Hi everyone!

I was at Lidl last week and bought some bulbs of the following autumn flowering perennials: Kniphofia Tritoma, eryngium and physalis franchetti. The packets say they should be planted immediately (I bought them last Thursday before the Easter hols) I noticed yesterday that they seem to be sprouting in their packets

Is this normal? The problem is that I don't know exactly where I want to put them in the garden, especially since we'll be doing some patio-building work in the coming weeks. Would it be okay to plant them individually in small pots in the meantime before putting them into their final plsces (be it large pots or the ground). Does anyone have experience growing these in big containers? If so, any advice would be greatly appreciated! Many thanks in advance!!
