Monty Don showed these lemon wallflowers on gardeners world on 27.4.2012 they were planted with white and lemon tulips. Can anyone tell me where to buy the plants or the seeds.
I bought a yellow one from B&Q a few years back-in fact cuttings taken from it are flowering now-whether they still stock it I don't know but if you have one near??
Have you tried local plant nurserys ,garden centres?
