The Biogeography of the Irish Potato Famine

Bloomcore, also known as flowercore, is an aesthetic trend that is just right for gardeners. It embraces the natural world, and most importantly, flowers. Putting nature first, it creates a pretty, flowery look both indoors and outside in the garden.

Like honeybees, bumblebees visit flowers to collect pollen and nectar to take back to their colonies to feed the developing brood.

My Rhododendrons were in full bloom when a late frost caught them quite badly. Winter has been wet and mild but if the USA is anything to go by hard frosts may still be on the way so look after your early flowering Rhododendrons.

Potato blight, also called late blight, is a destructive fungal disease that is caused by spores of Phytophthora infestans. Potato blight spores are spread on the wind and may also contaminate potato tubers in the soil. It can ruin a crop in 10-14 days and there is little that can be done to save an infected crop. It was the original cause of the Irish Potato Famine.

No other plant native to South Carolina has such fragrant and beautiful spring blooms and stunning fall color as the witch-alders. Fothergilla was named after Dr. John Fothergill, an English physician and gardener who funded the travels of John Bartram through the Carolinas in the 1700’s. These beautiful shrubs have been planted in both American and English gardens for over 200 years, including gardens of George Washington and Thomas Jefferson.

This North American native plant is a relative of the popular holiday poinsettia. Both plants are members of the euphorbia family. This plant is sometimes grown for the colorful green and orange bracts, but it is considered a weed.

Quick backstory: You may remember Charley, co-author of my most-used field guide “Tracks and Sign of Insects and Other Invertebrates,” from our recent interview about galls and leaf mines, two of his specialties.(I’m giving away two more copies; enter by commenting in the form way down at the bottom of this page, after reading the entry details in the tinted box just before that. The book can help you to know what you are seeing when you look closer, too—kind of like always having Charley by your side.)When that story ran, Charley had noticed a photo I used to accompany it–of a squiggly “leaf mine” I’d observed in my Asian-native big-leaved perennial called Petasites. He’d wondered if it was caused by the insect that feeds in a few different genera in the tribe Senecioneae (including some native American botanical cousins of Petasites).  Why don’t you come try to find out, I’d suggested—and while you’re here, why don’t we have a

The numbers on a fertilizer bag are the so-called N-P-K ratio, the percent of nitrogen, phosphorus, and potash (or potassium, chemical symbol K) inside the bag. Simply speaking, nitrogen is for green growth; phosphorus is for roots, flowers, and fruit; potash is for general vigor and disease resistance. A so-called balanced fertilizer, often recommended in books, is one that has equal percentages of each element.With chemical fertilizers, the numbers are much higher than with organic formulations. A standard is 10-10-10 or 5-10-5, meaning there are those percentages of each element in the bag (the rest is filler). You won’t find those totals in any organic formulation. In fact, if the total of the three numbers on a so-called organic or natural bag adds up to more than 15, I’m suspicious. Unless blood meal—an organic material very high i

YES, YES, I KNOW: I have already told you I love hellebores. While waiting for mine to reach full bloom, I took an online tour this very cold morning of other hellebore plantings that are enviably farther along.
