Just in Time for Mother's Day

The frost has officially retreated, and the quiet of winter is a distant memory. At Evergreen Farm, the "hush" has been replaced by a vibrant, rhythmic hum.

Our greenhouses are now glowing with life as thousands of tiny green heads poke through the soil.

 

From delicate trailing vines for your hanging baskets

to the sturdy stems of heirloom vegetable starts, the tables are overflowing. Every corner is buzzing with the energy of transplanting, potting, and prepping.

What’s Happening Now

  • Veggie Seedlings: Tomatoes, peppers, and herbs are being tucked into their starter pots.

  • Custom Baskets: We’re designing lush, colorful arrangements for your porches.

  • Spring Essentials: Early season annuals are reaching for the sun, ready for their new homes.

 

The air in the greenhouse doesn't just feel like spring—it feels like a fresh start. Come, catch a glimpse of the green before it hits the fields!

See you in the Spring!
