Does anyone use excel to catalog their collection? How do you keep track of it all?

Hey everyone!

I am starting an excel file to keep track of all my plant children. I have the orchids separated by genera, and then I have several categories following to fill out for each plant:
-nickname
-date acquired
-date of last bloom
-bloom duration
-bloom season (sp, su, fa, wi)
-# flowers in last bloom
-# spikes last bloom
-date of last repotting
-who gave it to me/where I obtained it
-cost of the plant

and I am continuing on down with as many little data points as I can think of.
How do you keep track of your large collections (because I'm sure most of you have more than my paltry 23 plants, haha!). Are any of you nerdy enough to do it this way?
Do you keep library cards in boxes? Do you use the dewey decimal system? Do you keep track of it all mentally?

What other categories do you think I should add to help remind me about each plant I have?
I want to keep it all in excel so I don't have to think of it and so I don't forget!

Thanks, guys!
