Sow sunflower seeds individually in 7.5cm (3") pots of a good compost from February to April. Place in a propagator at a temperature of 18-21C (64-70F) or seal the seed tray inside a polythene bag until after germination, which usually takes 7-21 days. Keep the surface of the compost moist but not waterlogged and do not exclude light, as this helps germination.

After germination, grow sunflower plants on in cooler conditions before moving to a cold frame outdoors. When they are well grown and all risk of frost has passed, plant sunflowers at a distance of 60cm (24") apart in a sunny, sheltered position on moist, well drained soil.

Feed and water sunflower plants regularly. Stake sunflower stems with tall canes to prevent wind damage. Maximilian Sunflowers are perennial - cut the stems back in autumn to make way for new growth the following spring.

  1. Seductive Sunflower

    By Steven Turner 29-10-2016

    With sunflowers being one of those flowers that always bring a smile to my face, the thought of perennial sunflowers seems a dream come true. These plants have performed above all of my expectations. Growing to 8ft in the first year, late flowering providing much needed colour in late autumn. The fragrance these flowers give out just keeps you going back for more, like smooth silky chocolate that melts in the mouth and takes you to a little bit of paradise. If there is one plant to make space for then this is one of those.


    Thank you very much for your glowing review. I am glad that you have been happy with your sunflower purchase. I hope we can continue to be of service to you in the future.

  2. Maximillian. An inspiring project

    By Dinah Dayus 24-03-2015

    As a child I loved sunflowers, but was a bit sad to see them die in autumn. I'm growing them this year for a friend's lad. He's not interested in growing the biggest, but wants them to attract bees, and to leave the seed for the birds in winter. He loved the idea of growing perennial ones. I can't think of a better way for a child to remember his early interest in nature than to plant some of these in “the year of the sunflower.” I first grew Maximilian two years ago for a charity fête. People were surprised to learn it was perennial – and very eager to own one. Reports coming back prove it's a great variety; easy to grow, keen to flower, and everyone comments on the delicious smell!
