Full sun keeps the purple deepest; in shade it fades toward green. It's not a fit for wet, poorly drained ground, and the thorny stems make it a poor pick right beside play areas or walkways. Note: Minnesota is phasing out Japanese barberry sales in the coming years, so check current availability rules if you're planning a large future planting.
