When will my order be shipped?

All plants are shipped within two weeks of placing an order.

Is it okay to plant in the winter?

Yes, as long as the soil is not frozen. Planting native perennials in winter and early spring gives your plants a head start before the summer heat arrives.

What if it’s too cold to plant where I live, but I want to buy a plant before it sells out?

Dormant plants can safely be kept in a basement, garage, or cool room until you are ready to plant in late winter or early spring.

How will my plants get delivered?

Most orders are shipped on Monday or Tuesday via UPS Ground, which depending on the destination takes between 1 to 4 days.

Are your plants shipped in their containers?

Yes, all our plants are shipped in their growing containers. The majority are grown in containers that are 4.5 inches wide by 5 inches deep and 32 fl. oz. / 946 ml in volume.

Do you guarantee your plants?

We guarantee our plants to be healthy, ready for planting and correctly named. We are not able to guarantee whether a plant will grow in your garden as there are too many circumstances that are beyond our control.
On rare occasions, a plant shipped dormant may fail to emerge from its dormancy. If this happens, please let us know. If you are concerned about a plant, please contact us within 14 days to let us know. If we can’t help you make it grow, we’ll send you a new plant or issue a refund.

Can I return my plants?

You can return your plants if you no longer want them once they arrive. To receive a refund (minus 20% restocking fee) the plants must be returned in good condition. Return shipping is the customer’s responsibility.
