Orchids in our garden

Soon after we moved here we found some orchid plants appearing in our lawn. These turned out to be five Common Spotted Orchids (Dactylorhiza fuchsii) and one Greater Butterfly Orchid (Platanthera chlorantha). We were very excited to have such beautiful "weeds," and stopped cutting our lawn in the summer in an attempt to encourage them.

The numbers always rose each year, but slowly at first. Then, after 5 years, the numbers started rising much faster. That year (2002) we had 57 Common Spotted Orchids, though only 2 Greater Butterfly Orchids. We assume that it takes a little longer for the Butterfly Orchids to mature from seed as the number did not begin to increase until 2006 when we had 5.

This year the number of Common Spotted Orchids has risen to 594, though strangely 115 of these are growing in our alpine tubs, having seeded themselves there and not planted by me. As you can see, there has also been rather a large increase in the number of buttercups!

Meanwhile the number of Butterfly Orchids in flower has risen to 11, with a number of non-flowering plants also present.

In 2006 I was clearing some wood at the side of our house when I discovered that I had broken off two spikes of Broad-leaved Helleborine (Epipactis helleborine) which I hadn't noticed. Fortunately they reappeared the next year and have had 4 flowering spikes every year since then.

Asphodels

Someone has asked me about the difference between the Scottish Asphodel and the Bog Asphodel.

The Scottish Asphodel - Tofieldia pusilla - is a rather small plant with greenish-white flowers. In the UK, it is restricted almost entirely to high ground in Scotland.


Bog Asphodel - Narthecium ossifragum - is a much taller plant with yellow flowers, and is also much more common. It is found at all altitudes throughout Scotland, Wales and Northern Ireland and in the west of England.

The Latin name Narthecium ossifragum reflects the belief (incorrect) that sheep would become brittle-boned after feeding on it.

Both species are members of the Lily family and have long narrow basal leaves which are flattened into one plane.

Ben Lawers

A few weeks ago I went for a hill-walk up Ben Lawers. That time I went to the summit, but yesterday I went back with a guide from the National Trust for Scotland to see some of the rare plants that grow on the hill. These included some that I had never seen before in Britain and which are found in very few other places. The following are some of the rarest. Their names are followed by the number of 10km squares in which they are found in the UK.

All the photos were taken on Ben Lawers.

Alpine Gentian - Gentiana nivalis (3)
This tiny gentian opens only when it is sunny, so we were very lucky to see it.


Mountain Sandwort - Minuartia rubella (5)


Alpine Forget-me-not - Myosotis alpestris (5)


Alpine Fleabane - Erigeron borealis (6)


Rock Speedwell - Veronica fruticans (16) - see pictures from another location

Net-leaved Willow - Salix reticulata (17)


Cyphel - Minuartia sedoides (41)
This photo was taken on my previous visit to Ben Lawers.


Alpine Mouse-ear - Cerastium alpinum (46) - see picture from Ben Lawers

We were also lucky enough to spot a ring ouzel carrying food for its young.
