Some nurseries insist we are in zone 6, even though I think we're in 5 (or less during some winters), so I'll drop my vote. I am also always short of time. I remember planting tulips in my garden on late afternoons, after returning home from work, by candlelight - it was already dark outside. This means it must have been November. Every single one of them bloomed. So I'd plant them asap and just expect them to bloom a bit later than usual.

Thankyou so much for the quick response. I was planning on planting half of them anyway just to see what happened and save the rest. However now i think i'll just put em all out there and see what happens. Thanks again!
