Morning Glory in Zone 11a & 11b
Ipomoea purpurea
When to plant morning glory in zone 11b
Zones 11a and 11b share the same average frost dates in our data, so this page covers both.
Method: Direct sow: Direct-sow outside. Morning Glory doesn't transplant well, or doesn't need the extra time indoors.
| Start indoors | Not typically started indoors |
|---|---|
| Direct sow / transplant outside | Jan 15–Jan 22 |
| Estimated bloom | Mar 31–Apr 7 (~75 days after direct-sowing) |
Spacing: about 4 square feet per plant (square-foot-gardening spacing). Mature height: 8-10 ft.
Morning glory is less a flower you plant and more a vine you manage. It starts twining and climbing within days of germinating, and in warm zones it will self-seed aggressively enough to become a recurring weeding chore rather than a one-season planting. The payoff is funnel-shaped blooms in blue, purple, pink, or white on a vine that will climb 8 to 10 feet given the chance.
How morning glory fits zone 11's season
Zone 11b is frost-free in this dataset, so frost is not what limits the calendar here. What you can plant, and when, comes down to summer heat and daylength instead.
