Monarch butterflies are becoming more and more scarce , and it ’s up to humans to assist them . In the past 30 years , the issue of monarchs has minify by 90 % , as has the number of milkweed plants ( Asclepiasspp . and cvs . , Zones 3–9 ) . Milkweed is the only germ of food for the monarch caterpillar . The declination in milkweed is mostly due to increase economic consumption of pesticides , which touch the figure of pollinators , and also conditions and deforestation .

Although aboriginal , vulgar milkweed ( A. syriaca , Zones 3–9 ) can be spring up quite sharply in the Southwest , which is why milkweeds can have a uncollectible rap here , but there are over a hundred milkweed mintage native to the United States . Milkweeds are recurrent and have a diverse range of stature , color , and soil preferences , although most favour full Dominicus .
