Good to see you here. The pink front and center is an Astilbe.

The tall purple appears to be Phlox paniculata.

The blue on the left looks like Hibiscus syriacus. I can't make out the white beside it, possibly more Phlox.

The spiked grass is most likely an Iris.

The low red flowers and the white at the front look like they are an annual like Impatiens?

I agree with peren.all's IDs.

There is also a just opening pinky purple in the upper right corner that looks like Lespedeza thunbergii 'Gibraltar'.

Aww bless thanks peren :0) good to see you too

the spikes, could they be gladiolus? Tried them before, but their not keen on my soil. They came up lovely, but afterward the bulbs rotted.

Is it the bright pink in the centre that's astilbe?

Nhbabs - do you mean the bush next to the hydrangea?

Is Hibiscus syriacus, the same as rose of Sharon?

Would you guys consider any of these to be invasive?

I just read that in the UK Hibiscus syriacus is sometimes referred to as Rose mallow, but here is called Rose of Sharon. I have heard complaints and praises for this one.

Phlox paniculata can seed if not deadheaded but are easy to dig/pull out.

Sophannah, in the US Rose of Sharon means Hybiscus Syriacus. In the UK iT means Hypericum calycinum. A good example of why the botanical names are so important. I've never heard H syriacus called by anything other than its botanical name here. Never heard it called Rose Mallow. If anything, that name might possibly be applied to Lavatera trimestris. Btw the colour of the Hibiscus has been doctored. They're not really that blue. Glads do best if you lift the corms and dry them off to replant. They do tend to rot in out climate.

Yes, Dawn, the one in the upper right corner of the photo, to the right of the Hydrangea is the Lespedeza.
