Does anyone know how to plant a rhizome for an anemone honorine jobert?

I've got a few rhizomes for an Anemone 'Honorine Jobert' from the garden centre and there are no planting instructions. I've planted a load of wood anemones today but these look completely different, almost like a bare root plant. I'm not even sure if it's best to plant them now or in the spring as they are Autumn flowering.

Any advice would be much appreciated, I can't find anything online! 

Many thanks, 

Julie

    If they look dry, give them a soak and plant. If you have some protection such as a cold frame, I would put them in there (in a pot)for the winter, and then in their final position in spring. If you dont, then get them in final position. Leaving a root to dry out even further will probably mean it will take a number of years to get going.

    Japanese anemones are totally different from anemone blanda and de caen, which come from corms. What you have there is a rootstock for a perennial plant.

    It's not a mess, it's a nature reserve.
  • Thanks for the advice. Ah so it's a root stock, I assume I want the top above the soil? Sorry for asking such a stupid question.

    You need to plant them now, they won't last til spring if you dont. 

    Do you think these are newly packaged up or left over from earlier in the season? In the garden these are flowering now, getting owards the end maybe. I wouldn't expect to find them for sale as just a root now.

  • I've had them for a few months image thinking that they needed to be planted in Autumn but they are Autumn flowering so should of been planted in Spring I think. I'll soak them and put them in pots. I could try overwintering them in the greenhouse. I don't have much luck with Japanese Anemone's as much as love them, I lost a few that I planted from pots... I so wanted some white flowers for a border in shade.

    I don't have much luck in getting them started either, though one clump has established. I tried Honorine and an un-named white, both dead. I've just been given another white and hope it will survive. Maybe I should pot it up and nurture it a bit. It's a couple of bare roots and only been in the ground a day or tow.

  • These didn't cost much unlike the established ones I planted from pots. About half of those didn't survive. I've decided they are not the easiest of plants to grow and I'm not buying any more.

    It's something I've found in the past. Some very invasive plants are very hard to get going.  chinese lanterns and lily of the valley, are another 2.

  • They don't like being dry or darker shade, very temperamental.

  • i have soaked them and planted them,but I have a feeling I have planted them up side down.The nobble bits up ,I wonder.image

    I would expect the nobble at the top, roots taper away to nothing as a rule
