Yes, though unless they have been in temperatures under 40 degrees for about 60 days, they will not bloom. Spring bulbs have a genetic instinct to begin the process of producing bloom after experiencing the cold of winter in preparation for spring. If you plant the bulbs now, they may shoot forth leaves and that is ok. The foliage will gather nutrients from exposure to sunlight and to feed next seasons bloom. So go ahead and plant. Instead, You could also force the bulbs inside by putting them in the refrigerator for about 50 - 60 days and then planting in a container inside where it is warmer. Put in a sunny window and delight in tulips in the summer. When the bloom is over, plant outside and let nature do its thing for next year. Plant each bulb at the depth of 1 1/2 times the size of the bulbs. I love bulbs, they are so low maintenance and very dependable. Note that bulbs love phosperous. I save all my egg shells and when dry crumble them in my garden over my bulbs. Free fertilizer.
