Is that full summer in NJ?

If so, then I suspect that any Allium will be in flower..?

Not the ideal time, but if they are there...

I don't know is the real answer - I have no idea of your season/climate etc...

Do you have them as dry bulbs?
Are they in a pot and flowering?

Lots of boring questions need to be asked... :)

But, stick around because someone on GoY will know.

In new jersey december is winter and it will get colder in janurary and feb before starting to warm up in spring. They are dry bulbs that I ordered online without doing the proper research in regards to planting time...right now its mid 30's and 40's and getting colder in the next few weeks

Welcome top Goy Newtoplants and a happy christmas.

Personally i would not plant out now but would if you can pot then in to pots then you can replant out in Spring.

when you say 30 -40 I assume you mean fahrenheit not Celcius. [0 centigrade 32 F] The compromise is to plant them in pots and then when the weather warms up, then you can plant them out where you want them.
I started mine off in pots, the bulbs buried 3 x their height deep. They will put roots down and probably out the bottom of the pot too, then you will get top growth.

hope this helps.

That is more or less what I used to do when I lived in Toronto, Ontario, Seaburngirl. Although Ontario's winters are usually marginally colder than the north-eastern U.S. it used to work. And yes, N. America uses the fahrenheit scale.

I still use 70-80's for summer temps but 0 -2 etc for winter temps. mind I flit between cm and inches and still talk in old money too. 9 bob for a packet of crisps! I remeber when you could get them for thruppence.
Youve lived in exotic places Sarra, North east coast of Sunderland and now just inland from Hull in my case.

thankyou all for the responses. I will definitely pot the bulbs immediately. Should I use one bulb to one appropriate sized pot? And do I keep these pots indoors, in garage or outdoors? ( garage is not heated but stays a couple of degrees warmer than outside )

Garage should be fine. You don't want them too warm.

I would suggest planting in individual pots. You can then plant the complete pot in the ground for next season and then replant the bulbs properly when the foliage has died down in the summer.

Warm for New Jersey! As long as the ground isn't frozen, you can plant the bulbs in the ground. Planting this late may delay foliage and bloom, slightly, since some species like to form some roots in the fall, before hard frost hits.

Unless these are Californian Alliums (and there are some drop dead gorgeous ones from there) then they are likely to be natives of the Russian/Mongolian Steppes. They are as tough as old boots as long as the ground is not waterlogged.Either plant out as Tug says or pot them, but no mollycoddling, they need cool roots.

thankyou all for your valuable advice- because I might want to do some remodeling of the garden area its ideal for me to plant these in pots given the reccomendations. If I had an established garden i would plant them in the ground but Im not too sure right now where Id want to put them etc. Do wintering bulbs in pots need to be watered? The local nursery told me to prune my potted elephant ear down and then wrap it in plastic and put it in the garage until it starts to get warm...is this a viable approach and can the alliums be treated the same>?

Without knowing which Alliums you are growing, it is hard to give a definite answer. Things like Allium Globemaster or A. karataviense are winter growers so they do need water and cold for the roots to form.
Allium dichlamydeum definitely does not like frost and is a Summer grower.
Having said that, most of the ones sold by big companies are cold hardy, so they do need watering over winter. Try to keep them moist but not drowned.

Tropical and subtropical bulbs, such as Elephant Ears, Dahlias, Cannas, or Caladiums, like to be kept dryish and cool--but not freezing--over the winter. Hardy bulbs, such as Tulips, Daffodils, and most Alliums, like to have cold, moist conditions over the winter, to encourage root development. Mediterranean bulbs, such as Gladiolus or Freesias, when grown in the summer in a temperate climate, like to have warm dry conditions over the winter.
