Heat Tolerant Seeds

    The summers just seem to be getting hotter. If you live in an area with hot summers, you might be wondering what you can grow successfully during these months. I have certainly planted a lovely patch of leafy greens and herbs just to have them bolt and rush into flowering before I could get my harvest. I hope that you can avoid our past mistakes by choosing the right plants for your climate.

    Generally when the temps get above 85 most plants tend to bolt and go to seed. Heat tolerant plants just smile back at the sun.

    Order today and plant in your spring garden.
