I honestly don't think that any plant will support a high heel securely. And any plant will snag a heel. Even a close cropped English lawn is dodgy. And heels sink into any kind of soil. High heels need a flat solid surface to be safe.

2ft x2ft with 3in gaps would be a difficult surface for any gait and any footwear imo. Most people's stride length would make it awkward to pick their way over such a combination.

If your grass supports your heel, your groundcover might. If your grass doesn't, you are unlikely to find a groundcover that will. That said, when the ground is damp, your heel will sink. Why wear heels? They make elegant flats. I decided years ago I'm never wearing heels again.

Dwarf Mondo Grass gets really thick over time, I had it planted in heavy clay in a low spot & it got so thick that I do not believe that a high heel would have gone through it.

Even a lawn will not support a high heel....at least it won't unless it has been baking in dry heat for weeks and is more like concrete!! Neither mondo grass (much too tall) or any other groundcover I can think of - and I have used about all the popular ones in my design work - will support that sort of concentrated weight. Floral's advice is dead-on.

@floral_uk z.8/9 SW UK What size paver and spacing would better support a normal stride?

@Sigrid I am not wearing heels. I am trying to think through the worst case for someone who might walk over that patio.

@gardengal48 (PNW Z8/9) What about Silver Carpet Dymondia?

@gardengal48 (PNW Z8/9) I am talking about Dwarf Mondo Grass, it is only about 1,&1/2 inches tall, much, much shorter than standard Mondo Grass which is 6 to 8 inches tall. The dwarf variety became so dense that nothing could penetrate it.

" What about Silver Carpet Dymondia? "

Nope. Doesn't even hold up well to normal foot traffic.

For a patio intended for actual use I wouldn't have gaps at all. Hard to walk on, awkward for furniture feet and difficult to maintain.(weeds grow in the gaps). Just have a solid flat surface.

We have a similar patio with gravel between the pavers. This was part of a water mitigation project and would not have been my first choice but looks good. Yes people (and my yorkie) tend to adjust their stride to the pavers. I would not do this in a public place where people might have fancy shoes.

Solid surface only for high heels. Even a well packed surface with stuff growing in it can catch and trap a high heel. Gravel can turn under a heel. Of course, many folks are able to walk on pavers in heels without hitting the gaps between. But why risk it if you know high heeled folks are going to be walking around there- just make it all solid.

Agree!

It’s not the groundcover per se, it’s the soil or gravel or mulch. What gardengal said. Would have to have “ soil” that is hard/ baked and functioning just like a surface.

A neighbor has fake grass between large stones for the driveway. Would something like that support a high heel? I have no idea. It looks fine. You can tell it is not exactly the same as the surrounding grass up close though.
