If you want to add a little something to your garden this weekend, Cal Poly students may have what you’re looking for. Cal Poly students will be selling more than 100 varieties of succulents, a total of 4,000 plants, at its two-day Succulentopia sale. The student-run project, which was held for the first time last spring, is run by five students and offers a variety of plant sizes. The sale will be held at the Horticulture Unit near the Poly Plant Shop from 10 a.m. to 6 p.m. tomorrow and 9 a.m. to 1 p.m. on Saturday
