NOW THAT THE HURRICANE IS OVER, HOW APPROPRIATE THAT THIS TROPAEOLIUM NOW BLOOMS – A FLAMING PHOENIX RISING, WITH ITS BRILLIANT YET SMALL SOUTH AMERICAN NATIVE, TROPAEOLUM SMITHII<\/i>, IS A RARELY GROWN SPECIES WITH A BRIGHT FLOWER. IT IS ‘GROWABLE’ AS AN ANNUAL FOR THE SUMMER GARDEN OR IN CONTAINERS, IF YOU CAN FIND THE SEED. ( TRY CHILTERN SEEDS<\/a> IN THE UK).<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
TROPAEOLUM ARGENTINUM, A BIT MORE REFINED AND DARE I SAY, A LITTLE ORCHID-ISH? THIS AIN’T YOU”RE AVERAGE CANARY VINE<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
\n We are all familiar with the more common Nasturtium majus, yes, those bright orange and yellow flowers found in edible flower packets and the annual with large seeds and tiny water-lily shaped leaves that are also edible and peppery flavored, often grown by children and new gardeners due to their high performance level. Easy, attractive and a long blooming season makes these annuals some of the best for filling annual borders, but these species forms are a bit more precious – they will do best if grown in containers and allowed to scramble over low shrubs, as they grow in the wild.<\/div>\n

EARLIER THIS SUMMER, YOU CAN SEE HOW SIMILAR THE FOLIAGE ON THIS T. SMITHII LOOKS TO THE GEOPHYTIC SPECIES, THE ONES THAT GROW FROM TUBERS THAT YOU CAN SEE IN MANY OF MY WINTER POSTS. THESE APPEAR TO BE A BIT MORE STURDIER, BUT JUST AS CHALLENGING TO GERMINATE, THE TRICK, IF ANY, APPEARS TO BE HOW TO KEEP JUST ENOUGH MOISTURE AROUND THE SEED WITHOUT CAUSING ROT. <\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

T. SMITHII GREW ON A SMALL TRELLIS IN A CONTAINER THAT I SET NEAR THE GREENHOUSE DOOR, IN A LARGE BAY LAUREL TUB. IT OUT-GREW THIS POT, CHOOSING TO REACH OVER TO A NEARBY SHRUB WHERE IT COULD TUMBLE AND GROW OVER.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

T.SMITHII SEEMS MORE NATURAL AND IN CHARACTER ONCE IT ESCAPES ITS POT. THE TINY 3\/4 INCH BLOSSOMS ARE ATTRACTIVE AND BRIGHT, LIKE ELF CAPS, BUT COLORED AS IF THEY ARE ON FIRE, A TONE DIFFICULT TO CAPTURE ON A DIGITAL CAMERA.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

THE TROPAEOLUM ARGENTINUM SEEDLING WAS PLANTED, AS AN EXPERIMENT SINCE I FOUND VERY LITTLE CULTURAL INFORMATION FOR IT) IN AN ALPINE TROUGH, SINCE IT WAS FAST DRAINING. IN JUNE, THE SEEDLING HAD ONLY A THIN, WIREY STEM WITH A COUPLE OF SAD LEAVES. THE BLOSSOMS ALMOST BECOME LOST IN THE SLIGHTLY YELLOWING FOLIAGE. UP CLOSE? VERY PRETTY.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

\n
I DON”T KNOW WHAT I WAS THINKING PLANTING THIS IN A TROUGH, BUT IN LATE JULY, THIS SPECIES TOO, TOOK OFF, ALMOST CONSUMING THE ROUND TROUGH. IF I GET SEED, I WILL FIND A BETTER PLACE TO GROW THIS. FOR NOW, I ALLOWED IT TO TUMBLE OVER SOME TWIGS FROM A NEARBY CRAMBE CORDIFOLIA SEED STALK, WHICH I PROVIDED AS A TEMPORARY TRELLIS.<\/p>\n
For information on other Tropaeolum species that I have grown over the past year, check out these posts from the winter, since this is the month when you can order and plant the tubers of these other South American species. I suggest Tropaeolum tricolor \n Tropaeolum tricolor, a tuberous species that can be grown as a winter-flowering plant for a cold windowsill or cold greenhouse. It grows from a small, potato-like tuber – order them now from finer bulb sources.<\/p>\n
