Description

Asclepias tuberosa, affectionately called butterfly weed, bursts onto the botanical scene with the irresistible allure of a flower-shaped neon sign flashing free nectar to every winged wayfarer in search of a sip. With its vibrant clusters of orange and yellow fireworks, the bloom beckons butterflies and other pollinators.

Don't be fooled by the name weed creeping into its common moniker; this plant is no garden gatecrasher. Indeed, Asclepias tuberosa prides itself on being every gardener's dream date: astonishingly attractive, remarkably resilient, and doesn't mind if you forget to call (or water) regularly.

Butterfly weed turns any patch into a zoological tapestry, teeming with nature's busiest pollinators—who knew conservation could be so effortlessly stylish? Whether you're aiming to spark up a monarch butterfly romance or just turn your garden into the it-spot for the six-legged set, Asclepias tuberosa hits the sweet spot, outshining its floral companions like a sunbeam in sequins.

Bring a warm, zingy summer glow to the garden with the frothy orange blooms of Asclepias tuberosa. Commonly named butterfly weed, the flat-topped clusters of nectar-rich flowers are frequented by pollinators of all kinds. The lava tone makes this a fittingly fiery addition to any hot-themed planting scheme, or they can create an eye-popping contrast with neighbouring plants with purple or blue blooms. You’ll enjoy an impressively long and vibrant flowering period which lasts from midsummer to autumn, and then further interest as flowering is followed by curious pointed seedpods which burst with fluffy seeds!

The stems of Asclepias tuberosa are fairly tall, reaching 75-90cm, and they also have a long vase life. Both features make this a favourite with florists, but wear gloves when handling as this plant can be irritant. These resilient perennials can tolerate winter temperatures down to -10°C and will grow back each year with minimal fuss, each time they will grow from a more established clump. Butterfly weed is well suited for growing in sunny borders with free draining soil and also patio containers.

The seeds of Asclepias tuberosa are equipped with silky hairs that allow them to be carried away by the wind. This mode of dispersal helps the plant to colonize new areas.

Useful information

    • Soak your Asclepias tuberosa roots in water for 3-6 hours prior to planting.

    • Plant your "Butterfly weed" bare roots into temporary pots with a multipurpose compost in spring and grow-on in a sheltered spot outdoors.

    • Choose a pot which comfortably fits the bare roots. Some have a noticeable crown which should be just below the soil surface with any top growth exposed.

    • Plant out into borders or permanent containers in late spring or early summer once in full growth. Choose a position in sun or shade depending on the variety.
