Shopping for a water softener: 1  Salt-based units need to have the salt replenished on a regular basis, usually at a cost of anywhere from $2-$15 a month depending on the cost of the salt ($3-$8 per 40-pound bag) and the amount of salt used by your system.
Milkweed is the common name for perennial, herbaceous plants of genus Asclepias, family Asclepiadaceae (from Greek physician Asclepius). One hundred species occur worldwide; 13 are native to Canada.
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.
