TROPAEOLUM POLYPHYLLUM

Description

Billowing trails of blue-grey leaves cascade along the ground or scramble through undergrowth, followed by an overwhelming display of golden yellow ochre flowers opening in June. This gorgeous plant is astonishing when its deeply tunneling hardy roots are established on a hot well-drained bank and although it improves quite slowly over the years it is well worth the wait. Few good seeds available.

Sowing Advice

Sow seeds at any time onto a good soil-based compost covering seeds with fine grit or compost to approximately their own depth. We recommend germinating at 15 to 20 degrees C. Germination may be very slow, perhaps 2-3 months, or sometimes much longer, and these seeds may sometimes wait for spring before emerging. Grow on individual seedlings in 3 inch pots before finally planting with climbing support in a well-drained spot or very large pot.
