Hi, Some aloes are deciduous in the wild, growing in summer rainfall areas and dying back in winter. They are typically hardy (as aloes go) for 2 reasons: 1) the top dies back and the root behaves like a bulb, and 2) they typically come from higher elevations. I am growing several species of these "grass" aloes and have found the, so far, to be easy and durable. They are not "bulbs," but because they die back to a perennial rootstock; because they leaf out in warm weather and have such wonderful flowers, I think of them as bulb-type garden plants. I purchased seed from Silverhill seed about 2 years ago of A. cooperi, A. ecklonis, and A. myriacantha (apparently these are the more easily found species). All of them should be hardy down to 15 F, and some are reported hardy in to zone 7. I'm not sure what is a grass aloe and what is a bulb aloe, but they are similar; it is my understanding that both are deciduous-but I'm not sure. I think that bulb aloes actually make a more pronounced storage organ. The leaves of grass aloes are succulent. Here, near Houston, TX, the 3 species from Silverhill germinated easily indoors under lights (room temperature), and grew easily. They really enjoyed our hot Texas summer, and the rain-never seeming to get too much water or sun. They responded well to fertilizer and really seemed to enjoy it when I moved them from seedling pots/media into a 90% mineral mix (30% lava rock, 30% perlite, 30% coarse sand, 10% humus). They are about 20-24 months old now and I've potted them up several times. I plan to keep to or 3 of each type and find homes for the extras. Last year I protected them from rain during winter; they never got bone dry due to splash and spray but the leaves mostly died down. This year I will let them stay out in the garden, in 1- or 2-gallon containers over the winter. Perhaps if we have mild frosts again they will remain evergreen or perhaps they will die down. They are such strong growers that I'm hopeful some will bloom next summer. If nothing else I want to try their pollen on the other aloes that tolerate Houston (e.g., maculata, arborescens, striatula).
