Take an Online Course
If you have free time over the holidays, consider taking an online course. NGA offers two short online courses: "Perennials" and "Vegetables and Annual Flowers." For the more adventurous, we also offer the in-depth "Exploring the Garden." This two-part course explains the principles of botany in the context of the garden. If you've wondered why you need to isolate your corn varieties but not your tomatoes, or why most gardeners avoid planting seeds saved from hybrids, this course is for you. The courses can be purchased through the NGA Garden Shop. Or, you can become an NGA Supporter for just $24.95 and get access to all the courses!

Golden Threadleaf False Cypress
The golden threadleaf false cypress (Chamaecyparis pisifera filifera) I planted along a stone wall was attractive in summer, but it's especially lovely now that more flamboyant plants have faded. Also known as Sawara cypress, the shrub boasts unique texture and color with its finely cut, yellow-chartreuse foliage that calls to mind a bad-hair day. There are at least two yellow-leaved varieties: 'Sungold' and 'Aurea'. Unfortunately, I don't know which one I have.
