These species were identified by participants at Kew's 'Difficult' Seeds Project workshops as showing poor germination during initial testing and/or during re-tests after storage. Low germination may be due to inherent issues such as seed storage behaviour, dormancy or seed longevity, or to handling and storage difficulties. Follow the links for information about germination requirements and storage behaviour that can help overcome these difficulties.
