Growing conditions and Care
Thelionema are a tufted clump forming perennial that will grow well in a rock garden situation.
They require a well drained soil, however growing amongst rocks they do obtain some moisture from beneath the rocks, so a little extra water during hot dry periods will be beneficial.
Thelionema can be grown from seed, but are a little difficult and slow. Larger clumps can be divided in winter to early spring. All species are well suited to a rock garden situation
- Full Sun
- Well drained soil
- Good organic matter in the soil
- Native plant fertilizer in late winter
- Remove dead foliage to tidy up
- Maintain moist soil through first two summers to aid with establishment.
Thelionema look good in the garden border where some varieties add good height. They grow well near the margins of ponds and are suited to growing in containers.
These are a decorative perennial plant that grow in clumps, flowering early to mid summer with flowers on long stems, deep blue to purple flowers, if you can find the white forms they are worth the effort. Full sun and a well drained humus rich soil. Keep moist while establishing.
