In my back garden you’ll find a towering plant near eight feet in height. I didn’t know Tithonia (Tithonia diversifolia), often called Mexican Sunflower, could grow so tall. The petals open up for me in late summer and are surprisingly velvety to touch. The seeds were part of a Wildflower Mix by Botanical Interests. The plant grows in a plot of ground once prepared as a square foot garden. The amended soil, vermiculite, mushroom soil, etc., must still have some ‘POW’ remaining; the plants within the confines grew much larger than average.
The size the plant reached in one season amazes me. Unfortunately, Tithonia is an annual and won’t survive my southern NJ winter. I saved mature/ripened seeds and will replant in Spring. The ground hasn’t frozen yet and is still soft and workable; this week, in addition to the seeds I saved, I will also scatter a few Tithonia seeds throughout my garden beds in hopes they will grow when warm weather returns. Seeds overwintered in the earth always grow best.
The flowers blossom at the end of a long stem, perfect additions to floral arrangements. The stems remain sturdy in a vase, the flowers, if picked at peak bloom, stay fresh and lovely for over a week. The stems can be cut short or tall for height.
Requirements for growing Tithonia:
*7-10 days for germination
*Sun for most of the day
*Needs at least three feet of spread room
Will I grow Tithonia again. Oh yes…I am saving many of the seeds and intend to leave the remainder for the birds to nibble through the winter. I will leave the plant in place instead of cutting away. The branches and any leaves that stay on the plant will provide shelter for the birds and also give them a chance to land and check for predators in the area around the bird feeders.
