This is a great source of citrus information. Pleased I found it.
My citrus endeavors so far consist of,
In the ground..
1 Murcott, 1 Encore Mandarin, 1 Miho Mandarin, 1 Silverhill Mandarin, 1 Clementine Mandarin, 1 Miyagawa Mandarin, 1 Bay Sweetie Tangor, 1 Bay Sunset Tangor, 1 Seminole Tangelo, 1 Calamondin, 1 Cipo Orange, 1 Meyer Lemon, 2 Variegated Lemon, 1 Hayward Late Valencia orange, 1 Tavarres (?) Limequat, Persian lime , Lemonade...
Ready to plant when it's warmer..
1 miyagawa Mandarin, 1 Kiyomi Tangor, 1 Variegated lemon, 1 tarroco orange, 1 Nagami Kumquat.
Ordered from Garden Centre.
2 Meiwa Kumquat, 1 Vainglia Orange.

The only well advanced tree is the Seminole Tangelo which is very popular here in New Zealand. Can't eat Grapefruit due to medication so won't plant any.
Getting a wide variety is hard in New Zealand where plant importation of new varieties is severely monitored and a very expensive process has to be followed for any commercial nurserymen to import so they don't bother.
My question (sorry to take so long to get around to it)... A local gardencentre has Kusiae lime trees. I need one more tree...
With my variety of trees would you plant one?
There is little info on the net about Kusiae. Is it worth garden room?

Found this finally..
Lemandarin or the Mandarin lemon belongs to a group of several closely related types of citrus trees. All are crosses of lemon and mandarin. They resemble the mandarin in appearance but taste more like limes. The mandarin lemon has three well-known varieties Rangpur, Otaheite and Kusaie.

Would still like to know if it is worth garden space?

Hi Glenn, I've tasted the Otaheite from a supermarket. It wasn't nice but not terrible either. Like the description says it looked like a yellow coloured mandarin and tasted like one too. I'm guessing it would taste much better fresh from the tree, store bought fruit always tastes bland or stale to me. Unfortunately none of the ones I bought had any seeds, but from an eating standpoint that's convenient lol.

Trouble is the Otaheite is, according to my newly found web bits and pieces, quite mild compared to the Kusaie.
I don't know how sour the kusaie is (I love ripe calamondins eaten off the tree) however I hate to go past something that may never return to my locality unless experts say no way! Thanks for your reply.

You're welcome, glad I could help a little. I've never had a Calamondin but I always read they're too sour to eat out of hand, if you like those fresh off the tree than the Kusaie might not be too sour for you. You could always buy it and keep it in the container and move it to wherever is convenient for you. I know what you mean about missing out on a citrus variety. I was all set to buy a Tavares Limequat tree only to find the nursery had run out and they have none in propagation for the furture, and I can't find it anywhere else!

Kusaie is a lot less sour than rootstock Rangpur, should ripen yellow, not red.
Probably a just under ripe green Calamondin is closer to the flavor, even then a bit milder ? I would say worth getting.

I see you intend to plant "Vainglia Orange". Same as this?

If this is the same one I had it is an acidless orange that tastes nothing like orange juice!!. I had 5 gallons of fruit and it was the blandest orange I'd ever tasted. It was sweet only with no tartness and when I stopped expecting it to taste like an orange it was OK. In then end I cut off the main branch of the tree and now grow blood oranges where the vainiglia orange was. I don't recommend this one to anyone!

I will go and get Kusaie in the morning..Been hosing down with winter rains so didn't venture out today.
I will put the Vainglia in an area where if I am not rapt in the flavour I will ignore it.
I guess I like my citus with a bit of a bite so maybe Kusaie will fit the bill.

hi ive only eaten the rangpur lime,i found it very bland and quite dry,i think its about 80% pomello,in india its added to mandarine juice.I would imagine straight from the tree it would be a lot different ,can be quite seedy too. Hope this helps artie

Kusaie, is more or less commonly grown as a door yard tree in Hawaii. The fruit peels easily, and according into H.J. Weber's account, " the pulp is tender and melting". However, most important Kusaie is very precocious and quite productive, growing rapidly, more so than any other lime. Kusaie's acid content is 6.75 percent, so it is slightly lower then Key and Tahiti limes. All in all Kusaie is a fine appearing, excellent acid fruit and is worthy of careful consideration.* I think it would also be interesting to try it as a root stock, to see how it produces. Another very precocious tree that I have used, the Thomasville Citrangequat, makes an excellent root stock. - Millet (946-)

Picked up a beautiful tree that hopefully will fruit in the seasonal "gap" period that we're in at the moment in NZ for lemon/lime citrus.
