Each perennial has it owns requirements. Anise hyssop (Agastache foeniculum) is a perennial in zones 5 to 9. This is a very fragrant licorice tasting herb you will want to place at the back of your garden as it can reach up to four feet in height. These plants like moist, well-drained soil in a sunny location but will tolerate a drier area and some light shade. You can direct sow after the last frost date for your area. Otherwise you will need to start them indoors and transplant them out after the last frost date. Slugs love the little baby plants so be ware! They germinate quite easily and I have had new seedlings "volunteers" come up the next season around the "mother" plants. This makes a great tea!
The seeds can be directly sown into the ground in very late Spring or early Summer (when soil is warmed) and prefer the same sort of conditions as Rosemary and Thyme - well drained soil in a sunny spot. It can be planted into pots, with well drained potting mix, in a warm, sunny position.
Thin to 30cm/12" apart. Trim older plants regularly, to keep them compact. Trim in Spring and after flowering to maintain a compact shape.
Feed the plant well, during flowering.
Hyssop will self-seed on light well drained soil in a warm spot. `Perennials` is a broad term, and many are so easy from seed in early Autumn. Once established, very many perennials self-seed prolifically when soil conditions are right.
