Sage is a shrub originally from the Mediterranean region. It has pale greyish furry leaves, and grows all year around. Is used to flavour fatty meat dishes, and as an ingredient in sausages in some countries. It is very commonly used with onions as stuffing for chicken or pork.
Salvation Jane, also known as Patterson's curse or Viper's Bugloss, was a garden plant in Europe but once introduced to Australia it became one of the worst weeds in the country. It grows to about 60cm tall and has purple flowers. It is toxic and can kill some animals like sheep and horses if they eat too much of it.
Sap is the thick, sticky fluid that is inside tree branches and stems. You can't see it until the plant is damaged in some way, like having a branch cut off or some kind of insect bores a hole into it.
Many kinds of sap are sweet and are eaten by birds and insects. People collect the sap from maple trees to make maple syrup. Latex is made from sap as well.
Snapdragons are an old-fashioned flower. The flower can be squeezed to make it open like a dragon's mouth, which is why they are called snapdragons.
They should be planted in well-drained soil in full sun. They can be planted at any time of year, and take about 8-10 weeks to flower. They come in a big range of colours, but shades of pink and white are most common.
