Tropaeolum tuberosum var. lineamaculatum 'Ken Aslet'

Tropaeolum tuberosum 'Ken Aslet' is an amazing climbing nasturtium with small, glaucous leaves and thin tubular orange flowers that glow in the low shafts of sunlight in the autumn - just the time when we crave bright colours. Try to get an annual climber: Cobaea scandens to climb with it for an incredible combo, and front plant it with Verbena bonariensis. A choice climber. Tubers need to be lifted and stored over winter or mounded with protective mulch.

Perennial Nasturtium. A hard to find day length neutral selection of this tuberous and perennial species which puts on a fantastic show in July to September. Typical T. tuberosum and its varieties bloom in October - November here which is just in time to get frosted but not this one. We can't tell you how many times we have acquired this clone only to find out that it was not the real thing and how delighted we were to see this in full flower one summer covering part of a wall on Bob and Annette Barca's potting shed on nearby Whidbey Island. Delighted not only to see the true 'Ken Aslet' but also in knowing that Bob and Annette are the very souls of generosity and true to form, early the following spring we were gifted with some tubers. The Royal Horticultural Society regards this as a selection of the variety lineamaculatum and granted this the Ward of Garden Merit. Ken Aslet was one of England's great gardeners and was the Superintendent of the Rock Garden and Alpine House at Wisley.

Long spurred orange and yellow flowers, late.

The tubers are edible on this very vigorous, climbing, perennial nasturtium with vibrant orange flowers in late summer. Give it good moisture, shade at its feet and something to climb and it will reward you all summer ... and feed you as well. Frost hardy in USDA zone 9.
