Since we first started selling specialty cut flower seeds in 2016, we have had the privilege of helping flower lovers all over the world grow the gardens of their dreams. Over the years, we’ve sent thousands of envelopes full of seeds bearing our signature YAY! stickers to Slovenia, South Africa, and so many far-flung locations across the globe that lacked a local source for specialty seeds.
But in the last few years, many great new specialty seed companies have been started, and I wanted to take this opportunity to share them with you.
Every January we have our annual seed sale, but we often sell out quickly. Also, because of new export restrictions beyond our control, we can only send seeds to the U.S., Canada, and Australia, so if you need more help finding the seeds you need, these sources are a great place to look for specialty varieties.
Listed below you’ll find my favorite sources for seed here in the U.S., along with numerous suggestions for sources around the world.
Ardelia Farm & Co.
Based in Vermont, Ardelia offers more than 60 varieties of the highest quality sweet pea seed, much of which they grow themselves. You can discover some really rare, special treats, and be sure to check out owner Bailey Hale’s helpful step-by-step guide to growing sweet peas.
This Missouri-based seed company offers one of the largest selections of heirloom seeds (over 1,200 varieties of vegetables, flowers, and herbs) in the country.

Sarah conducts extensive flower and vegetable trials at her famous Perch Hill farm and school, which we had the chance to visit in 2019, and it was even more magical than I expected.
