Article V explains the amendment process, which is different and more difficult than the process for making laws. When two-thirds of the Senate and two-thirds of the House of Representatives vote to change the Constitution, an amendment goes to the state legislatures for a vote.
Another way to use the fridge for brief cold stratification is to plant the seeds in individual jiffy pellets and put them in either a plastic covered container (such as for home baking little bread loaves) or in a store-bought greenhouse flat. Depends on how much room you have in your fridge.
Plant root divisions (basal stem pieces with attached roots) after last frost, 2 to 3 feet apart in rows 2.5 to 3 feet apart. Planting from seed not recommended because results are highly variable and usually inferior to parent plants. But if you do, start seeds about 8 to 12 weeks before last frost. Harden off in cold frame. Cold treatment of starts (keeping temperature between 35 F and 50 F for about 10 days) can induce flowering in first-year plants. Transplant outside after soil has reached 60 F.
