What is the climate where you are? I will assume you are talking about lawns rather than the grasses associated with prairies, pastures, orchards, meadows, etc. There are warm season and cool season grasses and for each of those several species and numerous varieties to chose from. Some grasses will germinate in a week others will take much longer up to 3 weeks depending on climate and season. Preferred seeding of grasses in the Midwest (a temperate zone) is in late summer/early fall, when soil is warm, plenty of moisture and air temperature is cool. Fine bladed tall fescue mixes are commonly used in the Midwest because they are tuff, deep rooted and draught resistant. It is best to seed tall fescue at a rate of 10lbs/1000 square foot. You will hear of 6lbs and 8 lbs per 1000 sf but it is not recommended if you are looking for a dense lawn with no feel of the individual grass plants under foot. All lawns take a full growing season or more to mature.
Cosmos seeds typically take about 7-10 days to germinate when planted in warm soil with adequate moisture. However, germination time can vary depending on the temperature, moisture levels, and quality of the seeds.

Papaya seeds generally take around 2-4 weeks to germinate. Providing optimal warm and moist conditions can help speed up the germination process.
Depending on factors like the soil's temperature and its moisture content, corn seed should germinate between 5 to 15 days. If after this time it has not germinated, then these are two factors that need to be investigated
Rubber seeds can take between 10 to 21 days to germinate, depending on the environmental conditions such as temperature, humidity, and soil quality. Some varieties may take longer to sprout.
Blackberry seeds typically take about 3 to 4 weeks to germinate.
Mint seeds typically take about 7 to 14 days to germinate.
Peppermint seeds typically take about 10 to 15 days to germinate.
Pineapple seeds typically take about 2 to 3 weeks to germinate.
Lettuce seeds typically take about 7 to 14 days to germinate, depending on the variety and growing conditions.
Sunflower seeds typically take 7 to 14 days to germinate, depending on the conditions such as soil temperature and moisture.
Cosmos seeds typically take about 7-10 days to germinate when planted in warm soil with adequate moisture. However, germination time can vary depending on the temperature, moisture levels, and quality of the seeds.

Sunflower seeds typically germinate and start growing within 7 to 14 days after planting.
Yes, grass can germinate in cold weather, but it may take longer compared to warmer temperatures.
Mint seeds typically germinate within 7 to 14 days when planted in the right conditions, such as moist soil and warm temperatures.
Strawberries are usually grown from runners from the parent plant not seeds
