e) Propagation: Has an excellent capacity to self-sow. Can also be planted directly from seed or use your hands to snap back the branches or a lopper, and spear into desired location.
f) Controlling Spread: This plant grows very quickly but it is easy to weed. Branches are so weak they can be broken off by hand. We try to keep this plant in areas that we don’t access often like the front of the property and in the front side of the crater.
g) Difficulties with this plant: The branches grow erratically in all directions, even horizontally so it should not be in any border areas where it will just grow over the border.
h) History of this Plant at Hedonisia: All the Mexican Sunflowers we have on the property started from just one potted plant!
