Is it too late to plant seeds outdoors now?

I lost a lot of what I planted indoors (to the cat!).....I didnt plant anything directly outdoors yet, but was wondering if I could plant the following seeds now:

datura
nicotania
aster
cosmos

would really appreciate some advice from the seasoned gardners.

thanks/cheers

KHT - I had to laugh - here our window is just really opening!! I planted the veggie garden on the 4th of July one year, and it was a wonderful garden. We had a frost on may 30 and it was downright chilly last night. First frost of fall can come at the end of August...small window, indeed.

I'll plant them this weekend!!! Will that work?

I'm still sowing new things as I find them. I sowed nematode marigold through some tomato patches 4 days ago, and they germinated yesterday.

Still sowing here, too.
Most things need 90 days or less to bloom or ripen,
so if you have at least that many days left in your
growing season, you should be fine.

Just starting to sow here in WPA-had hard frost night before last. Never plant anything out before Memorial day-learned tht over lot of lost plants. In 1974 when one of the hurricanes I think it was Agnes or Hazel swiped the applachians I lost 400 tomato plants on June 14 to 14 degree weather. Replanted the next day and lost them the next night.

Just sowed nicotiana today because I lost the seeds. (they were in my car)I hope they still will make. I also found some cosmos seeds I'm going to plant in the morning.

Pebble~ We still plant things around here till FROST. In june I can still plant anything that will make in 90-100 days or so, then in late july I plant the first of the Fall garden stuff you know greens and brassicas, carrots, biennial flowers can also be planted pretty late, they're not going to bloom this year anyway.

I'm with Dori...still planting in Michigan...just depends on your areas and the plants in particular.

Gonna plant them as soon as the hail stops....what a funny day weatherwise today!
thanks for all the advice.

Since I have so many, I thought about just planting seeds for perennials all summer here. Is there any reason (aside from watching the heat) that you can't?

Rise, are you going to plant them in containers, or direct-sow?

If you are direct sowing perennials, you run a risk that they won't be large enough to withstand winter temps, but I think summer can be a good time to start some slower-growing perennials or biennials.

I've got several perennials that I thought I'd start this summer, either indoors or out, (depending on our temps) and keep them in containers in the crawlspace or a cold frame with cow manure (for bottom heat) until next spring.
