We have started a "Blog" aimed at Rhododendron/Azalea Seed growers who have participated in the annual Seed Exchanges over the last several years. It is entitled "Atlantic Rhodo Seed Growers". Check out the link. Participants are welcome. Just email for directions if you have questions re access.

Here are some useful "homework" links:









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 not be labelled as being that species or cultivar. Be sure that you label the plants as being ‘OP’ in the case of species and ‘ex’ in the case of cultivars.

2.      The 2007 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.       See the RSCAR Members’ Handbook for an article on growing rhododendrons from seed. An article can also be found on our website.

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 would also like our membership to take note of the types of seeds donated this year. We highly encourage members to attempt their own hybridization of rhododendrons. Seed of uncommon trees, shrubs and perennials is always most welcome.
