This is the original blue form of the highly unusual Tree Echium. A hardy biennial that grows a large rosette of silver-grey leaves in the first year, and a very tall flower spike of blue flowers up to 4.m high in the second or third year. Plants generally flower from June to September. Each spike is made up of masses of tiny blue flowers that attract lots of pollinators.
These are very striking and impressive plants, but tend to be on the tender side, so they need a nice warm, sheltered, open and sunny position for flowering, and the rosette may need protection in a greenhouse in the first winter. They grow and self-seed outside in the warmer parts of the UK, such as here in Cornwall, in sheltered coastal sites.
Pack of 20 seeds. Sow in spring/summer for flowering the next year. Sowing instructions and a colour photo are printed on the packet.
Some parts of the plant are considered toxic.
