One of the first steps you take when you are figuring out your gardening schedule is find your USDA Zone info. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

One way of estimating when to plant scabiosa is to use the USDA zone info for Munster.

Planting Calendar for Scabiosa

Frost tolerance for scabiosa:	Tolerant of some frost.
When to plant:	Up to 5 weeks before last frost.

Since scabiosa are moderately cold tolerant you can plant them just a bit earlier in the year than plants that are more sensitive to the cold.

The earliest that you can plant scabiosa in Munster is February. However, you really should wait until March if you don't want to take any chances.

The last month that you can plant scabiosa and expect a good harvest is probably September. Any later than that and your scabiosa may not have a chance to really do well. Starting your scabiosa indoors is a great way to get them started a couple of weeks earlier.

Last Frost Date

The average date of last frost is April 15 in Munster. It might get as low as -15°F during the coldest months of winter.
