Hyacinth is planted alongside tulips and daffodils in fall, but it earns its spot for a different reason, the dense, 8- to 10-inch spike of small waxy blooms (blue, pink, purple, or white) carries a fragrance strong enough to fill an entire porch or entryway, which is why it shows up so often near doors and walkways rather than out in a bed.
How hyacinth fits zone 7's season
Zone 7b's frost-free window runs about 198 days, from April 10 to October 25. Hyacinth needs about 150 days from sowing to first harvest.
