This thread is the official thread of the OPPF (me).
My Indian Paintbrush plants are growing and flowers are out on both the sulphurea and miniata. These are not supposed to flower till the second year so this is a good sign that they are doing well. Pictures to follow. The host and parasite are both coming back for their second year. A bit of a poor showing this year probably because of the super heat wave.
My West Australian Christmas tree seedlings are growing in a pot of Bermuda grass (really an Australian grass species). Getting bigger.
The Viscum minimum infecting a Euphorbia horrida cutting is flowering. I'm waiting for berries so I can infest my E. polygonum "snowflake." The viscum seems dormant now.
Still waiting for Orobanche hederae in my English Ivy pot. Maybe try a dormancy in the garage this winter. English Ivy is BORING!
Waiting for correct host seeds (Berkheya radula) for Harveya speciosa.
Euphorbia flanagani as host for Hydnora africana seeds.
Chilean hosts seedlings growing for Tristerix verticellatus. The seeds came but damaged with no germination. Better luck next year.
I couldn't get Harveya speciosa to grow. I suspected the wrong host was the problem. All I could find on the web was a reference to a 1932 South African journal article. Only two places anywhere that sold copies. One was from the publisher for a crazy amount of money for a little pamphlet. Finally found a copy for 9 pounds Sterling from England. Just got my copy. Berkheya radula is the preferred host and both seeds are available at Silverhill Seeds. Might buy some dew seeds too. Per ardua ad astra.
Indian Paintbrushes came back but not too strong. I think the weather was too hot. WA Christmas tree is growing slowly. Viscum minimum seems dormant although the host is growing. It's really hard to get hosts growing and harder to get parasite seeds. Still plugging along.
Parasitic plants are the new frontier for horticulture as far as I can see. I'm talking about interesting plants not dumb ones like dodder or super invasive weeds like Striga.
My Euphorbia horrida got mealy bugs from a Lithops I bought at Sheridan Nurseries (Should have done a better check?). Unfortunately the mealies only attacked the Viscum minimum! I treated it with 99% Isopropranol (even the roots after I cleaned the soil off). I've replanted it. The Viscum is inside so hopefully it should pop out again. Treated the lithops the same way.
After a major set-back (mealy bugs & toxic treatments) my Viscum minimum is coming back! Now that I know which flowers are male and female, I'm hoping to get some berries sometime. My Indian paintbrush came back but is really poky, maybe they'll flower this year. West Australian Christmas trees died and I'm trying to germinate some more. Various hosts growing for South African, Chilean and Australian loranths and Orobanchaceae (or not-Harveya berkheya is impossible to germinate).
