The Tropical Fruit Forum

That's really cool. I might have to visit the nursery on Sauvie island sometime. I wasn't aware of too many other people (or any at the time actually) trying to grow hardy citrus in the Pac NW when I started trying it myself back in '94. It's good to find out there were others around that time period too. There was a nursery I bought my first Morton Citrange from back in 1994 located in Molalla, OR. which was called "Northwoods Nursery" which I think One Green World is on offshoot of. There were mail order nurseries including one in Oregon called "Oregon Exotics" (no longer around) that had some cold hardy citrus offerings (but some felt they exaggerated the hardiness and/or edibility of the varieties they sold back then). Also, before the big onset of the internet, I did all of my cold hardy citrus research from Libraries. That's where I first found out about Citranges and PT (1993). After I started dabbling with the internet, I started the "Hardy Palm & Subtropical Board" (1997) and was able to correspond with others easier (much better than snail mail) and could collaborate on the subject better, as we do here. So it was great to find the recent Oregonian article and also find that there were some others who have been at this for a long time as well (Pac NW growers).

My interest actually started after moving up from Southern California in the '90s and having some banter with my ex father-in-law about the advantages of living up here. We were bantering again one time and he said to me "How many orange trees do you have growing in your yard?" and I thought, I wonder if there are any cold hardy orange trees? I started doing research and the rest is history as I caught the cold hardy citrus bug.

Anyway, I might give that nursery on Sauvie a visit. Sounds interesting. Thanks for the info.

That is a pretty cool hybrid. I think growing out a few seedlings might produce some interesting results. I planted a few seeds from a store bought Meyer Lemon many years ago and now have a Citremon tree (tentatively named the "Picone" Citremon, it has trifoliate leaves, so I know there is PT in the mix) that has proved very hardy to frost and the cold damp winter conditions we have in the Pacific NW. It hasn't fruited yet, but am hopeful the fruit will be an edible quality (Meyer lemon is a hybrid to begin with, so my Citremon will be a nice complex hybrid). I would be curious to find out what the results are from any seeds you germinate from that fruit you have. Again cool fruit.

Nice Kabosu write up Jim. The fruit you gave me was pretty good, nice mellow lemon flavor with no off flavors.

Awesome about the marmalade. Sounds great.

It also seems to be a good candidate for long term in our Pac NW climate. I look forward to hearing how it continues to do for you over the years and might give it a shot in my yard too.

Take a look at the pics in this forum on the old Citrus Grower's forum of a guy with a Morton citrange. One Green World used to sell Morton a long time ago when they were Northwoods still (I bought one back in '94, I believe. Never got fruit from it unfortunately before I had to leave it when I moved. It was in a pot and I was living in Albuquerque, NM at the time back in '97). I think this looks a lot like what you have Jim:

What do you think?

Very cool variety. Would love to be able to find a source of this located within the US.

Looks like you're dealing with leaf chlorosis (yellowing), very common problem with subtropicals grown in the Pac NW due to the cold dampness a lot of the year. I don't think cold hardiness of a plant has as much to do with it, as does a citrus plant's ability to tolerate cold "wet feet" (which none like, but some tolerate better than others). You will see this issue on Trachy palms (as well as other palm species) from time time in our climate too. I have found over the years that cold dampness is much more of an issue than outright cold hardiness where we live. That's why finding specimens that can tolerate the cold dampness (including soil temps/moisture) in conjunction with cold hardiness is the real key to success with cold hardy citrus here. I would try possibly amending your soil with some sand for drainage and so it can dry out faster. I think container plants are much more susceptible to this issue unfortunately (I have grown many many over the years).
