1. False. Cit­rona is a ge­net­i­cally mod­i­fied gera­nium (pelargo­nium) plant ca­pa­ble of pro­duc­ing small amounts of cit­ronella, and it was de­vel­oped to keep mos­qui­toes at bay. De­spite favourable re­ports from some con­sumers, sci­en­tific test­ing shows it does not keep mos­qui­toes away from an area.

2. True. In a con­fus­ing twist of lan­guage, the plant we reg­u­larly re­fer to as gera­nium—that highly scented beauty so pop­u­lar in win­dow boxes— is ac­tu­ally botan­i­cally known as Pelargo­nium and the fab­u­lous shadetol­er­ant ground­cover we call cranes­bill is tech­ni­cally Gera­nium. They both come from the fam­ily Gera­ni­aceae, and both were con­sid­ered Gera­nium un­til 1789. See? Life re­ally was sim­pler in the olden days!

3. False. There are about 900 vari-

eties of salvia world­wide.

4. True. If you're look­ing for hor­ti­cul­tural in­for­ma­tion about salvia on the In­ter­net, be pre­pared to weed through many sites de­voted to use of Salvia di­vi­no­rum as a recre­ational drug.

5. True. The plant, known as jim­son weed by ex­per­i­ment­ing teenagers in the US Mid­west, has been used as a recre­ational and sa­cred drug since an­cient times. Ex­per­i­men­ta­tion is per­ilous, though, and many peo­ple have died seek­ing the mag­i­cal ef­fects. Datura is a mem­ber of the night­shade fam­ily. 6. True. Tomato and potato are ed­i­ble mem­bers of the deadly night­shade fam­ily Solanaceae. The leaves of both plants are toxic. Other com­mon night­shade plants are petu­nias and to­bacco.

7. False. Sweet potato vine is the ac­tual fo­liage of sweet pota­toes. Pull up your plants in the fall and you'll see the sweet potato tu­bers grow­ing in the soil.

8. True. The frozen prod­uct la­belled "sweet peas" in the su­per­mar­ket is not the same thing as the beau­ti­ful and sweet-scented sweet peas twin­ing up your fence. Your gar­den sweet peas are toxic, though you would have to in­gest an aw­ful lot to get sick.

9. False. Scar­let run­ner beans are en­tirely ed­i­ble, al­though many gar­den­ers grow them just for their or­na­men­tal ef­fect.

10. False. Scar­let run­ner beans are ac­tu­ally ten­der peren­ni­als. If you took the time to lift and store the roots over the win­ter, as you might with dahlias, you could re­plant them in spring.
