Product as described, pleased with seeds.


Planted and are now sprouting


I grow these every year from Marshalls because they have proved to be the most suitable for my soil and location - north Wales coast. Excellent keepers and eat very well with a good flavour. I sowed this years crop under glass on the 9th Feb and as I write they have germinated well and beginning to straighten. Will soon need transplanting. They hardly, if ever, bolted unlike sets.
