Milkweed seeds

[Tiniii]

I'm new on this site and found loads of great ideas already! 
I have some homegrown red Milkweed seeds to swap - see http://butterfly-fun-facts.com/images/tropical.milkweed.red.6.jpg.  Although not a veg / allotment plant, they are meant to be great for attracting butterflies to the garden! 
I'm interested in swapping for either horseradish roots or jerusalem artichoke preferably.  Also have some spare veg seeds from last year's BBC Grow your Own campaign (think they are carrots, beetroot, lettuce, squash, and something else). 
Anyone interested?
Good work people, and wishing you all a very happy gardening year 2010!
