Plant Overview

A beautiful, if rarely-seen plant, it deserves to be more widely grown. It flowers reliably year after year, it's not pushy or invasive, is not fussy about soil or situation and is fully hardy. Photographed is the plant growing in the Oxford Botanic Gardens.

Heads of ornamental, rich blue flowers which are larger, and open for longer than most other varieties, and narrow lance shaped foliage. 

A most desirable native of Greece and Asia Minor. Good at the front of a border as single specimens or planted in groups to form a large clump.

Blue star-shaped flowers in May and June. Easy to grow and slug and snail resistant.

Named after Charles Amson, an 18th-century physician from Virginia.

Height: 50cm

Common name(s): Eastern Blue Star

Amsonias prefer moist soils, but grow well in most garden soils. Drier conditions reduce the height of the plant, but they will flower well every year. They grow in full sun or semi-shade - but in drier situations they are happiest in semi-shade.

Syn: Rhazya orientalis. 





All our plants are supplied in 9cm pots unless otherwise specified. Plants in this size pot establish quickly in the garden and often outpace plants in bigger pots planted at the same time. Our potted plants can be planted immediately, unless otherwise noted, or you can leave them in their pots until you are ready to plant.
The majority of our plants are grown outdoors. This means that they follow their natural growth patterns and are ready to plant at any time of the year. If you order the plants in winter, they are likely to be dormant and died back to ground level, ready to shoot again in spring - just like the herbaceous perennials in your own garden. Very occasionally, in winter, we may indicate on the packing slip that a plant needs to be hardened off before planting out. This will be because it has just come out of a polytunnel. If you have any questions about our plants or growing methods, please feel free to drop us an email.
We grow most of what we sell ourselves, in our nursery in the Buckinghamshire countryside. Our prices include VAT at 20%.
