Following an email advertising Asclepias, I spent half an hour placing an order. I ordered 3 POTS of 2L/3L Asclepias tuberosa, but I received 2 pots (?!), each containing a puny, struggling young plant. I then contacted customer service. I was told it was impossible to deliver them to me and was offered a credit or a refund. So I requested (and received the refund), but I would have much preferred to be delivered the three pots of Asclepias tuberosa 2L/3L!!! There's no point in sending emails to promote a plant if you don't have it in stock!

Description
Asclepias tuberosa is a hardy tuberous perennial sought after for its exotic appearance and ease of cultivation. Its vermilion-orange star-shaped flowers arranged in umbels appear from the beginning of summer. In late winter, the fruits ripen and release seeds with numerous silvery and shiny bristles resembling a ball of cotton.
Its large elliptical blue-green leaves are evergreen in its native habitat, but may disappear in harsh winters. The leaves are spirally arranged along the stems, forming an upright clump 60 to 80 cm (24 to 32 in) tall with a spread of 50 cm (20 in).
Native to the southeastern United States, Asclepias tuberosa is widespread in dry American prairies and is easily cultivated. It is indifferent to soil type but prefers humus-rich, well-drained soil in a sunny location. It will find its place in sunny rock gardens or dry soil beds alongside rock garden plants or Irises.
With its nectar-rich flowers, Asclepias tuberosa attracts numerous insects, especially butterflies, which have earned it the nickname "Butterfly Weed".

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).
