Dianthus immediately comes to my mind. Beautiful and often fragrant flowers and then a persistent pleasing grey mound of foliage. My baths pink foliage looks lovely right now.

Geraniums seem to always look good--except when eaten by deer or four lined plant bugs.

Heuchera of course, sustain some great looking foliage.

The late summer, fall bloomin perennials are growing to be some if my favorites since they often have pleasant looking foliage leading up to their bloom time (so kind of a reverse to the question I started off with!). They then peak in flowers as other plants are petering out and then they age gracefully into the fall

I am working on reaaranging many perennials and trying to decide which ones to put in the most prominent spots.

Stokesia doesn't have a very extended bloom period but the foliage remains elegantly arched right through the growing season, as does Penstemon foliage. Rose campion & St. John's wort fall into a similar category.

Baptisia/false indigo has elegant foliage that's not bothered by either pests or disease throughout the growing season. My latest-to-bloom perennial with elegant foliage throughout the season and well into October is toad lily.

and variegated iris:

I hold Hosta, Hydrangea paniculata, Oak leaf Hydrangea, Mayapple, Bloodroot, and Rodgesia dear to my heart. All hosta flowers are also attractive to bees. Beautiful, large white fragrant blooms on Hosta plantaginea are a fantastic bonus.

Sedum spectabile offers the longest interest in the garden, from spring until late winter .

Geranium Rozanne keeps blooming from spring until November or until hard frost.
The bulb that gives you the most bang for the buck is Allium albopilosum/cristophii. The flowerhead is stunning and stays beautiful until the wind blows it away in the fall.

I especially love rain drops on Alchemilla mollis (Lady’s mantle).

There are so many beautiful plants to choose from. You will have to experiment and find out what suits you best.

May I ask the names of the hostas in your 1st and 2nd pics in your most recent post? I'd like to know what the bright green variegated ones are. Is that Liberty in the 2nd pic?

Love them!

From June 9-10, 2014

It retains its feathery foliage in good condition until fall when it turns either a bright gold or this fiery combination.

From October, 2013

Anemone canadensis (neat foliage and really neat fall colors of red, yellow and purple..don't think I have a photo of the fall color...I'll look later and edit post if I find them), flowers for a very long period.

Both of these will go dormant if you don't keep them well-watered in hot/dry conditions.

Hi Karin_MT. Thank you. Hosta 1 is Sum and Substance. It is about 14 years old and 7 ½ ft. wide.

Hosta 2 is Regal Spendor. It is about 6 years old. From this angle, it does resemble Sagae, doesn't it? I will have to look closely again.

Hosta 3 is June. She is 3 years old. She gets afternoon sun.
I do not have Liberty. I have no more room for large hosta. :-D

Mindy - My only Hosta Sagae is mostly hidden from view. It is to the right of the largest swatch of purple in the picture just above Hosta Blue Angel. It is only 2 years old. I added 3 more shoots to the clump this year. I hope the new shoots will catch up with the rest of the clump next year.

Thank you for the suggestion. I have plenty of purple, blue, yellow, grey, chartreuse, variegated, tall spikes and everything in between, including a large variety of lilies, Allium and a large clump of Miscanthus sinensis ‘ Morning Light’ that is hidden behind the birch in the picture.

The look of my garden this year is exactly what I had imagined it would be: a perfect blend of colors, shades, shapes, textures and heights. I don’t think I want to add anything any more. In fact, I have been thinning the herd and clearing out fuzzy looking ones. But thank you just the same.
