(shizomatous) The challenging yet famous "Iron Cross Begonia". Puckered quilted leaf surface with maroon chocolate central cross--the entire bullate leaf being reddish haired. A New Guinea native prefering terrarium humidity where it will produce its clusters of greenish white haired blossoms; not easily grown as a windowsill subject without pebbletray culture. Never give up if the "Iron Cross" foliage suddenly dries and disappears, random mini-dormancies are the norm (even in the greenhouse)--the succulent surface rhizomes will soon produce a new set of its remarkably beautiful leaves when its environment improves. If you need positive feedback on your prowess as a beginning Begonia grower, this is not a good selection for your first, second or third subject--once your growing skills are honed, try the ever tempting "Iron Cross," otherwise, you might consider yourself as nailed to a very stiff challenge.
Some of you grow only indoors, some only in terrariums; many of you have hobby greenhouses; while a growing number of customers live in subtropical or tropical areas of the world. These brief codes are an attempt to suggest whether or not a particular plant will do well in your particular conditions.
If an entry has the cluster HP CGH, this means normal house plant culture will be successful if the plant is given a cool CGH moist location; however if the entry has the cluster CGH HP, you would interpret this to suggest that while Cool Greenhouse conditions are needed for total success with this plant, House Plant conditions will be adequate, while not ideal. If the cluster is HH CGH you would interpret this to mean that while in Zone 8 or below this will be winter hardy outdoor, further north it will need considerable mulch, a cold frame, or a Cool Greenhouse to thrive. And so on.×
