These babies add serious wow factor to your shaded to part shaded gardens! When they started sprouting, I couldn't remember what they were because the sprouts are very unusual looking (at least to me, but it was my first experience with them), but when the leaves unfolded, they took my breath away!

obviously some of these pictures are not 'Red Flash'. vossner's is a true one. this is a very large, almost leathery leaf cultivar and holds up to wind better than some thinner leaf cultivars.

I planted this caladium here in central SC, zone 8a, and to my delight it survived our cold winter-lowest temp 10f. They returned in mid May and now they are even more robust than last year.

I got this lovely caladium in the 2007 Caladium4Less coop and it performed beautifully. Many of the bulbs returned in 2008. Some of the leaves are as big as elephant ears!

After much research on many differnt websites, I identified this caladium as "Red Flash". It has hardly any white and is a sturdy caladium. The neighborhood's roaming cats haven't demolished it yet! Because it is heavily mulched with spahgnum moss (the kind you top off container plantings to hide the dirt), I do not have to worry about watering it all the time during the hottest part of the summer. In 108 degree temperatures this summer, it never skipped a beat (although I did provide it a little extra water, naturally). It is still performing excellently in October. We haven't had any "cold spells" yet.

'Red Flash' is a medium-height Caladium, with pink/red center with white splotches and surrounded by a wide band of green border.

Caladiums can be potted up in early spring, and kept in the greenhouse to get an early start on spring growth, or directly planted once soil is warm and danger of frost is past. Regular watering will keep them growing all season.

Lift tubers in the fall, and store in moist, cool (but not cold) peat or other medium. Or can be treated as a warm-season annual.
