cold stratification?

last modified: last month

Trying to understand cold stratification. Many native grass seeds that you buy require cold stratification to germinate. So it is said in the planting instructions. But these varieties self seed naturally and seem to germinate fine in our warm (Texas) conditions. That is, you don't get cold stratification outside at all here. If seeds are dropped in the fall, they won't be cold stratified come spring. But they seem to come up anyway. So how do these plants spread naturally here? If you plant such seeds without cold stratification, will dormancy be broken if given enough time? Maybe a full year? That is, maybe cold stratification is necessary just if you want to germinate immediately after planting.
