These are the white fragrant crinum which I think is Americanum.
The original plants are over 25 years old from old homestead.
Have two for postage - not quite blooming size.

would they grow in zone 4-5?

Do you still have them?

Yes, do you still have them? And would you happen to have a picture?

Will be tuff to get them to bloom. Otherwise, yes. But bulbs must be lifted and stored or potted up and stored. I over-wintered some both ways last year.

Still interested. I gave most of my crinums away and then, wouldn't you just know it, the mother and 2 babies up and drowned on me. I had them in a very large pot and went to separate them but only found mush. This was quite some time ago when I knew what the word 'thunderstorms' meant.

Please let me know if you still have one to give away. Postage is not a problem.

Growing verrrrrrrrryyyyyyyyyy SLOW. I have 1 in the ground **, 5 in one huge pot (1), 4 smaller ones in 4 " pots (2).

Perhaps our environment here, but they are slow to grow. Of course, they cannot be left in the ground here.

** The one in the ground I wintered over in a pot that it had been growing in during summer 2016 in my absement.

(1) I pulled these and stored them like Cannas in my basement in cardboard boxes.

(2) I wintered those over in my basement in containers.

Thank you. I wonder if they are like some of the tropicals I have read do not do well if they are moved.

I will try the all year grow and see if that works. I cut way back on my tropicals so I can use one of the extra large pots and see if I can grow them all year without movin them and see if that brings results.

I know you can grow them in large pots. Also know from experience that they can take a very light frost. But I would guess that in PA they wouldn't make it outdoors thru a winter. Crinums grow wild in swamps around Houston.

But wait! Just re-read your original post and saw that they've been growing for 25 years. Maybe just copy their environment.
