Four-o-clocks are bushy annuals with colourful flowers and a sweet lemon or orange fragrance. They grow equally well in part shade as well as full sun. They begin flowering in midsummer when sown directly as seed, but will flower earlier if grown as transplants. The individual flowers open early in the morning and late afternoon and are also called four o clock flowers for that reason. They often will stay open until the following morning then close and die. A single plant may contain different coloured flowers depending on the mix. M. jalapa is a bushy, tuberous perennial often grown as an annual, with fragrant flowers opening in the afternoon, in a wide range of colours, and sometimes bicoloured.
I received these seeds today and am looking forward to growing them. They sound very interesting. I plan to soak a few seeds overnight with a view to sowing in modules. I was pleased to learn that they have a citrus scent too. I have sown these seeds today Wednesday 1st February and apparently they can take up to thirty days to germinate. Update – 12th March and there is one two inch seedling standing alone like a Meer cat on guard and quite a few seeds showing signs of growth. It was worth the forty day wait. 20th March I have potted on six strong seedlings. Update March 2018 – Only two of these seedlings made it into a decent plant and I potted them both on into 7″ pots. Update 2018 – I have sown another eight seeds. Im not sure that last years will come back. They are pretty flowers but overall I was disappointed. We will see what this year brings. Update September 2018 – Well no more disappointment. This year has given us three large bush like plants. One marbled colours, one beautiful, bright yellow and one delicate, pale mauve colour. These plants will be in my garden every year from now on.
Another bonus is the amount of beautiful black seeds produced on this years plants.
