Many animals within the park rely on specific types of plants as their sole food source. Monarch butterflies, for example, only lay their eggs on milkweed, and only eat milkweed while in their caterpillar phase. Milkweed requires a moderately acidic soil to grow, surviving in soil pH levels from 4.8 to 6.8.As with most other plants, it cannot tolerate pH levels below 4. Overly-acidic soil prevents roots from being able to absorb water and nutrients crucial for survival.ilkweed requires a moderately acidic soil to grow, surviving in soil pH levels from 4.8 to 6.8.

There are 21 native milkweed species in Florida and eight native species in south Florida (see sidebar). While some of these species may not be quite as showy as A. curassavica, they work perfectly well as monarch attractants.or example, while butterflyweed (A. tuberosa) has tougher leaves than scarlet milkweed (and in fact monarchs need to eat more of this plant than other species to get the nutrients they need), caterpillars that eat only A. tuberosa grow just as well as those that eat other species including A. curassavica.
