1.       Open-pollinated species, with the exception of a very few, may not come true from seed. Cultivars, with the exception of a few perennials do not come true. Plants from these seeds should be labelled as being “ex” that species or cultivar.

2.      The 2012 Seed List will be posted on the Internet with insertion of images and links to help in your decision-making.


           Follow the links for ARHS Seed Exchange.

           A link to the list will be inserted on the Atlantic Rhodo site.

3.       Also see the ARHS website for an article on growing rhododendrons from seed.

4.       When sowing rhododendrons on peat we recommend you sterilize it first. Microwave it for 15 minutes or pour boiling water through it several times. Allow to cool.

5.       We would like to thank the seed donors for their time and effort making crosses, collecting and cleaning seeds.

          We highly encourage members to attempt their own hybridization of rhododendrons.

          Seed of uncommon trees, shrubs and perennials is always most welcome.
