First bloom for newly planted bulbs takes longer than established bulbs. They'll be a week or 2 longer. The cold slows the growth as well. Deeper planted bulbs will take longer as well. These are all tough bulbs, they'll be fine. Don't pull up anything. Where bulbs are blooming now is because their exposure to the sun is most direct right now. All bulbs will bloom eventually, unless they're in a waterlogged poorly drained site. Deciduous shade is fine for bulbs, except the alliums, which need full sun.

Crocus sativus will produce more flowers next fall, if the foliage is exposed to maximum sunlight and remains green as long as possible. You didn't indicate when they bloomed, but the foliage will usually last for 4-5 months afterward(about mid-winter here). I don't think you need to be concerned about temperature, as long as it is above zero degrees, they should be fine. Some references list their hardiness as -30°F, others at -20°F., with a thick layer of mulch(4+"). You might consider using some heating tape (the type used for wrapping pipes to prevent freezing) and burying it a couple of inches deep in the planter's soil, for use on extremely cold nights. It is fairly inexpensive, available at most HD, Lowes & Hardware stores and operates for pennies a day. I grow a number of fall blooming bulbs, including several species of Crocus and enjoy them immensely! Good luck! :Rb

I've had great luck with this method. I've planted mostly grape hyacinths (muscari) and tulips together. The most fantastic success was a large, low, cobalt blue pot with several packages of 'Apricot Impressions' tulips and 100 grape hyacinths. So pretty. I've also used white daffodils with light blue muscari 'Valarie Finnis'. That was a lovely and soft combination. One fall I found small quart-sized perennials on sale for next to nothing and tucked one or two into each pot along the very edges. Those came out beautifully - the emerging foliage of heuchera and pulmonaria and creeping veronica was so fresh and lovely with the bulbs. They were like miniature gardens in a pot. Violas and pansies could be tucked in, too, once available in the spring. And little lettuces would be cute, wouldn't they? I know I planted a pot with a red tulip and narcissus 'Jetfire' that turned out well, but I'm more partial to the height difference with the grape hyacinths and the taller tulips and daffodils. The little muscari also bloom for such a long time that there is less of a problem with planning the bulbs to bloom together, which is what I like. I haven't tried crocus, chinodoxa, scilla, etc. but I'm sure they would all work well. And yes, you can really stuff them into the pot "cheek to jowl"! Like Dennis said, leave some room for "heaving" and "flexing" when the bulbs are planted so densely. I've planted them in fresh potting soil, used potting soil, and both with and without bonemeal or bulb fertilizer and have always had great results. After the blooms are spent, the pot can be shuffled away to allow to foliage to decline in privacy, which is nice. It is also easy to decide where to plant the bulbs that you've grown in pots when things are up and growing. Empty spots in need of spring color are easier to note in April than in September, after all. I would recommend finding and using bulbs that bloom at approximately the same time (early, middle, or late spring) for the best show. I keep my pots stacked in an unheated mudroom. I water them very lightly when I plant them and then water them lightly again in mid winter. I move them outside in maybe mid-late Februaryish when I start seeing little bits of growth and want them to slow down and "become one with nature" again. Of course, depending upon your climate and the fragility of the pots you're using, this might vary. By the time the bulbs go into deep clearance here I am done digging outside anyway, and my pots that held annuals have been emptied. It works out well for me to putter around in the relative warmth of the garage or mudroom with bulbs that are so inexpensive I am not required to feel guilty if I don't find a spot for them in the ground the following spring. Sorry for so much enthusiastic gushing! Just talking about this has me excited to get started again this fall! Adona

Thanks everyone!! It's such a joy to see the landscape popping with flowers instead of staring out the window at 6 ft. of snow. The little blue and white flowers are indeed Puschkinia and grow only a few inches tall--shorter than crocuses. They've naturalized through what I loosely refer to as the lawn, along with crocuses, violets & grape hyacinth. Sorry Rose, I couldn't begin to "divide" them--they're everywhere! It's impossible to walk across the lawn without stepping on them. I held the camera about 2 inches from the flower to take the photos. I have three fat buds on my hellebore 'Regal Ruffles' and what looks like a couple more buds on two others. This is the first time they've set buds since I planted them so I'm very excited to have Lenten roses for the first time.
