'Weeds are flowers too, once you get to know them'

If Wordsworth had written:

'I wandered lonely as a cloud
That floats on high o'er hills and vales
When all at once I saw a crowd
A host, of golden buttercups' &c. &c. viz.

Would Buttercups still be considered Weeds?

But people already know about Dandelions viz.

and they are still regarded as Weeds.

So what chance do the following (all seen today) have?

Common Chickweed viz.

Common Field-Speedwell viz.

Cleavers (no flowers but we think the leaves to be Exquisite) viz.

Ivy-Leaved Speedwell viz.

Red Dead-Nettle viz.

Shepherd's-Purse viz.

and Thale Cress viz.
