Originally from Brazil, these flowers are prized for their small, five-petaled star-shaped blooms, which range from intense glacier blue to bright sky blue to clear pale blue – colors not often found in commercially grown cut flowers, at least not naturally (dyed blue flowers are fairly common). The blue-flowered varieties will age to purple. Although they are more rare, there are also white and pink-flowered varieties.
Tweedia requires a warm, dry climate to thrive. Unfortunately they can’t be grown as a perennial here in Alberta. However, they are wonderful cut flowers for bouquets. Definitely worth seeking out at a local flower shop!
If you are lucky enough to live in USA hardy zones 8A or higher, they make a beautiful addition to your garden. They will grow 2-3 ft tall. If you wind them around a trellis, they can reach up to 10ft in height. They will self sow and can overtake your garden. As such, it is recommended to cut them back each fall and remove the seed pods.
Tweedia is a member of the Asclepiadaceae, or milkweed family, which includes Stephanotis, Hoya and Ceropegia.
Tweedias are a noteworthy choice for brides and grooms who desire “something blue” in their wedding flowers or boutonniere. They are excellent for hand-tied bouquets as well as ideal for garden-style or “wildflower” arrangements.
