I just joined PBS this morning and wanted to introduce myself. My name is Earl Nickel and I'm a professional nurseryman at Grand Lake Ace Garden Center in Oakland CA. As well, I write a regular column on different aspects of gardening for the San Francisco Chronicle and Pacific Horticulture magazine. I have a diverse garden that includes a great many bulbs. I have a particular interest in South African bulbs and have written articles on this subject for the above outlets. My new passion is Arisaemas. I've been thinking of joining for years and am glad for finally taking the plunge.
