Pruning

Water
Globe thistle should be watered deeply but infrequently, as the plant is drought tolerant. The top inch of soil should be allowed to dry out before watering again. Typically, 1 gallon of water per plant every 7 to 10 days during the active growing season should suffice, but this can vary depending on climate conditions. Be sure to reduce the watering frequency as the plant goes dormant in the winter. Overwatering can lead to root rot, so it's essential to ensure good drainage and to avoid letting the plant sit in saturated soil.
Light
Globe thistle thrives in full sun conditions, where it can receive at least 6 hours of direct sunlight daily. The best spot for this plant is in an area that provides unobstructed sunlight for most of the day, as this will promote vigorous growth and optimal flowering. Partial shade is also tolerated, but the plant may not bloom as prolifically.
Temperature
The ideal temperature range for globe thistle is between 60 to 75 degrees Fahrenheit. It can tolerate temperatures down to about 30 degrees Fahrenheit but should be protected from prolonged freezes. Similarly, globe thistle can survive temporary spikes above 75 degrees Fahrenheit, but consistent high temperatures may affect its growth.
Pruning
Globe thistle should be pruned to remove spent flower heads and to encourage additional blooming. Pruning can be done in late summer or early fall after the flowers have faded. Deadheading, or cutting back the entire plant to its basal leaves, can be performed annually. The best time for pruning is after flowering, to prevent self-seeding if desired, and to tidy up the plant.
Cleaning
As needed
Soil
Globe thistle 'Arctic Glow' thrives in well-draining soil with a pH of 6.0 to 7.5. A mix composed of garden soil, compost, and sand in equal parts provides the ideal texture and fertility for robust growth.
Repotting
Globe thistle 'Arctic Glow' typically requires repotting every 2 to 3 years to refresh the soil and accommodate root growth or when it becomes root-bound.
Humidity & Misting
Globe thistle 'Arctic Glow' is tolerant of dry to moderate humidity levels and does not require high humidity to thrive, making it suitable for typical outdoor conditions.
Suitable locations
- Indoor
  Place globe thistle in bright light and water when soil feels dry.
- Outdoor
  Plant in full sun, well-draining soil, and water regularly.
- Hardiness zone
  3-8 USDA
Life cycle
Echinops sphaerocephalus 'Arctic Glow', also known as Globe Thistle, starts its life cycle when the seed germinates, typically in spring, given moist soil and cool temperatures. The seedling stage follows, with young plants developing a rosette of leaves at the soil surface. As it enters the vegetative stage, the rosette grows larger and the plant begins to form a sturdy stem. During the flowering stage in late summer, 'Arctic Glow' produces striking globular, white flower heads on tall stems, which are highly attractive to pollinators. After flowering, the plant sets seed, which can be dispersed by wind, allowing for the colonization of new areas. In winter, the plant dies back to the ground, with the roots remaining dormant until the next growing season begins.
Propogation
- Propogation time
  Late summer
- Echinops sphaerocephalus 'Arctic Glow', commonly known as Globe Thistle, is often propagated by seed or division. The most popular method is division, which should be done in early spring or late fall. To propagate by division, carefully dig up the parent plant, making sure to keep a good amount of soil around the roots. Using a sharp knife or spade, divide the root ball into smaller sections, each with several shoots and a healthy portion of roots. Replant the divisions at the same depth they were growing previously, spacing them about 18 to 24 inches (45 to 60 centimeters) apart to accommodate future growth. Water the new plantings thoroughly to help establish their roots. It is crucial to maintain consistent moisture without overwatering during the first growing season to ensure successful establishment.
