Coreopsis, Threadleaf Coreopsis, Tickseed 'Route 66'

I bought three of these plants in August last summer in 3 inch pots and they weren't much to look at then, but they grew and flowered unt...Read Moreil the hard frosts came. This year they increased in size dramatically (growing in full sun and sandy loam soil) and continued to increase throughout the summer. They have been blooming non-stop from June until now (mid-September) and I'm sure they'll keep on blooming until frost. I have not had to deadhead them. They don't flop, but I haven't given them any fertilizer (which can make plants like coreopsis that like lean soil do) and we've had good rainfall all summer, so I've never had to give them any extra water but a couple of times, and that was only because I had added new plants to the bed they were in and watered the entire bed. I have not had any trouble with mildew. They look nice growing with Russian sage and agastache.

In July it was in full bloom the first year I put it in and now beginning of August after about 50 blooms later all spent it is slowly starting to bloom again. I've cut off all of the spent blooms basically so I can share the seeds but also hoping it will encourage reblooming which it is starting to do some what so far.
I don't know if this is just the plants characteristics because when I did plant it I did give it a good dose of time released fertilizer.
But all in all this is a plant worth having just gorgeous in full bloom.
Update: it is now almost the end of August to be exact the 25 and this plant is already full of buds and blooms for the second time this season.and some of these blooms are really good sized the size of a silver dollar.
