The search for a true purple flowering perennial that survives dry summers, draws hummingbirds all season, and actually returns year after year feels impossible. Most so-called “purple” agastache varieties bloom a washed-out lavender, arrive as weak plugs, or fail to establish. A genuine Purple Haze Agastache delivers dense, fragrant violet spikes on a 3–4 foot frame, but the nursery stock quality varies wildly between sellers.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. After cross-referencing technical specifications with verified buyer feedback, I’ve isolated the five live plants that match the true agastache performance standard for this exact variety query.
Whether you need a pollinator powerhouse for a xeric border or a deer-resistant cut-flower plant that keeps color from July into October, this guide filters out the weak plugs and mislabeled offers to reveal the specimens worth your soil space. You are looking at the definitive analysis of the best purple haze agastache available for home delivery.
How To Choose The Best Purple Haze Agastache
Purple Haze Agastache (typically Agastache foeniculum or a hybrid like ‘Blue Fortune’) is a North American native prized for its licorice-scented foliage and dense purple flower spikes. Buyers commonly confuse it with purple-leafed houseplants or treat all plugs as equal, which leads to bare patches by July.
Prioritize Root-Ball Maturity Over Price
A 2.5-inch starter plug can produce a mature plant, but it requires a full growing season of babying and extra watering to establish. A #1 container (roughly one gallon) is already fully rooted and will bloom in its first summer with standard watering. For the price difference of a single coffee run, choose the larger container — your agastache will hit the ground running instead of just surviving.
Hardiness Zone Matching Is Non-Negotiable
True Agastache foeniculum is winter-hardy in USDA zones 3 through 8. If a seller lists a “purple” agastache that only claims zones 9–10, it is almost certainly a tropical houseplant mislabeled for the search — it will die in the first frost. Check the technical specifications for the hardiness range before adding to cart.
Check for Organic Status on Edible Varieties
Anise hyssop is a culinary herb commonly brewed into tea or added to salads. If you intend to use it in the kitchen, verify that the plant was grown without synthetic pesticides or fertilizers. Organic heirloom certification ensures the leaves are safe to steep immediately after transplant.

In‑Depth Reviews
1. Perennial Farm Marketplace Agastache x ‘Blue Fortune’
This is the specimen that sets the standard. The ‘Blue Fortune’ hybrid delivers deep violet-blue flower spikes on a 36-inch frame, blooming continuously from July through September. Packaged in a full #1 container weighing 3.5 pounds with soil, this plant arrives with a root system mature enough to establish without coddling — multiple buyers reported opening a box with moist, healthy soil and a plant that looked indistinguishable from high-end nursery stock.
The fragrance is a defining trait here. The gray-green foliage emits a sweet anise scent that intensifies when brushed, and the dense flower spikes attract both hummingbirds and butterflies throughout the heat of summer. USDA restrictions apply (Alaska, California, Colorado, Hawaii, Idaho, Montana, Nevada, Oregon, Utah, Washington — check your state before ordering), but for growers in zones 3–8, this is the most reliable path to an established agastache that blooms in its first season.
One reviewer noted the plant is not a monarch host despite appearing in milkweed searches — a fair clarification. This is a nectar source, not a larval host. If you want instant landscape presence with a proven 5-star shipping record and a plant that survives transplant shock, this Blue Fortune is the pick.
What works
- Fully rooted #1 container blooms first year without extra care
- Exceptional packaging with oversized box and protective wrap — no damage in transit
- Deer-resistant foliage keeps plants intact through the season
What doesn’t
- Cannot ship to several western states including CA, OR, WA, CO
- Not a monarch host plant despite visual similarity to milkweed
2. Perennial Farm Marketplace Agastache x Kudos ‘Yellow’
The Kudos series is a dwarf breakthrough. Unlike the towering 3-foot agastache types, this ‘Yellow’ variety stays at 24 inches with dense, large inflorescences that hold their color without flopping. The gold flowers contrast sharply with the typical purple-blue agastache palette, making it a strategic choice for gardeners who want to soften transitions between orange coneflowers and red torch lilies.
Multiple verified buyers described these plants as “incredibly large, healthy” and “packed perfectly.” The fragrance is present but milder than the anise-heavy types, and the mildew resistance built into the Kudos genetics means it stays clean even in humid summer stretches when weaker agastache hybrids develop leaf spot. Deer resistance is strong, which matters for open border plantings.
The only consistent complaint came from a buyer who received small plugs that did not survive a mild winter. This risk appears low — the overwhelming majority of reviews show a thriving, fragrant plant that shipped promptly. If you have a compact border or want a tidy pollinator plant that softens bold hot-color neighbors, this yellow Kudos delivers.
What works
- Dwarf 24-inch stature fits small borders and front-of-bed positions
- Patented Kudos series offers excellent mildew resistance
- Gold flowers provide a rare non-purple agastache option that pairs well with warm tones
What doesn’t
- Cannot ship to several western states including CA, OR, WA, CO
- Occasional smaller plugs may not overwinter reliably in marginal zones
3. Smoke Camp Crafts Organic Anise Hyssop
This is the edible option. Smoke Camp Crafts grows this Agastache foeniculum without synthetic pesticides or fertilizers, certified organic and heirloom — meaning the leaves are safe to steep into tea immediately after the plant establishes. Native to the northern United States and Canada, it is hardy in zones 3–8 and survives winters that kill zone-tender lookalikes.
