The gas plant is an upright perennial , stout in Zones 3 - 8 , that blooms in late springtime to other summer with minor white or pinkish flowers . It does well in northern climates with cool nights and tolerates light shade . Gas plants like to be left alone to grow , and do n’t like to be disturbed once planted .

The flatulency plant can also ad libitum burst into flames on very hot , dry twenty-four hour period . In most cases , the oil burn off too speedily to damage the plant life , but surrounding flora could be harmed — especially in dry conditions .
It should also be mention that contact with the plant can cause photodermatitisin some people — a condition that is said to mimic the look and discomfort ofpoison ivy . It ’s best to wear mitt , branch coverings , and other protective gear when working virtually or manage this perennial .

Do not store the seeds any longer or they may fail to develop .
Sow the stratified seeds into a tray with a bed of moist potting mix and spit a light stratum of territory over the seeds , but do not wholly cover them . Cover the pot or tray with credit card wrap to create a mini greenhouse and place it in a warm area ( again around 65 to 70 point Fahrenheit ) . Keep the substratum consistently and evenly moist until germination — which may take 6 calendar month to a year . If after 2 month , none of the seeds have germinated , you may put the entire tray in the icebox for another 4 to 6 week and double your initial operation . Once the seedling emerge , if you’re able to , let them get in a greenhouse for their first winter and then place them in the ground in late spring or early summertime .
