$50 Gift Certificate can be used to purchase anything on the site (seeds, dahlia tubers, and flower arrangements when flowers are blooming). The gift certificate should be delivered immediately as a digital file (let me know if you don't receive it). I don't know of a way to make it automatically apply to a purchase at checkout, but if the recipient tells me the code that is on the lower left corner of the gift certificate I will make sure it gets applied to whatever they want to order that is of that value. Each gift certificate will contain a unique code, so it can be used by anyone but can only be used once.
