Help Identify an old strain Unusual

[Darksidedog]

Back in the early 80's, i popped a number of random seeds that dated back at least from the late 60's.
One of the plants was extremely unusual.
It was a perfect Xmas tree shape (no pruning) and was an unusual shade of silvery/blue/green with thin leaves of 9 fingers.
The most unusual thing about this plant was the behaviour exhibited during rain. The branches would lift up close to the main stem and then the whole plant would lie down.
The first time this happened i thought that it was storm damaged but when the rain stopped and the sun came out the whole plant stood up again and opened up as if nothing had happened.
The plant never completed flowering but that which I tried gave a very weird shimmer effect to everything. "Rhubarb and custard" like.

Would love to have any clues as to what the plant type was, never seen anything like it since.
Grateful for any help.

Now, that is something that i've never heard of before. Would be a trait that i would think would come from monsoon areas?

Welcome

Having grown many different herbs/flowers/etc whenever there is a deep soak rain, 1-3 days for example all of my plants lie down.

The first plant that comes to mind with a super nice Christmas tree, blue/green, and lies down is Colombian.

And in the 60s Colombian can be responsible for all of the ganja travelling much of the world, to Jamaica, Australia, America, etc.

This question was posted elsewhere in the forum before i was guided to ask in this section.
The following member has i believe, very kindly pointed me in the right direction.
