Agastache hybrida Astello Indigo
Anise Hyssop, Hummingbird mint
The packet of Agastache seeds was almost empty. I found 7 or 8 seeds the size of very, very small specks of dust. Is this normal? PROMESSE DE FLEURS' RESPONSE Regarding the Agastache seeds, they are incredibly tiny and indeed, this is normal.

Description
'Astello Indigo' is a hybrid Agastache that produces beautiful deep, vivid blue flower spikes in summer above dark green, mint-scented foliage. Perfect grown in large clumps in the slightly wilder areas of the garden. Agastache enjoys full sun and cool, well-drained soil. Sow in spring for abundant, long-lasting blooms from summer to autumn.
'Astello Indigo' Agastache belongs to the Lamiaceae family. It is a hybrid perennial variety that is often grown as an annual in colder climates. Agastache hybridizes and self-seeds very easily. 'Astello Indigo' grows to 60 cm high and 30 cm wide. It forms upright clumps of angular stems bearing lanceolate, pubescent dark green leaves with a lighter underside and toothed margins (8 cm long). They give off a pleasant minty aroma. From July to October, beautiful, long flower spikes appear, densely covered with small, tubular bilabiate light blue flowers held in a darker indigo calyx.
Agastache 'Astello Indigo' is a vigorous plant that is easy to grow and fairly hardy, withstanding light frosts of about -7°C. It looks wonderful in natural, informal settings and cottage gardens alongside catmint for instance. Agastache is a valuable honey plant, producing large amounts of nectar for bees and butterflies alike. In the herb or vegetable garden, it can be grown with thyme, savory, chervil or basil. The dried flowers keep very well in bunches. The dried leaves are traditionally used in herbal teas or as a mint substitute for cooking.

Planting and care
Sow from February to April at 15-20°C in good quality soil and cover with a fine layer of compost or vermiculite. Keep the soil moist but not soggy and make sure to give the seeds enough light to germinate. To speed up the process, place in a propagator or place the seed tray inside a polyethylene bag until germination (30-90 days).
When the plants are strong enough to handle, transplant them into pots and move them to a cooler place until they are ready to taken outdoors. When all risk of frost is over, harden them off for 7 to 10 days then plant them out in a sunny location with fertile, well-drained soil. Make sure to leave about 60 cm between each plant.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).
