Plant Information Online
If you know a plant's common or scientific name and want more information, Plant Information Online is an excellent resource. Type in the name, then click one of three options -- Plant and Seed Sources; Book and Magazine Citations to Plant Info and Images; Selected Links to Plant Info and Images -- for more. There's also a box for Nursery Information, but I didn't find anything for the PA/NJ nurseries I typed. Plant Information Online taps into sources in 1081 North American nurseries for 108464 plants, has 379337 citations to 142530 plants in science and garden literature, links to selected websites for images and regional information about 13599 plants, and accesses information on 2540 North American seed and nursery firms. Plant Information Online is a free service of the University of Minnesota Libraries.
Favorite or New Plant
The daisy-like calendula, aka pot marigold (Calendula officinalis) is a cool-season favorite. The yellow to orange flowers have edible petals that bring a late spring, early summer flourish to all sorts of salads, rice, and fish dishes. I've found calendula seeds to be dependable germinators and the seedlings strong growers. Calendula is said to have medicinal powers. Though I can't attest to that, I am thoroughly enjoying the light, delicately scented calendula hand cream I bought in a Budapest grocery store.
