Thanks for input.  I will skip yuzu, though I am still curious about sudachi

Anybody have experience with these varieties?  Their reported unique flavor always sounded interesting to me but I don't have much use for juice so I'm not sure what I would do with the seedy fruit.  I looked online for the fresh fruit for delivery but can't find any.  There is bottled 100% juice available but not sure if its good representation of fresh. 

I'm running out of space right now but I still have the itch to try new varieties. 

Good to know.   I will have to take some temperature measurements aroud the floor to see where is best.

Most of my citrus trees are blooming now, in what should be their last winter in the old greenhouse.  Kumquats are still dormant as usual, but everything else is pushing new growth, even the pummelo I got a year or more ago that until now hadn't put out *any* new growth.

I forget what this one is, perhaps the Flame grapefruit


Chandler pummelo



And a mango tree I bought last summer looks like it is about to break buds.

If you've ever had "orange drink" that's what the one I ate tasted like.  I'd certainly eat a few more before I make up my mind but I'm not expecting it to be a favorite.  My interest started in this when someone mentioned they heard it tastes like mango, which I love.  I don't detect any mango taste though

The centennial in the picture looks nicer than the ones on my current crop.  Hoping it improves next year.   My first crop of Meiwa was very poor, but subsequent ones have been great.

Did the leaves drop off first?  Or did the branches die with them still attached?

When I've had trees die of wet roots the leaves yellowed and dropped first.   When I've had trees die of thirst the leaves dried out in place and stayed attached

I'm looking forward to trying these!

Though these names are getting way too generic.  I just tried a new apple variety... "Sweet Tango" (it was very good btw). 

I've accumulated pretty much every kumquat and hybrid that I can find.  Here's my impressions so far...

Nagami (Nordmann Seedless) - excellent taste.  Sometimes a slight soapy taste if not 100% ripe, somewhat astringent also
Nagami - excellent taste but has seeds.  More sour than nordmann because its fatter and so has more juice.  Sometimes a slight soapy taste if not 100% ripe,   somewhat astringent also
Marumi - excellent taste, some seeds
Meiwa - excellent taste, some seeds.  Less sour than other kumquats because it has more flesh than juice
Fukushu/Changshau - my personal favorite.  Initially mine were about the same size as marumi/meiwa and nearly seedless.  More recent crops have been much larger, about the size of a golf ball, and with significantly more seeds.  The smaller ones were better in my opinion.  I'm hoping that limiting pollination or using giberellic acid would help reduce seed count and also fruit size.
Hong Kong - not really edible because of tiny fruit size, no juice, all seeds.  I did eat a bit of the flesh on one and it is somewhat sweet but this is a pure oranamental & breeding parent
Indio Mandarinquat -  poor taste for two years in a row.  Skin is thin and dry, not enough sweetness to offset sour juice.  Off taste similar to Rangpur but less spicy.
Centennial Variegated - poor taste for me on my first crop.  Similar to Indio Mandarinquat.  Thin is skin and dry, not enough sweetness to offset sour juice.  Off taste similar to Rangpur but less spicy.    This variety supposedly has a reputation for good taste so I'm hoping it will improve next year but I don't expect the character to change.
Nippon Orangequat - decent but somewhat bland taste.  Skin is thick and bland, whole fruit is a bit sloppy as the flesh is soft and juicy.  Not worthwhile in my opinion because skin is not sweet like more common kumquats, size is as large as a navel orange, taste inferior to navel orange, and has seeds.  You'd be better off with another kumquat or a sweet orange.
"Excalibur" Red Lime - UCR mentions likely Kumquat/Rangpur hybrid.  This one was a surprise to me.   I couldn't locate one forever and ended up trading with Lorewren on this forum who lives nearby to me.  I've been eating the first crop over the past four months and they keep getting better the longer they hang on the tree.  They are now dark orange and about the size of a Clementine.  They taste quite good, like what I was expecting from Nippon Orangequat.  The skin is sweet and relatively thick.  When first turning orange 3mo ago they were sour but now they are sweeter and I eat them out of hand.  There is a bit of the Rangpur taste but not strong.  Seedy, though.

Lakeland Limequat - typical lime flavor.  Thin rind that was rather dry and not at all sweet.  Few seeds.   I wouldn't recommend over a Bearss lime unless you need the cold hardiness. 
Sunquat -  bright yellow like a meyer lemon, and tasted similar.  Thin skin, not sweet but not too dry.  Much sweeter than a true lemon.  Again, if you need a lemon I'd stick with a real one, but the Sunquat fruit is very attractive looking as it's perfectly round and bright yellow.   I'm thinking I will keep this as an ornamental.    (RyanL - you called it)

It seems very easy to end up with far too many lemons and limes.  Also good to think about getting multiple varieties or ones known to hold on the tree well, as the sweet citrus tend to all ripen at the same time so if you don't use the whole crop quickly they go bad. 

Right now I have dozen kumquat trees with fruit I can just barely eat it all.  Once they get larger I'll have to start giving some away.

Not bad at all! 

I've always refrigerated mine.  I think it tastes better cold.
