Tropaeolum Azureum

Description

The extremely rare and absolutely fabulous blue climbing nasturtium has thin twining stems which produce solid sheets of dazzling cobalt blue flowers from the leaf axils of delicate, attractively-lobed leaves. One of the most astonishing perennial plants of dry places in Chile, it dies down to deep resting tubers in winter which are best kept dry. It is one of the absolutely ultimate alpine house plants. We have been advised that this seed will possibly not be available after next year.

Sowing Advice

Sow seeds at any time onto a good, damp soil-based compost, covering seeds to approximately their own depth. Keep the seed tray below 5 degrees C for many weeks, as these seeds are cold-germinators and can be extremely slow and erratic in germinating, sometimes waiting for spring before emerging. Do not try to force germination with heat, IT WILL NOT WORK. Do not discard the seed tray for at least a year. Grow on in 3 inch pots, do not over water. Plant with climbing support in a well-drained spot or very large pot.
