Giant Echium (echium pininana)
In the Autumn/winter of 2013/2014 I sowed Echium seeds in the greenhouse and planted out into pots and directly in the garden this spring. The pot grown plants suffered a bit due to lack of watering whilst we were on holiday but survived. The plant in the garden grew very well and is now about 5 foot tall - it is in full sun in a well drained site. None of the plants flowered this year. As I sowed the seeds quite late in 2013 I'm wondering if 2014 was the first year of the biennial and if i can expect them to flower in 2015. I am aware they are tricky to grow but a present they are not behaving like a perennial on its second year. We are protecting the outside plant from frosts. Any advice would be welcome.
