I added agapanthus to my border this year and it comes with no regret. Tall flower spikes of purple and white blooms have been a joyful sight, flowering from late spring through summer. Now that they have faded, I've been wondering whether I need to winterize agapanthus?
If you also grow agapanthus, this is a key thing to find out. The truth is, you only really need to winterize agapanthus if you live in US hardiness zone 7 or below. Milder climes can get away with minimal protection for these perennials, though it is advised to cut back spent flower spikes. Likewise, even if you do live in US hardiness zone 8 or above, you may want to consider providing some light frost protection (like mulching) if you have frosty periods forecasted, to ensure your agapanthus returns reliably next year.
