentioned, assume you need to provide it yourself.
