Marigold varieties readily hybridize by way of insect pollination. Whereas flower colour can affect pollinator attraction, the first issue figuring out profitable cross-pollination between marigolds in Texas is their species and, extra particularly, their compatibility inside the Tagetes genus. As an example, French marigolds (Tagetes patula) will readily cross-pollinate with different French marigolds, no matter colour, however are much less prone to cross-pollinate with African marigolds (Tagetes erecta). Proximity additionally performs a task, with nearer proximity growing the prospect of cross-pollination. Subsequently, planting totally different varieties in shut proximity will encourage hybridization, probably leading to new colour variations and traits in subsequent generations.
Controlling cross-pollination is essential for seed saving and sustaining varietal purity. Gardeners aiming to protect particular marigold traits ought to isolate totally different varieties by distance or make use of bodily obstacles like netting. Conversely, open pollination can result in thrilling new hybrids, contributing to the variety of marigolds in a backyard. The nice and cozy local weather and lengthy rising season of Texas present ideally suited situations for marigold seed manufacturing, making it an appropriate location for intentional hybridization. Traditionally, open pollination has been a significant driver in marigold diversification, ensuing within the big selection of colours and kinds out there at this time.
