I was very fortunate a couple of years ago when I was able to help out a community garden in our region and was gifted several plants as a thank you. One of these plants was a passion-fruit marigold - Tagetes lemmonii. Not knowing much about it at the time and assuming it was just like every other marigold, I planted it in the Potager garden.
While this plant has similar effects much like other marigolds, it also is a fabulous plant that has a more extended flowering period, from autumn right through to winter. It has beautiful yellow daisy flowers and is well known for its leaves. They possess an aroma which can be easily smelt when the wind passes over the foliage, or when the leaves are crushed. It smells like ripe passion-fruit! It is also a drought tolerant plant for a sunny position. It makes for a great addition to any permaculture garden - It is originally from Mexico, and it makes a fabulous border or informal hedge plant that is drought tolerant that thrives with the hot sun overhead and grows to approx 1.5 metres tall and 1 metre wide and is a soft-wooded perennial.
I am now actively taking cutting to strike and also asked if the community garden has more seed so that I can more of this wonderful plant to my design.
They are effective in a couple of different ways:
