Buddleja x lewisiana ‘Margaret Pike’ bears spikes of yellow flowers early in the year. Proving to be tender the plant is best grown in a pot and given winter protection.
If you have the space in a frost free glasshouse or conservatory I recommend this Buddleja as it looks spectacular from late January to early March. Best moved outside for the summer months.
History
