It is hardy to between USDA Zone 4a and 9b.
Between  (−34.4 °C (−30 °F) to −3.8 °C (25 °F)).

It is also hardy to WHZ 4–9, and within Europe H2.
The leaves often survive the winter.

Due to this hardiness it is assumed fairly 'easy' to grow.

Although native to saline soils, it is tolerant of many garden soils.

It prefers positions in full sun or partial shade.

Sometimes slugs can be a pest, and can nibble on the young shoots.

It sometimes can take several years to start flowering again after being moved.

But once it is 'settled', it can develop into a large round clump.

It is very widely grown and cultivated in gardens, parks and plazas.

It also could be grown within an orchard and is also good for use within a cutting garden.
