The grand modern tulips may also be classed with the hardy outdoor plants, as with slight leafy protection the bulbs live over winter in our most trying climates. In starting a bed order all early or all late flowering varieties. In no case mix the early and late sorts in the same bed. Plant at the North in October, about three inches deep and eight inches apart in all directions, but not in rows. Prior to severe freezing cover the bed with four inches of leaves, to be raked off in early spring.
When the bed is through blooming and the stems begin to wither, take up and dry the bulbs under cover. When dry cut off the stems, and keep under cover dry until time for replanting in the fall. After the bed is cleared it is planted with canna or German aster for late summer and autumn blooming.
