How to Grow Anise Hyssop
Agastache foeniculum
Anise hyssop has been grown for centuries for its medicinal qualities but it also attracts pollinators and repels deer. Perennial in USDA zones 4–8.
Anise hyssop is a tender perennial herb that can be used to great effect in the landscape and harvested for medicinal uses. It is a pollinator magnet. It reseeds easily so will naturalize if you let it. Choose a location in your border to let it flourish and discourage deer and rabbits.

✦ It grows wild in northern regions of North America, sprawling across open prairie land and creating vast stretches of lavender blossoms from June to September.
✦ Mature heights are between 2-4 feet with a spread of 1.5-3 feet. True statement plants with a bushy growth habit and towering purple spires of flowers that will usually be covered in bees.
✦ Also called fragrant, lavender, or blue giant hyssop, this is an aromatic herb. The leaves have a refreshingly sweet smell and taste, like a combination of anise, licorice, and mint. The flowers themselves have no aroma. The leaves and flowers make a refreshing, fruity tea, and can be added to salads.
✦ Sometimes called hummingbird mint as it appeals to hummingbirds and other pollinators with a long proboscis that are drawn to the nectar-filled towers.
✦ If you want a lot of this eye-catching herb, it’s easy to propagate, divide, and it also reseeds easily.
✦ Once established, you barely have to worry about it. It is part of a water-wise landscape.
Store your seeds in the refrigerator when you get them to help with cold stratification.

A. foeniculum seeds germinate well after exposure to cold and moist conditions. This process is called cold stratification.
The best way to start seeds is to sow them directly into the garden in early fall, so they can experience natural cold stratification during the winter months. In Austin, we do this in October.
Unlike many seeds, those of A. foeniculum need light to germinate. Moisten the soil and sprinkle them on top about three inches apart, then gently press them down.
Keep the soil moist over the winter months, watering just before it completely dries out.
In the spring, the seeds will sprout.
When the seedlings have at least two sets of true leaves and are fairly sturdy, thin them to a distance of 1.5-2’ apart to give them lots of space to reach their full size.
Tips for Growing Anise Hyssop
• Like wildflower seeds, poppies, and nigella, you’ll sow these seeds in the fall so they will go through the winter outside & the cold stratification that will initiate sprouting in the springtime.
• It likes slightly acidic to neutral soil so if you live in an area with alkaline soils, let your hyssop patch be where you throw out your old coffee grounds and tea bags.
• Deadhead old flowers or after the first flush of blooms, cut the plant back by a third to encourage rebound growth
• Expect wilting during periods of transition, but know that plants will soon rebound.
Companion Planting
Anise hyssop grows pretty large so you don’t want it to directly compete with your flowers and vegetables. It will attract bees and pollinators and is said to repel deer and rabbits so I like to grow it next to raised beds or in the border for the best of both worlds. It looks gorgeous planted next to coneflowers or rudbeckia for a glorious contrast.
PLANT MORE FALL SOWN FLOWERS
Airy foliage with odd blue, white, pink, & mauve flowers. Super cool seed pods. Beautiful cut or dried. Edible seeds.
JOY MAX QUALITIES:
Super easy to direct sow from seed
Despite its delicate appearance, it’s a very tough plant, drought and cold hardy
It creates tons of wonderfully weird seed pods, those you don't harvest can be thrown into areas of the garden you wouldn't mind nigella to volunteer
This mix includes many colors: blue, mauve, pink, purple, and white blooms
The blooms, while incredible, only last for 2-3 weeks so succession sowing is a good idea
This state is known for its wildflowers and now you can cultivate a little patch of the best part of Texas no matter where you are. A great gift, the resealable, biodegradable pouch is filled with seeds from twelve Texas native wildflower varieties and illustrated is by JMJ.
The Texas Forever Wildflower Mix includes: Black-Eyed Susan, Pink Evening Primrose, Fire Wheel, Lemon Mint, Mexican Hat, Plains Coreopsis, Purple Coneflower, Scarlet Sage & Texas Bluebonnet
The resealable eco-kraft pouch measures 4x6” & is filled with 1/2 ounce of seeds.. Sows 350 square feet. Sow in Autumn for Spring blooms except in Grow Zones 1-6, sow in early spring. Clear soil surface prior to sowing and keep damp until seeds sprout for best germination.
California Poppies fill a void or slope with color, and require almost no care, attention, water, or good soil. They do need to be cold-stratified to germinate. Sow in the fall for spring blooms.
JOY MAX QUALITIES:
Easy way to fill a big space with bright, lasting flowers that need no attention.
Unlike taller poppy varieties, the foliage is pretty and they don’t die when it gets hot. Drought & frost tolerant
Bright, Edible flowers
Deer-Resistant
This species is actually a short-lived perennial but is treated as an annual. They will self-sow to some degree, but the range of colors diminishes yearly, so sowing fresh seed is a good idea.
