Cynara cardunculus

Cardoon features showy purple pincushion flowers rising above the foliage from late spring to early summer. Its attractive spiny ferny leaves remain grayish green in colour throughout the season.

Cardoon will grow to be about 5 feet tall at maturity, with a spread of 4 feet. It grows at a medium rate, and under ideal conditions can be expected to live for approximately 10 years. As an herbaceous perennial, this plant will usually die back to the crown each winter, and will regrow from the base each spring. Be careful not to disturb the crown in late winter when it may not be readily seen!

This plant should only be grown in full sunlight. It does best in average to evenly moist conditions, but will not tolerate standing water. It is not particular as to soil type or pH. It is highly tolerant of urban pollution and will even thrive in inner city environments, and will benefit from being planted in a relatively sheltered location. This species is not originally from North America.
