Actually, the first 10 photos are from recent trips to two conservatories: Hidden Gardens near Tecumseh, MI and Meijer Gardens in Grand Rapids.
Conservatories have a mixture of the opportunity to take pictures of plant life not common to your area (saving by not traveling to the tropics) and some challenges. The muted lighting in conservatories sometimes may require a flash to get the effect you want. You may also need to work hard to get a suitable background for your image.
The pictures that follow (except for the last one) were taken using an 18-55 zoom lens.
