If you are looking for a tall dazzler then Tithonia rotundifolia might be for you. This orange whopper grows to a height of about 6ft (1.8m) and towers over other plants. it tends to topple over in high winds so it’s a good idea to stake the plants.
It can be grown as a perennial but in the UK it is mainly grown as an annual.
Tithonia rotundifolia likes to be well drained but the soil needs only to be poor to average for the plant to do well. It’s best not to plant them in a particularly rich or heavy clay soil. It is best not to fertilise the plants as this tends to only increase foliage growth to the detriment of flower production.
Tithonia rotundifolia prefer to be positioned in full sun.
The flowers appear in mid summer and can continue until the first frosts. In cool or dull and wet summers then Tithonia rotundifolia might not flower.
Plants grown from seed should be only put out when all risk of frosts has gone
