I'm a daffodil collector, in a small way. When I first started my garden, I put in a couple of dozen King Alfred daffodil bulbs, the standard yellow ones. They did really well and multiplied like crazy. They still bloom first of the daffodils and started flowering a few days ago.
A few years later, someone gave me a pot of Tete-a-tete bulbs. There beauties are only a few inches high. I still wasn't doing much flower gardening back then, but I put them into the ground and they've been blooming every year since, though they haven't multiplied. They open just a day or two later than the King Alfreds, and their flower looks like a tiny copy.
The next gift I received was a few Ice Follies bulbs. Their flowers have petals of a creamy, light yellow.
Once I had three different daffodils in the garden, something happened to me. I was hooked on them and started searching out more. I'm up to 15 varieties now. (Actually, it's more than that, because I ordered a mixture once.) I think it's time to stop adding new ones and take time to enjoy the one I have for a while.
