Eucomis may deter what they call "moles" in South Africa (which Rogan identifies as "mole-rats", apparently a rodent rather than an insectivore), but they have no similar effect on actual moles or on voles (rodents), both of which frequent my Eucomis planting area. That said, it's still a great genus to grow, in part because most (all?) of the species are winter-dormant and therefore can survive fairly cold winters in North America, especially if you plant them deep and mulch over them. However, as Rogan implied, the foliage is large and floppy, so Eucomis need their own space. An added advantage of the genus is that it seems to be very easy to grow from seed. The purple-foliage forms that are becoming popular seem to need full sun to maintain their best color, at least here in the cool Pacific Northwest. Jane McGary Northwestern Oregon, USA
