Create a serene winter-holiday tableau with this simple arrangement: birch bark wrapped around glass cylinders filled with plants found easily at this time of year. Trimmings from the holiday tree and scented geranium leaves snipped from a house plant accentuate the amaryllis blooms.

Bouquets of bold-red amaryllis tied with stiff silver ribbon and displayed down the center of a table look stunning against the hushed gray, white, and silver setting. The napkin rings and the beading detail on the rims of crimson and silver of the Nymphenburg porcelain plates are as simple and charming as a spray of frozen raindrops.

Massed paperwhites seem to float above the downy dusty miller leaves beneath them. The mercury-glass pots, which gleam against the silvery foliage, and the enticing fragrance of the blooms add to the enchantment.

Create an intimate woodland effect around your mantel with arching branches of fresh -- and wonderfully aromatic -- blue Atlas cedar (which you can order from greenvalleygrower.com or a florist, allowing ample time). The cedar's spiky needles contrast with the grace of its weeping form and the delicate paperwhites at the branches' base. The bluish cast of the branches sets off touches of red, gray, and silver around the room. (To keep the branches from drying out, add water daily as you would to a Christmas tree.)

Red-and-white amaryllis recall classic candy-cane stripes and thus inspired this container. Cylindrical glass vases are wrapped in pearlescent paper or vellum and finished with red ribbon. Pure red amaryllis anchor the grouping, and dishes of peppermint candies set off the display.

The holidays may be over, but the memories are still fresh -- and so is much of the decorative greenery. Keep the festive feel alive: Mix cut flowers with leftover evergreens -- in this case, yellow spray roses and mango calla lilies with cedar sprigs.

For Valentine's Day, use this ''floating'' heart -- made with pale shades of common, easily obtainable blossoms, such as carnations, mums, and hyacinths -- to express your adoration.

On February 14, only one flower will do. It's not that a big bouquet isn't sublime, but a single genus best conveys a message of love: the rose, preferably in lush tones of red and pink.

Here's an especially pretty way to wrap up your Valentine's Day gift. Four dozen red and pink roses stand out in this arrangement.

Flowers and candy are the touchstones of courtship and romance. But handing over a bouquet and a box of chocolates isn't the only way to show you're sweet on someone.

A valentine of any age will enjoy the fun messages that this arrangement delivers. Pastel candy hearts proclaiming ''Class act'' and ''Be true'' and tulips in complementary colors, such as creamy 'Cheers,' pale-pink 'New Design,' and 'Apricot Beauty,' convey your feelings with more than words.

Inspired by the jeweled treasures crafted by Peter Carl Faberge around the turn of the 20th century, this ''easter egg'' is decorated with spring-blooming hyacinths and pearl-headed pins.

Big, round 'Lumina' pumpkins bring a ghostly glow to a dining room. Place them directly on the table or on serving stands and platters during your Halloween parties.

The jewel tones and cascading abundance of these arrangements are an ode to autumn. Set in gleaming containers, extra-big black and crimson grapes give a nod to that ubiquitous Thanksgiving motif -- the cornucopia.

In November, well-tended gardens (and well-stocked farmers' markets) are ripe with offerings. For Thanksgiving, showcase the bounty indoors with a sculptural display.
