In the fall of 2009 and again in 2010 I bought a pretty good number of bulbs from McClure and Zimmerman (https://www.mzbulb.com/). In each of those orders they threw in five tulip of the variety ‘Van Eijk’. There are still ten plants growing where I planted them although we only have six blooms this year. Tulips are not terribly long-lived plants, certainly not in our area, anyway, so the fact that these are still blooming after 8 or nine years is pretty good. They’re quite bright and a sea of them would be more impressive than the six I have, of course. In general, though, I’m more a fan of daffodils, which seem to live forever and form large clumps over time.
