About this plant
This perennial sweet pea climbs quite vigorously to 2m (7ft), producing large, pretty, purple-pink, pea flowers. The leaves are long, narrow and dark-green. It lacks fragrance but has the same charm as the annual sweet peas. It is an old cottage garden favourite and was often found growing through an aged fruit tree.

Spring
Spring-Autumn · Outdoors
Water to keep the soil moist
For best results, this plant needs soil that is always moist. Water deeply and regularly as soon as soil appears dry. Even for established plants in the ground, a dry week can cause problems with some soils. Check plants in pots more often, especially in hot weather. Or install an automatic irrigation system which will do the hard work for you, even when you are away on holiday.
Without regular watering some plants never fully regain their beauty.
Spring-Winter · Planting
Tie branches to supports
This plant is usually grown up walls, trellis or fences. Since the plant cannot naturally support itself, it needs to be fixed to wires or other supports attached to the wall, trellis or fence.
The plant is most attractive when trained or it can become ugly with bare-stems. Use string or 'soft fixings' to attach the branches to the wires or supports on walls, trellis or fences.
Summer
Summer - early · Outdoors
Apply slow release fertiliser
Apply a slow release fertiliser which is spread around the root area of the plants soon after they have come into growth. (Or apply a liquid feed at regular intervals throughout the growing season.)
This is a simple way to provide a nutrient boost as a single annual procedure.
Planting & general
Planting
Deadhead blooms during flowering season
Remove flowers as they turn brown and fade. Snip the stem just below the bloom. This will keep the plant tidy and encourage more flowers.
The removal of spent flowers encourages the plant to produce fresh ones, rather than spend its energy on the development of seeds.
Compost · Planting
Multi-purpose compost
Use a good quality peat-free multi-purpose compost when growing in pots and containers.
