Agastache, Heather Queen; Shipping and Handling Charges

Is the Agastache, Heather Queen (Agastache cana) the same as Hummingbird mint, mosquito plant or bubblegum mint (common name)? is it of the Lamiaceae (mint family). Does it come in only as seeds?

I am not sure what you are referring to by "Hummingbird mint". We have a hummingbird sage, and sages belong to the mint family also, so I wonder if you are thinking of that. We have never heard of agastache being referred to as mosquito plant or bubblegum mint. Agastaches usually have a menthol or licorice flavour (or none at all), but none could be construed as "bubblegum"-like or having anything to do with mosquitoes.
Yes, currently we only offer it in seed form. It is very easy to grow from seeds.

There is an added price of 50 cents for each potted plant order, correct? but is $8.00 shipping for each plant or the package regardless of how many plants?

The $8 is a per-order charge, not a per-plant charge. So, for example, if you order 6 plants, you pay $8 + 6 x 0.50 or $11. This is the charge to New Mexico; the shipping charges to other destinations are different.

Regarding seed order, there is not postage, only $5.00 handling charge correct?

Correct.

Do you really ship outside of Canada? I live in New Mexico.

Oh yes! Have been for decades. Our plants are pre-approved for shipment to the U.S. We take them across the border, handle all the border formalities, and then ship to you from Buffalo.
