Are they on the more or less affordable side (as compared to,say, Portland Nursery)?

Affordable, plus since they grow the annuals themselves they are better. Knowledgable staff. I love this nursery.

I agree with other commenters here. They are an old fashioned nursery growing many, though not all, of the stock they sell. They are a bit cheaper than Portland Nursery, but folks ( coming from a professional gardener) all green goods took much care DAILY before it reaches the consumer, and all of it is going to cost. That said, usually a more expensive plant can be (if you are a rare person who possesses natural observation abilities and common sense) a very good way to jump start a great garden.

Less spendy than Portland nursery.

Slightly cheaper, nice selection, they grow their own annuals

Yes. & concur with positive locally grown comments.
