Another option is to try "forcing" some bulbs in pots which would allow you to control the timing of flowering with much more precision. Assuming you have a suitable location for cooling the potted bulbs after they have rooted in for at least a month, you could begin forcing the pots after about 12 to 14 weeks of cooling over a range of time thereby guaranteeing that some are in flower on the desired date, flowering maybe 2 to 3 weeks from the start of forcing depending on the forcing temperature (that is a guess). There is plenty of online info for other spring bulbs, likely less for Puschkinia. I have always found hyacinths and Convallaria to be the easiest. Some keys to success are scheduling, proper rooting before cooling, using as many bulbs that will fit in the pot, weighting the bulbs down while rooting, and, most importantly, correct temperature management from beginning to flower.
