I just entered bulb in Google images and came up with some really cool and helpful pics. Have a look at this.
Bulbs direct and a couple of other local bulb suppliers have some great tips on growing and planting bulbs. Which are well worthe a look. http://www.bulbsdirect.com.au/
Now I dont know about you but something i often stuff up is the depth of planting bulbs so this is really very helpful, kind of neat. The flowers in spring are something i always look forward to so I am happy to take any advice available.
