Eryngium 'alpinum' - ?where to keep if planted now
| | |
Posted by rcharles Vancouver 7b (My Page) on Sun, Oct 11, 09 at 11:04
Hello,
I was given some Eryngium 'alpinum' seeds. I had read somewhere that sowing them fresh was better (with alpinum).
Has anyone had experience with these or do you have information on were they should be stored if I do sow some now, (outside or in coldframe)? |

| Either leaving the pots outdoors or placing in a cold frame would be fine. Sow now, barely covered or covered with some grit. They should experience some warmer (relatively speaking) Fall temps, followed by a moist chill, and should germinate for you in 7b late winter or early spring while temps are still cool. |

Hello Morz8,
I had planted some of the fresh Eryngium seed up before I had posted Oct 11th and appreciated getting your information. I went into the greenhouse (unheated) today
and there are very large number of seedling merging through the grit. I do not heat the greenhouse through the winter. Do you think that I need to have them in a warmer situation through the winter? I believe that they are hardy to about Zone 4 or 5.
Not sure if seedlings will tolerate these temps.?
If you get this message, could you give me your thoughts.
Thank You

| I think if we have a normal winter they should be fine in your unheated greenhouse. They should be hardy to at least Z5 but no, that doesn't necessarily apply to newly germinated seedlings with scanty root systems....but it's an almost balmy 57 here today and I don't see anything frigid in the immediate forecast. Sometimes seeds surprise us:) I haven't had that happen with eryngium, but I have a pot of newly germinated genista tinctoria I sowed for my neighbor I'll have to hold over winter. The databases suggested very hard seed coat, sulfuric acid or boiling water soak followed by an extended stratification. I did the boiling water soak and had seedlings in three weeks. Depending on the number of true leaves present, if we were to have something like last Decembers storm forecast, I might be tempted to give them further temporary protection for the duration of the storm...like inside a styrofoam camping cooler. |

Thank You Morz8,
Going to do as you suggest. Keep an eye on the weather.
Looks like there are going to be quite a number if they survive. Quite excited. I bought some seeds last year from a supplier (Ms. Whilmot's Ghost and alpinum) only ended up with one of each by the time they where ready to plant out. Put the seed through the scarification requirements, with very poor germination.
I have found with so many of the seeds that I have started that if you can get fresh seed and plant it right away the germination is remarkably better.
The Cyclamen, Erythronium,Helleborus,trillium,dodacatheon,
and many more that I have tried over the years all do better if you have the seed.
Don't mean to ramble, but the trying to start different plants from seed and/or cuttings has always interested me.
I managed to get some Romneya Coulteri started, only a couple from a packet of seeds.
Again, thank you for your info. |
