A white and a blue clematis - Your recommendations?
I'm planning to add a white and a blue clematis next year to grow up the sides and across the top of our pergola.
I was thinking of SWEET AUGUST but is there another white, tall(grows more than 8 ft) and northern hardy to consider?
Also want to add a blue one but haven't a clue yet what would be a good choice.
I already have a deep burgundy colored one and a purple one but they don't grow very tall.
Would appreciate some recommendations and places you've purchased from online.
Thanks for the help.
