Smooth stalked meadow grass seed is not widely used in the UK for lawn and landscaping mixtures. The main reason is that for our climate a blend of perennial ryegrass and red fescue will meet the needs of most situations. Smooth stalked meadow grass is also a vey small seed, around three times smaller that normal fescue or perennial ryegrass. If it is sown in a mixture with perennial ryegrass it is not uncommon for the smooth stalked meadow grass to become outcompeted by the faster, more aggressive perennial ryegrass. As is the case with all other smaller seeded species, they are more expensive because they are harder to produce, which is another reason why it may not be used in as many lawn seed mixtures.
