First, daylilies are not bulbs - they are fleshy-rooted perennials that are incredibly tough and hardy and can be planted anytime of year the soil is workable. Not all iris are bulbs either and many varieties can be planted similar to the daylilies. Most true bulbs that bloom in spring need a period of vernalization to set roots and develop flower buds, that's why they are planted in fall. If insufficient vernalization is provided, they won't bloom, or at least not that first season in the ground. The pre-chilling of spring flowering bulbs in warmer climates achieves the same purpose. IME, January is pretty much the limit on when one can plant spring flowering bulbs and expect them to bloom that spring. And that may be difficult to accomplish in zone 5.....I'd imagine your soils to be pretty well frozen at this time of year :-) The other aspect is that spring flowering bulbs available for sale this late in the planting season tend to be leftovers and of lesser quality....the good stuff's already been sold! One needs to maintain dormant bulbs under proper storage conditions for them to remain viable and they simply don't last forever out of the ground. If you don't have any bulbs on hand to plant now, I wouldn't recommend searching any out. The combination of unsuitable planting conditions (frozen soil or snowcover), the lack of quality bulb sources and the lateness of the season will just serve to produce unsatisfactory, frustrating results. Wait until later when the soil is workable and the weather cooperative to plant perennials like iris and daylilies. And look for already started bulbs (in containers in leaf and often in bud) available at garden centers or other plant outlets when they come in season - February and March in my climate, perhaps a bit later in yours. Or wait until fall to plant the dormant bulbs for the following spring. And pretty much any spring flowering bulb will work in your climate. You just need to do some research on what are bulbs (corms, tubers, etc.) and what are really rooted or rhizomatous perennials.

I just purchased six of these plants & was planning to put them in the ground tomorrow. Im in Southern Ohio and it looks like Summer is coming early this year (our temp was 85 today). We're supposed to get some rain next week so I really hope its not to late to plant these, especially since I just bought so many of them.

Seasoning time for bulbs is like onions and garlic- you can eat onions and garlic right out of the ground, but if you want to store or ship it, you need to let it cure a bit first. Bulbs are like that too. If you plan on transplanting them quickly, you can pull them and use them fresh. But if you want to hold them for replanting later, you need to give them time to season and really go on hiatus before storing them. I've moved around daffodils, crocuses, and hyacinths no problem without seasoning if I do it directly. I also don't treat bulbs like a lot of folk do. When I get a package, I pot them up and grow them out for a year first before putting them into garden spots. After their blooming time is done, I empty out the pot and let the bulbs season till it's planting time in the garden later that year. It takes a year of patience, but most pots divide a lot, so I end up buying half the bulbs I would otherwise. Anyway.. I came to give an update. I planted in the first bed with plants, and the second bed will be finished by the end of the weekend. I haven't done any bulbs yet, because I figure I'll do all those at once when I'm doing other bulbs in the yard.

Me,too. Planted 2 one fall. They were root bound which I'm sure did not help. They did not come back. I also switched to spring/early summer planting and they were fine BTW, same for echinacea. I pass up good bargains in the fall because dead is not a bargain
