B. ‘Longstock Gem’ is a very early flowering Buddleja, flowering before B. alternifolia. The flowers are larger than B. alternifolia with a scent. Attractive oak shaped leaves which are alternate on some shoots and opposite on other shoots changing to maroon and yellow in the autumn.
It will make a large plant good for screening, remove all the old flowering branches. If it does become too large hard prune to the ground in June
This is a sterile Buddleja. DOES NOT SET SEED.
A hybrid between B. agathosoma x B. alternifolia made in 1998 by Peter Moore. A Longstock introduction.
