H.angusta is from stricta group where it has white sepals engulfing by red perianth or cheek. It is erect with red bright colours. The other one is H.psittacorum variegated Lady Di. The foliage is variegated and very attractive. it is very expensive when I bought that time and quite rare. It can be planted in the open sun.
Heliconias need fertilizers not only organic but also foliar fertilizers. Make sure your soil has the correct pH other the leaves will show some symptoms.
