You can find a Venus fly trap in Vermont in Walmart or in Home Depot. These plants are not found in Vermont forests and are most common in the marshes of the Carolinas.
Light affects the growth of plants just like the sun affects the growth of humans. Too little and the plant would die from the lack of gas exchange and the sunlight that it needs to grow. But to much can be harmful to, causing the plant to wilt and die if it doesn't get the amount of water that it needs to survive. The sun is the major part of the plants life, by being the MAIN part of photosynthesis.
Grevillea johnsonnii from New South Wales in Australia needs a Mediterranean type climate to grow well.So in those areas it can tolerate full sun to light shade and frost.Never use fertilizers containing phosphorus as they-and many other Australian natives- are sensitive to it .It needs well-drained soil and prune to maintain a good shape.
In a temperate climate you would cut it down by about two-thirds and transplant it in the autumn.
If you live in the northern range for hydrangeas, they need extra protection in the winter from freezing and dehydration. (I live in CT, and couldn't get blooms until I began wrapping mine.) There are many ways to do this, but this is what works for me. In the fall, spray branches with an anti-desiccant. I use "Wilt-pruf" or "Wilt Stop". Tie the branches up gently with twine, to keep plant compact. Pound 4 stakes as tall as the plant in a square shape around it, leaving a few inches of clearance. Staples burlap to the 4 stakes. GENTLY fill the "cube" with mulch or dead leaves -- it's easy to break branches inadvertently. In spring after a spell of warm weather, gently unwrap the hydrangea. Be sure the whole cube has thawed all the way through, (this takes much more warm weather than you'd think) -- otherwise the frozen blob will tip over from the unsupported water weight and, again, break branches. Carefully remove the mulch or leaves and untie the branches. You should see lots of green buds at the branch ends -- these will be flowers. The buds break off really easily, too.
