I've tried growing Buddleja Buzz on my small balcony, and it’s been a fantastic addition! They are indeed compact compared to traditional Buddlejas and fit well in containers, which makes them perfect for small spaces. The flowers are just as vibrant and do a great job of attracting butterflies, so you're right on track with that expectation!
In terms of care, I make sure to use a well-draining potting mix to prevent root rot, which is crucial since containers tend to stay wetter than in-ground conditions. Adding some perlite or grit can help improve drainage if your mix feels too heavy. They like a sunny spot, so I’ve positioned mine where it receives full sun for the majority of the day.
As for pruning, I've found it beneficial to trim them back in late winter or early spring, just before new growth starts. This helps maintain their compact shape and encourages more blooms. It's a manageable plant, but keeping up with this yearly pruning is key to keeping them bushy and well-rounded.
One thing to consider is regular watering, especially during hot spells, because containers dry out quicker than the ground. But do be cautious not to overwater.
In general, Buddleja Buzz has been quite rewarding, and with a little care, I'm sure you'll enjoy it too! Have you decided on a specific variety, or are you exploring your options still?
