If asked, most of us could probably name at least five herbs. Those used in cooking, like basil and thyme...
Once upon a time, I found herb gardening a topic of mystique and mystery. Maybe it was the herb gardening books I found, with their illustrations of medieval knot gardens, and the cute little pots of culinary herbs grown on the wide, sunny windowsill of someone’s gourmet kitchen. Or maybe it was learning that many herbs prefer a Mediterranean climate with dry, rocky soil and lots of sunshine. How could I replicate that in Virginia? It may have been...

Why container gardening with native keystone perennials, of course! Why Keystone Plants? Keystone plants are the “powerhouses” of native plants. While all native plants are beneficial, keystone plants are the linchpins for entire ecosystems, providing crucial resources for the greatest number of insect species. These keystone plants...
Q. How do I care for a Christmas cactus so that it blooms well for Christmas? A. Christmas cactus, Schlumbergera x buckleyi, is native to tropical rain forests. It should be planted in a soil mix that is high in organic material but drains well. It likes to be root bound, so don’t feel you have to keep putting it in a larger pot each year. Keep the soil moist from spring through summer but let the soil dry out...

Plants require water and nutrients for strong growth an abundant flowers. A hanging basket is an extreme environment for many plants. Baskets will dry out quickly on a scorching, sunny summer...
Picnics with citronella candles, lemon scented furniture polish and sweet tea with lemons all recall happy childhood memories. Fragrance has a profound ability to create or shift a mood, to trigger memories and create new ones. Just as cinnamon evokes the holidays; crisp, cool lemon is a summertime fragrance. Most lemon scented plants thrive in warm climates. Lemon trees, Citrus limon, are hardy only to Zone 8. Originally native to Asia, they spread throughout the ancient world wherever the...
A friend was excited to buy milkweed plants at a WBG plant sale several years ago. They aren’t easy to find commercially, and few people raise them from seed. When I saw her again a few weeks later, I inquired about how her plants were doing. “Oh, I must have done something wrong. They’re not looking so good. Most of the leaves have disappeared,” she replied. I quickly reassured her that it was unlikely she had done...

And most importantly, will it go the distance and survive all season?...