Buyers consistently praised the packaging. The plant arrived to Arizona in great shape and adapted well after hardening off in shade. Another reviewer noted the lavender-mint flavor was exactly what they wanted for tea blends and fruit salads. The plant spreads over time, filling empty garden spaces with its bright green foliage and delicate purple flower spikes.
The catch is the plug size. Several buyers received plants that were “sprouts barely 2 inches” tall, far smaller than the advertised images. One plant arrived with a tall stalk that browned and dropped leaves. This is a starter plug, not a mature specimen — it needs babying for its first season, and the quality control on size consistency is inconsistent. For the organic certification and the ability to brew your own anise hyssop tea, it is a fair trade at the entry-level price.
What works
- Certified organic and heirloom — safe for direct tea use
- North American native that supports local pollinators and spreads naturally
- Exceptional packaging survives long-distance shipping to hot climates
What doesn’t
- Plug size is often smaller than advertised — expect a 2-inch starter, not a full plant
- Inconsistent quality control; some plants arrive healthy, others struggle immediately
4. BubbleBlooms Purple Passion Velvet Plant
This is not an agastache. Gynura aurantiaca — commonly known as Purple Passion Velvet Plant — produces soft, fuzzy purple hairs on green leaves that create a striking violet shimmer in bright indirect light. It is sold as a houseplant, not an outdoor perennial, and its USDA hardiness tops out at zone 12 while bottoming at zone 6. It will not survive a frost or function as a hummingbird nectar source.
BubbleBlooms earned strong marks from buyers for packaging quality. Multiple reviewers noted the plant arrived “well wrapped very carefully” and “healthy and happy.” The 4-inch pot size gives it a head start over smaller plugs, and the velvety purple texture makes it a legitimate conversation piece for indoor shelves and desks. The seller offers a 7-day warranty, which adds some protection against DOA shipments.
One buyer reported the plant arrived with a persistently wilted look and did not recover. This is the minority experience, but the risk exists with any live plant shipped in colder months. If you want a purple foliage plant strictly for indoor display and you do not need the pollinator function of true agastache, this BubbleBlooms option works as a decorative houseplant. For outdoor perennial use, look elsewhere.
What works
- Unique velvety purple texture on leaves creates a striking indoor display
- Well-packaged by a seller with strong repeat-purchase reputation
- 7-day warranty provides basic protection against transit damage
What doesn’t
- Not an agastache — this is a tropical houseplant, not a pollinator perennial
- Cannot survive frost; strictly indoor or very warm climate use only
5. CTS Air Plants Tradescantia Purple Heart
This is Tradescantia pallida ‘Purpurea’, commonly called Purple Heart — a fast-spreading ground cover that turns deep purple in full sun. Like the BubbleBlooms plant, it is not an agastache and will not produce the tall flower spikes or licorice scent buyers expect from Purple Haze Agastache. It is a trailing succulent-type plant that reaches about 12 inches tall and spreads aggressively by rooting at the nodes.
CTS Air Plants earned high marks for shipping speed and packaging. One buyer was skeptical about ordering plants by mail and was surprised that the plant arrived “more beautiful in person than the picture shows” with no damage. The 4-inch pot size is standard, and the plant propagates easily: just cut a stem and stick it in soil. Indoor growers in New Jersey reported successful flowering even as a houseplant.
The zone limitation is the dealbreaker for outdoor use. Purple Heart is only hardy in zones 9–10. In colder climates, it must be overwintered indoors or treated as an annual. One buyer with extensive Tradescantia experience reported their plant was struggling despite good care. At the budget price point, this is the cheapest way to get a purple plant in the mail, but it serves a completely different function than true agastache.
What works
- Fast shipping with excellent packaging — plants arrive undamaged and moist
- Deep purple color intensifies in full sun; easy to propagate from cuttings
- Lowest entry-level price for a purple foliage plant
What doesn’t
- Not a true agastache — produces no tall flower spikes and no anise scent
- Only winter-hardy in zones 9–10; requires indoor overwintering elsewhere
Hardware & Specs Guide
Container Size (#1 vs. Plug)
The number-one reason agastache purchases fail is undersized root systems. A #1 container holds roughly one gallon of soil (weighing 3–4 pounds) and contains a fully rooted plant that can be transplanted directly into the garden without a hardening-off period. A 2.5-inch plug is a seedling that needs 4–6 weeks of babying in a sheltered spot before it can handle full sun and wind. For immediate garden impact, always choose the #1 container over a plug.
USDA Hardiness Zone Range
True Agastache foeniculum and its hybrids are reliably perennial in zones 3 through 8. If a product page lists a hardiness range that starts at zone 6 or higher, the plant is likely a tropical or tender perennial that will die in the first winter frost. Always verify the USDA zone claim in the technical specifications before ordering — sellers sometimes mislabel houseplants with the search term “agastache” to capture traffic.
