I did augment a few areas by transplanting some sprouted tulips this spring, as there were a few bare spots. Still, with another 100 bulbs or so this fall I think this area will be very impressive next spring.
Provided, of course, that the zombie apocalypse does not occur between now and next spring. Thnking further, this will still be an impressive display even if zombies take over, since they have no use for tulips, but there will be few if any humans to see the floral display.
