Tropaeolums for the Alpine House
Over the past few
years I have grown the following Tropaeolums in my unheated greenhouse.
|1) Tropaeolum azureum|
|2) Tropaeolum beuthii|
|3) Tropaeolum brachyceras|
|4) Tropaeolum hookerianum ssp. austropurpureum|
|5) Tropaeolum hookerianum ssp. hookerianum||
|6) Tropaeolum hookerianum ssp. pilosum|
|7) Tropaeolum incisum||Growing but not flowering
|8) Tropaeolum looseri||Growing but not flowering
|9) Tropaeolum nubigenum
||Growing but not flowering
|11) Tropaeolum rhomboideum|
|12) Tropaeolum sessilifolium||
|13) Tropaeolum tricolorum|
One of the major
problems in growing these plants is the reluctance of their tubers to come
back into growth after the summer rest period. This of course means that
it is necessary to sew seed regularly in order to maintain my collection.
This season has however been reasonably successful with seven of the thirteen
listed above in growth by late November. Sadly Tropaeolum hookerianum ssp.
pilosum has been lost but Tropaeolum rhomboidium remains as a healthy but
non growing tuber.
