I visted a friend's garden today where these super plants were huge with woody stems, I admired them and asked for more details. She gave me the empty seed packet which says they are hardy ANNUAL.. and to sew outdoors in April.. which is now. Yet these are fully grown. Does 'hardy' before annual mean that they stay over more than one year? I am confused. If I get some seeds and plant them now how will they manage to get so big?
They will have germinated last summer and over-wintered. They often do that, the biggest best specimens come that way
I find they seed around and move away from where you first put them. At the moment mine are in the gravel drive, having started in a bed. I forgive their waywardness.
Cerinthe are very easy plants to grow..........the will self seed happily.......particularly in a mild winter. I have several which are flowering now........the largest about half a metre tall ..........a seedling from last year. The Bees love them....well worth growing
Everything seeds in a gravel drive, I'm going to try and remove a couple of Clematis recta seedlings tomorrow, then I might have to go down the chemical route
I collected a lot of seed from my Cerinthe last year & sold it on ebay, very popular.
Don't bother buying seed, your friend will have more than enough to give away. It se;f seeds everywhere but in al the right places and looks great.
Thank you everyone - I am on the case now!
I thought that they were half-hardy perennials....Usually treated as a hardy annual?
If you bring them in over winter, they'll survive for years I thought, just like pelargoniums
These are my two sown from seed at the wrong time (last augustI think), left in cold GH and grew quickly. also had some indoors but couldn't give them enough water and lost them! These are still a bit leggy.
