In Cleveland you can figure out when it's the best time to plant steirodiscus by reviewing the USDA zone info.

Planting Calendar for Steirodiscus

Frost tolerance for steirodiscus:	Tolerant of a very small amount of frost.
When to plant:	Up to 3 weeks before last frost.

Since steirodiscus do ok in moderate cold you can plant them slightly earlier in the year than more sensitive plants.

The earliest that you can plant steirodiscus in Cleveland 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 steirodiscus and expect a good harvest is probably September. You probably don't want to wait any later than that or else your steirodiscus may not have a chance to grow to maturity. Starting your steirodiscus indoors is a great way to get them started a couple of weeks earlier.
