I came across a three-cornered leek in full flower beside a stream on Slievemore Mountain, on Achill, near the deserted village. I don't think I've ever seen one before, and this species normally flowers in March and April.

Also called three-cornered garlic, it is a garden escape and an invasive species. The biological records have it on the mainland adjacent to Achill, but it hasn’t been reported previously from the island.

We would be grateful if you could help us identify the creature in a photograph that I took last autumn.

In the last days of December we came across significant numbers of Velella and another jelly, probably Pelagia, on Gurteen beach, near Roundstone. I don't remember seeing these in midwinter before. The water does seem a bit warmer than in other years.

Strandings of both jellyfish are more usual in autumn. Their late arrival may well be due to rising ocean temperatures. There have been reports of strandings of by-the-wind sailors also from Donegal, and Kerry.

Is it unusual to have sweet peas in my garden on December 26th? They were always finished by mid-September.

We have had unusual autumn and winter weather. Enjoy.
