GLOBE THISTLE Echinops ritro
A treasured perennial, this hardy plant produces amazingly-blue and completely round and intriguing globes! Flowers attract butterflies, and are excellent for drying. Plants are easy to grow, drought tolerant, disease resistant, and will grow in poor soils. Plants form tidy clumps, and are not invasive.
Hardiness zones: 3-9
Location: Sun or part sun
Seeds per pack: 5
Germination: As with many perennial seeds, these seeds can benefit from a period of moist cold to help them break dormancy. This is done by giving them a cold 'winter' period (artificial or natural), and then a warming to simulate 'spring', and time to grow! Here's how this can be done:
Obtain a planting container that has holes in the bottom for excess water to drain. Place the seeds just under the surface of your growing medium, and water. Place your container in a cold area (but not freezing, perhaps a refrigerator) for 4-6 weeks. Once the cold period is completed, place the container at room temperature for them to germinate. Be sure to keep the soil moist during this entire germination period. Seedlings will sprout a few weeks, or occasionally several months, after the warming period.
If you are planting your seeds in late winter or spring, these seeds can be planted outdoors while it is still cool out (once the ground is workable and unfrozen), to receive the cold period naturally in the garden.
