Mexican Sunflower


By Motinot

down, Ireland Ie

I planted seed of Tithonia rotundifolia 'torch' earlier in the season without much success..Only one of the plants survived, so rather than loose it, i potted it up and it has been growing away happily but did not flower.....My question is...can i over-winter this plant and grow it on next year?....It is very healthy...but no flowers...:<(




Hi Motinot - I don't know the answer but wanted to leave a comment so that i can keep up with this one as I want to grow this plant! :-)

Ok Sid....I saw it in full flower last summer on Gardeners World and i loved it....I sent for the seed...planted some in-doors in seed compost and some in success, just the one in the pic...I still have about 10 seed treating them like 'gold dust'

Well Motinot, I've read that they can be overwintered in a heated greenhouse if it has sufficent light. It is susceptible to powdery mildew if I grow it in too much shade in the garden so I doubt you can overwinter it in a house, unless you have excellent lighting in there. ( fluorescent grow lights ). I would give it a try either way though,you never know. ! If it dies, I'll have a million seeds if you'd like to try it again. There's also a dwarf variety called 'Fiesta Del Sol' that may be better suited for you to grow in pots, that only gets about 30 inches tall when it starts to bloom. instead of 6 ft tall like the 'torch". Will have to look and see if I still have any of those seeds left, if I do they are getting pretty old but may still germinate.

Oh thanks Flcrazy for your help...I'll try to over-winter it and see what happens....You are probably right about the height, 6' is a bit tall for my little garden....I didnt know there was a smaller one...If you have seeds to spare i would love some.....thank you again Flcrazy....:>)
