Each of our seeded paper Hearts are meticulously handcrafted in our studio, making them a perfect gift for Mothers Day, Valentine's Day, weddings, anniversaries and more.. Every Heart is one-of-a-kind, infused with a mix of perennial flowering seeds ideal for most North American gardens. The seeds are selected to support pollinators and butterflies. Hearts measure 3 inches across. Retail packs are presented in individual envelopes, complete with planting instructions. The paper is made fresh to order, with seeds remaining viable for up to 12 months. Bulk orders are packed without envelopes, though custom envelopes can be provided at an additional cost upon request. Please note that since these items are made to order, production time is required. We recommend placing your order in advance.
