oxalis triangularis and fern

Placing potted fern in the middle of two oxalis triangularatis, I dont know which should steal the show. Fern has always been exotic in nature with its beautiful leaves, but oxalis triangularis comes in colourful, with deep purple butterfly look  leaves. If we look closely there is a hint of red somewhere within purple leaves. Whitish stems and pale pinkish flowers place oxalis triangularitis within the category of being exotic too. Both plants just grow..., and they don't react too much with poor watering and fertilising.

Putting them in line, I wonder which one looks better or

they simply complement each other as a package.

The combination of strengths will complement each other 

and balance out individual weaknesses 

which will lead to overall enhancement 

of the team.
