Ranunculus

[Oron Peri]

Here's an interesting Ranunculus hybrid. Any guesses?

Lesley,
it looks to me as a cross [not hybrid] between the red and yellow forms of R. asiaticus but if you have more details they might be of a help, leaves might do it too...

[Lesley Cox]

Hi Oran.

I promise you, it IS a hybrid, between R. cortusaefolius (seed) and a red garden form of
R. asiaticus.. Here's the plant it came from.





R. cortusaefolius seems to take just about anything, including our gorgeous R. lyallii, the Mt Cook buttercup, giving richly cream-coloured seedlings. I'm even trying it with pollen from R. godleyanus. If it has taken, God may forgive me but the Conservation Dept won't. The plant pictured here is sterile.

Oh Lesley,
Isn't R. godleyanus beautiful enough for you?   

[Miriam]

Ranunculus asiaticus, very common and well-known plant in Israel because of its attractive large red flowers. There are also forms in yellow and orange.

[Lesley Cox]

GORGEOUS!!!

Ranunculus creticus, under glass & safe from slugs but with a touch of botrytis unfortunately.

[Lesley Cox]

But still lovely Ashley. Is it botanically close to R. cortusaefolius?

But still lovely Ashley. Is it botanically close to R. cortusaefolius?

Yes, it is (lovely and allied). Both are in section Ranunculastrum (together with R. asiaticus)

That would explain why hybrids can be made between RR. cortusaefolius and asiaticus. But how about R. lyalii. I don't imagine that's in the same section but it will hybridize with R. cortusaefolius.

Lesley,
This strange hybridisation was the reason for me to look for the section of both.
The NZ Ranunculus belong to sections Chrysanthe and Epirotes.
It isn't mentioned to which Ranunculus lyalli belongs.

There is a comprehensive review of the Genus Ranunculus in The Rock Garden beginning in Vol. 77 (7 parts) by Alastair McKelvie.

Dew to the high temperatures R. asiaticus is already in flower in some areas.
Here is the common red form and the much less common Orange form.

Miriam, have you noticed your flower is a double form...[10 petals]

[Oron Peri]

Another species a bit early this year

Ranunculus millefolius ssp hierusolymitanus

[Lvandelft]

What a beautiful subspecies Oron, really one to try cultivating!
R. millefoliatus are normally easy to propagate.

[Gerdk]

Luit,
Ranunculus millefoliatus is a buttercup which is more than easy to propagate. It took me 3 years to get rid of this weed. Although a nice plant it spreads around awfully by means of seeds and pieces of the rhizome.
R. millefolius seems to be somewhat more civilized.

Thanks Gerd, I'll have a look. My lastest issue of The Rock Garden is Vol 31, No 122. Do you mean No 77? (Yes, you do.
