VERVE flower

If the company in question was B & Q, Verve is the name of their own brand gardening range.
So it could be that you have a bespoke mixture of wallflowers that have been selected from the huge range available, specifically for the needs of the typical B & Q customer (ie relatively easy-care, good performer).
Given that they will have been sold at superstore prices rather than at rare-and-exclusive prices, if you don't have a use for them in your own borders or pots you could sneak them into the neighbourhood instead. Offer them to a local school, nursing home or cemetery?

One thing that might be worth mentioning - if they've been sold as Erysimum rather than Cheiranthus, they are more likely to be perennial, with a growth habit that is more shrubby than your average, standard wallflower (cheiranthus).

Agree with Teadrinker, my nearest Garden Centre is B&Q, and Verve is their own brand.

You'll notice a lot of products with Verve on them. Compost is one such product.

Hi Bamboo, Cheiranthus is now included in the genus Erysimum, but are listed as a species, but I agree they are more likely to be the perennial species, Derek.

Yea, you're right, Derekm, but for some reason, the garden centres still label wallflowers as cheiranthus and other ones, like Erysimum Bowles Mauve, as Erysimum, so there does seem to be an inclination to keep erysimum for the perennial ones.
