They'll be fine potted up individually or a couple to a large pot, obviously keep them well watered.
Or you could plant them temporarily at a closer spacing in that fabled spare corner where we are told to heel in flowered daffodils, lifted leeks and so on! Lift and replant when your bed is ready. Don't worry too much about keeping the whole root system. it always seems to be a fairly scrappy affair and they grow away fine in the spring.
