Allium bulb already coming - normal?

You can plant them now but tulips are best planted in November and prefer sitting on a couple of centimetres of sand, I plant my allium with sand also it just help prevent rot. With expensive bulbs like giant alliums / crown imperial fritillaria they get a handful of sand on top aswell. If your garden already free draining or sandy forget the last couple of sentences

Super, thank you for advice. Have to get sand now. "Clay, naturally wet" - that's what I've got. I mix peat based substrate in and make all beds bit raised.
(trying to resist not buying this season doble snowdrops, white muscari and yellow fritillaria as I've already have many bulbs)
