One of my friend from Thailand has sent me bulbs/roots of these plants. Because of language issue can't identify them, please help me in this regard.
Thank you

Kaleem, the second photo appears to be a Crinum Lily. I can't tell about the others as the photos aren't clear to me. They look like interesting plants though.

#3 reminds me of Costus of some sort: Spiral Ginger (Costus arabicus)

edited to add: I'm so not good at comparing photo's but check out C. speciosus at this link, the second photo in particular:

Well, now I'm not so sure after seeing the photo's in the database Crepe Ginger (Hellenia speciosa)

The second photo (painting) looks like Crinum americanum.

Kaleem: It's hard to get a good view of plant #1; can you post a photo of the leaves? I was thinking maybe Curcurma of some type.

I don't have an answer, but it's nice to see you Kaleem...waving HELLO

Hello Kaleem!

It's going to be very difficult to put a name to any of these, it's best to see the actual plant as they could be wrongly packaged. It would be very difficult trying to translate the writing on them!

The second one is a Crinum, but there are several similar Crinums. If it was growing naturally where you knew species grew it might be easier, a packaged bulb is a different story. Assuming it is the same as the photo shows, then it is still difficult as so many have been misnamed and species crossed. Finding out which Crinums are commercially grown in Thailand may help.

The leaves in the photo have been cut off making it more difficult, the short height could make it Crinum buphanoides but that is a guess.

If your friend has provided the names in Thai in a typed message or email, copy and paste the names one at time into Google Translate. It doesn't work every time, but you stand a good chance.

Oh, I should have added, when it doesn't work it is sometimes still fun.
There is a plants which translated to
'son-in-law died; mother-in-law buried him' (or visa versa, I forget).

funny how things translate sometimes

Hello every one
Thank you so much for the quick response. As per identification first and third one are gingers and 2nd one is Crinum. I was really confused, these are full sun or shade planting bulbs and you people solved my problem.
Do not have more photos as these were taken by my friend when he was buying.
Whenever these will sprout, I will post new photos.
Once again thank you so much.

Kaleem
