Q.Different Species Of Milkweed For Different States Not Stated ALSO, Food For Emerging Insects

Those 2 points are never addressed on other sites, even US gov’t sites. Would a small garden of 2-3 plants, or less, supply enough accomodation of plants or is a “meadow” size, or large beneficial? I have a small yard
