WaterGlobe thistle should be watered deeply but infrequently, as it is drought tolerant once established. During the first growing season, to help the plant develop a deep root system, water once a week with about 1 to 1.5 gallons per plant, depending on soil type and climate. After establishment, reduce watering but make sure the soil does not dry out completely. Cut back on watering in the fall to prepare the plant for dormancy. Pay particular attention during extended periods of drought or extreme heat, and water the plant more frequently.
LightGlobe thistle thrives in full sun conditions, where it can receive at least 6 to 8 hours of direct sunlight each day. The best spot for planting globe thistle is an area that has clear exposure to the sun without any shade, as too much shade can lead to poor flowering and a leggy plant. Avoid locations where buildings or other plants cast shadows for the majority of the day.
TemperatureGlobe thistle can tolerate a range of temperatures but grows best in conditions between 60 and 75 degrees Fahrenheit. It can withstand minimum temperatures down to about -20 degrees Fahrenheit, making it suitable for cooler climates. However, it should be protected from extreme winter conditions where temperatures consistently fall below this range.
PruningPruning globe thistle is important to maintain its shape, encourage new growth, and improve its flowering. Deadhead spent blooms to encourage more flowers. Cut back the plant to the ground in late fall or early winter after the foliage and flowers have faded. Perform a thorough pruning once a year during this dormant period.

Life cycleEchinops bannaticus, commonly known as blue globe thistle, begins its life as a seed, which when sown, germinates in a variety of conditions, although it prefers well-drained soil. After germination, the seedling develops into a rosette of spiky, gray-green leaves, staying in this vegetative state through its first year. In its second year, the globe thistle sends up sturdy, branching stems that can reach up to 3-4 feet tall, with the distinctive spherical, blue or violet flower heads forming at the tips. These blooms attract a variety of pollinators throughout the summer months before eventually producing seeds by late summer or early fall. Following seed set, the plant may die back, completing its lifecycle, but it can also behave as a perennial, regrowing from the base in subsequent seasons. In the latter case, the cycle of growth, flowering, and seed production repeats annually.
PropogationPropogation time
Spring-Early Summer
Propogation: The Globe Thistle, Echinops bannaticus, is most commonly propagated by seed. The ideal time for sowing Globe Thistle seeds is late winter to early spring, just after the last frost when temperatures start to warm. One can start the seeds indoors in seed trays or sow them directly outside in a prepared bed. If starting them indoors, the seeds should be lightly covered with soil and kept moist until germination, which usually takes about 2 to 4 weeks. When seedlings are large enough to handle, typically when they have a couple sets of true leaves, they can be transplanted to their final positions in the garden, spacing them about 18 inches (approximately 45 centimeters) apart to allow ample room for growth.
