Growing Primulas

16 years ago

Hi there,

I ordered three primulas from T&M--Japonica miller's crimson, drumstick mixed primula denticulata, and primula capitata noverna deep blue.

From a thread started by 1morehosta last spring, I read that primulas can be slow to germinate for some and certain T&M seeds seem to be finicky.

How did primulas winter sown last year perform or survive?

From what I have read, primulas are hardy perennials, so they would seem good candidates for winter sowing in zone 5.

What are your tips for successfully germinating primulas?

Thanks!

Norabelle

    Hi Norabelle-

    I tried 2 types of primulas last year-- one was a primula japonica that I received from another gardenwebber and one was primula vulgaris from T&M.

    For the p. vulgaris, I followed the directions on the back of the seed packet; the p. japonica, I WSed (but not until the end of March... because that is when I received them). The p. vulgaris did not germinate, but the p. japonica (that I winter sowed) germinated very well. I had way more plants than I expected and by the end of summer, some of them were 6-8" tall...I didn't get them planted out right away, so some of them stayed smallish.

    I am going to try to start the p. vulgaris again this year, but this time I will winter sow them.

    I sowed them all last year,none of them germinated.
    I am sure i did something wrong, maybe started them to soon.
    As i did do this with a lot of seeds last year, it was my second season,and i made a lot of mistakes,
    Good luck with yours, it is a really pretty plant, and i did want them so badley,still learnig a lot.
    I think there were others that had no problem a t all with them,

    In 2008, I wintersowed Primula japonica 'Miller's Crimson' on 1/16 & had germination on 4/7, primula japonica purple on 2/3 & had germination on 3/25, primula macrophylla violet-lilac on 2/3, but had no germination. The seeds were from NARGS and a local garden.

    In 2009, I wintersowed primula denticulate 'blue selection' and primula capitata ssp. Mooreana from Hardyplants.com on 4/8 & had germination for both on 5/8. I had more than enough of each and am planning on trying to WS more primulas this year.

    Good luck!

    Thank you for all the responses. I am feeling more inspired and excited about my primula seeds.

    cAROL, thank you for your help and candor. I wish us both good primula mojo this year. :)

    I am just going to do my usual WS perennial routine with the primulas. Otherwise, I am going to psych myself out with all the additional steps, coverings, and pots I could use to germinate these wonderful flowers.

    I am always grateful for the shared wisdom, enthusiasm, and experience of this forum!

    cheers,

    I did primula vialli last year. I winter sowed it early probably Jan something. It did really well and I have tons of little plants out there now. I can't wait to see how they do over this winter and if they bloom for me come spring. :)

    I started 'You and me blue' early this last February and by Thanksgiving they still hadn't reached 2 inches other than that they looked healthy up until the snow started to fall. Hope they're big enough to make it through the winter, they might have been safer if I had just left them in the jug.
