‘Twist N Shout’ is the most powerful rebloomer we have evaluated to date at Heritage, and we have not as yet conducted any new growth pinch pruning to accelerate reblooming. However, we will be conducting trials going forward to evaluate stem branching and overall plant form modification.
As already mentioned, ‘TNS’ has prospered in a broad range of photoperiod exposure. Planting sites range from ‘sunny’ (6 to 8 hours of mid-summer sun) – to ‘shady’ (2 to 3 hours of sun, shade density of 40 to 50%). Foliage has been clean in all locations with the possible exception of one small almost full sun location were the associated general stress is reflected in less than ideal leaf surface vigor. Inadequate surface irrigation is suspect in this instance; irrigation zones must reflect specific locations for best results.
Disease & Pest Attack
Chilli Thrips are a concern as previously discussed, but their presence has been not been detected on any Twist N Shout™ plants to date.
Previous comments on leaf spotting is consistent with ‘Twist’. The plant also loses its leaves somewhat earlier than most of the H. macrophylla cultivars.
General Growth Characteristics
Twist N Shout™ is a strong grower attaining 5 ft height and width in 4 years with surface irrigation. Plant form is somewhat random with a network of long non-branching stems of only modest density. This non-branching habit also produces low-lying stems which too easily root in the surface mulch creating ‘Volunteer’ plants.
