They need potting on fast and can be planted out in a rich humid bed by mid-July. " Click here for cultural info  Best sown as fresh as possible.more info

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

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

4. 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.
