Vietnamese Coriander

Just bought some Vietnamese Coriander , many website are saying that will die down to 4c , but as it part of the persicaria family will the roots be frost hardy and it will come back next year?
any help?

 

I'm sure I have a weed in my garden that looks just like that.

 

That's exactly what I was just thinking.

 

thank you both , very helpful , that`s the same thing I told my miss when she bought it , .........at least it look tropical , should I let it die and tell her ....sorry but that the advice I got from the guys

 

btw she bought liquirice and curry herbs as well .

 

ive got it sal,just put your pot in the greenhouse over winter and will it will be fine i love it,soooo strong yum x

 

thank you Joolz , finally a good answer , been looking on internet with no luck , I will divide and try a bit outdoor just to see if it`s roots hardy.

 

Im not sure if it is root hardy here sal,i tried dividing mine this yr but it didnt take,maybe i should of waited a month longer
There is some info on youtube on how to divide i think
Its that strong in taste i dont need more plants but its good to try x

 

thank you again Joolz , I wish I had a bigger garden just to create a tropical herbs corner , last January while in Thailand I stopped to side road noodles house and it was amazing to see the herbs/spice they where growing in small pots on the side of the road , lotus , ginger , lemon grass , rice , blue pea to coloring the rice and so on.
ps any tips of how to use and where to use it?

 

I use it in salsa and salads yum ive never tried to dry the leaves to grind but maybe i should and store it it comes in handy as a back up aswell, as now my normal coriander is going to seed which vietnemese doesnt..well it never has for me i will have to do some research about it,i bought mine from the herb garden here in derbyshire 2yr ago but ive noticed it for sale now in other nurseries this yr,its def good to have if you love coriander..more concentrated taste
I found its got a fast growth rate aswell sal,dont know what size pot you have it in but keep an eye on repotting it soonish if in a small pot
I hope you achieve your tropical herb garden soon..i can pick your brains then x
This seems good info..http://aidanbrooksspices.blogspot.co.uk/2007/10/coriander-vietnamese.html

 

I`ve tryed few tropical herbs/spice this year , but all in bits .....
got lemon grass as every year , ginger , nut grass , galangal is doing fine as well , curry silver leaves , liquirice (just bought it), colocasia as part of edible tropical , chayote (really fast growing) and so on.
I would try outdoor , as actually my red dragon plant has survived outdoor with a bit of mulch and they are from the same family .
but the way don`t confuse the 2 normal coriander and vietnamese coriander are 2 different plant , not the same family at all .
coriander , available even from Tesco

and vietnamese coriander it`s actually a persicaria , some persicaria are UK native or growing wild in Uk .

 

It could be root hardy sal,ive got mine in a large plastic pot and only leave in the greenhouse(bubblewrapped) over winter and as darrans just reminded me,last spring it got mould on it and still made a full recovery so yes maybe with mulch it might be ok planted out i might try it,its one less plant to babysit i cover everything with straw and now its more readily available i wont be as nervous if i loose it to a bad winter

 

Joolz , the best way of find out is to cook it ; )

lemon grass , lemon leaves , basil , curry plant all coming from my garden ...then chop chop , chop chop and wualha`
Thai Curry chicken , with eggplant and vietnamese coriander.

It actually really strong , a 10 out 10 herb , taste way better then the real coriander.

 

Did you decide to plant some out sal? i tried to split might again but its just to tight knit so ive hacked it down and put it in the greenhouse again i might plant it out next yr and see if i can get a healthy chunk from it then if it spreads,keeping it compact might be my problem

 

went to will Giles in Norwich and seen it a massive plant outside , will keep indoor this year , in a pot saucers with water and see what uppen , but I`m sure it will survive outdoor in a protect part of the garden.
