I’ve purchased seeds from this company twice and both transactions were pleasant. I really loved the diversity and quality of the various seeds sold. My first purchase was three varieties of cherry tomatoes, lime basil, speckled lettuce, kale, French radish, cilantro and parsley. I called today and had an amazing 25 minute conversation about what seeds could work for my balcony garden as it transitions into fall. They are very knowledgeable, passionate and kind. I wouldn’t hesitate to refer friends or family to this small business as my preference is to shop local. I will be purchasing through them going forward as they were helpful and the quality of seeds are great.

I went a bit crazy this year and ordered seeds from large and small companies all over Canada. The Brother Nature website is enjoyable to browse, and I like how the seeds can be viewed by weather and light conditions, and perennials by hardiness zone. I feel that their prices, shipping offer, and the seed quantities are very reasonable. My Brother Nature order arrived in good time right along with the other seed orders placed at the same time, and their packaging was simple and environmentally-friendly.

I buy more and more seeds from Brother Nature each year! They offer excellent quality seeds, competitive prices, and great service! I enjoy the variety of seeds they carry and their seed envelopes have more info than your regular packet, even some history/origin behind the seeds, which I find very fun and interesting. Highly recommended.
