FOOTNOTES

†1. R. tomentosum, a species from Ledum subsection, cw from Turku Archipelago, Finland.

†2. R. hypoleucum, Ledum subsection, plant from ARS 87/2004

†3. ‘Helsinki University’ is a super hardy Finnish hybrid with pink flowers.

†4. R. fortunei ‘Best Form’, aka ‘German Form’, found from Hobbie Rhododendronpark.

†5. ‘Goldprinz’ syn. ‘Goldschatz’, good yellow, (‘Festivo’ x ‘Alice Street’), cross by H. Hachmann.

†6. ‘Nancy Steele’, formerly BPT#80-5, yellow

†7. ‘Mikkeli’ aka ‘St. Michel’ is a hardy Finnish hybrid.

†8. ‘Böhmen’ is pretty hardy and probably a form of dichroanthum ssp. scyphocalyx.

Selfing should give variation as the orange flowered ‘Böhmen’ is a suspected hybrid.

†9. ‘Cherry Kiss’, one of the best hardy reds from Hachmann

†10. ‘Goldsworth Orange’, dichroanthum x fortunei ssp. discolor, cross by W.C. Slocock.

†11. ‘Barbara Cook’ = ‘Mary Belle’ x ‘Goldsworth Yellow’

†12. ARS97#671, ’Cat’s Pajamas’ (Delp) x {Janet Blair x [( wardii x hemsleyanum) x Autumn Gold] #1/95}

†13. (R. tomentosum x R. groenlandicum), a very floriferous cross between two tetraploid Ledum species.

†14. R. tomentosum x R. diversipilosum ‘Milky Way’, a vigorously growing and well flowering Ledum cross.

†15. Cornus seed has been stratified. Store in fridge in plastic packet as received until

March/April then sow in warm soil.

†16. Diphylleia cymosa, seed has been stratified. Store in fridge in plastic packet as received until March/April then sow in warm soil.

†17. Hellebore seed may take 6-18 months (or more) to germinate; however, if you start with fresh seed and sow it soon after harvest, then your chances of achieving high germination percentages are quite good. For example, sowing fresh seed in damp media at room temperature for eight weeks followed by a cool period in the refrigerator for another eight weeks or so will yield good results.

We shall try to ship “treated” seed.

†18. Hippophae rhamnoides, seed has been stratified. Store in fridge in plastic packet as received until March/April then sow in warm soil.

†19. Lilium seeds may require a warm/ moist period followed by a cold period if there is no germination. Plant cold treated pots outside in spring.

†20. Magnolia seed has been stratified. Store in fridge in plastic packet as received until March/April then sow in warm soil.

†21. Seed has been stratified. Store in fridge in plastic packet as received until March/April then sow in warm soil.

†22. Viburnum betulifolium, seed has been stratified. Store in fridge in plastic packet as received until March/April then sow in warm soil.

†23. cp = Controlled Pollination, where stigmas have been protected before and after pollination.

NOTES

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.

http://www.willowgarden.net

Follow the links for ARHS Seed Exchange.

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

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.
