Asparagus seedlings

They should be dormant now, so won't do much if you plant them out. Although you could do it now, being such young plants I'd be inclined to keep them potted up and sheltered until spring (March is usually the month for planting out in the UK.)

If your seedlings grew enough to tell which were male and which were female plants, you may want to consider ditching the females if you have more than you need.
