They do take their time to sprout-and do not like cold drafts. Anywhere warmer and lighter- or even in dirt you can put them? I stuck mine outdoors one spring and forgot them, they were watered from the aerobic system spray once a day. They also got frozen last winter in Texas snow (truly rare for Houston) and lived without help-however, they are in deep cover from pines, oaks, hollies, yaupon and etc. Ummm, when you find a warmer place, try warming the water to at least tepid/warm when you water.
