Tulip in a Zone 11 season
Zone 11 gives about 365 frost-free days. Tulip needs roughly 120 days from planting. That leaves about 245 days of slack, so there is room for a late start or a second planting.
How to grow tulips
Plant bulbs pointy end up once the soil has cooled in autumn, early enough to root before any hard freeze. Where winters stay mild, buy pre-chilled bulbs and plant at the start of the cool season. They bloom as the weather warms.
