Ribwort Plantain (Plantago lanceolata), a perennial of grasslands and disturbed ground. In fact I notice that its niche in the garden and on the allotment is where the cultivated bed meets the edge of the grass. Its presence in fossil pollen records of the Neolithic Period suggests that it is an indicator plant of the spread and development of agriculture. Frequently described as a weed but I shall not dignify that assertion with a response.
 NB The longer spikes look more like Greater Plantain (Plantago major) which grows in similar spots. Will have to look more closely next time I'm out- are both growing alongside each other?

 Postscript 1/06/20 Ok, I'm confused. Ribwort Plantain has narrow spear shaped leaves and compact flower heads. Greater Plantain has oval shaped leaves and long flower spikes. This Plantain has spear shaped leaves but long flower spikes. Will the real Plantain please stand up?
