Since June 2009 I live on the far western tip of french Brittany, about 1km from the ocean. The ocean's influence makes for mild winters (a very exceptional -3°C/27°F at night is the minimum we've had so far and temperatures always climb back above freezing point during the day), as well as mild summers (25°C/77° can be considered "hot"). We've had snow for 2/3 days this winter and the previous one. The only thing that can be quite extreme here are the november winds. I guess the problem here isn't so much the minimum winter temperatures as it is the limited summer heat and thus the ability of certain citrus trees to bear decent fruit. Last summer I've planted a Poncirus trifoliata wich seems to be doing well so far (no fruit yet but I suppose it won't be much of a problem), but I'm wondering what else could grow fruit to maturity with success. I have a satsuma and meyer lemon in containers (both grafted on Poncirus), a few kumquat seedlings (all inside for the winter) and would like to get a yuzu. Do any of these have low heat requirements to grow their fruit to maturity? Any other citrus types? Thanks for any input.

If your zone 9B with not much heat in summer satsumas should do well. They do not require much heat for good fruit quality. Meyer lemons may do well also.

I think kumquats should do well...and calamondins too. Good luck!

'Trovita' orange gives good tasting fruit in low heat conditions.
Whether it would survive your wind and wet, I don't know.

I agree with the Trovita orange suggestion. This past summer was the coldest and windiest summer I can remember where I live. The satsumas I harvested were bland and tasted like water. I expected the Trovita oranges I grew to be very poor too with little sweetness. When I harvested them they were excellent. They were very juicy with good texture and well balanced sweetness and acidity.

I would suggest New Zealand grapefruit ( Poorman orange), it has less heat requirements than most of citruses.

Thanks for all contributions so far. Does anyone know where I could find the Trovita and Poorman Orange? They don't seem to have them at Bachès.

Yes, he is one of us now.
Surely a much better place to ask for budwoods because it is legal.

You will find newzealand grapefruit easily but I have never seen Trovita in Europe. Ask on the French forum...

It is nice to see that we are more an more to be on both forum.

Thanks Ilya, I just saw your posts on the french forum.
I see you also bought a Yuzu at St Georges, do you remember how much both trees cost you?

Sylvain, I didn't know budwood was illegal in the US. Une histoire de brevets et de fric?

I believe Sylvain meant that it is illegal to take budwood or trees from the U.S. to Europe or from Europe to the U.S. to prevent the spread of disease. Budwood is not illegal in the U.S.
