Sorry for the late reply, didnt had much time to be online lately. About the camera, if you only want to take photos of flowers and nature etc and you think you will keep it just as a hobby you can safely go for any good compact digital cameras, these days compact digital cameras give you good range of optical zoom, some manual options and they r small and easy to carry. The only catch is, after a while you get bored and you want more, you want to try new things, new settings, new lens options and so forth. This is when you cant change to other good lenses.
If you think after 6 months or so you would like to grow and experiment new things... than the good option will be to go for the DSLR, they will give you much more options, manual control, and later if you want, you have wide variety of lenses to choose from, even if you change your camera you will be able to use those lenses. but its unlikely you will be carrying your DSLR everywhere because of its size.
If you decide to go for DSLR, I will recommend any entry level camera from Canon or Nikon. Both brands are excellent (there are some other good brands as well) but the major reason I recommend these 2 is because many third party accessories are easily available and they are cheap, third party lenses, speedlights, wireless triggers etc. As a new photographer every 3-4 months you would want something new and branded things will be 2-3 times more expensive, so its easy to go for these 2 brands as hobbyist.
You can also wait till the mid of September, because Photokina (worlds largest photography equipment exhibition is going to be held) so many brands are announcing the new cameras and equipments, so after a month you ll have more options plus if there is a replacement of the camera you like you might get it cheaper after a month.
