Seed collections are the most compact and cost-effective method of storing a wide range of plants.
Did you know that we store over 100,000,000 seeds in our vault?
One seed packet of Juncus bufonius, a small toad rush that grows in moist and muddy places, holds over 2.3 million seeds. Several of our orchid collections, including Cymbidium suave, an epiphytic snake orchid, may hold as many as 10 million seeds! Some plants are so rare that we only have a few seeds of those species.

However, not all species are suitable for seedbanking, including those that do not produce seeds or those that produce seed that cannot be dried. Tissue culture is an alternative to seedbanking for these species but it is more time-consuming and expensive and requires specialist laboratory facilities.
