Description

A friend gifted me seeds from her Pennycress, and legend has it that it has been growing in the Skagit Valley since the year I was born. The bright, clean, apple-green stems are well-branched and loaded with round, textural seedpods. As seed heads mature, they turn the color of wheat. Succession-planting is recommended as pods come on all at once. Cress is a terrific textural filler for bouquets and can be dried for autumn wreaths.

Details

Plant type: hardy annual
Height: 36 to 40 in
Site: full sun
Days to maturity: 50 to 60 days
Plant spacing: 2 to 4 in
Pinch: do not pinch

Seed Sowing & Growing Notes

Start seed indoors in trays 4 to 6 weeks before last frost; transplant out after all danger of frost has passed, or direct-seed as soon as the ground can be worked. Succession-plant every 2 weeks for continual harvest. Don’t pinch plants.

Harvesting/Vase Life

Harvest when seedpods are fully formed and the top blooms have faded. Expect a vase life of 7 to 10 days. Seed heads can be dried and used indefinitely. To dry, hang upside down in a warm, dark place until firm.

Fabulous Foliages and Fillers
Fabulous Foliages and Fillers

Having a steady supply of foliage is key to successfully making bouquets throughout the season—in spring, during the long months of summer, and into early fall. In this post, I’ll share the best staple foliages and foliage-like fillers, along with several of my favorite varieties.

Easy-to-grow Hardy Annuals

Hardy annuals are some of the hardest-working, most productive plants in the late spring/early summer cutting garden. They are the first annuals to bloom in the spring, and their ability to withstand cold temperatures, thrive with minimal care, and produce abundantly for weeks from a single sowing make them an indispensable addition to the cut flower garden.

These unique textural elements add interest and depth to any arrangement with their rustic appeal, and they produce an abundance of cutting material from midsummer through autumn. In addition, many of these materials can be dried and used in autumn wreaths and arrangements, making them doubly valuable in the cutting garden.

Many cut flower varieties can be used either fresh or dried. Drying flowers means you can preserve the abundance from your garden to be enjoyed later when nothing is blooming. There are so many ways to use dried flowers, seed pods, and grasses: in late autumn arrangements, adorning fresh holiday wreaths, or even mixed with fresh blooms.
