Globe thistle is part of the Echinops genus and its scientific name is Echinops ritro.

This plant is resistant to deer, and rabbits and attracts bees, hover flies, butterflies, and other beneficial insects and pollinators to the garden.
The stems are tall, erect, grooved, hairy and hollow. The leaves are spiky and thistle like but hairy and not as tough as wild thistle.
The flowerhead opens at the top of the stem and consists of many smaller florets arranged in a perfect sphere. The colours range from purple though blue to steely grey.

This plant self-seeds freely, to prevent this deadhead immediately after the flowers are spent. This will also encourage a second flush of blooming.

Doesn’t care to be transplanted or divided, so after its planted, leave alone as much as possible.

It is a flower / ornamental and is treated mainly as a perennial, so it grows best over a period of time (3 years and greater).

Globe thistle is known for growing to a height of approximately 3.90 feet (that's 1.20 metres in metric) with a erect habit. This plant tends to bloom in late summer, followed by first harvests in late summer.

If you would like to attract bees to your garden, consider growing this plant.

Globe thistle is great for inexperienced gardeners and those that like low maintainance gardens.
