Plant Availability

Schedule of Plant Availability

Most plant material is seasonally available. To expedite
your order for dormant material, please make sure that your request is received
by the deadlines listed below for each genus. Spring bud break in Corvallis
usually occurs in early to mid-February, which limits the distribution of
dormant cuttings and scionwood. Pollen and other propagules may be available by specific request. Please
