Gardener's HQ Guide to Growing Heart Pea

Cardiospermum is a half hardy perennial, though gardeners often treat it as a half hardy annual.

It is a climber that may grow to 4 M in height.

Cardiospermum flowers in the summer with white flowers and has green fruit.

Other names for this garden plant include heart pea, Heart seed, Balloon vine (Cardiospermum halicacabum), Love in a puff, and Winter Cherry.

How to Grow Heart Pea (Cardiospermum)

If planning to grow Cardiospermum outdoors it is best to sow out the seed after the last frost of spring at a depth of 12 mm (1/2 inch) into well drained soil.

If you plan to grow heart pea seedlings indoors first then the seed should be planted about eight weeks before it is due to be planted out in the middle of spring.

Germination of heart pea should take place at about 20°C and takes from three to four weeks.

Seedlings should be transplanted into a sunny area of the garden at a spacing of around 60 cm (two feet).
