Lewisia tweedyi-Tweedy’s Lewisia

Propagating what I believe is one of the most colorful perennials, born and bred in the USA, Pacific Northwest, and a cinch to propagate is lewisia. When I say to propagate you remove the off-sets or pups, what brings to mind are strawberries. You remove the umbilical cord that runs from the parent to the “baby” and plant. Varieties range in color from white, pink, coral and yellow and prefer a soil drainage of crushed gravel because the crown will rot if too damp. Also like most colorful perennials lewisia attracts snails, slugs, aphids and mealy bugs. It also prefers morning sun, average moisture, and planting beneath a well drained dripline is optimum. It will bloom from mid spring until early summer, reaches a height of 6-12", is evergreen and will grow in Zones 5-8. Be aware deer love to snack on it!

Camelina sativa-Camelina

This is an annual, basically a weed, that is used for biodiesel in planes/jets. It is primarily grown in Northern States because it cannot withstand the heat of summer. In Florida and Georgia they plant it as a winter crop, in by December out by April. It will flower in 85-100 days and it’s the seed heads that are used to make fuel. One acre makes about a gallon. Honeywell got FAA permission to fly to the Paris air show on camelina. They farm it in Montana and have a plant that makes into fuel in Houston. The plant itself has been around since the Bronze age and is native to Northern Europe. It is also used as feedstock. Ethanol as you know is from corn which feeds the world and that’s why some like Camelina. A 50 pound bag of seed can cover 5 acres and the cost to covert runs about $60, however because the seed has about 40% oil, and rich in OMEGA-3 fatty acid, it needs to be stored at 8% humidity or lower or else it becomes combustible and it’s the carbon the plant absorbs that makes it so valuable. It takes in more then is burned in a flight. It grows up to 3' and is in the mustard family.
