Tweedia caerulea
Tweedia caerulea

Tweedia’s sky-blue flowers are tiny, but they’ll stop you in your tracks. Clear blue flowers are so rarely seen in the garden that these dainty beauties take center stage on many garden tours. Also known as blue milkweed, tweedia is native to South America and a member of the milkweed family. It attracts pollinators and makes a striking cut flower. Grow it in a container or in the garden. Be sure to place it near the front of a border or near a path where you can admire the daisy-like flowers up close.

Grow Your Own Bouquet

Fragrant blue flowers combined with velvety-soft gray foliage make tweedia a favorite for a bouquet. Plant a handful of other annuals and perennials that boast great flowers and foliage and you'll be able to create your own bouquets right outside your door. Aim to create a cutting flower plant palette that blooms from spring through fall.

Here's a quick list to get you started. For spring bouquets plant daffodils, peonies, and small lilac shrubs. Summer cutting flowers include tweedia, purple coneflower, lavender, sunflower, black-eyed Susan, and zinnia. Create beautiful fall bouquets with ornamental grasses, turtlehead, sedum, caryopteris, and dahlias.

Tweedia Care Must-Knows

Tweedia grows best in full sun and moist, well-drained soil. A tropical plant, it is hardy in Zones 10 and 11 where it is grown as a twining vine or small shrub. Grow it as an annual plant in all other Zones. When choosing a planting location for tweedia, search for a place that is protected from strong wind. The delicate flowers are easily damaged in heavy gusts and intense rain. A sunny, sheltered corner of a patio or the south or west side of an evergreen shrub often provides excellent shelter for delicate plants.

Tweedia grows well in containers, raised beds, and in the ground. Start seeds indoors 6 to 8 weeks before the last predicted frost in your area. Provide this short, vining plant support at planting time by placing it at the base of a trellis or teepee. Since it grows only 1  to 3 feet tall, it can benefit from small branches sunk into the ground alongside the plant as extra support. Tweedia can be overwintered indoors. Bring containers indoors in fall before frost and place them in a bright, cool spot.

Plant Tweedia With:

You can depend on this cottage-garden favorite to fill your garden with color all season long. The simple, daisylike flowers appear in cheery shades on tall stems that are great for cutting. The lacy foliage makes a great backdrop for shorter plants, as well. Cosmos often self-seeds in the garden, so you may only have to plant it once, though the colors can appear muddy or odd in the reseeders.Plant cosmos from seed directly in the ground in spring. Or start from established seedlings. This flower doesn't like fertilizing or conditions that are too rich, which causes the foliage to be large and lush but with fewer blooms. It does best with average moisture but will tolerate drought.

Nasturtiums are so versatile. They grow easily from seed sown directly in your garden's poorest soil and blooms all season until frost and are never greedy about food or fertilizer. Nasturtiums are available in either spreading or climbing types.Plant spreading types in large containers to spill over the sides. Plant them alongside wide paths to soften the sides for a romantic look. Use nasturtium to brighten a rock garden or between paving stones. Plant them at the edges of beds and borders to fill in between other plants and add soft, flowing color. Train climbing types up trellises or alongside fences. The leaves and flowers are edible; use them as a showy plate garnish or to jazz up salads.
