Tweedia caerulea syn. Oxypetalum coeruleum
Blue Tweedia
Tweedia caerulea is a straggling evergreen perennial with heart shaped, gray-green, downy leaves. It is grown for its clear pale blue, star-shaped flowers, which are long lasting and cut well. The summer flowers age to purple and are followed by 30cm long, boat-shaped seed pods. The seeds have downy parachute-like tufts. Not the sort of plants to be grown outside where there are likely to be frosts. These plants need to be grown in a conservatory or cool greenhouse or at least brought inside for the winter
