Usually available: All year Life cycle: PerennialHeight: 2 - 2.5mPosition: Sun / part shadeSoil preference: Well drained Good to know before you plant: Buddleja is a vigorous grower with a shallow, spreading root system. Give it an open, sunny spot with room to grow, and keep it a metre or two clear of walls, paths and drains. Snip off the spent flower heads through the warmer months. This keeps it blooming and stops it setting seed, as Buddleja can self-seed into bushland in cooler districts.This is how we pack and send your Herb Plants to all states except TAS & WA You will receive - 1 Buddleja 'Black Knight' Herb Plant in a 50 X 75mm tube - General growing instructions All of our Herb Plants are grown organically with certified organic potting mixes and fertilizersBotanical Name: Buddleja davidii 'Black Knight' All information provided on this website is for informational purposes only.
