Hi, Trefor,
I used various Bristish wildlife books to get an idea of what's needed for the Hebrides and my wife, a keen gardener, advised me on the sorts of plants. In no particular order there are;
Rowan trees; bent by the wind. They're bits of dead heather with extra wire branches and leaves from an Ash leaf paper punch, the type you get in card making shops. Either as the seven-leaf variety from the punch or cut down, it can be used for all sorts of plants. I have a few punches now for all sorts of other leaves. Incidentally, I paint/mottle a sheet of green paper and punch leaves from this to get various shades on leaves.
Wild roses; you get tight little buds from material shops and the leaves are the same as the Rowans only five per spray rather than seven.
Gorse; Sea Foam with HO type grass fibre (Steugras?)glued on anyhow with dilute PVA glue. The idea came from a recent issue of Narrow Gauge and Industrail Railway Modelling.
Bog myrtle; Orange blobs on thin wire with two-leaf clusters on the stems.
Dried out long grass; bits of teddy bear fur. Actually an offcut stuck to a Father's day card from a daughter, meant to be a joke toupee!
Heather; something sold as "Synthetic Wire Wool". It's green and you can tease it apart. Lightly covered with suitable coloured scatter material from a card making shop.
Wild flowers; work in progress. I found a whole strip of little six pettled flowers in an art shop. These have a wire stem and leaves from another punch. I also have a book on modelling dolls house gardens. Although dealing with 1/12th
scale it is useful for G.
Ferns; from another paper punch.
Hope this helps
