I will remove my pansies once the sun gets too hot and put them in dappled shade where I'll let them grow. During that time I trim the plants up so they look neat. Then in the fall I'll replant pansies into a sunnier location where they may overwinter (depending on the conditions) and have pretty plants again in the spring. It's probably easier to buy new ones, but that's how I do it.
Right now I have petunias and geraniums in my flowerboxes. They both can take the heat.

Here is a link that might be useful: my webpage

I live in Webster,Chase pitkin on Holt Rd has some nice mums. I never buy them but these are so pretty. They also had some nice sun annuals. If you know Grossmans they might have some nice plants. RTE 250 in Penfield. Check out their website, www.grossmans.com for coupons and sales. Lots of places get in new annuals all the time. For fall people like mums,cabbages and more pansies. Check around . Trolley Bed in Victor and Bristols are other options. Check in almost where they sell plants and you'll find something. Id ask about mums and this heat though.

Thanks for the tip about the pansies, Aurore, I'm going to see if I can salvage mine for next year.

Thanks, Jeanie, for telling about the Grossman's website. I don't often think to check there, and it's great that they list all of their specials online.

It's a bit of a drive, but Wayside Gardens is quite extensive. They don't always update their web page, though.

I might have bumped into Jeanie at the Holt Road Chase Pitkin! I got mums there too -- had a hard time deciding which color, they were so pretty!
