Shipping Quick Info

Grassy Knoll is a labor of love since 1998.

We have the largest selection of passiflora in North America and regularly sell to universities and the top passiflora experts in the world. We make every effort to ensure that the plant is free of virus and correctly identified, usually waiting to see the plant bloom, which can take years and years. We also try to take our own product photos so you know what specific attributes your plant would have.

Everything we sell is grown, propagated and shipped from our nursery in Oregon, we do not outsource anything.
