Celandine poppies bloom in spring

I have a shade garden and would love to have celandine poppies. What’s the best way to grow them?

Celandine poppyCelandine poppies, or wood poppies, (Stylophorum diphyllum) are among the prettiest flowers in a shady woodland garden in early spring. Tall stems with bright yellow flowers grow from clumps of lobed leaves in late March, April and May, before developing fuzzy seedpods. This native wildflower grows well in moist, slightly acid humus-rich soil.

When conditions are right, Celandine poppies grow and spread easily. Nashville wildflower expert Margie Hunter, in her book Gardening with the Native Plants of Tennessee, notes that they “readily self-sow” (other sources describe this as becoming “weedy”).  “If germination gets out of hand, just snip off the large seedpods before they open,” Hunter writes.

Consequently, they are also easy to share. Divide them in spring, or start them from seeds in a cold frame in the fall.

In today’s Tennessean: Sage, thyme and lavender are just a few of the herbs that can look as good in the landscape as they taste in the kitchen. See the story on double-duty herbs in today’s Tennessean and at Tennessean.com.

April is also a great time to get out and meet other gardeners. Check out the Events calendar at left, and in my newspaper column at Tennessean.com.

Daffodil dreams? Time to plant bulbs

I love daffodils! We are planning our first garden in our new house and want to plant bulbs to come up next spring. When is the right time to plant?

Daffodils 2Fall is typical bulb-planting time, and the cooler it is, the better, according to daffodil experts. Anne Owen of the Middle Tennessee Daffodil Society in Nashville (Zone 7a on the USDA Plant Hardiness Zone map) says the best time is when the soil is 52 – 54 degrees (usually November in Middle Tennessee). But you can buy bulbs and begin to dream about spring daffodils, and prepare the planting areas as soon as you like.

Daffodils enjoy well-drained soil, so if your soil needs to be amended with compost, do that before you plant. “Lighten heavy clay with perlite or sand, or use a raised bed soil mix,” Owen suggests. You can work soil conditioner into the soil – anything that will create a loose growing environment for the bulbs.

Daffodils grow best in full sun. Keep in mind, though, that they grow and bloom early, while there are fewer leaves on trees that will cast shade, so even a tree-canopied space may have more sun in late winter and early spring than you realize.

If you don’t want to go to the trouble to prepare beds for the bulbs, you can simply dig holes and drop the bulbs in the ground. Choose an area where you won’t need to mow until early summer, Owen says. Daffodil foliage should be left standing for many weeks after the bloom time is over, because this is when they’re gathering strength for the bulb to bloom again next spring.

Plant large bulbs (pointed end up!) about six inches apart. Bulbs can benefit from a dose of low-nitrogen fertilizer at planting time, Owen says. Water the bed well after planting.
